Fact Families—Multiplication and Division

CONCEPT:

What are Fact Families for Multiplication

and Division?

Fact families for multiplication and division are facts

that are directly related. In the fact family, there are two

multiplication problems and two division problems. The

multiplication facts are manifestations of the commutative

property because changing the order does not change

the result of the operation. The division facts are inverse

operations of the multiplication facts.

Formative Assessment

To fi nd out if a student understands multiplication and

division fact families, provide the following incomplete fact

family and ask the student which fact is missing from the

family:

7 x 5 = 35

35 ÷ 7 = 5

35 ÷ 5 = 7

If the student is not successful, try fact families with smaller

numbers. If the student is successful, ask him to generate all

of the facts in the 6, 9, 54 fact family.
