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.
