Instructions: Use columnar methods to add and subtract numbers with up to four digits. Estimate first where asked, then use the inverse operation to check your answers. For the final problems, read carefully and decide which operations you need.

Add with Columnar Methods

Set out each calculation in columns, keeping the ones, tens, hundreds and thousands in the correct places. Exchange where needed. Estimate each total first by rounding both numbers to the nearest hundred.

1. Estimate: 2,347 + 1,528 ≈ Calculate exactly: 2,347 + 1,528 =

2. Estimate: 4,086 + 2,759 ≈ Calculate exactly: 4,086 + 2,759 =

3. Estimate: 3,615 + 2,284 ≈ Calculate exactly: 3,615 + 2,284 =

4. Estimate: 1,768 + 3,947 ≈ Calculate exactly: 1,768 + 3,947 =

Subtract with Columnar Methods

Write each subtraction in columns and exchange when a digit in the top number is too small. Estimate by rounding both numbers to the nearest hundred, then calculate the exact difference.

1. Estimate: 4,832 − 2,156 ≈ Calculate exactly: 4,832 − 2,156 =

2. Estimate: 7,000 − 3,468 ≈ Calculate exactly: 7,000 − 3,468 =

3. Estimate: 6,251 − 1,784 ≈ Calculate exactly: 6,251 − 1,784 =

4. Estimate: 5,604 − 2,937 ≈ Calculate exactly: 5,604 − 2,937 =

Estimate, Calculate and Check

Round each number to the nearest hundred to make an estimate. Then calculate the exact answer. Check each answer using the inverse operation: addition checks subtraction, and subtraction checks addition.

1. 2,896 + 1,745: Estimate Exact total Inverse check:

2. 6,403 − 2,758: Estimate Exact difference Inverse check:

3. 3,278 + 2,416: Estimate Exact total Inverse check:

4. 8,120 − 3,965: Estimate Exact difference Inverse check:

Find the Missing Number

Use the relationship between addition and subtraction to find each missing number. Write a complete calculation in the working box to show how you checked your answer.

1. 2,465 + ___ = 5,830. Missing number Check

2. ___ + 1,728 = 4,906. Missing number Check

3. 7,240 − ___ = 3,815. Missing number Check

4. ___ − 2,386 = 4,517. Missing number Check

Two-Step Problems

Read each problem and decide which two operations are needed. Write the calculations in order, then give the answer with its unit or context. Use a columnar method when it helps.

1. A library had 2,485 children’s books. It bought 1,276 more, then donated 938 books. How many children’s books does it have now?

2. A school is raising £4,000 for new playground equipment. It raised £1,685 at a fair and £1,247 at a sponsored event. How much more must it raise to reach its target?

3. A coach travelled 1,368 km on Monday and 1,475 km on Tuesday. Its full route is 4,000 km. How many kilometres of the route remain?

4. A farmer collected 3,250 apples. He sold 1,485 in the morning and 976 in the afternoon. How many apples were left?
