Free 1st Grade Subtraction Worksheets (single digits)

If you need 1st grade subtraction worksheets that you can print right now, this page builds them for you — 20 fresh problems, an answer key underneath, and no account to create first. A typical problem from the sheet in front of you is 4 − 2, which works out to 2; another is 5 − 1, giving 4.

📄 1ST GRADE SUBTRACTION WORKSHEETS — A NEW SHEET EVERY TIME YOU PRESS THE BUTTON
🎲 New set of problems

‘New set of problems’ opens the generator in its own tab. There you can change the problem count and turn the answer key on or off. ‘Print or save as PDF’ opens the print dialog — choose Save as PDF in the printer list to keep the file. The sheet fits US Letter and A4, and the answer key prints on its own page.

What you are practising here

Subtraction is where arithmetic confidence is usually won or lost. The written method itself is short, but it demands that the child hold a borrowed ten in their head while working on the next column — which is why 4 − 2 can take three times as long as an addition of the same size.

Fluency here means the child can say why a column needed regrouping, not just that it did. Ask about the column that produced 4 and you will hear the difference immediately.

There are two ways to think about a subtraction such as 4 − 2: taking away, or finding the difference. Children who only know the first find 2 slowly whenever the two numbers are close together.

This sheet uses single digits, 2 through 9. That is deliberate: wide enough to force real regrouping, narrow enough that a child can still check the answer by adding back.

These 1st grade subtraction worksheets are commonly aligned with the subtraction strand of most US state standards for this grade, and the skill appears in most curricula somewhere around this point.

Examples taken from this worksheet

These six come from the sheet loaded on this page. Press the button and the numbers change, but the shape stays the same (single digits, 2 through 9).
#ProblemAnswerWhat to check
14 − 2 =2Watch for: forgetting to reduce the column that was borrowed from
25 − 1 =4Check: checking by re-subtracting
38 − 4 =4Look at: borrowing across a zero
46 − 5 =1Ask about: counting back one at a time
52 − 1 =1Watch for: subtracting the smaller digit from the larger one
69 − 4 =5Check: reading the minus sign as a plus

Try one together first

Work 6 − 5 out loud as a demonstration. It gives 1. Children who hear 6 − 5 reasoned through once at the start of a session make noticeably fewer errors in the ten minutes that follow.

Here is one worked through. 5 − 1 gives 4. If your child arrives somewhere other than 4 on 5 − 1, look at the working rather than the answer: nearly every wrong result comes from a skipped step, not an unknown fact.

Three things that go wrong here

Using this sheet as a daily drill

  1. If two days in a row come out under 8 minutes with everything correct, that is the signal to move up: either numbers bigger than 4 − 2 uses, or the next skill in the sequence.
  2. Read the first two problems out loud together before starting the clock. It costs fifteen seconds and removes most of the 'I did not understand the question' errors.
  3. Mark it together straight away while the working is still fresh, so a slip like the one behind 8 − 4 can be talked through instead of guessed at.
  4. Use a pencil, not a pen. Children working on subtraction rethink far more often when erasing is allowed, and you get to see exactly where the rethinking happened on an item like 8 − 4.
  5. Write the finish time and the score at the top of every sheet. Two weeks of those two numbers tells you more about progress on subtraction than any single test result.

About the answer key

Keys are produced by the same code that produces the questions, so a mismatch between question and answer is not possible on these sheets.

The answer key is generated with the worksheet, not written by hand, so it always matches the sheet in front of you — 4 − 2 is listed as 2, 5 − 1 as 4, and so on down the page.

Printing on US Letter or A4

Portrait orientation is what the sheet is designed for. Landscape works but wastes about a third of the paper, so leave the orientation alone unless you have a reason.

To save these 1st grade subtraction worksheets instead of printing them, choose 'Save as PDF' in the printer list. You get the worksheet and the answer key as a single PDF, on Letter or A4 depending on your printer settings.

Frequently asked questions

Can I change how many problems are on the page?
Yes — the generator takes 10, 20 or 30 problems. Twenty is the default because it fits one page and suits a 8-minute drill.
How do I check the answers quickly?
Add the answer to the number that was taken away. For the item that gives 2, adding it back should return the starting number exactly.
Should we use a number line?
A number line is a good bridge for small differences and a poor tool once the sheet uses single digits, 2 through 9. Use it to explain, then drop it — the written method is what scales.
Is the answer key included?
Yes, on its own page behind the worksheet. For the sheet loaded right now it shows 2 for 4 − 2 and 4 for 5 − 1.

Keep the finished 1st grade subtraction worksheets in date order — the drop in time across ten sheets is the clearest progress report you will get.
