Recipes and Fractions
10 min
Narrative
The purpose of this Warm-up is to elicit ideas about baking, which will be useful when students solve a problem about a recipe in a later activity. While students may notice and wonder many things about the image, baked goods with which students are familiar and details about the process of how those baked goods are made are the important discussion points.
Launch
- Groups of 2
- Display the image.
- “What do you notice? What do you wonder?”
- 1 minute: quiet think time
Teacher Instructions
- “Discuss your thinking with your partner.”
- 1 minute: partner discussion
- Share and record responses.
Student Task
What do you notice? What do you wonder?
Sample Response
Students may notice:
- There are cracked eggs.
- There’s a measuring cup.
- The person looks like they are baking something.
- There’s flour all over the table.
Students may wonder:
- What are they making?
- How much does the measuring cup hold?
- Is the container shaped like a rectangular prism for measuring?
Activity Synthesis (Teacher Notes)
- “This image is of a baker making a pie crust. What types of baked goods do you enjoy in your community, or with your family?”
- “What do you know about how those baked goods are made?” (The ingredients have to be measured for them to come out right. You follow a recipe to make it.)

- 5.NF.6·Solve real world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem.
- 5.NF.7.c·Solve real world problems involving division of unit fractions by non-zero whole numbers and division of whole numbers by unit fractions, e.g., by using visual fraction models and equations to represent the problem. <em>For example, how much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 1/3-cup servings are in 2 cups of raisins?</em>
