Interactive practice questions

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


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

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.

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

How much area is remaining?

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

What is the width of the second rectangle?

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

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