If there’s one shape that always grabs our students’ attention in geometry, it’s circles. Maybe it’s because they’re everywhere – from wheels and pizzas, to coins and cookies. Maybe it’s because circles feel a little mysterious with that never-ending number we call “pi”. Whatever the reason, teaching circles is one of those times in the year when math feels a little more engaging.

Circles can also be a bit overwhelming for our students. With new vocabulary, formulas to memorize, and the challenge of connecting it all together, circles take some extra practice to fully understand. The good news is that, with the right mix of activities, visuals, and hands-on tools, circles can go from intimidating to exciting.

Why Teaching Circles Matter

Circles aren’t just another geometry unit to check off. They’re foundational for so many math concepts our students will see later. Understanding radius, diameter, circumference, and area lays the groundwork for more advanced topics, from geometry proofs to trigonometry and even real-world applications like engineering or design. When our students really “get” circles, they’re better prepared to tackle more complex math down the road.

Teaching circles also gives us a chance to show our students how math connects to everyday life. Whether it’s measuring a round table, calculating how far a bike wheel travels, or figuring out how much frosting they need for the top of a cake, circles pop up everywhere. This makes it easier for our students to see the why behind their learning.

We can’t forget about confidence. Circles can seem intimidating at first. Once our students discover how approachable the concepts are, they build momentum. That confidence often spills over into other areas of math, making circles a powerful unit for boosting both skills and self-belief.

Using the Circles Math Wheel for Note-Taking

One of my favorite tools for teaching circles is the Circles Math Wheel. If you’re not familiar with math wheels, they’re a structured but creative way for your students to organize their notes. Instead of flipping through a notebook and trying to find definitions and formulas scattered everywhere, your students have everything about circles in one neat, interactive page.

The Circles Math Wheel has sections dedicated to pi, radius, diameter, circumference, and area. Each section includes space for definitions, examples, and practice problems. The best part is that there are different versions to fit your students’ needs. There is an “open” version for complete note-taking, a fill-in-the-blank version for guided support, and even a pre-filled option for your students who might have been absent or need extra scaffolding. This flexibility makes it easy to meet your students where they are.

Another benefit of the wheel is its creativity factor. Your students have the chance to color and doodle as they work. This not only makes the wheel more engaging but also taps into that stress-relief element of coloring and memory retention. It’s a graphic organizer that your students can keep in their notebooks for safekeeping. They can refer back to it when solving problems, and even use it as a study guide before tests.

Methods for Teaching Circle Concepts

When it comes to teaching circles, I’ve found that variety is key. You want to start with the basics by introducing circle vocabulary. Have your students physically draw circles, label radius and diameter, and use a string to measure circumference. These tactile experiences help concepts click before formulas even come into play. Once your students understand the vocabulary, then you can layer in the “why” behind the formulas for circumference and area.

The Circles Math Wheel supports this process really well. As you introduce each concept, your students can add notes, examples, or formulas to the corresponding section of the wheel. For example, when teaching circumference, show both formulas (C = 2πr and C = πd). Then, have your students work through sample problems right on the wheel. That way, they aren’t just copying notes. They’re actively applying what they’ve learned.

I also recommend mixing in games and activities. Circle scavenger hunts around the classroom, digital task cards, or even Pi Day celebrations can bring energy into your geometry lessons. The key is to keep your students engaged while reinforcing vocabulary and formulas. With the math wheel as their anchor, your students have a reliable resource to connect all these fun activities back to their core understanding of circles.

Activities to Reinforce Circles

Once your students have a grasp of circle concepts, it’s time to put their knowledge into action. Task cards with area and circumference problems are great for partner practice or stations. Color-by-number activities with circle problems can make review days more fun while still providing solid practice.

Another favorite activity is having your students measure real-world objects shaped like circles. You can use anything from bottle caps to hula hoops. They can measure diameters, calculate circumferences, and even estimate areas. This kind of real-world application helps them see that circles are everywhere in daily life.

Pi Day opens the door for even more activities. From circle-themed games to edible math with pies and cookies, it’s a perfect time to celebrate and practice. Pair these activities with the Circles Math Wheel so that your students not only enjoy the experience but also keep reinforcing their circle knowledge.

Teaching quadrilaterals in 5th grade doesn’t have to feel overwhelming or dry. With the right mix of strategies, you can help your students confidently recognize, classify, and compare quadrilaterals. You can even do all of that while keeping them engaged and excited. By focusing on the properties of quadrilaterals and showing how the different types of quadrilaterals connect, you’ll help them build a strong foundation in geometry that really sticks.

Start With Clear Definitions of Quadrilaterals

Before jumping into activities, it’s key to make sure your students know what quadrilaterals are. They are four-sided polygons with four angles. Once that’s clear, you can dive into the different types of quadrilaterals they’ll encounter. Show them examples of parallelograms, rectangles, rhombuses, squares, and trapezoids.

When you introduce the types of quadrilaterals, guide your students to notice what these shapes have in common and what makes each unique. For example, they’ll love the “aha” moment when they realize that all squares are rectangles, but not all rectangles are squares. This is the perfect chance to spark conversations about how shapes fit into a hierarchy and why it matters.

One simple but effective move is to use anchor charts or classroom posters. Label each type of quadrilateral and highlight its key properties. Then, place it right there on the wall or a bulletin board for easy reference. This visual support helps your students feel confident, especially when they’re working independently or in small groups.

In my room, my absolute favorite type of anchor chart is a math wheel. These helpful reference tools can be blown up to poster size or used on a regular-sized sheet of paper for student note-taking. When you display them up on a wall, you’ll have a vibrant and colorful visual record of everything you’re covering. More on math wheels for teaching quadrilaterals to come, so stay tuned!

Connect Quadrilaterals to Math Vocabulary Practice

Teaching quadrilaterals isn’t just about recognizing shapes. It’s also a great chance to strengthen your students’ math vocabulary. Words like “parallel”, “perpendicular”, “right angles”, “congruent”, and “diagonal” are all part of the conversation when exploring the properties of quadrilaterals. Making space to teach these terms can help your students better describe, compare, and explain the shapes they’re working with.

If your students struggle with grasping math vocabulary, I highly suggest creating a focus wall in your classroom. You can type up some definitions for each term and display them on the wall. This will serve as a helpful reminder to your students throughout your lessons.

Another simple way to build vocabulary practice is through matching games. For example, have your students match shape names to their definitions or match pictures of shapes to key properties like “two pairs of parallel sides” or “four right angles.” You can also create simple card games or partner activities where your students quiz each other on terms and give clues until their partner guesses the word.

