Rules for Multiplying Positives and Negatives, Model 3

Rules for Multiplying Positives and Negatives, Model 3 is a Grade 7 number-line model for integer multiplication. A moving person or ladybug represents repeated groups and direction, allowing students to model examples such as 2 × 3, -2 × 3, and -2 × -3. The movement helps connect the sign of each factor with both direction and orientation.

Use it as a whole-class conceptual lesson when students need another way to understand why integer products change sign. Challenging students to model 2 × -3 forces them to reason from the number line instead of recalling a rule only.
