Unit Description

In this unit, you will learn about equations and inequalities. You will start by identifying a counterfeit coin by using a balance scale and learning how to write the equations or inequalities that represent the scale. You will then continue to use the balance scale to investigate the addition property of equality and to reason about the multiplication property of equality. These two properties will help you solve problems related to real-world situations, such as finding the cost of a pizza and the minimum height required to ride a roller coaster.