Another fun idea is to have your students create their own illustrated math dictionaries. Ask them to draw each type of quadrilateral, label it, and write a quick description of its properties. Not only does this help reinforce new vocabulary, but it also gives your students a personal reference they can use during lessons and review time. By weaving in vocabulary practice, you’re setting your students up to communicate their thinking clearly and confidently. This is a skill that pays off across all areas of math.

Explore With Hands-On Activities

This is where the fun really begins! Giving your students the chance to cut, sort, draw, or build quadrilaterals brings the learning to life. Try handing out shape cutouts and asking your students to group them by properties. Think along the lines of how many pairs of parallel sides they have or whether they include right angles. As they sort, they’re naturally reinforcing what they’ve learned.

Geoboards or virtual drawing tools are another awesome option. Challenge your students to create different types of quadrilaterals and explain how they know which is which. For example, they might stretch a rubber band to make a parallelogram. After they do, they need to describe how they can tell it’s not just a random four-sided figure. It’s a great way to get them using precise math language in a low-pressure, creative way.

Remember to share some real-world connections, too! Send your students on a “quadrilateral hunt” around the classroom or school. Let them snap pictures or sketch examples of quadrilaterals they spot in floor tiles, windows, books, or bulletin boards. Suddenly, geometry isn’t just something from a textbook. It’s everywhere they look.

Break Down Quadrilaterals With the Math Wheel

If you’re looking for a tool to pull all this learning together, my Quadrilaterals Math Wheel is a total game-changer. This interactive resource walks your students through the types and properties of quadrilaterals in a way that’s both structured and fun.

Each section of the wheel focuses on a specific shape, such as a trapezoid, a parallelogram, a rectangle, a square, or a rhombus. It also includes a general section for quadrilaterals. As you work around the circle, your students jot down key characteristics, like parallel sides, equal-length sides, or right angles. You can choose how much support they get with open notes, fill-in-the-blank notes, or pre-filled notes for your students who need a little extra help.

Around the edge, there’s a set of true/false statements to challenge students’ thinking. They’ll get to test their understanding of tricky concepts like “A rectangle is a square” or “A rhombus is a parallelogram.” These are perfect for sparking class discussions or partner check-ins. There’s also built-in doodle space, so your students can color and personalize their wheels while they work, adding a creative twist to help them retain this math concept.

Why the Math Wheel Helps Master Quadrilaterals

What makes the Quadrilaterals Math Wheel so effective is how it blends note-taking, visual organization, and active practice. Instead of just memorizing definitions, your students are building a hands-on reference tool they can keep coming back to. Plus, you get to decide how to use it – for the whole group, a small group, or an independent review. And don’t forget about the option to make a large anchor-chart style math wheel, too!

Your students will love that the wheel feels interactive and creative. They’re not just sitting and listening. They’re engaging with the material, coloring, labeling, and making sense of the relationships between different shapes. The true/false section is especially useful for clearing up common misunderstandings. This helps your students feel more confident tackling practice problems and assessments.

For you, teachers, the math wheel is a huge time-saver. It’s ready to go, easy to adapt, and flexible enough to fit into any lesson plan. Whether you’re introducing quadrilaterals for the first time or reviewing them before a test, this tool helps make sure the properties and types of quadrilaterals really stick.

Review Quadrilaterals With Games and Movement

Take your quadrilateral lessons up a notch by bringing in some games and movement! Adding active review activities helps keep your students engaged and gives them a fun way to practice what they’ve learned. It’s a great strategy for kinesthetic learners, but honestly, all students benefit from getting out of their seats and playfully applying their knowledge.

One favorite is Quadrilateral Bingo. Create Bingo cards with the names or pictures of different types of quadrilaterals. Then, call out properties like “four congruent sides” or “only one pair of parallel sides.” Your students have to think carefully about which shape matches and mark it on their card. It’s fast-paced, interactive, and perfect for small groups or whole-class review.

You can also set up a “Four Corners” game by labeling each corner of the room with a quadrilateral type, such as square, rectangle, parallelogram, rhombus, or trapezoid. Read out clues or properties, and have students move to the corner that matches. It gets them moving, but it also gives you a quick check on how well they’re grasping the concepts. By mixing in games and movement, you make practicing quadrilaterals something your students will actually look forward to!

The post Easy and Effective Ways to Teach Quadrilaterals in 5th Grade appeared first on Cognitive Cardio Math.

Teaching geometry was one of my favorite 6th grade units because it blends logic, creativity, and real-world applications. Something was exciting about seeing my students go from memorizing formulas to understanding how shapes and space work together. Whether they’re breaking apart polygons, calculating the surface area of a gift box, or figuring out how much space a storage bin takes up, these skills give them a whole new way to see the world around them.

Today, I’m sharing the unit that made teaching geometry fun and effective. From hands-on foldable activities to coordinate plane challenges, real-world word problems to interactive notes, the activities in this unit make learning feel like a discovery, rather than a drill. By the time we wrap up, they aren’t just solving for area and volume. They’re thinking critically, problem-solving, and making connections to everyday life.

The “Why” Behind Teaching Geometry

Why is learning about geometry, specifically area, surface area, and volume, so important? It’s more than just plugging numbers into formulas. These concepts are the foundation for so many real-world skills. Whether our students realize it or not, they’ll use geometry in everything from designing a school project to figuring out how much paint they need for a wall.

Understanding area helps our students break down space efficiently. This is useful for arranging furniture in a room or laying out a garden. Surface area plays a role in wrapping gifts, designing packaging, or even predicting how much material is needed to build something. And volume? That’s everywhere, like packing a suitcase, measuring ingredients for a recipe, or determining how much water fits in a swimming pool.

Teaching geometry strengthens our students’ spatial reasoning and problem-solving skills. It encourages them to visualize, plan, and think critically. These are key skills that go beyond math and into STEM fields, architecture, and even art.

Unit Plan for Teaching Area, Surface Area, and Volume

Geometry is one of those subjects that naturally spark curiosity. From the patterns in nature to the designs of buildings and everyday objects, shapes and measurements are all around us. That’s why teaching geometry to our 6th graders needs to be more than just learning a formula. It’s about helping our students see math in action.

In this Geometry unit, the focus is on three key concepts: area, surface area, and volume. Each one builds on the others, giving your students a well-rounded understanding of how to measure and calculate space. You will start with the basics, exploring polygons and their properties, then move into surface area with nets and real-world applications. Finally, you’ll tackle volume, helping your students visualize and calculate the space inside 3D objects.

Throughout the unit, you’ll be able to incorporate interactive notes, hands-on practice, and engaging challenges that push your students to think critically. Instead of memorizing formulas, they explore why they work and apply them to real-world problems.

