The following diagram shows how to use the distributive property to multiply and divide. Scroll down the page for more examples.
Use the 5 plus something break apart and distribute strategy to solve 6 × 8. Model with a tape diagram.
Note: This problem reviews modeling the break apart and distribute strategy using a tape diagram from Lesson 6. Until today’s lesson students have learned to break apart the first factor and distribute the second factor. Today’s Concept Development reverses the order using the fact in this Application Problem.
Problem 1: Multiply.
Problem 2: Divide.
Use the break apart and distribute strategy to solve 6 × 8.
6 × 8 = 6 × (5 + 3)
Use the break apart and distribute strategy to solve 64 ÷ 8.
64 ÷ 8 = (40 ÷ 8) + 24 ÷ 8
