# Unit 2: Expressions

## Overview

Ever wondered how to teach expressions and algebraic operations to 7th-grade students in an engaging way? In this unit plan, students will first learn how to write algebraic expressions using key words, then move on to evaluating expressions with rational coefficients and combining like terms. Lastly, they will explore the distributive property with rational coefficients to simplify expressions.

Each lesson in the unit plan guides students through artistic and interactive guided notes, checks for understanding, and concludes with a real-life example that demonstrates the application of expressions in practical scenarios. This approach ensures that students not only understand the mathematical concepts but also see how they relate to the world around them.

It's an exciting way to teach expressions while comprehensively meeting 7th-grade Common Core Standards on algebraic expressions and operations.
