Cooking with Fractions: School Cookbook Project

Grade 5Math1 days
This project-based learning experience, "Cooking with Fractions: School Cookbook Project," teaches 5th-grade students the application of fractions in real-world scenarios by focusing on mathematics within a cooking context. Students engage in activities such as organizing a picnic, partaking in a 'Fraction Feast Challenge,' and scaling recipes to explore the concepts of dividing fractions and adjusting ingredients for various serving sizes. The project aims to develop students' skills in fraction understanding, division, and problem-solving, while connecting math to everyday interests such as food preparation. Reflective activities further enhance their learning experience by encouraging them to evaluate their understanding and confidence in applying fractions to cooking.

Inquiry Framework

Question Framework

Driving Question

The overarching question that guides the entire project.How can we create recipes by dividing fractions, and what role do fractions play in cooking to ensure accurate and tasty school cookbook creations?

Essential Questions

Supporting questions that break down major concepts.
  • What is a fraction and how is it used in cooking?
  • How do the operations of division and multiplication relate to fractions?
  • In what ways can we divide fractions to adjust a recipe's ingredients?
  • How can changes in the quantity of ingredients affect the taste and outcome of a recipe?
  • What strategies can be employed to accurately measure and divide ingredients when cooking?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:
  • Understand the concept of fractions and their application in real-world scenarios, specifically in cooking.
  • Develop the ability to divide unit fractions by whole numbers and whole numbers by unit fractions.
  • Gain skills in adjusting recipes to produce desired serving sizes by dividing fractions appropriately.
  • Enhance problem-solving skills by tackling real-life situations involving fractions.
  • Improve mathematical reasoning and calculation accuracy when working with fractions.

Common Core State Standards for Mathematics

CCSS.Math.Content.5.NF.B.7
Primary
Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.Reason: This standard directly aligns with the project's primary focus on dividing fractions in real-world contexts, such as recipe creation.
CCSS.Math.Content.5.NF.B.7a
Secondary
Interpret division of a unit fraction by a non-zero whole number, and compute such quotients.Reason: The project requires students to understand and compute the division of fractions, specifically unit fractions by whole numbers, which aligns with this standard.
CCSS.Math.Content.5.NF.B.7b
Secondary
Interpret division of a whole number by a unit fraction, and compute such quotients.Reason: Students will need to interpret and compute division of whole numbers by unit fractions while adjusting recipes, which is supported by this standard.

Entry Events

Events that will be used to introduce the project to students

Fraction Picnic Planning

Organize a picnic event where students must plan the entire menu for different group sizes. They'll need to divide fractions to adjust the recipe quantities, making the activity relevant to planning real-life events and engaging their interest in event management.

Fraction Feast Challenge

Invite a local chef to demonstrate how fractions play a crucial role in cooking. Students are then challenged to create their own unique dish by adjusting the recipe based on different serving sizes, showcasing their understanding of dividing fractions. This hands-on experience connects math to their everyday love of food and cooking shows.

Portfolio Activities

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.
Activity 1

Fraction Recipe Designers

Students will select a simple recipe and analyze its ingredients to understand how fractions are used in cooking. They'll learn how to break down each ingredient into fractional parts to adjust for serving size changes.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Choose a simple recipe with clear measurements (e.g., pancake recipe).
2. Identify the fractional parts of each ingredient (e.g., 1/2 cup of sugar).
3. Discuss how many servings the original recipe makes and how many servings you need.
4. Determine the necessary adjustments to each ingredient to match the desired serving size by understanding fraction usage.

Final Product

What students will submit as the final product of the activityA breakdown of a chosen recipe into fractional parts ready for adjustment.

Alignment

How this activity aligns with the learning objectives & standardsAligns with CCSS.Math.Content.5.NF.B.7 by applying fractional division to real-world contexts.
Activity 2

Fraction Scale Chefs

Students will practice dividing fractions to adjust recipes, simulating the work of chefs who must cater to different group sizes. They'll solve problems involving the division of a unit fraction by a whole number and a whole number by a unit fraction.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Use the recipe breakdown from the previous activity.
2. Calculate how much of each ingredient is needed when the recipe is scaled up or down (e.g., doubling or halving servings).
3. Convert these adjustments into fractional problems.
4. Solve these problems to understand the correct ingredient quantities needed.

Final Product

What students will submit as the final product of the activityScaled recipe versions for different serving sizes.

Alignment

How this activity aligns with the learning objectives & standardsSupports CCSS.Math.Content.5.NF.B.7a and 5.NF.B.7b by solving division problems with fractions.
Activity 3

Taste Testing and Fraction Review

In this activity, students review and taste test the scaled recipes to understand how fraction adjustments impacted the taste and consistency of the dish.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Prepare the scaled recipes using the adjusted ingredients.
2. Conduct taste tests and document any changes in taste or texture.
3. Discuss as a group how the adjustments affected the final product.
4. Review the math behind the fraction adjustments and any potential mistakes or learning opportunities.

Final Product

What students will submit as the final product of the activityFeedback report on the taste and quality of scaled recipes, with insights into correct vs. incorrect fraction adjustments.

Alignment

How this activity aligns with the learning objectives & standardsEnhances understanding of CCSS.Math.Content.5.NF.B.7 through real-world application and review of fraction division accuracy.
