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 | ||
