Class Cookbook: Scaling Recipes

Grade 4Math2 days
In this project, 4th-grade students create a class cookbook by scaling recipes using addition and subtraction. They explore how to adjust recipes to serve different numbers of people, understanding the real-world applications of math in cooking. Students collaborate to reconstruct recipes, scale them up and down, and compile them into a community cookbook, emphasizing accuracy and clear instructions. The project integrates math skills with culinary arts, fostering teamwork and problem-solving.

Inquiry Framework

Question Framework

Driving Question

The overarching question that guides the entire project.How can our class create a cookbook with recipes scaled to feed different groups in our community, using addition and subtraction to ensure accurate measurements and delicious results?

Essential Questions

Supporting questions that break down major concepts.
  • How can we adjust recipes to serve different numbers of people?
  • How does scaling a recipe involve addition and subtraction?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:
  • Students will be able to accurately add and subtract multi-digit whole numbers to adjust recipe ingredient amounts.
  • Students will understand the real-world application of math in cooking and meal preparation.
  • Students will be able to collaborate with classmates to create a class cookbook.

Common Core Standards

4.NBT.B.4
Primary
Fluently add and subtract multi-digit whole numbers using the standard algorithm.Reason: Directly addresses the math skill of fluently adding and subtracting multi-digit whole numbers.

Entry Events

Events that will be used to introduce the project to students

Mystery Recipe Challenge

A famous chef's recipe is locked! Students receive clues involving multi-digit addition and subtraction to unlock ingredients and discover the dish. This ignites curiosity and connects math skills to real-world cooking.

Culinary Calamity

A local bakery faces a crisis when their recipe measurements are all mixed up. Students become culinary detectives, using addition and subtraction to restore the recipes and save the bakery. This turns learning into an urgent, relatable mission.

Recipe Remix Challenge

Students receive incomplete recipes and must use addition and subtraction to complete them, adding their creative twists. This fosters culinary imagination while solidifying math skills.

Portfolio Activities

Portfolio Activities

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

Recipe Reconstruction

Students begin by deconstructing existing recipes to understand the role of each ingredient. They will identify the quantities of ingredients and explore how these quantities contribute to the final product.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Select a simple recipe (e.g., cookies, lemonade) with 5-7 ingredients.
2. List all ingredients and their exact measurements.
3. Explain the purpose of each ingredient in the recipe (e.g., flour provides structure, sugar adds sweetness).

Final Product

What students will submit as the final product of the activityA detailed ingredient list with measurements and descriptions of each ingredient's role.

Alignment

How this activity aligns with the learning objectives & standardsEstablishes a foundational understanding of recipe components, preparing students to manipulate quantities later on, aligning with the standard of understanding numbers and their relationships in the context of recipes.
Activity 2

Scaling Sides - Addition Adventures

Students practice scaling recipes up by adding quantities. They will focus on adjusting recipes to serve larger groups, using multi-digit addition to calculate the new amounts of each ingredient.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Choose a recipe from the 'Recipe Reconstruction' activity.
2. Decide on a new serving size (e.g., double the recipe, increase it by 50%).
3. Calculate the new quantity for each ingredient by adding the original amount to itself (or a fraction of itself).
4. Record the original and scaled ingredient lists side-by-side.

Final Product

What students will submit as the final product of the activityA comparison chart showing the original recipe and the scaled-up version, with all calculations clearly displayed.

Alignment

How this activity aligns with the learning objectives & standardsDirectly addresses the standard by requiring students to fluently add multi-digit whole numbers to adjust ingredient amounts.
Activity 3

Subtraction Solutions: Cutting Down Portions

Students practice scaling recipes down by subtracting quantities. They will focus on reducing recipes to serve smaller groups, using multi-digit subtraction to calculate the new amounts of each ingredient.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Select a recipe from the 'Recipe Reconstruction' activity or the 'Scaling Sides - Addition Adventures' activity.
2. Decide on a new, smaller serving size (e.g., halve the recipe, reduce it by 25%).
3. Calculate the new quantity for each ingredient by subtracting from the original amount (or a fraction of the original amount).
4. Record the original and scaled-down ingredient lists side-by-side.

Final Product

What students will submit as the final product of the activityA comparison chart showing the original recipe and the scaled-down version, with all calculations clearly displayed.

Alignment

How this activity aligns with the learning objectives & standardsDirectly addresses the standard by requiring students to fluently subtract multi-digit whole numbers to adjust ingredient amounts.
Activity 4

Community Cookbook Collaboration

Students collaborate to compile their scaled recipes into a class cookbook. They will review each other's work, ensuring accuracy in calculations and clarity in instructions.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Divide the class into small groups.
2. Each group selects a few of their scaled recipes to contribute to the cookbook.
3. Groups review each other's recipes, checking for accurate calculations and clear instructions.
4. Compile all reviewed recipes into a class cookbook, including a table of contents and an introduction.

Final Product

What students will submit as the final product of the activityA class cookbook featuring scaled recipes, complete with accurate ingredient amounts, clear instructions, and collaborative contributions from all students.

Alignment

How this activity aligns with the learning objectives & standardsReinforces the standard by requiring students to apply their addition and subtraction skills in a collaborative, real-world context. It also encourages peer review and attention to detail.
