Isabella had 30 flowers to put into vases. She found the number of vases she needed by solving 30 divided by 10. How many flowers did she put in each vase? And how many vases did she need?

This problem gets us to think about the calculation that Isabella uses to find out the number of vases she needs. She works out 30 divided by 10. What is each of the numbers in this calculation mean? What does the 30 represent? What does the 10 represent? And what is the answer?

We know that the first number 30 is the total number of flowers that Isabella has. This is the amount that’s being split up in the division. We’re told that she uses a division to find the number of vases she needs.

And so the unknown answer to the division is the number of vases. This means we know that the number 10 in the division is the number of flowers in each vase. It’s like saying 30 split into groups of 10, how many groups? 30 flowers split into vases that contain 10, how many vases?

So our first question asks “How many flowers did she put in each vase?” We’ve answered this already. 30 flowers were split into groups of 10. There were 10 flowers in each vase.

And so our second question asks “How many vases did she need?” In other words, what is the answer to the division. We can use our knowledge of multiplication facts to help us here. How many tens make 30? How many vases with 10 flowers in each will make 30 flowers? Three multiplied by 10 equals 30. So we can say 30 divided by 10 equals three.

30 flowers split into groups of 10 equals three groups. Isabella needed three vases.
