Rounding money amounts to estimate totals and check if answers are reasonable.
Where your child meets this in real life: Checking if you have enough money, budgeting, quick mental calculations
SEAGReady breaks estimate with money into 2 steps, taught in order so each skill builds on the last.
Round money amounts to the nearest pound and estimate the total cost of 2-3 items
Use estimation to check if an exact calculation is reasonable or if available money is sufficient
Three free sample questions from our estimate with money course. Every question comes with a full explanation, and hints that guide without giving the answer away.
Sean is buying a magazine for £4.85 and a drink for £1.15 at the newsagent. Estimate the total cost by rounding to the nearest pound.
Answer: A. about £6
Round each price to the nearest pound: £4.85 → £5 (85p is more than 50p, so round up) £1.15 → £1 (15p is less than 50p, so round down) Add the rounded amounts: £5 + £1 = £6 The estimated total is about £6.
Stuck? Start here: First, round each price to the nearest pound. Look at the pence to decide.
Conor has £10. He wants to buy a toy for £4.95 and a book for £2.10. Use estimation to decide: does Conor have enough money?
Answer: A. Yes, he has enough
Round each price to the nearest pound: £4.95 → £5 (95p rounds up) £2.10 → £2 (10p rounds down) Estimate: £5 + £2 = £7 Compare: £7 < £10 Yes, Conor has enough money. (The exact total is £7.05, which is less than £10.)
Stuck? Start here: Round each price to the nearest pound and estimate the total.
Ciara wants to buy a sandwich for £3.75 and a juice for £2.25 at the school canteen. Estimate the total cost by rounding to the nearest pound.
Answer: B. about £6
Round each price to the nearest pound: £3.75 → £4 (75p is more than 50p, so round up) £2.25 → £2 (25p is less than 50p, so round down) Add the rounded amounts: £4 + £2 = £6 The estimated total is about £6.
Stuck? Start here: Round each price to the nearest pound first. Look at the pence.
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Aoife is buying a sandwich for £3.85 and a smoothie for £2.15 at the school canteen.
Estimate the total cost by rounding to the nearest pound.
£3.85 + £2.15 ≈ ?
Step 1 of 3
Aoife is buying a sandwich for £3.85 and a smoothie for £2.15 at the school canteen.
Estimate the total cost by rounding to the nearest pound.
The total is approximately £6.
The key insight: Rounding to the nearest pound makes adding much easier in your head!
Watch out: £3.85 rounds to £3. Look at the pence: 85p is more than 50p, so round UP to £4, not down to £3.
These are the misconceptions we see most often in estimate with money, including the ones our practice questions are specifically designed to catch.
Struggling with estimate with money? The real gap is often in one of these earlier topics.
SEAGReady finds the exact step where your child gets stuck, teaches it with worked examples like the one above, and brings it back for review so it sticks.
