Activities to Teach Students to Multiply Fractions and Mixed Numbers by Whole Numbers in Recipes

Cooking is not just about creating delicious food items, but it is also a great way to teach math skills to students. Specifically, working with recipes can help students practice multiplying fractions and mixed numbers by whole numbers. By participating in cooking activities, students can see the real-world applications of mathematical concepts and how it is used in everyday life.

Here are some activities that can be done in the classroom setting to teach students how to multiply fractions and mixed numbers by whole numbers while using recipes:

1. Recipe Analysis

Provide students with copies of a recipe and ask them to thoroughly analyze it. Students can identify the various ingredients, tools and measurements needed in the recipe. They can also convert the recipe according to the number of servings required. To take it further, ask students to multiply the recipe’s proportional values by specific whole numbers. This activity helps students to understand the proportionality of ingredients and how they can be increased or decreased based on the requirement.

2. Scaling a Recipe

For this activity, students can work in groups. Ask each group to bring a favorite recipe to class that is big enough to serve 10 people. Then, have the students reduce or increase the recipe proportionally, to create a new recipe with half or twice the original serving size. Here again, students can practice multiplying fractions and mixed numbers by whole numbers as they adjust the measurements for individual ingredients required for the new recipe. The activity also showcases team building and collaboration skills.

3. Fraction and Whole Number Matching Game

In this game, students are given a variety of fractional amounts and whole numbers, and they have to match them together to form a complete recipe. For example, if the recipe requires 1/4 of a cup of flour for every 2 servings, students would need to match 1/4 with 2 to form the recipe’s total ingredients. This activity helps students revise their multiplication skills, as well as identify the right quantities that can be put into a recipe to achieve the desired outcome.

4. Measuring Ingredients

This activity allows students to work with the ingredients first hand. Provide students with a recipe to make muffins. Students can multiply the recipe’s measurements by whole numbers to increase the number of muffins they make. The activity helps them understand the importance of measuring ingredients accurately and how multiplication of fractional and whole numbers can affect the final outcome of the recipe.

5. Recipe Competition

To add an element of competition and fun to the recipe-based activities, host a recipe competition among the students. Divide the class into groups; each group can come up with a unique recipe for a dish and prepare it in class accordingly. The recipe should include multiplication of fractional and whole numbers to increase or decrease the ingredient ratios. In this way, students can practice the concept and apply it in a creative manner. The winner can be selected based on ingredients chosen, taste and presentation of the dish.

In conclusion, cooking is a hands-on, enjoyable and practical way to teach mathematical concepts to students. By using recipes, students can practice multiplication of fractions and mixed numbers by whole numbers, and hone their skills in preparation for the real world. The activities mentioned above enable students to have fun while learning and reinforce the idea of mathematics being a critical life skill.
