Objective
By the end of this lesson, the student will be able to apply arithmetic skills in a cooking context, such as measuring ingredients, understanding fractions, and calculating cooking times.
Materials and Prep
- Measuring cups and spoons
- A recipe that involves measurements and fractions
- A kitchen scale (optional)
- Paper and pencil for calculations
Prior knowledge: Basic understanding of addition, subtraction, and fractions.
Activities
-
Choose a simple recipe together, such as chocolate chip cookies or pancakes.
Discuss the importance of measuring ingredients accurately in cooking.
Ask the student to read the recipe and identify the measurements needed.
Have the student measure the ingredients using the appropriate measuring cups and spoons.
Encourage the student to use mental math or written calculations to adjust the recipe for more or fewer servings.
-
Introduce the concept of fractions in cooking.
Show the student examples of fractions commonly used in recipes, such as 1/2 cup or 1/4 teaspoon.
Have the student practice measuring and identifying fractions using different ingredients.
Discuss how to add or subtract fractions when adjusting a recipe.
-
Explain the concept of cooking time and temperature.
Show the student a recipe that includes baking or cooking instructions.
Discuss how to convert between different units of time, such as minutes to hours or hours to minutes.
Ask the student to calculate the total cooking time using the given instructions.
Third Grade Talking Points
- "In cooking, it's important to measure ingredients accurately so that our recipes turn out delicious."
- "Fractions are used in cooking to represent portions of ingredients. For example, 1/2 cup of flour means half of a cup."
- "We can adjust recipes for more or fewer servings by using math. We can add or subtract the amounts of ingredients."
- "Cooking time and temperature are important for making sure our food is cooked properly. We need to follow the instructions in the recipe."
- "We can convert between different units of time, like minutes and hours, to understand how long something needs to cook."
