Instructor Overview

Review the multiplication property of equality. Demonstrate the use of “ask myself” questions to understand a problem before solving it. Have students discuss the strategies that they can use when they feel stuck on a problem. Direct partners to solve a problem using a ratio table and equations, and then justify their solution in a presentation using the multiplication property of equality. Have each student write a Summary of the Mathematics in the lesson and work together to create a classroom summary.

Key Concepts

Students use the multiplication property of equality to justify their solution to a ratio problem.

Goals and Learning Objectives

  • Before starting to work on a problem, make sense of the problem by using “ask myself” questions.
  • Persevere in solving a problem even when feeling stuck.
  • Solve a ratio problem using two different strategies.
  • Link arithmetic and algebraic methods to solve a ratio problem.
  • Use the multiplication property of equality to solve ratio problems
