Multiplying Integers

Multiplying Integers is a Grade 7 whole-class investigation focused on understanding why a negative multiplied by a negative is positive. Students begin with a familiar pattern such as -2 × 3, -2 × 2, -2 × 1, and -2 × 0, then continue the pattern into negative factors. A number-line model helps make the change in products visible.

Use it when students need more than a rule to remember about integer multiplication. Extending the pattern step by step lets the class reason toward the sign result instead of accepting it as an arbitrary convention.
