Every sheet of 2nd grade subtraction without regrouping 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 31 − 10, which works out to 21; another is 46 − 15, giving 31.
‘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.
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 31 − 10 can take three times as long as an addition of the same size.
Every subtraction has an addition hiding inside it, and checking 46 − 15 by adding 31 back to the smaller number is the single most useful habit you can teach on this page.
This sheet uses two-digit numbers that never need a borrow. That is deliberate: wide enough to force real regrouping, narrow enough that a child can still check the answer by adding back.
Because the sheet regenerates, the child meets the borrowing pattern in a different place each time, which is exactly what stops the method from being memorised as a sequence of pen strokes; 47 − 22 today will not borrow in the same column as tomorrow's sheet.
These 2nd grade subtraction without 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 | 31 − 10 = | 21 | Watch for: borrowing across a zero |
| 2 | 46 − 15 = | 31 | Check: reading the minus sign as a plus |
| 3 | 67 − 35 = | 32 | Look at: checking by re-subtracting |
| 4 | 47 − 22 = | 25 | Ask about: counting back one at a time |
| 5 | 91 − 11 = | 80 | Watch for: forgetting to reduce the column that was borrowed from |
| 6 | 47 − 12 = | 35 | Check: subtracting the smaller digit from the larger one |
A good first problem to do together is 31 − 10, which comes out at 21. Do 31 − 10 once with the child narrating, then hand over the pencil and start the clock on the other 20 problems.
The item 46 − 15 is worth doing slowly. The answer to 46 − 15 is 31, 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.
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 21 for 31 − 10.
Answers appear next to their question numbers, so a wrong item like 46 − 15 can be found in the key in a second and re-worked while it is still fresh.
For a class set, print one sheet, press the new-worksheet button and print again. Each child gets different numbers on the same skill, so nobody can copy the answer to 31 − 10 from a neighbour.
To save these 2nd grade subtraction without 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.
