Instructions: Work through each activity, showing a clear method where useful. For mental calculations, look for ways to adjust numbers or use inverse operations. Estimate first where asked, then compare your estimate with your exact answer.

Mental Maths: Large Numbers

Calculate each one mentally where possible. Use place-value partitioning, compensation or the inverse operation to help. Write each answer in its box.

1. 468,000 + 35,000 =

2. 720,000 − 48,000 =

3. 2,450,000 + 550,000 − 125,000 =

4. 6,300,000 − 1,800,000 + 250,000 =

5. 999,999 + 1,000 − 99,999 =

Order of Operations

Use the order of operations: calculate brackets first, then multiplication and division, followed by addition and subtraction. Work carefully from left to right when operations have equal priority.

1. 48 + 6 × 7 =

2. (125 − 35) ÷ 5 + 18 =

3. 240 − 8 × 15 + 36 ÷ 6 =

4. 360 ÷ (12 − 6) + 4 × 9 =

5. 500 − (72 ÷ 8 + 6) × 7 =

Multi-Step Problems: Money and Measures

Choose the operations needed and show your working. Keep track of units, and give each final answer in the unit requested.

1. A school orders 248 exercise books at £3 each and 175 folders at £4 each. What is the total cost?

2. A charity walk route is 18.6 km. A group walks 7.85 km before lunch and 6.9 km after lunch. How many kilometres remain?

3. A theatre has 1,250 seats. For a show, 875 tickets are sold on Friday and 296 on Saturday. How many seats are empty?

4. A warehouse packs 36 boxes with 125 bottles in each. It sends 2,750 bottles to one shop. How many bottles remain?

Estimate, Calculate and Check

Round each number to a suitable place value to estimate. Then calculate exactly and use the inverse operation or your estimate to check whether your answer is reasonable.

1. Estimate, then calculate: 398,742 + 201,386. Estimate: Exact answer:

2. Estimate, then calculate: 805,120 − 297,845. Estimate: Exact answer:

3. Estimate, then calculate: 4,982,671 + 1,019,438. Estimate: Exact answer:

4. Estimate, then calculate: 7,000,000 − 3,486,290. Estimate: Exact answer:

Mixed Operations in Context

Read each problem closely and decide which operations to use. Show enough working to make your method clear, and include the unit in your answer where appropriate.

1. A stadium has 48,500 seats. It is full for a match. If 17,850 supporters leave at half-time and 6,275 return, how many people are in the stadium then?

2. A printer makes 2,400 leaflets each day for 5 days. It posts 3,750 leaflets, then recycles the rest. How many leaflets are recycled?

3. A family drives 286 km on Saturday and 347 km on Sunday. Their weekly target is 800 km. How many kilometres short of the target are they?

4. A shop starts with £12,500 in its account. It receives £3,875, pays a supplier £4,960 and then receives £1,250. What is the balance now?
