Use this page when you want 2 digit addition 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. You will see items like 34 + 69 and 13 + 69 on the printed page, with 103 and 82 waiting on the answer key so nobody has to redo the arithmetic.
‘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.
Addition is the first place a child meets the idea of a carried digit, and it is the skill every later algorithm leans on. A sheet like 34 + 69 looks small, but the habit it builds — line up the places, work right to left, record the carry — is the same habit that survives into multi-digit multiplication.
Fluency in addition is usually described in two parts: knowing the single-digit facts by recall, and applying a written method to bigger numbers. This sheet exercises whichever of the two the number range implies — for 34 + 69 the answer 103 should come from memory, not from counting.
Written addition is worth practising in columns — which is what these 2 digit addition with regrouping worksheets ask for — even when a child working at this level can do it mentally, because the column layout is what makes four-digit work manageable later. A problem such as 39 + 27 is small enough to do mentally and worth writing out anyway.
Because the addends are regenerated every time, a child cannot learn the sheet instead of the skill. Yesterday's page may have asked for 67 + 27; today's asks something else in the same shape.
Teachers usually place 2 digit addition with regrouping worksheets alongside the addition 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 | 34 + 69 = | 103 | Watch for: forgetting the carried digit |
| 2 | 13 + 69 = | 82 | Check: guessing on the near-tens |
| 3 | 67 + 27 = | 94 | Look at: losing the place columns |
| 4 | 39 + 27 = | 66 | Ask about: treating a longer number as a bigger one |
| 5 | 23 + 68 = | 91 | Watch for: counting on from the wrong number |
| 6 | 28 + 78 = | 106 | Check: adding right to left, then reading left to right |
Take the first problem on the sheet as it stands, 34 + 69. Work 34 + 69 out on paper rather than in your head the first few times, say each step aloud, and check the result against 103 on the key before moving on.
A good first problem to do together is 34 + 69, which comes out at 103. Do 34 + 69 once with the child narrating, then hand over the pencil and start the clock on the other 20 problems.
Keys are produced by the same code that produces the questions, so a mismatch between question and answer is not possible on these sheets.
The answer key is generated with the worksheet, not written by hand, so it always matches the sheet in front of you — 34 + 69 is listed as 103, 13 + 69 as 82, and so on down the page.
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.
If the problems look cramped, drop the count from 20 to a smaller number before printing these 2 digit addition with regrouping worksheets; the font stays the same size and the spacing opens up.
Keep the finished 2 digit addition with regrouping worksheets in date order — the drop in time across ten sheets is the clearest progress report you will get.
