If you need adding integers worksheets that you can print right now, this page builds them for you — 20 fresh problems, an answer key underneath, and no account to create first. The current sheet starts with problems like (-2) + (10) and (-10) + (-11), and the answers (8 and -21) 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.
Because the numbers regenerate, the sign combination changes every problem rather than settling into a run.
A number line is the honest model here: adding moves right, subtracting moves left, and negative numbers simply start you left of zero.
Subtracting a negative is the step that needs its own explanation. Removing a debt leaves you better off, which is why the two minus signs turn into a plus.
For multiplication and division the rule is mechanical: same signs give a positive, different signs give a negative. State it separately from the addition rules, or the two get blended and -21 comes out with the wrong sign.
Work of this kind is commonly aligned with the number system strand for grade 6; schools outside the US meet the same skill at roughly the same age, which is why these adding integers worksheets travel well.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | (-2) + (10) = | 8 | Watch for: subtracting the smaller from the larger regardless of position |
| 2 | (-10) + (-11) = | -21 | Check: treating a negative sign as belonging to the operation |
| 3 | (-8) + (7) = | -1 | Look at: applying the multiplication sign rules to addition |
| 4 | (-16) + (-8) = | -24 | Ask about: guessing on zero pairs |
| 5 | (-10) + (13) = | 3 | Watch for: dropping the sign in the answer |
| 6 | (-15) + (14) = | -1 | Check: misreading a double negative |
Here is one worked through. (-10) + (-11) gives -21. If your child arrives somewhere other than -21 on (-10) + (-11), look at the working rather than the answer: nearly every wrong result comes from a skipped step, not an unknown fact.
A good first problem to do together is (-2) + (10), which comes out at 8. Do (-2) + (10) 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 key prints on its own page by default. Uncheck the answer-key box before printing if you would rather keep it back and mark the sheet yourself.
The sheet is laid out to fit one page on both US Letter and A4. Leave the browser scaling at 100% and turn headers and footers off, and the 20 problems land inside the margins on either paper size.
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.
Keep the finished adding integers worksheets in date order — the drop in time across ten sheets is the clearest progress report you will get.
