Objective

By the end of this lesson, you will be able to apply arithmetic skills to solve measurement and conversion problems while exploring the world of cooking.

Materials and Prep

• Measuring cups and spoons
• A recipe book or printed recipes
• A calculator (optional)
• Paper and pencils

Before starting the lesson, make sure you have a basic understanding of addition, subtraction, multiplication, and division.

Activities

1. Activity 1: Recipe Measurement

   Choose a simple recipe from your recipe book or online. Read through the ingredients and their measurements.

   Using your measuring cups and spoons, practice measuring out the ingredients. For example, if the recipe calls for 1/2 cup of flour, measure out 1/2 cup of flour using your measuring cup.

   Discuss with your parent or guardian how you can use addition or subtraction to adjust the recipe if you want to make more or less of it.

2. Activity 2: Cooking Conversion

   Choose a recipe that requires converting units of measurement. For example, if the recipe calls for 2 cups of milk, discuss how many ounces that would be.

   Using your calculator or mental math, convert the given measurement into a different unit. Practice converting between cups, ounces, pounds, and teaspoons.
