Objective

By the end of this lesson, you will be able to apply arithmetic skills to baking activities, such as measuring ingredients and adjusting recipe quantities.

Materials and Prep

• Measuring cups and spoons
• A mixing bowl
• An oven
• A recipe for a simple baked good (e.g., cookies)
• Paper and pencil for calculations

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

Activities

1. Read through the recipe and identify the measurements needed for each ingredient.

   For example, if the recipe calls for 2 cups of flour and you want to make half the amount, how much flour would you need?

2. Practice measuring ingredients using the measuring cups and spoons.

   Ask yourself questions like, "If the recipe calls for 1/4 cup of sugar and I want to make double the amount, how much sugar should I use?"

3. Calculate the total time needed for baking by adding up the baking time for each batch of your baked good.

   For example, if each batch takes 15 minutes to bake and you want to make 3 batches, how long will it take in total?

4. Experiment with adjusting the recipe quantities to make more or less of the baked good.

   For instance, if the recipe makes 12 cookies and you want to make 24 cookies, how much of each ingredient would you need?

Third Grade Talking Points