Laying the Foundation for Teaching Geometry

Before diving into formulas and calculations, you want to make sure your students have a strong foundation in key geometry vocabulary. This is where the Geometry Word Wall​ comes into play. You can display essential terms, like quadrilateral, trapezoid, vertex, and edge, so your students can easily reference them throughout the unit. This helps reinforce vocabulary in a way that feels natural rather than forced. Instead of constantly repeating definitions, you can encourage your students to use the word wall when working on problems, discussing, or explaining their reasoning.

Once your students are familiar with the terms, you can move into the student packet​, which is packed with guided notes, graphic organizers, and foldables that break down key concepts. You’ll love using foldables because they make abstract concepts more tangible. Your students cut, fold, and manipulate paper to reveal information step by step. These interactive elements transform note-taking from a passive task into an active learning experience. Instead of simply copying formulas, your students work through structured examples, reinforcing their understanding before practicing independently.

Exploring Area When Teaching Geometry

To introduce area, you can start with rectangles and squares. These familiar shapes make it easy for your students to see how multiplication plays a role in finding the area. Once they’re comfortable, you can expand to triangles, trapezoids, and parallelograms. By using the area graphic organizer,​ students can compare and contrast formulas.

Students will learn to decompose shapes to find their area. I have found that modeling this a couple of times helps them quickly see the strategy and how they can use it to break down irregular figures into known shapes. This strategy helps with geometry and strengthens problem-solving skills they’ll use in algebra and beyond.

A favorite part of this unit is the coordinate plane activities. Your students will plot points, connect them to form polygons, and then determine their area. This is a great way to bridge geometry and graphing, reinforcing their coordinate plane skills while making math more hands-on. You’ll love how these activities build spatial reasoning and give your students a new perspective on how geometry applies outside of isolated shape calculations.

Teaching Geometry With a Focus on Surface Area

Surface area can be tricky for some students, so you want to make sure they see how 3D shapes unfold into nets​ before expecting them to apply formulas. I start with physical models, giving students cut-out nets of cubes, rectangular prisms, and pyramids. They fold these into solid figures and then unfold them to see where each face comes from. This hands-on activity makes it much easier for students to visualize and calculate surface area.

Once your students grasp the concept, you can introduce the graphic organizer and practice pages​ to solidify their understanding. Some of your students will prefer working with nets. Others find formulas more efficient, so just make sure they practice both methods.

A game-changer when teaching geometry is the review coloring sheet included in the unit​. Your students will solve surface area problems. Then, they will use their answers to determine which colors to apply to different sections of an image. This makes practice more engaging and provides instant feedback. They know to check their work if their answer doesn’t match a color. It’s a low-pressure, high-engagement way to reinforce learning.

Bringing Volume to Life When Teaching Geometry

Volume can feel abstract to students, so I like to connect it to real-world objects. You can start with rectangular prisms, using unit cubes to physically build different shapes and count how many cubes fit inside. This concrete representation helps your students see volume as more than just numbers on a page.

As you transition to formula-based calculations, you can integrate real-world word problems. Your students will calculate the volume of fish tanks, storage bins, and gift boxes, helping them understand how these concepts apply to their lives. These problems push your students beyond simple plug-and-play formulas. It encourages them to think critically about dimensions and units.

To keep your students engaged and ensure they’re grasping the material, make sure to use exit tickets​ at the end of lessons. These small, daily check-ins ensure your students aren’t just memorizing formulas. They’re understanding how and why they work. The quick checks allow you to pinpoint misconceptions and adjust instruction as needed before moving forward.

Assessing Understanding

By the end of the unit, your students will be ready to demonstrate what they’ve learned through a geometry test​. This assessment includes a mix of matching definitions, calculating area and surface area, and solving multi-step word problems. By this point, your students have built confidence in their skills. You’ll be able to see how they tackle these problems with a deeper understanding than when you started.

Supplementary Resources for Teaching Geometry

In addition to the core components of this unit, I loved incorporating a variety of supplementary resources to reinforce key concepts and keep my students engaged. Below are a few examples of materials that can support you when you are teaching geometry. These resources provide additional practice and different ways for your students to explore area, surface area, and volume.

Volume Color By Number

One of my favorite activities I used to keep my students engaged while practicing volume calculations was my Volume Color by Number worksheets. This resource blends math practice with creativity, turning problem-solving into a fun and approachable experience.

Your students begin by solving problems related to finding the volume of rectangular prisms and composite figures. Each correct answer corresponds to a specific color, which they then use to complete a coloring sheet. This self-checking approach makes practice more engaging and provides immediate feedback. If an answer doesn’t match the expected color, students must double-check their work.

This resource also includes multiple worksheet versions with different levels of complexity. This includes whole-number and decimal-based problems. It also offers customary and metric unit options so your students can practice using different measurement systems. The digital version in Google Slides allows your students to complete the activity online by digitally filling in their answers and coloring.

Surface Area Footloose Task Cards

One of the best ways to keep your students engaged while practicing surface area calculations is through Surface Area Footloose task cards. This activity gets your students up and moving while solving problems. It makes it a great way to reinforce concepts without feeling like traditional seatwork.

Your students start with a grid where they record their answers. They each receive one of 30 different task cards, which include problems requiring them to find the surface area of various shapes. Some problems ask your students to determine missing dimensions based on given surface areas. This adds a layer of critical thinking.

Instead of sitting at their desks completing a worksheet, your students move around the room. After solving a problem, they place their card back in a designated spot and pick up a new one. This helps keep energy levels up and encourages your students to stay engaged. The answer key and doodle notes provide additional reinforcement, allowing your students to check their work and review key concepts.

Area and Perimeter Practice With a Truth or Dare Twist

Bringing a game-like element when you are teaching geometry always keeps your students engaged. Area and Perimeter Truth or Dare is one of those resources that turns practice into a fun challenge. Instead of a traditional worksheet, your students choose between Truth or Dare question cards. They then solve problems related to area and perimeter while competing for points.

The Truth cards focus on quick, conceptual questions. Your students might need to determine whether a statement about area or perimeter is true or false or solve a basic calculation. The Dare cards push them a little further by requiring more complex problem-solving. They might have to find a rectangle’s missing side length, given its perimeter, or solve a real-world application problem. Dares are worth more points, adding an extra layer of strategy to the game.

You can have your students work in small groups, rotating turns and recording their answers on a Truth or Dare recording sheet. The structure encourages discussion, collaboration, and critical thinking. Your students will often have to justify their reasoning when solving for missing measurements. Groups can check answers by designating an “answer checker” or using the included answer key at the end of the game.

