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.
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.
