Objective

By the end of this lesson, you will be able to apply arithmetic concepts to solve mathematical problems while incorporating your interest in cosplay.

Materials and Prep

• Paper and pencil
• Calculator (optional)
• Basic knowledge of arithmetic operations (addition, subtraction, multiplication, and division)

Activities

1. Activity 1: Cosplay Shopping

   Imagine you are planning to cosplay as your favorite character and need to buy different costume pieces. Create a budget for your cosplay and list the prices of the items you want to purchase. Use addition and subtraction to calculate the total cost of your cosplay outfit.

2. Activity 2: Cosplay Measurements

   Measure your body dimensions (height, waist, chest, etc.) and convert the measurements to different units (inches, centimeters, etc.). Use multiplication and division to convert the measurements accurately.

3. Activity 3: Cosplay Group

   Imagine you are part of a cosplay group. Divide the total budget for the group's costumes equally among the members. Use division to determine how much each member should contribute or how much each member will receive if the budget is already set.
