# Lesson Plan: Writing and Evaluating Algebraic Expressions Mathematics • 7th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to write algebraic expressions and evaluate them for specific values of their variables.

#### Objectives

Students will be able to

• write an algebraic expression, using one or more basic operations, to represent
• a geometric situation,
• a word problem,
• identify when two algebraic expressions are equivalent,
• write an algebraic expression and evaluate it for a specific value of the variable,
• solve more complex problems, such as writing and evaluating an algebraic expression involving more than one variable or writing an algebraic expression for the area of a simple shape when given the perimeter.

#### Prerequisites

Students should already be familiar with

• reading and writing basic algebraic expressions without simplifications,
• simplifying algebraic expressions by combining like terms,
• using the four basic operations on positive and negative numbers.

#### Exclusions

Students will not cover

• writing and evaluating formulas,
• the product rule for exponents.
