Use this page when you want 6th grade integers 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. Right now the generator is set to problems such as (15) + (-5) (answer 10) and (-19) − (-2) (answer -17); press the button again and the numbers change while the skill stays the same.

📄 6TH GRADE INTEGERS WORKSHEETS — A NEW SHEET EVERY TIME YOU PRESS THE BUTTON
🎲 New set of problems

‘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.

The skill behind these problems

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 -17 comes out with the wrong sign.

A number line is the honest model here: adding moves right, subtracting moves left, and negative numbers simply start you left of zero.

Negative numbers break the rule that arithmetic makes things bigger, and that is the whole difficulty. Working (15) + (-5) to 10 means thinking about direction as well as size.

This sheet uses integers from −20 to 20, which keeps the arithmetic small so the sign rules get the attention.

In US classrooms these 6th grade integers worksheets are commonly aligned with the number system strand for grade 6, though the exact wording varies from state to state.

A sample of this sheet, with answers

These six come from the sheet loaded on this page. Press the button and the numbers change, but the shape stays the same (integers from −20 to 20).
#ProblemAnswerWhat to check
1(15) + (-5) =10Watch for: subtracting the smaller from the larger regardless of position
2(-19) − (-2) =-17Check: applying the multiplication sign rules to addition
3(12) + (-19) =-7Look at: dropping the sign in the answer
4(-2) − (-2) =0Ask about: guessing on zero pairs
5(-12) + (13) =1Watch for: treating a negative sign as belonging to the operation
6(-3) − (-1) =-2Check: misreading a double negative

Try one together first

Work (-2) − (-2) out loud as a demonstration. It gives 0. Children who hear (-2) − (-2) reasoned through once at the start of a session make noticeably fewer errors in the ten minutes that follow.

A good first problem to do together is (15) + (-5), which comes out at 10. Do (15) + (-5) once with the child narrating, then hand over the pencil and start the clock on the other 20 problems.

Three mistakes we see most often

Getting the most out of 12 minutes a day

  1. Re-print the same skill rather than the same sheet. Because the numbers change, a child who memorised that (15) + (-5) gives 10 still has to actually calculate tomorrow.
  2. If two days in a row come out under 12 minutes with everything correct, that is the signal to move up: either numbers bigger than (15) + (-5) uses, or the next skill in the sequence.
  3. Run the sheet at the same time each day. Ten focused minutes before dinner beats an hour on Sunday, because integers is a recall skill: (15) + (-5) has to arrive without being worked out, and recall is built by frequency.
  4. Write the finish time and the score at the top of every sheet. Two weeks of those two numbers tells you more about progress on integers than any single test result.
  5. Do not raise the number of problems until the accuracy is steady. Going from 20 correct-but-slow problems to more problems only multiplies the same mistake.

Marking the sheet

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.

How to print this worksheet

If the problems look cramped, drop the count from 20 to a smaller number before printing these 6th grade integers worksheets; the font stays the same size and the spacing opens up.

To save these 6th grade integers 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.

Frequently asked questions

How many different sheets can I make?
As many as you want. The numbers are randomised each time, so printing five sheets in a row gives five different sets of 20 problems on the same skill.
Is a number line still useful at this level?
Yes, for addition and subtraction — it makes direction visible. For multiplication and division the sign rules are quicker.
Will these print correctly on A4?
Yes. These 6th grade integers worksheets fit both A4 and US Letter without clipping, as long as print scaling is left at 100% and browser headers and footers are switched off.
Why does subtracting a negative give a positive?
Because subtracting means removing, and removing a negative amount leaves more than you had. Cancelling a debt of ten leaves you ten better off.

One sheet of 6th grade integers worksheets a day for two weeks will tell you more about where a 6th grader actually stands than any single long assessment.
