Rounding to Powers of 10: Calm Guidance for 11+ Preparation
19 October 2026
Why rounding matters
Rounding to powers of 10 is a key skill for 11+ Maths. It helps children estimate, check answers, and work confidently with large numbers.
Rounding to the nearest ten and hundred
To round to the nearest ten, look at the ones digit. If it is 5 or more, round up. If it is 4 or less, round down. For the nearest hundred, check the tens digit and use the same rule.
Key insight: Visualising on a number line can make rounding clearer for your child.
Rounding to the nearest thousand, ten thousand, and hundred thousand
For thousands, focus on the hundreds digit. For ten thousands, look at the thousands digit. For hundred thousands, check the ten thousands digit. Always use the rule: 5 or above rounds up, 4 or below rounds down.
Practical tips for home support
Practise rounding with real-life examples, such as rounding prices or distances. Encourage your child to explain their thinking out loud. This builds confidence and understanding.
