## Distributive Property

#### Activity Overview

Investigate the concept of algebraic distribution of multiplication over addition using numbers.

#### Objectives

• Students will recognize the Distributive Property of Multiplication over Addition: a (b + c) is equivalent to ab + ac and that ab + ac is equivalent to a (b + c).
• Students will evaluate by substituting in an expression.
• Students will apply the Distributive Property of Multiplication over Addition in a new algebraic situation.

#### Vocabulary

• Distributive Property
• Equivalent
• Expression
