Find the thing that is the same
about each group. There are the missing number things
in the group.
The question is asking us how many
things there are in each group. Here, we have a group of dogs. We also have a group of balloons, a
group of trees, and a group of cupcakes. How many are in each group?
Let’s count how many dogs there are
in this group: one, two, three, four, five. How many balloons are there? There are five. Let’s count the trees: one, two,
three, four, five. And there are five cupcakes.
Each group has five things in
it. So each group has the same number
of things, five.
