Purpose

The purpose of this learning experience is to enable students to apply mathematical concepts of multiplying mixed numbers to practical, real-world contexts through engaging culinary activities. By working with recipes and collaborating with a professional chef, students will discover patterns and strategies that simplify and enhance their understanding of multiplication as a form of scaling. This hands-on project encourages collaboration, critical thinking, and reflection, allowing students to develop confidence in using math beyond the classroom while connecting with their community through a shared appreciation of food.

Learning goals

Through this project-based learning experience, students will develop the ability to accurately multiply mixed numbers and recognize patterns in mathematical operations. They will actively engage in applying these skills to real-world scenarios by scaling recipes, thereby reinforcing their understanding of multiplication as scaling and interpreting it in practical settings. Additionally, students will enhance their communication skills by articulating their mathematical reasoning and collaborating with peers and community members.

Standards
  • [New York] M.EE.5.NBT.5 - Multiply whole numbers up to 5 × 5.
  • [New York] NY-5.NF.5 - Interpret multiplication as scaling (resizing).
  • [New York] NY-5.NF.6 - Solve real world problems involving multiplication of fractions and mixed numbers.

Products

Throughout this lesson, students will create a digital video series documenting their experience with culinary math, featuring personal narration and recipe transformations. They will also develop a presentation board detailing the step-by-step process of multiplying mixed numbers to scale recipes. Students’ understanding and creativity will culminate in a 'math dinner party' and 'Cooking Math Fair,' where they present their scaled culinary creations to classmates, community partners, and family, demonstrating their mathematical journey from start to finish.

Launch

Begin 'Math in the Kitchen: Discovery Day' with a series of interactive cooking stations guided by a local chef. Students will rotate through each station, practicing the multiplication of mixed numbers by creating simple recipes. This hands-on experience will allow students to immediately apply mathematical concepts in a tangible way, setting a foundation for deeper exploration throughout the project.

Exhibition

Organize a 'Cooking Math Fair' where students present their understanding of multiplying mixed numbers through interactive cooking demonstrations. Each group can serve the scaled recipes they've prepared to visitors, including community partners, chefs, and family members. Encourage students to explain the mathematical concepts and patterns they applied in scaling their recipes, showcasing their video series and presentation boards for added context. This engaging exhibition allows students to celebrate their learning journey and model their real-world application of math in the kitchen.
