Grades: 3‒4

Students explore multiplication as a scaling operation to learn and practice multiplication facts up to 10 × 10. Using groups of replicating bugs as visual models of multiplication helps students to conceptualize multiplication as the scaling of one number by another. Through their work, students develop strategies for finding products.

OBJECTIVES

- Students will use a scaling model to explore multiplication.
- Students will develop strategies for computing up to 10 × 10.
