The purpose of this activity is for students to familiarize themselves with the structure of a recipe and consider the mathematical questions that could be asked about a recipe. When students wonder about what mathematics is involved in a situation, they model with mathematics (MP4). A blackline master of a recipe has been provided. If available, have students use cookbooks or internet enabled devices to look for recipes that interest them.

• Invite previously selected students to share the kinds of information they found in recipes.
• If available display examples of a measuring cup, a teaspoon, and a tablespoon for student reference.
• Invite students to share mathematical questions that could be asked about a recipe.

The purpose of this activity is for students to use what they have learned about multiplying and dividing fractions to solve a problem involving a recipe. Students have to figure out a way to measure the ingredients for a recipe using a limited set of measuring tools. They have to look for relationships between the amounts that need to be measured and the tools that are available. When students model a situation using a representation such as a drawing or equation, they model with mathematics (MP4).

• Invite previously selected students to share how they solved part of the problem.
