Instructor Overview

Students begin the lesson with a critique of their own work on the Self Check using questions and comments from you to reflect on their work. They then critique three examples of student work on the task, each with its own tools for modeling the given relationship between quantities. Finally, they apply what they learned to a closely related problem.

Key Concepts

Students reflect on their work and connect different ways of representing ratio relationships: tape diagrams, double number lines, and ratio tables.

Goals and Learning Objectives

  • Use teacher comments to refine solution strategies for ratio problems.
  • Deepen understanding of ratio relationships.
  • Synthesize and connect strategies for representing and investigating ratio relationships.
  • Critique given student models created to solve ratio problems.
  • Apply deepened understanding of ratio relationships to a new ratio problem.
