KS2 SATs: Writing Large Numbers Writing large numbers in words and figures is a popular topic for the KS2 Maths Reasoning papers. Some questions will cover the Year 5 Programme of Study, using numbers in the hundreds of thousands, such as writing 120, 345 in words. Others are in the Year 6 Programme, using numbers in the millions.
