Integer Multiplication Worksheets — Negative Numbers Practice

Integer operations — working with negative numbers — are the gateway to algebra. These worksheets focus on multiplication of positive and negative integers, where the sign rules (positive × negative = negative, negative × negative = positive) are the core skill. The range control lets you keep numbers small for the first pass or widen them for fluency work.

Teaching tips for integers

  • •Teach the sign rules as a short, memorable table: same signs → positive, different signs → negative. Drill the table before mixing it into computation.
  • •Use a number line or temperature metaphor to make negative numbers concrete before applying the rules abstractly.
  • •Keep the range tight (−10 to 10) while learning the rules; widen to −20 to 20 once sign handling is automatic.

Common mistakes to watch for

✗ Getting the sign wrong: forgetting that two negatives multiply to a positive.
✓ Count the negatives: an even number of negative factors gives a positive product, an odd number gives negative. Check the sign as a separate step from the value.
✗ Mixing up −2 × 3 with −2 + 3.
✓ Say the operation out loud: "negative two TIMES three". Multiplication is repeated addition but the rule is different — separate the two skills in practice.

Frequently Asked Questions

What grade are integer worksheets for?

Negative numbers are introduced in grade 6 (6.NS.C.6) and operations with integers are formalized in grades 6–7 (7.NS.A.1, 7.NS.A.2).

Why start with multiplication instead of addition?

Integer multiplication has a clean sign rule that students can verify with a number line. Integer addition with negatives is covered by the subtraction generator when you enable negative answers.

Can I print just problems for a quiz?

Yes — toggle off "Include answer key" for the quiz copy and print a second sheet with answers for quick grading.
