Dividing Using an Area Model

This lesson teaches how to divide using an area model. It begins with a review of multiplication and division as inverse operations, followed by breaking down complex multiplication problems. The lesson then demonstrates using an area model to solve division problems, including examples like dividing 3,180 by 15 and distributing 1,438 stickers among 13 students. The lesson emphasizes smart rounding and estimation to simplify calculations.

What is the relationship between multiplication and division?

• They are unrelated operations.

• They are inverse operations.

• They are the same operation.

• They are both addition operations.

In the problem 45 divided by 9 equals n, what is the multiplicative inverse?
