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
