Chloe has seven dolls. She puts her dolls into two boxes. Complete the following sentence. There are three dolls in one box and what dolls in the other. Are there four, three, or five?

In this question, we’re told that Chloe has seven dolls and she puts her dolls into two boxes. We’re also told that there are three dolls in one box, but we’re not told how many dolls are in the other. We have to choose from three possible answers. Are there four dolls in the other box, three, or five? Let’s use a part–whole model to help us think about the problem.

We know Chloe has seven dolls and there are three in one box, and we’re trying to work out how many dolls there are in the other box. Let’s use the picture of the seven dolls to help us. We can cross out the three dolls that Chloe has already put away in a box. Then we can count the number of dolls that are left. There’s one, two, three, four. Now we can complete the sentence. There are three dolls in one box and four dolls in the other. The missing number is four.
