Tips for parents and carers
- Ask “Is this answer sensible?” before checking any maths.
- Try estimating at home: how many books are on the shelf?
- There is no single right answer. A good estimate is close enough, with a clear method.
Using Estimate It! with a group or class
- Let groups discuss the question, then make an estimate. Compare the range of estimates, and talk about the methods.

Frequently asked questions
Why estimate?
Estimating helps children decide whether answers are sensible and builds a sense of size and scale.
Is there a right answer?
There is a sensible range. The method matters more than getting an exact figure.
How do I estimate something big?
Break it into smaller parts you can estimate, then multiply or add.