The post Engaging & Effective Activities for Teaching Geometry in 6th Grade appeared first on Cognitive Cardio Math.

One of my favorite memories teaching math was whenever my students started seeing math in their lives. One of the most common topics this would happen with was when I was teaching the different types of angles. I loved seeing their excitement as they started noticing angles in everything around them, from the corners of a book to the hallways they walked down. Today, I’m sharing a math doodle wheel, along with quick activity suggestions, to make teaching the different types of angles effortless.

Benefits of Knowing Types of Angles

Understanding the types of angles opens up a whole new way of thinking for our students. They’re learning how to “see” geometry in the real world. When they understand different types of angles, they connect classroom learning with everyday objects and spaces. It’s amazing to watch them go from staring at a textbook diagram to pointing out angles in their favorite video games or the shape of their kitchen table. This real-world connection makes the concept relevant and shows them why math truly matters.

Another key benefit is that knowing the types of angles strengthens their overall math foundation. Angles are everywhere in future topics, from polygons to measuring rotation. Having a solid grasp of these early concepts makes tackling more complex math much easier. It also helps with logical thinking! When our students identify, measure, and even draw angles, they practice skills that improve their attention to detail and ability to analyze shapes and sizes. These skills are useful for other subjects, too. Think science and even art!

And, of course, the confidence boost is huge. When our students recognize a 90-degree angle or can spot an angle that’s greater or less than that, it makes them feel capable and curious. They become more observant, spotting everyday angles and analytical – they can figure out how different shapes and lines relate to each other. So, learning the types of angles helps them become sharp, observant thinkers excited to apply what they know outside the classroom!

What Are Math Doodle Wheels?

Math doodle wheels are hands-down one of the most fun and effective note-taking methods I’ve created for my math class! These math wheels are engaging in a world where traditional note-taking can sometimes feel a bit stale. Math wheels change the game. Each wheel is a graphic organizer that lets our students take notes, practice problems, and even color and doodle to help solidify what they’re learning.

Math wheels make learning math memorable. Our students write key concepts inside the wheel, add their colors and doodles, and work through problems in a fun pattern around the wheel. It’s hands-on, it’s creative, and it’s brain-friendly! Research shows that using color and visuals boosts memory, so when our students interact with math wheels, they’re engaging both sides of their brains, helping them truly absorb the material.

Math wheels are also super versatile. I can use them with the whole class, in small groups, or even as independent practice. Plus, they make fantastic reference tools that our students can return to whenever they need a refresher. The customization options are endless. There are wheels for everything from multiplication to problem-solving strategies, so they’re great for various topics. Math wheels bring the “wow” factor to math note-taking, keeping our students engaged, organized, and excited about learning.

Types of Angles Math Doodle Wheel

When it’s time to teach students about different types of angles, the math wheel can be a great starting place. With each section, the Types of Angles math doodle wheel is a visual and interactive structure that helps make learning the types of angles an enjoyable learning journey for your students. It combines both visual and hands-on elements to reinforce each concept! You can use these math wheels to introduce topics or to review. Let’s take a look at the breakdown of each section.

Angle: Definitions and Examples

This first section introduces the concept of an angle as two rays with a common endpoint called the vertex. This is also the time to introduce them to the term ‘degree’ and discuss how we measure angles. Have your students write down the key definitions, label the rays, and draw examples of different angles. This hands-on labeling helps reinforce these essential terms.

To make it engaging, ask your students to find objects around the classroom with similar angles or use their fingers to form different angles. You can also have some real-life photos that show angles. This makes the types of angles feel real and relevant.

Measuring Angles

In the second section, your students will learn what it means to measure an angle and how to use a protractor. Give a quick demo of aligning a protractor with an angle. Then, let them draw angles on their math wheels. They can place the vertex on the center of the protractor and measure the degrees between the rays.

This is also the perfect time to add in some connections. Make sure to point out that a whole circle is 360 degrees and that a straight line is 180 degrees. As students learn this, they can make the connection of smaller angles in relation to a line or circle.

To get students used to reading the angles on the protractor I like to play a little game. I call out an angle using the number of degrees. Students use the diagram on the math wheel to find the angle. Then they stand up and make that angle with their arms. It’s a fun activity that will get your students immersed in the world of angles and degrees.

Acute and Obtuse

This part of the wheel provides definitions and space for examples of acute and obtuse angles. Explain that acute angles are less than 90 degrees and obtuse angles are greater than 90 but less than 180 degrees. Have your students draw their own examples of each type within the wheel. They can label them and even add color to distinguish between the two visually.

To help kids remember the difference between the two types of angles you can give them some word cues. Since we are comparing angles to a 90 degree right angle you can start there. You could tell them that angles that are smaller than 90 degrees are little and “cute” like a baby. Then move on to obtuse angles. You could talk about the word ‘obese’ and how it begins the same way as ‘obtuse.’ Then make the connection that angles bigger than 90 degrees are called obtuse angles.

To make it memorable, let them color-code these angles to keep the information visually different. You might even add a quick game where students flash their hands to show different angles. You can also have them “vote” if an angle is acute or obtuse based on your drawings.

Straight and Right

In this section, your students learn about right angles (exactly 90 degrees) and straight angles (exactly 180 degrees). They can add examples and visually mark the 90-degree and 180-degree angles within the wheel. Connecting this new knowledge to the world around them is a great way to connect these terms in their mind. Have students look around the room and point out straight lines and right angles. They will be amazed that they are everywhere!

Benchmark Angles

This section includes 30, 60, 90, and 180 degrees benchmark angles. These are key reference points in understanding angles. Have your students label and color each benchmark angle within the wheel. You can explain that these benchmarks help us estimate angles without needing a protractor every time.

Challenge your students to identify or “eyeball” these benchmark angles on their own. Then, measure with a protractor to check their guesses. Practicing with these angles gives them confidence and a good foundation for understanding angle measurement.

A great way to do this is to go on a scavenger hunt looking for angles in the classroom or hallway. Have students look for an angle that is “about 30 degrees” or “about 60 degrees.” Once they find one, let them use a protractor to measure it and see if they are right.

Practice Problems

In the last section, the wheel offers practice problems to apply what your students have learned. You’ll find a word problem that encourages your students to measure and identify angles. It’s a great way to explore the concept of angle addition, such as decomposing a larger angle into smaller parts or creating a larger angle by adding two smaller angles.

I love to illustrate this with the most well-known 90 degree angle. I draw a 90 degree angle on the board in one color and I have the students identify it. Then I use a different color to divide that angle into 2 or more angles. Students can see that together, those smaller angles still make a 90 degree angle. It’s a great way to dive deeper into adding angles and decomposing angles.

