## How to Evaluate An Algebraic Expression

What exactly does it mean to evaluate an expression? Once students enter year 7, they begin to recognise that values can be substituted for letters that are present in an expression. After swapping the variable with the number, students then use the order of operations to determine an answer. Students first begin to evaluate expressions with single variables and then move on to using multiple variables.

Teach Starter has created a fun mystery picture worksheet that your students can complete as they learn how to work with variables. After solving all of the problems, students will colour the grid according to the colour guide to reveal a mystery image.

## Tips for Differentiation + Scaffolding

For students that need an additional challenge, consider using the editable version and include negative values or decimal amounts.

If there are students that require additional support, students can use a multiplication chart to help with basic problems. Additionally, you could limit the number of problems a student must solve and provide the answers to some of the questions to lessen the workload.

Because this resource includes an answer sheet, we recommend you print one copy of the entire file. Then, make photocopies of the blank worksheet for students to complete.
