Use this page when you want 2 digit subtraction with regrouping worksheets in the next thirty seconds: choose how many problems you want, press print, and the answer key comes out on its own page behind the worksheet. The current sheet starts with problems like 34 − 27 and 43 − 17, and the answers (7 and 26) are printed on the key so marking takes about a minute.
‘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.
There are two ways to think about a subtraction such as 34 − 27: taking away, or finding the difference. Children who only know the first find 7 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 4 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 34 − 27 can take three times as long as an addition of the same size.
This sheet uses two-digit numbers that always borrow. That is deliberate: wide enough to force real regrouping, narrow enough that a child can still check the answer by adding back.
These 2 digit subtraction with regrouping 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.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | 34 − 27 = | 7 | Watch for: counting back one at a time |
| 2 | 43 − 17 = | 26 | Check: checking by re-subtracting |
| 3 | 91 − 87 = | 4 | Look at: reading the minus sign as a plus |
| 4 | 34 − 18 = | 16 | Ask about: borrowing across a zero |
| 5 | 61 − 46 = | 15 | Watch for: subtracting the smaller digit from the larger one |
| 6 | 44 − 25 = | 19 | Check: forgetting to reduce the column that was borrowed from |
The item 43 − 17 is worth doing slowly. The answer to 43 − 17 is 26, and the route to it is the route every other problem on this sheet takes — which is why the sheet has 20 of them rather than one.
Take the first problem on the sheet as it stands, 34 − 27. Work 34 − 27 out on paper rather than in your head the first few times, say each step aloud, and check the result against 7 on the key before moving on.
The answer key is generated with the worksheet, not written by hand, so it always matches the sheet in front of you — 34 − 27 is listed as 7, 43 − 17 as 26, and so on down the page.
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 7 for 34 − 27.
Printing works the same on US Letter and A4, because the layout uses relative widths rather than fixed inches. Set margins to default and scaling to 100%, and all 20 problems fit.
To save these 2 digit subtraction with regrouping 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.
