Objective

By the end of this lesson, you will be able to add and subtract numbers up to 20 using fun and interactive activities.

Materials and Prep

Materials needed:
- Counting objects (e.g., buttons, beads, or small toys)
- Paper
- Pencil
- Crayons or markers
Prep:
- Familiarize yourself with numbers up to 20
- Gather the counting objects and paper
- Sharpen the pencil and get ready to have fun with math!

Activities

1. Counting Fun: Use the counting objects to practice counting up to 20. Create groups of objects and count them together.
2. Addition Adventure: Draw simple pictures and use them to practice addition. For example, draw 5 apples and 3 bananas, then ask how many fruits there are in total.
3. Subtraction Story: Create a simple story where some objects disappear, then ask the student to subtract the number of missing objects from the total. For example, "There were 10 birds in the tree, but 3 flew away. How many birds are left?"
