## Lesson: Percents

Introducing the Concept

Reacquaint students with some physical models for percents, such as a 10 x 10 square grid, a meterstick, and money. Spending some time making sure your students understand the relationships among fractions, decimals, and percents is well worth the effort. Having students remember certain relationships between specific fractions, decimals, and percents is also very helpful (for example, = 0.25 = 25%).

**Prerequisite Skills:** Students should know how to use inverse operations to solve multiplication equations. They should also know that the word *percent* means “divide by 100” and is a synonym for the word *hundredths.*
