This video introduces fact families for multiplication and division facts.

Apply

Fill in the boxes with the missing numbers to complete the fact family.

  1. $1\times\editable{}=4$1×=4

    $4\times\editable{}=4$4×=4

    $4\div\editable{}=1$4÷​=1

    $\editable{}\div1=4$÷​1=4

 

Remember!

For a multiplication problem such as $4\times3=12$4×3=12, we can write $3$3 other facts to form the fact family. 

$3\times4=12$3×4=12

$12\div3=4$12÷​3=4

$12\div4=3$12÷​4=3

Outcomes

3.OA.C.7

Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g. Knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of grade 3, know from memory all products of two one-digit numbers.
