# Unit 5: Algebraic Expressions

## Overview

Ever wondered how to teach algebraic expressions in an engaging way to your 6th-grade students?

In this unit plan, students will first learn about identifying parts of an expression. They will then build on this to master combining like terms and the distributive property.

Lastly, students will explore evaluating algebraic expressions, writing algebraic expressions, and prime factorization, all while engaging with real-life applications of the concepts.
