## Unit 5: Expressions

▼

### Overview

*This unit builds on the understanding of numerical expressions from earlier grades. You will understand the use of variables in mathematical expressions. We will write expressions that correspond to given situations, evaluate expressions and use expressions and formulas to solve problems. Students will understand that expressions in different forms can be equivalent, and use the properties of operations to rewrite expressions in equivalent forms.*
