Example questions from this paper
A preview of the wording. The answer options and full explanations appear once you begin.
- A shop sells apples at 49p each. Estimate the cost of 5 apples by rounding 49 to the nearest 10.
- There are 298 pupils in a school. To the nearest 100, how many pupils are there?
- A journey is 483 km long. Estimate the distance to the nearest 100 km.
- A school library has 1,247 books. Estimate this to the nearest 1,000.

Before you begin, remember
- 5 or more rounds up, 4 or less rounds down. Watch for 9s: rounding 3,297 to the nearest ten gives 3,300, not 3,290.
- In an estimation question, round every number first and only then calculate. Working it out exactly and rounding at the end wastes the time the question is trying to save you.
