Instructor Overview
Students watch a video showing three different ways to solve a problem involving a proportional relationship, and then they use each method to solve a similar problem. Students describe each approach, including the mathematical terms associated with each.
Key Concepts
Three methods for solving problems involving proportional relationships include:
 Setting up a proportion and solving for the missing value
 Finding the unit rate and multiplying
 Writing and solving a formula using the constant of proportionality
Goals and Learning Objectives
 Solve a problem involving a proportional relationship in three different ways: set up a proportion and solve for a missing value, use a unit rate, and use the constant of proportionality to write and solve a formula.
