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 — 512 − 247 — so every answer is a whole number, and the practice is in exchanging 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.

My child was taught "exchanging", not "borrowing" — are they the same thing?

Yes, and exchanging is the word schools use now. Borrowing suggested something was taken and paid back later, which is not what happens. Exchanging describes it properly: one ten is swapped for ten ones so the units column can be completed, or one hundred for ten tens so the tens column can. If your child says exchange, use their word — the method on these sheets is identical either way.

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.
