Let's use an area model to find the answer to $30\div2$30÷2.
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 |
How much area is remaining?
$10$10 | ||
$2$2 | $20$20 | $\editable{}$ |
Total area: $30$30 |
What is the width of the second rectangle?
$10$10 | $\editable{}$ | |
$2$2 | $20$20 | $10$10 |
Total area: $30$30 |
Using the area model above, what is $30\div2$30÷2?
Let's use an area model to find the answer to $45\div3$45÷3.
Let's use an area model to find the answer to $60\div4$60÷4.
Let's use an area model to find the answer to $60\div5$60÷5.
