Multiplication Strategies—Multipliers 6 through 12

MULTIPLICATION STRATEGIES—MULTIPLIERS 6 THROUGH 12

Grades: 3‒4

Students use a rectangular array model to develop strategies for decomposing multiplication problems into simpler problems with numbers whose products they already know. By practicing with the array models, students learn and increase their fluency with multiplication facts for 6’s, 7’s, 8’s, 9’s, 11’s, and 12’s.

OBJECTIVES

Students will use a rectangular array model to explore multiplication facts for 6’s, 7’s, 8’s, 9’s, 11’s, and 12’s.
Students will see the relationship between a multiplication fact represented in numerical form and the same fact represented with an array.
Students will develop and use strategies such as the distributive property for computing multiplication facts.