To finish up this concept, ask students to create a 120 degree angle using 2 or more smaller angles. When you have them share their answers, have them demonstrate the total number of degrees using addition. Not only does this reinforce the concept but it also lets students see that there are many different ways to create the same angle.

After Finishing the Types of Angles Math Doodle Wheels

After each section of the wheel is filled in, your students can dive into the additional practice problems placed around the edges of the wheel. These extra angles let them apply what they’ve learned, identifying, measuring, and classifying each angle. It’s a fantastic way to review and reinforce their understanding as they determine which angles are acute, obtuse, right, or straight. Then, they can get some extra measuring practice by using a protractor.

Adding color is a powerful step for retention, and it makes the wheel visually engaging. Encourage your students to use different colors for each type of angle, add background colors, or fill in the letters. Color-coding and filling in the sections of the wheel help each angle type stand out in their memory. Completing this colorful step after the practice problems brings in a creative twist that reinforces learning.

Once completed, your students should store their math wheels in their math notebooks or binders. This keeps their wheel protected and easily available as a reference throughout the year. Attaching it to the inside cover of their notebooks is a great way to make sure they can quickly find it whenever they need a refresher on the types of angles. This simple tool becomes a go-to resource for them to revisit and use confidently as they build on their geometry skills!

Being Successful With Types of Angles

Teaching the types of angles doesn’t have to be a challenge. It can be one of the most engaging parts of math! Using interactive tools like the angles math wheel gives our students a way to see, touch, and memorably understand each angle type. From measuring angles to spotting them in the real world, every section of the wheel helps build their confidence and deepen their understanding. I hope this approach gives you fresh ideas and inspiration to make angles come alive in your classroom. Let’s help our students not only learn the types of angles but also get excited about finding them all around!

Through my years of teaching, I quickly discovered that the more interactive I could make learning about volume, the better. Volume can be intimidating for some of our students. So, it’s important to make sure to break it down into simple steps. There’s also something really exciting about seeing our students connect the dots and understand concepts like the volume of a cone, the volume of a cylinder, and the volume of a sphere beyond just plugging numbers into a formula. Today, I’m sharing with you volume activities that will help you teach the volume of different shapes to your students!

Importance of Volume Activities

When we dive into volume activities with shapes like cones, cylinders, and spheres, we do more than learn formulas. Understanding the volume of a cone, cylinder, and sphere gives our students a new lens through which to see the world. These shapes pop up all around us. Think about ice cream cones, soup cans, basketballs, and even planet Earth! Knowing how to calculate the volume of these shapes helps our students make sense of the objects they interact with daily.

If they know the volume of a cylinder, they can figure out how much water a bottle holds. They can also estimate how many juice bottles would fill a cooler. With spheres, they can imagine the volume of sports balls or even think about how much space a giant bubble takes up. For the volume of cones, they can think of everything from a traffic cone to the swirl of their favorite ice cream! These are all everyday things, but now they can calculate and understand the space inside them.

Volume activities make these connections more concrete. They also help our students appreciate how math answers real questions and solves real problems. When our students see that calculating the volume of these shapes has practical, everyday applications, math becomes more meaningful and enjoyable.

Volume Activities To Learn About Cones, Cylinders, and Spheres

The Volume of Cones, Cylinders, and Spheres Math Wheel provides a section that covers key terms, and sections for teaching how to find the volume of a cylinder, a cone, and a sphere. You can use this math doodle wheel to support students’ note-taking as they learn about these foundational geometry concepts. Each section of the math wheel offers structured guidance. This lets you break down the information in a student-friendly way. With examples built in, your students have a ready reference that ties directly into their practice with these volume activities.

1. Key Terms

Before starting a new concept, it’s important to lay the groundwork by learning important vocabulary. You can start here to ensure your students understand these terms before diving into calculations. By introducing your students to these terms in context, you set them up to confidently tackle the volume activities for cylinders, cones, and spheres.

As you go through this section, it breaks down vocabulary like volume, height, pi, and radius. As you go through the definitions, students can write them out in different colors to distinguish them. The section also uses a cylinder and a circle to help your students identify where the height and radius are on the shapes. As students learn about finding the volume of these shapes they can refer back to this section as needed.

2. Volume of a Cylinder

The second section of the wheel provides a clear definition of a cylinder. It also explains that its volume is found by multiplying the area of the base by the height. Your students have a chance to immediately practice this concept by including the volume formula with two examples.

You can use this section to show how easy calculating the volume of a cylinder can be once they understand that it’s just about finding the base area and the height. Visual examples of real-life objects can make this section more engaging for your students as you work through the examples.

3. Volume of a Cone

Next up we dive into the cone. I love to start by reminding students of the elements that make up this 3D shape. After a quick review, we dive into the formula for finding the volume of a come. The written out formula can look a little intimidating to students so breaking it down step by step on the wheel really helps to build their confidence.

This section also explains the relationship between the volume of a cone and a cylinder. It illustrates that the volume of a cone is one-third that of a cylinder with the same base and height, and there are examples to reinforce this. This part is perfect for a hands-on demonstration! You could show how three cones of a given size fit into a cylinder of the same base and height. Your students will think you are magic as you demonstrate these math principles in real life!

4. Volume of a Sphere

In the last section of the wheel, your students learn the definition of a sphere, which is a perfectly round 3D shape. They also learn the volume formula and see examples that help them apply the formula right away. You can use this section to explain why a sphere’s volume formula differs from that of a cylinder or cone. To reinforce this, you could use everyday objects like a basketball or a globe. This lets your students imagine filling the sphere with small units to picture its volume.

After Completing the Doodle Wheel

Once the notes are completed, students complete the practice problems around the wheel. Then it’s time for some coloring! Coloring is a powerful tool for reinforcing understanding and memory retention. It adds a personal, creative touch that helps your students engage with key concepts like the volume of a cone, cylinder, and sphere on a deeper level. It makes it much more than just a decorative feature.

Coloring is optional, so if time is an issue you do not have to do it during class time. But I would encourage you to add some color elements because there are so many benefits. What’s really neat is that adding color to the wheel is also a way to boost memory retention. Studies show that when students engage with material visually and creatively, it strengthens their recall. By filling each section with colors and patterns or even leaving some areas blank, your students get a hands-on way to interact with math concepts. You can check answers before students start coloring, ensuring that the math remains clear and easy to assess.

Coloring the wheel helps anchor the concepts in your students’ minds. This turns abstract ideas into something concrete. Whether they’re remembering the volume of a cylinder formula or recalling the steps to find the volume of a sphere, this visually engaging tool gives them a memorable way to revisit and retain their understanding.

