# Multiplication and division (turn arounds and fact families) (10x10)

Lesson

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.

1. $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 to complete the fact family.

1. $4\times2=\editable{}$4×2=

$2\times\editable{}=8$2×=8

$8\div\editable{}=4$8÷​=4

$\editable{}\div4=2$÷​4=2

##### question 3:

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

1. $10\times8=\editable{}$10×8=

$8\times\editable{}=80$8×=80

$80\div\editable{}=10$80÷​=10

$\editable{}\div10=8$÷​10=8
