Every sheet of 3 digit minus 2 digit subtraction worksheets on this page is built the moment you open it, so the 20 problems below are not the same ones the last visitor printed, and the answer key is generated with them. A typical problem from the sheet in front of you is 259 − 20, which works out to 239; another is 254 − 64, giving 190.
‘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.
This sheet uses a three-digit number minus a two-digit number. That is deliberate: wide enough to force real regrouping, narrow enough that a child can still check the answer by adding back.
There are two ways to think about a subtraction such as 259 − 20: taking away, or finding the difference. Children who only know the first find 239 slowly whenever the two numbers are close together.
Fluency here means the child can say why a column needed regrouping, not just that it did. Ask about the column that produced 519 and you will hear the difference immediately.
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 259 − 20 can take three times as long as an addition of the same size.
Teachers usually place 3 digit minus 2 digit subtraction worksheets alongside the subtraction strand of most US state standards for this grade, which is where the skill sits in the majority of US state frameworks.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | 259 − 20 = | 239 | Watch for: reading the minus sign as a plus |
| 2 | 254 − 64 = | 190 | Check: borrowing across a zero |
| 3 | 553 − 34 = | 519 | Look at: counting back one at a time |
| 4 | 121 − 22 = | 99 | Ask about: forgetting to reduce the column that was borrowed from |
| 5 | 731 − 34 = | 697 | Watch for: subtracting the smaller digit from the larger one |
| 6 | 610 − 78 = | 532 | Check: checking by re-subtracting |
A good first problem to do together is 259 − 20, which comes out at 239. Do 259 − 20 once with the child narrating, then hand over the pencil and start the clock on the other 20 problems.
Here is one worked through. 254 − 64 gives 190. If your child arrives somewhere other than 190 on 254 − 64, look at the working rather than the answer: nearly every wrong result comes from a skipped step, not an unknown fact.
Answers appear next to their question numbers, so a wrong item like 254 − 64 can be found in the key in a second and re-worked while it is still fresh.
The answer key is generated with the worksheet, not written by hand, so it always matches the sheet in front of you — 259 − 20 is listed as 239, 254 − 64 as 190, and so on down the page.
To save these 3 digit minus 2 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.
If the problems look cramped, drop the count from 20 to a smaller number before printing these 3 digit minus 2 digit subtraction worksheets; the font stays the same size and the spacing opens up.
One sheet of 3 digit minus 2 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.