If you don’t want to complete the coloring in class, there are other options. You can use it as an early-finisher activity or assign it as a calming homework task. This flexibility lets your students focus on understanding the volume activities during structured learning time while offering an extension that connects with them visually.

Benefits of Math Doodle Wheels as Part of Your Volume Activities

There are several great ways math wheels make learning math more effective and enjoyable! One of the best things about math wheels is how they boost engagement. These wheels add a sense of fun to learning, drawing your students in and making math feel a little less intimidating. The circular format, combined with the option for colors and doodles, turns note-taking into something visually appealing. This helps your students understand and remember concepts like volume of shapes such as cones, cylinders, and spheres.

Organization is another key benefit. Math wheels break down complex topics into smaller, manageable sections. This makes concepts easier for your students to grasp. The color and doodles help with visual memory, allowing your students to create mental images they can refer back to whenever they need to. They’re perfect for meeting each student’s unique needs, making learning more personal and impactful. They also work as a reference tool that your students can use all year long, which gives them a ready resource whenever they need a refresher.

I love the versatility of using math wheels in the classroom. They can be used as the foundation of your main lesson or review activity. You can complete the entire wheel at one time or you can break them into multiple parts completing them as you teach each new concept. Use the wheel as guided practice and the practice problems around the wheel as independent practice. You can add color and doodles as you fill in the wheel or after. This versatility really allows you to use the math wheel in a way that best fits your classroom. No matter how you use it, your students will love how it breaks down math into easy to understand steps.

Stick around until the end for some additional resources that are ready to be used in your classroom. They’ll make learning about area an approachable and dare I say fun experience for your students!

Guided Notes Math Wheel for Area of Quadrilaterals and Triangles

Energize your classroom as you learn about quadrilaterals and triangles using the Area Math Wheel!

This dynamic tool is ideal for introducing and instructing the computation of area. It doubles as a fantastic resource for later review within the unit. Whether used for initial learning or as a reinforcement tool, the math wheel ensures an understanding of these important geometric concepts. Serving as both a graphic organizer and a study aid, students can tuck this interactive resource into their notebooks for reference.

Let’s dive into each of the five sections of this math wheel. With this math tool, you can watch as your students embrace the exploration of area with enthusiasm!

Let’s take a look at how I introduce the area of quadrilaterals and triangles before I start explaining the first section of the math wheel! I always like to see what my students already know, so we review what we know about area, quadrilaterals, and triangles. We might also take some time to use graph paper or unit blocks to create squares and rectangles and show how the inside of a shape is composed of square units. This helps make the concept a little more concrete before we jump into formulas.

1. Squares

Once we have refreshed our memories, it’s time to take a look at the first section on our math wheel, which is how to find the area of a square!

Before diving into the example, we write down a few notes to keep in mind. On the left side of this section, I have my students write down that area = side x side. On the right side of the section, we write down another note about how side x side is the same as length x width to find the area of the square. And. . . we can’t tackle the area of a square without remembering that all four sides of a square are the same.

We then turn our attention to the example in the section. One side is labeled 7 m. I have my students write an “s” underneath this measurement to help my students remember side also refers to length or width. Where it says A = ____, we write s² because we need to multiply two sides to find the area of the square, and since both sides are the same length we can write that as s². Underneath, we write out how this formula plays out in our example. I add another equal sign and write = 7² and then on the following line I multiply 7 x 7, which equals 49, and add this as the answer. The area of this square is 49m².

2. Rectangles

Moving to the next section of our guided notes for the area of quadrilaterals and triangles, we turn our focus to rectangles. In this section, I explain the formula to my students for how to find the area of the rectangle.

The first thing we write down is the formula for area, which is area = length x width. Students can shorten that to A = l x w. Looking at our rectangle example, we notice that the shape has two measurements (11 in and 5 in).

We don’t jump right into solving just yet. We first need to identify which is the length and which one is the width. The side with 11 in. is labeled with a “L” for length, and the side with 5 in. is labeled with a “W” for width. When labeling, I use two different colors. Length is in green and width is in purple. I will write the number in the formula with the matching color to help my students see easier where the numbers are coming from.

Now that the sides are labeled, my students are ready to solve! We remind ourselves about the formula, and then we plug in the numbers so it reads A = 11 x 5. This equals 55, so our area for this rectangle is 55 in².

3. Parallelograms

In the third section of our math wheel, I review two new terms, base and height, which are used within the area formula for parallelograms. We talk about how the base is the length of one side, while the height is the perpendicular segment between the base and the opposite side.

The first thing we write down is the formula for finding the area of a parallelogram. Area = base x height is written out along the side of this math wheel section.

Next, we take a look at the parallelogram example. It has two measurements, 12 ft. and 4 ft. I have my students pull out their two different colors once again. We color code our numbers on our parallelogram and also in our equation to solve for area. I take my blue marker, and we label 12 ft. with a b for base. Then I take my orange marker, trace the dotted line, and write a h for height next to 4 ft.

Once we have our labels written down, we are ready to solve the area! Following the formula, A = b x h, we fill in the length of the base and height (12 and 4). When we multiply 12 x 4, we get 48. So, the area of this parallelogram is 48 ft^.2.

4. Trapezoids

It’s Not So Complicated

In the trapezoids section, I give a heads-up to my students that there are more numbers in this formula. We talk about how it looks trickier than the other formulas, but in reality, we are going to break it down into small steps just like the others. Throwing in a fraction throws off students, so I like to add reassurance to ease their nerves.

We start by writing out the formula in words. We look at it and see what’s familiar to us and what is new. Then we write Area = 1/2 height (base₁ + base₂). Together, the class and I point out that we know what height and base mean. We also know that using the order of operations, when there is a number next to a set of parenthesis, we need to solve what’s in the parenthesis before multiplying the inside number by the number on the outside.

Before we begin our trapezoid example, we have our two colors ready to help us see the different parts. Then we find the three measurements on the trapezoid, which are 9 cm, 6 cm, and 11 cm. First things first, we must determine which of these numbers represents the height and which represents the 2 bases. I have students look back at the parallelogram example to make this determination.

Then using the first color, we trace the dotted line and label 6 cm with a “h” for height. Then we pick up our second color and we trace the top line and the bottom line of the trapezoid. We label 9 cm with a b₁ and 11 cm with a b₂.

Applying the Formula to Our Example

Now it is time to plug our numbers into the formula! I remind my students that the formula is A = 1/2h (b₁ + b₂). This becomes A = 1/2 (6) (9 + 11). We begin working through the equation one step at a time. I make sure that after each small step we start a new line. This really helps students see how simple it is to use this formula.

