Visualizing Integers

Updated on 08/05/2019

#### Activity Overview

Understand the additive inverse property through simple integer equalities.

#### Objectives

• Students will identify expressions that balance an equation.
• Students will find values that satisfy integer equalities.
• Students will recognize and use the additive inverse property.

#### Vocabulary

• Equation
• Additive inverse property

#### About the Lesson

The Visualizing Integers activity is intended to develop student understanding of the additive inverse property through simple integer equalities. Students will move integer algebra tiles on a balance-scale and observe the changes in the balance-scale. Students will also observe changes in the total numerical value of each side of the equation and how those changes affect the balance.
