What Year 3 subtraction covers

In Year 3, children move on to formal written column subtraction of numbers with up to three digits. These worksheets always put the larger number first, so every answer is a whole number to practise borrowing across hundreds, tens and units. 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 subtraction does Year 3 cover?

Year 3 introduces formal written (columnar) subtraction of numbers with up to three digits. These sheets give three-digit subtractions — the larger number is always on top, so every answer is a whole number.

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. Choose how many questions, make a sheet, then print it or download the PDF. There is no login, ever.
