**Simple but Challenging Activity for the First Day of Math Class - and Any Day After!!**

**First Day of Math Class**

The first day of math class is an exciting time! Getting to know the new students, giving them an opportunity to get to know each other…a new beginning together:-)
For several years now, I have used this pentomino activity on the first day of math class in 6th grade math. (Most of the teachers who have used this activity are teaching 5th – 8th grades.)

I’ve written a few posts about it (on my old blog), because each year I find more benefits to using the activity.

It’s a seemingly simple activity, and when I first explain it, students think it’ll be a piece of cake. BUT, they find it to be quite challenging.

And I find it to be an excellent way for students to start working cooperatively on the very first day of the math year!

**How This Pentomino Math Activity Works**

Students work in small groups of 3 or 4 to create a rectangle using all 12 of the pentominoes. This rectangle should fit in the given frame.

That’s it – make a rectangle, with** no gaps or overlaps and with no pieces going outside the frame**.

As I said, it sounds pretty simple, but if you’ve attempted it yourself, you know that it’s not as easy as it sounds.

It takes the groups quite a while to complete this math activity…and honestly, some *never* finish if I don’t give some hints.

It’s great that it takes so long, because students are *really* thinking, talking to each other, sharing ideas, speaking their thought processes, working together, and being persistent. In the years that I’ve been doing this, I think I had one student who wasn’t really engaged.

This is the type of activity that allows all students to persevere, regardless of their background knowledge in math. All students can manipulate the pentomino pieces and offer suggestions; and while some students are strong in certain areas of math, others are stronger spatially. This math activity allows them all to have success.

**What Math Teachers Can Learn/Observe Through This
Activity**

While this activity is a great first day of math class experience for the students, it’s also great for me!

It gives me the opportunity to observe my new students and start learning about them immediately on the first day of class. I learn things like:

- How they approach tasks
- How they interact with others
- Who will try to take charge
- Who will sit back and watch/listen

It’s a fantastic learning time for me!

**Pentomino Math Activity Materials**

In my classroom, I only had 12 x 5 inch frames for the pentomino activity, which I inherited from someone along the way.

I decided, though, that I wanted to make frames with different dimensions (10 by 6 and 15 by 4), so I made those on the computer (on 8.5 x 11 pages).

So that the pentominoes would fit into these frames, I had to make the pentominoes smaller. So, now I have 3 different sizes of pentominoes.

Having the different sizes and different frames allows me to give groups slightly different tasks, if I choose.

It also provides a new set for students to try if they complete the initial challenge and want to start another.

These pentomino sets are also excellent for fast finishers, indoor recess, or study hall time…my students were always asking if they could use them because they had never figured out the initial challenge and they really wanted to figure it out!
