Fact Family Multiplication and Division

Multiplication and Division Fact Families

Multiplication and division are related!

• Multiplication and division are related in the same way addition and subtraction are: INVERSE (which means opposite!)

• This means they can UNDO each other

• 5 x 2 = 10, so... 10 ÷ 2 = 5

• 10, 2, and 5 are in the same family
