Objective

By the end of this lesson, you will be able to apply arithmetic skills to sewing by measuring and cutting fabric accurately.

Materials and Prep

Materials needed: fabric, ruler, scissors, sewing machine (optional)

Prior knowledge: basic understanding of addition and subtraction

Activities

1. Measuring Fabric: Practice measuring and cutting fabric using a ruler. Calculate the length and width needed for a simple sewing project.

2. Adding and Subtracting: Create a fun game where you add and subtract measurements to solve sewing-related math problems.

3. Sewing Math Quiz: Design a quiz that involves measuring and calculating fabric dimensions for different sewing projects.

Third Grade Talking Points

• "When we measure fabric, we use numbers to find out how long and wide it is. This helps us cut the right size for our sewing project."
• "Adding and subtracting can help us figure out how much fabric we need for our project. We can add the length and width, and subtract the fabric we already used."
• "Did you know that math is important in sewing? It helps us make sure our clothes and crafts turn out just the way we want them to!"
