NZ Level 3 Divide a 2 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 $30\div2$30÷​2.

a

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

 $2$2 Total area: $30$30

Now if we don't know straight away what $30\div2$30÷​2 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 $2$2.

 $10$10 $2$2 $\editable{}$ Total area: $30$30
b

How much area is remaining?

 $10$10 $2$2 $20$20 $\editable{}$ Total area: $30$30
c

What is the width of the second rectangle?

 $10$10 $\editable{}$ $2$2 $20$20 $10$10 Total area: $30$30
d

Using the area model above, what is $30\div2$30÷​2?
