Multiplication and division (turn arounds and fact families) (0,1,2,3,5,10)
Turn arounds and fact families are important to know when solving maths problems. each multiplication fact has a turn around fact, where you turn around the factors you are multiplying to get the same answer. We can then build fact families from these using division.
I will explain this in more detail in the following video.
Worked Examples:
Question 1
Fill in the boxes with the missing numbers to complete the fact family.
$5\times\editable{}=5$5×=5
$1\times\editable{}=5$1×=5
$5\div\editable{}=5$5÷=5
$\editable{}\div5=1$÷5=1
Question 2:
Fill in the boxes with the missing numbers.
$3\times3=\editable{}$3×3=
$3\times\editable{}=9$3×=9
$9\div\editable{}=3$9÷=3
$\editable{}\div3=3$÷3=3
question 3:
Fill in the boxes with the missing numbers to complete the fact family.
$0\times6=\editable{}$0×6=
$6\times\editable{}=0$6×=0
$\editable{}\div6=0$÷6=0
What does $6\div0$6÷0 equal?
$6$6
AWe can't evaluate $6\div0$6÷0
B$0$0
C$1$1
