D: PERFORMANCE OBJECTIVES
By the end of the lesson, pupils should be able to:
- Explain multiplication as repeated addition.

- Form equal groups of objects.
- Change repeated addition into multiplication.
- Solve simple multiplication problems.
E: CONTENT
Meaning of Multiplication
Multiplication means adding the same number again and again.
The multiplication sign is:
×
Multiplication as Repeated Addition
Example:
🍎🍎 + 🍎🍎 + 🍎🍎
There are 3 groups of 2 apples.
Repeated addition:
2 + 2 + 2 = 6
Multiplication:
3 × 2 = 6
More Examples
4 + 4 = 8
This means:
2 × 4 = 8
3 + 3 + 3 = 9
This means:
3 × 3 = 9
5 + 5 + 5 + 5 = 20
This means:
4 × 5 = 20
Equal Groups
●● ●● ●●
There are 3 groups of 2.
So:
3 × 2 = 6
