Victoria has 30 crayons and each box holds five crayons. Find the number of boxes she will need for all the crayons by finishing the bar model. 30 divided by five equals what?

We know that Victoria has 30 crayons altogether. We also know that each box contains five crayons. We have to work out the number of boxes Victoria will need. How many fives are there in 30? What is 30 divided by five? Victoria has started to draw a bar model. Her bar model shows three boxes of five.

To find out how many fives there are in 30, we could count in fives until we reach 30. One five is five. Two fives are 10. Three fives are 15. Four fives are 20. Five fives are 25. And six fives make 30. 30 divided by five equals six. If Victoria has 30 crayons, and each box holds five crayons, she will need six boxes for all the crayons. 30 divided by five equals six.
