# Divide a 3 digit number by a 1 digit number using area or array model

## Interactive practice questions

Let's use an area model to find the answer to $133\div7$133÷​7.

a

We set up the area model using a rectangle like this.

 $7$7 Total area: $133$133

Now if we don't know straight away what $133\div7$133÷​7 is, we start with something we do know, like groups of $10$10.

Fill in the area used so far if we take out $10$10 groups of $7$7.

 $10$10 $7$7 $\editable{}$ Total area: $133$133
b

How much area is remaining?

 $10$10 $7$7 $70$70 $\editable{}$ Total area: $133$133
c

What is the width of the second rectangle?

 $10$10 $\editable{}$ $7$7 $70$70 $63$63 Total area: $133$133
d

Using the area model above, what is $133\div7$133÷​7?
