What KS1 maths covers

Key Stage 1 is Years 1 and 2. Over the two years children go from adding and subtracting within 20 to working within 100, learn the number bonds and the subtraction facts that mirror them, meet their first three times tables — 2, 5 and 10 — with the division facts that go with them, and find halves, thirds and quarters of a quantity. The sheet above spans both years and leans on addition and subtraction, because those are the skills the rest of the key stage is built on. Every sheet is A4, print-ready, and comes with an answer key.

Answers included — a separate marking page with every sheet.

Key Stage 1 by year

Practise one year at a time:

Year 1 maths →

Addition and subtraction within 20, number bonds, halves and quarters. No tables yet.

Year 2 maths →

The 2, 5 and 10 tables arrive; addition and subtraction move up to 100.

Questions parents ask

What does KS1 maths cover?

Key Stage 1 is Years 1 and 2 — ages five to seven. Across the two years children move from adding and subtracting within 20 to working within 100, learn the number bonds and the matching subtraction facts, pick up the 2, 5 and 10 times tables and the division facts that go with them, and find halves, thirds and quarters of a quantity. It ends with the Year 2 national curriculum tests, which most schools still call the KS1 SATs.

Should I use this sheet or a year sheet?

Use a year sheet if you know the year group — Year 1 keeps every sum within 20 and leaves the tables out entirely, and Year 2 introduces them. Use this one to revise the key stage as a whole, which is what a Year 2 child does in the summer term, or when a child sits between the two years. It leans on addition and subtraction because those are the KS1 skills everything else is built on, and because Year 1 contributes nothing else.

Are the answers included?

Yes. Keep 'Answers' ticked and a separate answer-key page is made with every sheet, so marking takes seconds. Every answer is computed exactly and checked.

Do I need to sign up?

No. Set the sheet up, make it, then print it or download the PDF. There is no login, ever.
