When your students first start translating algebraic expressions from tables, it can sometimes feel like they’re solving a mystery. They need to find the pattern and figure out how the numbers are related. Then, they need to figure out the relationship using a variable and operation. It’s natural for them to feel a bit overwhelmed. If you’re getting ready to teach this important skill in 6th grade math, I’ve got a simple way to help your students approach it step-by-step with confidence.

In this video, I explain how to help your students organize their guess and check work. We chat about how to find consistent patterns and avoid common mistakes. It’s perfect for new 6th grade teachers or anyone looking to simplify this sometimes tricky skill.
Key Concepts to Focus on With Translating Algebraic Expressions
When teaching translating algebraic expressions from tables, it’s important to start simple. Encourage your students to test basic operations first, such as addition, subtraction, multiplication, or division, before trying a combination of operations. Once they begin working, emphasize the importance of organizing their guesses in an orderly way. Rather than guessing randomly, your students should test operations by trying multiplication by 2, 3, 4, and so on. This approach helps prevent confusion and leads to quicker success.
It’s also important to remind your students that finding a rule that works for just one row isn’t enough. They must check that the same rule applies to every pair in the table. Another point to highlight is the direction of the tables. Some tables are organized vertically, while others are horizontal. Your students need to read carefully to determine whether they are moving left to right or top to bottom when identifying patterns.
For example, if your students are working with a table showing hours and minutes, they need to recognize that multiplying the number of hours by 60 gives the number of minutes. If two hours are equal to 120 minutes, they can identify that the relationship is 2 × 60 = 120 and apply that pattern to the rest of the data. And. . . remind them to read any labels on the table, too! Sometimes the labels help them identify the pattern, like in this hours and minutes example.
Classroom Tips for Translating Algebraic Expressions
One helpful strategy when teaching translating algebraic expressions is to have your students write small mini equations for each data pair as they work through the table. For instance, if the table shows 3 paired with 21, 4 paired with 28, and 5 paired with 35, your students should write out the matching equations like 3 × 7 = 21, 4 × 7 = 28, and 5 × 7 = 35. This approach helps them see the relationship between the numbers and leads them to the correct expression, 7x.
It’s also a good idea to model reverse checking once students find a possible expression. Encourage them to plug each x-value back into the expression. Then, they can verify it produces the correct results across the entire table. Taking this extra step helps catch errors early and strengthens their confidence in their final answer.
Additional Resources
If you’re looking for materials to reinforce translating algebraic expressions, the Translating Between Tables and Expressions Notes and Practice is a great resource to add to your lesson plans. I designed it to give your students a clear, step-by-step approach to finding patterns and writing expressions from data tables.
Inside, you’ll find a full guided lesson page that introduces how to spot operations and relationships. It has built-in tips to help your students organize their thinking. The resource also includes six practice tables for guided work. There are two additional “You Try It” tables for independent practice. A follow-up practice page with eight more problems is also included. To check for understanding, two exit tickets are available in both printable and Google Forms versions. Plus, you’ll have complete teacher answer keys and a Google Slides version to make digital assignments easy to manage.
