Adding Integers Worksheets
Every problem has at least one negative number, since adding two positives is not integer practice. Negatives that come second are written in parentheses, −7 + (−3), the form used in most textbooks. Ranges go from −10 to 10 for a first lesson up to −100 to 100 for fluency. Twenty problems in four columns, thirty for a timed set.

FAQ
Why the parentheses around the second number?
So the two signs do not run together: 5 + −3 is hard to read and easy to miscopy. Parentheses are the convention in most curricula; students may drop them in their own working.
Do the downloads include answer keys?
Yes, every PDF ends with a key page that repeats the layout with the answers in green. Turn the Answer key switch off for a problems-only file.
Can I get different versions for each student?
Turn on the 5 versions switch before downloading. You get five different sheets in one PDF, each with its own answer key, so neighbouring desks cannot copy.
What do the ranges mean?
The largest absolute value on the page: ±10, ±20 or ±100. Sums can be a little larger than the range when both numbers are negative.
Can students work these on a tablet?
Yes. Practice online puts a pen tool over the same sheet, so answers can be written with a stylus or finger and wiped for another try.
