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?

Easy

Approx 3 minutes
