The Relationship of Multiplication and Division

Curated and Reviewed by Lesson Planet

Take any number, multiply it by five, and then divide by five. Did you end up with the original number? In the same vein as the previous lesson, pupils discover the relationship between multiplication and division. They develop the identities (a/b) x b = a and (a x b)/b = a by constructing tape diagrams.
