GCSE Maths Estimate Questions
Estimate questions test whether students can round numbers sensibly and find an approximate answer without overcomplicating the calculation.
How To Estimate
- Round numbers to one significant figure where appropriate.
- Use easy numbers that keep the answer sensible.
- Show the rounded calculation.
- Check that the final answer is an estimate.
Exam tip: The word estimate usually means you should round before calculating.
Common mistake: Giving a full calculator answer may lose marks if the question asks for an estimate.
