Pounds and pence
£1 is 100p. So £2 is 200p and £3 is 300p.
100p make £1.
Year 3
Add and subtract amounts of money to give change, using both pounds and pence
Add and subtract amounts of money, find change and compare amounts, using pounds and pence.
Lesson overview
Measurement
Money is counted in pounds (£) and pence (p). £1 is the same as 100p. We can say an amount using its pounds and its pence, such as £2 and 30p. We add prices to find a total, and we subtract the cost from the amount paid to find the change.
Add prices
£2 and 30p + £1 and 20p = £3 and 50p.
Add the pounds, then add the pence.
Find change
If you pay with a £5 note for an item costing £3 and 40p, the change is £1 and 60p.
Change is what is left after paying.
Compare amounts
£4 and 10p is more than £3 and 95p.
Compare the pounds first, then the pence.
Worked example
A notebook costs £1 and 75p and a pen costs 65p. What is the total cost?
- Write the two prices clearly.
- Add the pence: 75p + 65p = 140p.
- 140p is £1 and 40p, because £1 is 100p.
- Add the pounds: £1 + £1 = £2. So the total cost is £2 and 40p.
Try it
Read the amount paid and the cost carefully, then decide whether you need a total or change.
Question 1
What is £1 and 20p + 80p?
Question 2
What is the change from £5 if an item costs £2 and 50p?
Question 3
How many pence are in £2? Write the pence number only.
Question 4
Which amount is greater?
Question 5
A toy costs £4 and 25p and you pay £5. What is the change?
Common mistakes
Watch for these when working through the lesson.
- Mixing up total and change.
- Reading 40p as £40.
- Forgetting that 100p make £1 when the pence add up to more than 100.
