Objective

By the end of this lesson, you will be able to apply arithmetic skills to solve potion-related problems.

Materials and Prep

• Paper
• Pencil
• Calculator (optional)

No prior knowledge is required for this lesson.

Activities

1. Mixing Potions: Choose two different potion recipes and write down the quantities of each ingredient required. Use your arithmetic skills to determine the total quantity of each ingredient needed if you want to make a larger batch of each potion.

2. Potion Cost Calculation: Imagine you are running a potion shop. Create a price list for different potions based on their ingredients. Use your arithmetic skills to calculate the total cost of different combinations of potions that a customer might purchase.

3. Potion Measurement: Measure the volume of different potions in milliliters. Use your arithmetic skills to compare and order the potions based on their volume.

Second Grade Talking Points

• "Arithmetic is a branch of mathematics that deals with numbers and their operations, like addition, subtraction, multiplication, and division."
• "In potion-making, we often need to add or subtract quantities of ingredients to get the right proportions."
• "We can use arithmetic to calculate the total cost of different potions by adding up the prices of their ingredients."
• "Measuring the volume of potions helps us understand their capacity or how much space they take up."
• "By using arithmetic, we can compare and order potions based on their volume."
