This lesson is optional. In this lesson, students apply proportional reasoning to calculate nutritional values per one serving of a recipe. The second activity asks students to invent another recipe that meets nutritional requirements to be considered low calorie, low fat, or low sodium. Students likely need to perform various multi-step unit conversions to solve each problem. This context provides students with an opportunity to make sense of problems and persevere in solving them (MP1).
As with all lessons in this unit, all related standards have been addressed in prior units. This lesson provides an optional opportunity to go deeper and to make connections between domains. This lesson can be used as an introduction to the context of students planning their own restaurant, which continues through the next few lessons. However, it is also possible to use other lessons about this context without using this lesson as the introduction.
- Create a recipe that meets the requirements to be considered low calorie, low fat, or low sodium, and justify (orally) the reasoning.
- Determine whether one serving of a recipe meets the requirements to be considered low calorie, low fat, or low sodium, and explain (orally) the reasoning.
- Use proportional reasoning to calculate nutritional values of one serving of a recipe.
Let’s choose some recipes for a restaurant.
Students will need access to a variety of recipes to choose from for this lesson. You can tell students ahead of time to bring in two of their favorite recipes, or have a variety of recipe pages for students to look through, or give students time at the beginning of the lesson to use an internet-enable device to search online for recipes.
