## Lesson: Rates

Developing the Concept

Now that students know how to find a unit rate, they will learn how to find an equivalent ratio using unit rates. Finding equivalent ratios is similar to finding equivalent fractions.

**Wrap-Up and Assessment Hints**

Rates are basic to students' use of mathematics in everyday life. You can ensure that students understand the concept and can apply their understanding to real-world situations, such as figuring the unit cost of items packaged in multiples, calculating comparable cost of different quantities, and comparing rates of speed measured in different units. Provide ample practice for students to express rates as ratios of different units and make comparisons between them.
