Week 7: Introduction to Simple Subtraction
Objectives:
- Pupils will understand the concept of taking away (subtraction).
- Pupils will solve simple subtraction problems using objects and visual aids.
Materials Needed:
- Counting objects (blocks, beads, toys)
- Flashcards with simple subtraction problems (e.g., 2-1, 3-2)
- Visual aids (pictures showing subtraction with objects)
- Number chart (1-10)
Introduction (5 minutes):
- What is Subtraction?
- Explain that subtraction means taking something away.
- Give a simple example: “If I have 3 toys and I give 1 toy to my friend, I have 2 toys left. I took 1 toy away!”
- Show a subtraction flashcard (e.g., 3-1) and explain that it shows how many are left after taking some away.
Lesson Development (15 minutes):
- Hands-on Subtraction:
- Use counting objects like blocks or toys.
- Start with 3 blocks and remove 1 block, asking the children to count how many blocks are left.
- Say, “3 blocks take away 1 block equals 2 blocks!”
- Flashcard Activity:
- Hold up simple subtraction flashcards (e.g., 2-1, 3-2).
- Ask the children to solve the problems using counting objects.
- Encourage them to count out loud as they take objects away.
- Using Visual Aids:
- Show pictures of simple subtraction problems (e.g., pictures of 3 apples with 1 apple crossed out).
- Ask the children to count how many apples are left after 1 apple is taken away.
- Say, “When we take 1 apple away from 3 apples, we have 2 apples left!”

Activities (15 minutes):
- Subtraction Matching Game:
- Provide children with cards showing subtraction problems (e.g., 3-1) and matching cards with the answers (e.g., 2).
- Ask the children to match the subtraction problems with the correct answers.
- Object Counting Subtraction:
- Give children a group of objects (e.g., 5 toys). Ask them to take away a specific number of toys and count how many are left.
- Reinforce the concept of subtraction by saying, “We had 5 toys, and after we took 2 away, we have 3 toys left!”
