How to Read and Write Large Numbers for 11+ Maths
19 October 2026
Understanding large numbers
Reading and writing large numbers is a key skill for the 11+ maths exam. Children may face numbers in the thousands, millions, or even higher. It is important to recognise each digit's value and be able to say and write numbers correctly.
Breaking numbers into parts
A helpful way to approach large numbers is to break them into groups of three digits, separated by commas. For example, 5,432,189 is read as 'five million, four hundred and thirty-two thousand, one hundred and eighty-nine'. Encourage your child to practise saying numbers aloud and writing them in words.
Common challenges and how to help
Some children mix up place values or miss out zeros when writing numbers. Practise reading numbers both in digit and word form. Use real-life examples, such as population figures or distances, to make the skill more familiar.
Key insight: Confidence with reading and writing large numbers is built through regular practice and clear breakdowns. Mistakes often happen when children rush or do not check each part of the number, so encourage a calm, step-by-step approach.
