Understanding Proportional Relationships

Mr. Weaver's lesson focuses on understanding and solving problems involving proportional relationships. The lesson covers strategies for identifying proportional relationships, such as creating equations and tables, and calculating constants of proportionality. An example comparing juggling rates is used to illustrate these concepts. The lesson concludes with a discussion on constant rates and their link to proportionality, encouraging students to apply these strategies to determine if two quantities are proportional.
