Why this matters
Multiplication helps you understand how your pocket money grows over time. When you save the same amount each week, you can use multiplication to quickly work out how much you have saved. This is useful for planning, saving up for something special, and understanding how money works. It also helps you get ready for bigger maths like times tables and money problems.How it works
Multiplication is like adding the same number over and over again. If you get £2 each week, and you save it for 3 weeks, you can add:- Week 1: £2
- Week 2: £2
- Week 3: £2
Examples you can see
Let’s imagine you get £5 pocket money each week. Here are some examples of how your money grows:| Weeks | Money each week | Total money | How we write it |
|---|---|---|---|
| 1 week | £5 | £5 | 5 × 1 = 5 |
| 2 weeks | £5 | £10 | 5 × 2 = 10 |
| 3 weeks | £5 | £15 | 5 × 3 = 15 |
| 4 weeks | £5 | £20 | 5 × 4 = 20 |

Common mistakes

Fix: Count the number of weeks and add that many times. - Mistake: Mixing up the multiplication and the answer. For example, thinking 5 × 3 = 8 instead of 15.
Fix: Use repeated addition to check your multiplication. 5 + 5 + 5 = 15. - Mistake: Forgetting to write the units (like £).
Fix: Always write the money symbol and the number together.
