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.