First, we add 9 and 11 to get 20. Our equation now looks like A = 1/2 (6) (20). Next, we find one-half of 6. When 6 is multiplied by 1/2, it becomes 3. Then we multiply 3 and 20, which equals 60. The area of this trapezoid is 60 cm²!

I love that when we finish this example there are lots of smiles and eyes gleaming with confidence. It’s one of those ah-ha moments for students when they realize that just because something looks complicated doesn’t mean that it is.

5. Triangles

In the final section of our area of quadrilaterals and triangles math wheel, we discuss how to find the area of a triangle.

Breaking Down the Formula

To one side in the section, we write out the formula: area = 1/2 x base x height or A = 1/2b x h. Despite this being another “complicated” formula students generally see this one as a fun challenge because they have learned the power of breaking it down into small steps.

I check in with my students to see what they notice and to identify any similarities from previous sections. They’ll point out that there is a fraction involved, we are still using base and height, and how we are now multiplying 1/2 by the base, not by the height.

Once we have analyzed the formula, we turn our attention to our triangle example! We grab our markers, and we take note that there are three measurements on the triangle, even though we only need 2. So the first order of business is identifying the base, the height, and the extra information.

Finding the Area of a Triangle

Taking my green marker, I guide my students in labeling 10 m with a “b” for the base. Then we take our next color, mine is blue, and we trace the line that is cutting down through the middle of the triangle. In the same color, we label 12 m with a “h” for height.

We are ready to plug in our numbers and solve! First, we write out the equation with the numbers: A = 1/2 (10) (12). We put the order of operations into play and know that we are going to do the multiplication from left to right. So we multiply 1/2 and 10 first, which equals 5. Then we multiply the 5 and 12, which equals 60. The area of this triangle is 60 m²!

What’s Next?

Once we complete the math wheel, my students engage in practice problems placed around the math wheel. This allows for either guided or independent practice based on their understanding. My students have the option to add a personal touch by coloring the background pattern or adding doodles that will help them remember the different formulas or steps.

Once finished, these math wheels find a permanent home in my students’ math notebooks. They serve as a valuable point of reference throughout the area of quadrilaterals and triangles unit and beyond. These guided notes help to break down complex concepts into smaller chunks of information. This makes the concept easily accessible through this visual aid.

What Are Math Doodle Wheels?

I’m standing at the front of my class and all I see are blank stares, math nerves, and a whole bunch of “I’d-rather-be-anywhere-else” vibes. My students were going through the motions of note-taking, but it was clear, the info wasn’t sticking. That’s when the lightbulb moment happened, and Math Doodle Wheels were born!

I wanted notes to be more than just a checkmark on the to-do list. I wanted them to be a trusty sidekick, a go-to guide during units and review sessions.

So, I crafted these wheels where math concepts are broken down into bite-size sections of the wheel, vocab gets its VIP definition moment, and each step is practiced with examples. Plus, there’s space for some extra practice. The secret? We’re color-coding and doodling symbols as we go to help them remember the steps and vocabulary. Suddenly, note-taking became an art, and my kiddos enjoyed it and used these notes as tools.

How I Teach Types of Triangles

We’re diving headfirst into the world of triangles, and it all begins right at the heart of our Types of Triangles Math Wheel. I gather my students around, and we start chatting about the six main players in the triangle game – equilateral, scalene, acute, obtuse, right, and isosceles. Now, here’s the math magic. No matter how different these triangles are, their angles always add up to 180°. I have my students write that 180° right in the center of our wheel to be a constant reminder.

With the center complete, I kick off the grand tour of the wheel. The first thing we discuss is that there are two ways we can classify triangles. We can classify them by their sides and we can classify them by their angles. To keep this in mind, we tackle the three types of triangles classified by their sides first, then we move on to the three types of triangles classified by angles. With that explanation, we have now taken 6 types of triangles and grouped them into two groups of three and made them a little easier to understand.

Sections of the Types of Triangles

Equilateral Triangle

I explain that this triangle is known for having three equal sides, which we jot down in that section. I draw three hash marks, one on each leg of the triangle, to show that they are equal.

To give them an example of number measurements, I write 6 meters on all three sides. I like starting with equilateral because it’s the least intimidating since all three sides are the same measurements.

Scalene Triangle

Now, onto the scalene triangle.

I kind of think of it as the rebel of the triangle crew. It’s the complete opposite of our equilateral triangle because it plays by its own rules with no equal sides.

We fill in the blank in our notes section. Then, it’s example time. I draw my trusty triangle and label it with the following measurements: 5 cm on the short leg, 7 cm on the top leg, and 10 cm on the bottom leg. Why? To show my students how each side has its unique length.

Isosceles Triangle

Now, we wrap up our note-taking adventure with the isosceles triangle.

An isosceles triangle is all about the buddy system, boasting two equal sides. In our triangle example, I draw single hash marks on the left and right legs because they’re equal measurements. I label both legs with 4 feet, emphasizing their equal status. Now, I draw two hash marks on the bottom leg, signaling that its measurements are playing solo. I label 6 feet for the bottom leg, driving home the point that it’s not on the equal side with the left and right legs.

Acute Triangle

Next up is the acute triangle. I walk my students through jotting down the key detail that all three angles inside an acute triangle are less than 90°.

I draw two examples to show my students a couple of different scenarios they may encounter. In the first triangle, I sketch a curved line at each corner, representing an angle, and drop 60° in each. We add each of the three angles, each at 60°, sum up to 180°, sealing the deal that triangles have a total of 180° inside.

I draw another triangle to explain that acute triangles won’t always have the same angle measurements. In this second one, I draw those curved lines again and jot down 70°, 60°, and 50° in the corners. Quick adding by my eager students confirms the angles total to 180°.

Obtuse Triangle

In our next section, we dive into the world of the obtuse triangle.

For a triangle to earn the “obtuse” badge, it needs to boast one obtuse angle, meaning one angle must be greater than 90°.

In my example, I draw an obtuse triangle.

I draw the curved line to represent the angle in the top angle inside the triangle and write 120°.

We talk about how we can check that this is obtuse by noting how it’s a number larger than 90.

Right Triangle

We move to the right triangle section.

We review what makes a right angle, which is when a 90° angle is formed at the intersection of two perpendicular lines. I have my students write down that one angle must measure 90°. Then, in the triangle, we practice drawing the square symbol where the two lines intersect to represent 90°.

What’s Next?

Once we wrap up our note-taking session, it’s time to put our knowledge to the test by tackling the examples scattered around the math doodle wheel.

I pre-select a few examples, modeling to my students my thought process and reasonings for classifying which triangles to which measurements. After a couple of examples, I give the steering wheel to my students. They become the teacher and start leading me through the steps for a few examples. Then, I partner them up to complete the remaining practice examples. I set a timer so we have time to check their answers and talk through their reasoning.

