Finding Unit Rate in Diagrams

This lesson teaches how to find unit rates in diagrams. It begins with a basic explanation of unit rate, using the example of milk costing $3 per gallon. The lesson then introduces the concept of unit rate as the constant of proportionality. It addresses common student difficulties in identifying unit rates in diagrams and provides practical examples, such as Kevin's pet shop, to illustrate how to find unit rates by looking for single quantities. The lesson concludes with a summary of the key points covered.
