Use this page when you want 3 digit subtraction without 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. A typical problem from the sheet in front of you is 667 − 134, which works out to 533; another is 461 − 121, giving 340.
‘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 three-digit numbers with no borrowing. That is deliberate: wide enough to force real regrouping, narrow enough that a child can still check the answer by adding back.
Fluency here means the child can say why a column needed regrouping, not just that it did. Ask about the column that produced 174 and you will hear the difference immediately.
Every subtraction has an addition hiding inside it, and checking 461 − 121 by adding 340 back to the smaller number is the single most useful habit you can teach on this page.
There are two ways to think about a subtraction such as 667 − 134: taking away, or finding the difference. Children who only know the first find 533 slowly whenever the two numbers are close together.
These 3 digit 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 | 667 − 134 = | 533 | Watch for: subtracting the smaller digit from the larger one |
| 2 | 461 − 121 = | 340 | Check: checking by re-subtracting |
| 3 | 496 − 322 = | 174 | Look at: forgetting to reduce the column that was borrowed from |
| 4 | 916 − 206 = | 710 | Ask about: borrowing across a zero |
| 5 | 972 − 252 = | 720 | Watch for: reading the minus sign as a plus |
| 6 | 989 − 518 = | 471 | Check: counting back one at a time |
Here is one worked through. 461 − 121 gives 340. If your child arrives somewhere other than 340 on 461 − 121, look at the working rather than the answer: nearly every wrong result comes from a skipped step, not an unknown fact.
Try 496 − 322 together before letting the child start alone. The answer to 496 − 322 is 174, and talking through how it was reached takes about a minute and saves several minutes of guessing later in the sheet.
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 533 for 667 − 134.
Every generated sheet carries its own key on a separate printed page, which lets a child self-mark without seeing the answers while they work.
If the problems look cramped, drop the count from 20 to a smaller number before printing these 3 digit subtraction without regrouping worksheets; the font stays the same size and the spacing opens up.
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.
Keep the finished 3 digit subtraction without regrouping worksheets in date order — the drop in time across ten sheets is the clearest progress report you will get.
