What Year 1 maths covers
Year 1 is where the arithmetic starts being written down. Children add and subtract within 20, learn the number bonds that make 10 and then 20 along with the subtraction facts that mirror them, and find a half or a quarter of a small amount. Every sum on the sheet above totals 20 or less, and no subtraction ever goes below zero — which is what “within 20” actually means, and it is a stricter promise than simply keeping the numbers small. The sheet is 18 questions rather than the usual 24. Every sheet is A4, print-ready, and comes with an answer key.
Answers included — a separate marking page with every sheet.
Questions parents ask
What maths does a child learn in Year 1?
Year 1 number work is addition and subtraction within 20. Children learn number bonds — the pairs that make 10, then 20 — and the subtraction facts that go with them, read and write the +, − and = signs, and meet halves and quarters as one of two or one of four equal parts of a shape or a quantity. Counting in twos, fives and tens starts here too, but the times tables themselves do not arrive until Year 2.
Why are there no times tables on this sheet?
Because the national curriculum does not teach them in Year 1. Children count in twos, fives and tens, and they meet multiplication and division only through concrete objects, pictures and arrays, with a teacher alongside them. That is a hands-on activity, not a written sum, so putting 5 × 3 on a Year 1 worksheet would be teaching next year’s content a year early. The 2, 5 and 10 tables begin in Year 2.
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.
