Instructor Overview

Students are asked to fix a botched mixture that does not follow a given recipe. To fix the mixture, students must find a ratio of eggs to flour that is equivalent to 2:3, but without explicit instruction on the concept of equivalent ratios.

Key Concepts

Students are invited to investigate the underlying idea of equivalent ratios by “correcting” the ratio between two ingredients in a botched mixture that does not follow a given recipe.

Goals and Learning Objectives

  • Explore a problem based on a recipe with two ingredients.
  • Share approaches, clarify reasoning, and develop clear explanations of how to know a mixture has the right balance of ingredients.
