Finding Unit Rates in Proportional Relationships Using Graphs

This lesson teaches how to determine the unit rate of a proportional relationship by examining graphs. It explains the characteristics of proportional relationships, such as a straight line through the origin, and how to identify equivalent rates. The lesson also covers converting rates to unit rates using the multiplicative inverse and provides examples, including calculating unit rates for running speed and piano keys. The importance of understanding unit rates and their application in real-world scenarios is emphasized.

What common misunderstanding do students have regarding simplified rates and unit rates?

In the example of Dorothy running, how did we determine the unit rate of miles per hour?

How do you find the unit rate of white keys per black key on a piano?
