2 Digit Minus 1 Digit Subtraction Worksheets

This page makes free printable 2 digit minus 1 digit subtraction worksheets on demand: press the button and you get a new sheet of 20 problems with a matching answer key, ready for US Letter or A4 paper. The current sheet starts with problems like 52 − 3 and 43 − 6, and the answers (49 and 37) are printed on the key so marking takes about a minute.

📄 2 DIGIT MINUS 1 DIGIT SUBTRACTION — 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.

The skill behind these problems

Fluency here means the child can say why a column needed regrouping, not just that it did. Ask about the column that produced 59 and you will hear the difference immediately.

Every subtraction has an addition hiding inside it, and checking 43 − 6 by adding 37 back to the smaller number is the single most useful habit you can teach on this page.

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 52 − 3 can take three times as long as an addition of the same size.

There are two ways to think about a subtraction such as 52 − 3: taking away, or finding the difference. Children who only know the first find 49 slowly whenever the two numbers are close together.

These 2 digit minus 1 digit 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.

A sample of this sheet, with answers

These six come from the sheet loaded on this page. Press the button and the numbers change, but the shape stays the same (a two-digit number minus a one-digit number).
#ProblemAnswerWhat to check
152 − 3 =49Watch for: forgetting to reduce the column that was borrowed from
243 − 6 =37Check: checking by re-subtracting
368 − 9 =59Look at: subtracting the smaller digit from the larger one
461 − 8 =53Ask about: borrowing across a zero
546 − 8 =38Watch for: counting back one at a time
632 − 2 =30Check: reading the minus sign as a plus

A worked example from this sheet

Take the first problem on the sheet as it stands, 52 − 3. Work 52 − 3 out on paper rather than in your head the first few times, say each step aloud, and check the result against 49 on the key before moving on.

Work 61 − 8 out loud as a demonstration. It gives 53. Children who hear 61 − 8 reasoned through once at the start of a session make noticeably fewer errors in the ten minutes that follow.

Where children usually slip up

How to run this as a 10-minute daily drill

  1. 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 a two-digit number minus a single digit than any single test result.
  2. Mark it together straight away while the working is still fresh, so a slip like the one behind 68 − 9 can be talked through instead of guessed at.
  3. Stop the session at the time limit even if the sheet is unfinished, and note where the child got to. A half sheet done well is better data than a whole sheet rushed.
  4. Use a pencil, not a pen. Children working on a two-digit number minus a single digit rethink far more often when erasing is allowed, and you get to see exactly where the rethinking happened on an item like 68 − 9.
  5. Keep the session to about 10 minutes. A child working at this level who is still counting on fingers will need longer than that on a line like 52 − 3, and that is fine: the timer is a measurement, never a punishment.

About the answer key

Answers appear next to their question numbers, so a wrong item like 43 − 6 can be found in the key in a second and re-worked while it is still fresh.

Because the numbers are random, there is no shared answer list to look up: the key printed behind your sheet is the only one that fits it, and it shows 49 for 52 − 3.

How to print this worksheet

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 2 digit minus 1 digit 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

How do I check the answers quickly?
Add the answer to the number that was taken away. For the item that gives 49, 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 a two-digit number minus a one-digit number. Use it to explain, then drop it — the written method is what scales.
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 10-minute drill.
Will these print correctly on A4?
Yes. These 2 digit minus 1 digit subtraction worksheets fit both A4 and US Letter without clipping, as long as print scaling is left at 100% and browser headers and footers are switched off.

One sheet of 2 digit minus 1 digit subtraction worksheets a day for two weeks will tell you more about where a child working at this level actually stands than any single long assessment.
