- Making Change (Year 4)
Worked Example
Merchant Marina says:
Merchant Marina sells 4 gems at 45p each. How much total?
- 4 x 45p = 180p.
- Convert: 180p = £1.80.
Answer: £1.80
Common Mistakes
- Multiplying pounds and pence separately and joining them without carrying (e.g. 3 × £2.45: doing 3 × 2 = 6 and 3 × 45 = 135, then writing £6.135)
Convert to pence first: £2.45 = 245p. Then multiply: 3 × 245 = 735p. Finally convert back: 735p = £7.35. This avoids decimal point confusion. - Placing the decimal point in the wrong position in the answer
Always check: does the answer look sensible? If one item costs about £2.50 and you buy 3, the answer should be about £7.50. If your answer is £75 or £0.75, something has gone wrong.
Tips for Parents
- Use the "convert to pence" method: change pounds to pence, multiply, then convert back. This avoids decimal mistakes.
- Use real shopping situations: "Apples cost £1.35 each. We need 4. How much is that?" Estimate first (about £1.40 × 4 = £5.60), then calculate exactly.
- Practise multiplying prices from takeaway menus: "3 portions of chips at £2.80 each — what is the total?"
- Ask your child to check answers by estimating: "£3.15 × 5 — that is about £3 × 5 = £15, so the exact answer should be close to £15."
Key Words
- Total cost — The full price when you buy several of the same item — found by multiplying the price by the quantity.
- Convert — Change from one unit to another — £2.45 converted to pence is 245p.
- Estimate — A rough answer to check if your exact answer is sensible.
- Quantity — How many of something you are buying.
Where This Fits
Before this topic: Children should know their times tables, understand pounds and pence notation, and be able to multiply two- and three-digit numbers.
After this topic: Multiplying money leads to division of money (sharing costs), percentage discounts, and real-life budgeting problems in Years 5-6.