After conquering those practice problems, I give my math enthusiasts a little artistic freedom. They go back into their notes, adding splashes of color and extra symbols to etch the differences between the triangles into their memory. It’s a personal touch that not only triggers those “aha” moments but also makes math feel like a comfortable space. The math doodle wheel isn’t about bombarding them with gibberish and 50 problems. It’s all about breaking the skill into bite-sized chunks, creating a handy reference tool that’ll be their math companion throughout the year!

More Resources for Types of Triangles

Once I complete notes with my students, I want them to be applying what they have learned. If you don’t use it, you lose it, right? When I am planning practice activities, I want to make sure they are interactive and allow everyone to have a seat at the table. Math anxiety is real! It’s important to be aware of all the emotions your kiddos may be feeling when it comes to math. With that in mind, I have included some types of triangle activities that have students practicing the skills in a collaborative, low-intensity manner.

Classifying Triangles Footloose Math Task Cards Activity and Math Wheel

An awesome classroom activity I use with my students to review types of triangles and to get them up and moving is my Types of Triangles Footloose cards.

Footloose isn’t just your typical sit-and-listen routine. I hand out these cards, and suddenly, we’re not just classifying triangles by sides and angles.

We take it a step further by finding those missing angles and sides like geometry detectives. Sometimes, alarms go off in my students’ heads when they discover a missing angle.

We pull out our math doodle wheels and remind ourselves that all three angles within a triangle equal the grand number of 180!

I tend to shake up the delivery of the task cards because sometimes I have them posted around the classroom ahead of time. Then they travel around to each card with a partner to solve and record answers on their paper.

With that being said, Footloose isn’t a one-size-fits-all deal. You can roll it out for the whole class, turn your class into an interactive experience, use it in small groups, or throw it into center rotations. It’s flexible, it’s fun, and it’s got the whole class moving!

Triangles Color by Number Activity Missing Angles and Sides

My Triangles Color by Number activity is a low-intensity math activity for different types of angles and missing angles with a dash of color. Students solve problems while turning their answers into masterpieces!

My students tackle 20 problems that dive deep into triangle types. Problems range from finding missing side lengths and angle measures to calculating the perimeter of triangles. Instead of the usual pencil and paper routine, they find their solutions on a coloring sheet/section.

I love using this resource for many reasons, but one of my favorites is that it’s self-checking! If their answer isn’t on the coloring sheet, they know it’s time for a quick math check. It’s instant feedback that we know and love!

Plus, there are both print and digital versions available. I like flexibility, which is the name of the game for us teachers, so I wanted this resource to be flexible for your teaching style.

Classifying Triangles Math Game | Math Activity | Truth or Dare

Truth or Dare? I choose truth! I’ve got a game-changer for your next class or review session for identifying types of triangles that’s as fun as it is educational.

I’ve crafted 36 question cards that’ll turn your class into a buzz of excitement. It’s not your average Q&A session because this one comes with a “truth” or “dare” twist!

I pull this Truth or Dare activity out for center time when I am working with small groups, will be out of the classroom, or for review sessions. My students love it when they see this activity on the schedule.

Your students dive into a world where they get to choose their fate.

Questions focus on the different triangle types (acute, obtuse, right, isosceles, equilateral, scalene) and essential concepts like the 180 degrees in a triangle.

They earn a 1-point “truth” for those classic true or false questions. If they’re feeling daring, there are “dare” cards worth 2 or 3 points, throwing in some challenges. Think along the lines of finding missing angles or sides, explaining why a triangle is classified a certain way, or even determining if a shape can make the triangle cut based on angle measures or side lengths.

The beauty of this is it’s not just a solo gig. Gather your kiddos in groups of 3-4, and let the game begin. Keep in mind the smaller groups mean more questions tackled by each student, meaning more practice!

Process for Exploring Surface Area

• While some groups are able to write a formula that reflects a correct understanding of the concept (though not written correctly “variable-wise”), others often remain stumped.
• Even though they are stumped about writing a formula, the “stumped groups” are usually able to explain to me HOW they found their surface area.
• Most of them explain that they found the area of the front and multiplied by 2 because the back is the same; they found the area of the top and multiplied by 2 because the bottom was the same, and the same idea for the sides; then they added those three sums together.
• Other groups find the area of all six surfaces and add them all.
• Some groups will find the area of the 3 different sides, add them and then multiply by 2. 

Based on our conversations, I know when they have found a correct way to find the surface area (or can then guide them if they are off track – the conversations are so important!). When it comes to writing a formula, some groups get very close, but have to be guided toward naming the length, width, and height with different variables.

Wrapping Up and Moving to Surface Area Notes

Do your 6th grade math students understand the Triangle Inequality Theorem? Do they know what that is?

Mine did not, and although we’re trying to get through quite a bit of material before our state testing, we took some time today to explore triangles and the discuss the triangle inequality theorem.

Maybe you’ve done this exploration already, but it was quick and fun, so I thought I’d share.

​The goal of the activity is to help students discover that not all line segments can meet to form a triangle.

Discovering Triangle Inequality Theorem

Without explaining triangle inequality to my math students,  I gave each group three straws I had cut to different lengths and asked them to use their straws to make a triangle.

• In my first math class, I used straws that were cut to 2 inches, 3 inches, and 5 inches.
• These lengths, using straws, made it almost possible to make a triangle, even though it shouldn’t be possible. So, I had to insist that their straw ends be lined up perfectly. I used 3, 5 and 2 inches to show that even these dimensions won’t make a triangle, because the sum is equal to the longest side, not longer than it.
• After understanding how precise they had to be and that they couldn’t leave segment parts sticking out of the end of the triangle, they came to the conclusion that it couldn’t be done.

Next I gave the groups a new set of straws that were cut to 3 inches, 3 inches, 5 inches. In this case, they were excited to make their triangles in about 30 seconds!

​We then discussed why the 3, 2, 5 didn’t work and worked our way to “creating” the triangle inequality “rule.”
​

Lesson Adjustment

For my next math classes, I trimmed the 3-inch straws to 2 inches, so these classes would have more difficulty getting the ends to meet. It was so funny to hear their comments:

• “This doesn’t work.”
• “Is this a trick question?”
• “This is impossible!”

And then, their excitement when they made the 3, 3, 5 triangle, and their exclamations of  “We did it first,” was great to hear!

Again, we discussed the idea that the sum of the two smaller sides of a triangle must be greater than the longest side.

Students then applied the Triangle Inequality Theorem to their homework.
