## Interactive practice questions

Let's use an area model to find the answer to $36\div3$36÷​3.

a

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

 $3$3 Total area: $36$36

Now if we don't know what $36\div3$36÷​3 is straight away, 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 $3$3.

 $10$10 $3$3 $\editable{}$ Total area: $36$36
b

How much area is remaining?

 $10$10 $3$3 $30$30 $\editable{}$ Total area: $36$36
c

What is the width of the second rectangle?

 $10$10 $\editable{}$ $3$3 $30$30 $6$6 Total area: $36$36
d

Using the area model above, what is $36\div3$36÷​3?
