Something is the same about all the stickers in the group. Pick another sticker that belongs in the group.
In this problem, we’re given a group of three stickers. We’re asked to choose one of three possible stickers that belongs in the group. Let’s start by looking at our three stickers that are in the group. What’s the same and what’s different about these stickers? Well, we can see what’s difference straight away. Each sticker shows a picture of a different object. We have a picture of apples, of keys, and dogs.
Each sticker shows a different object. But our problem says that something is the same about all the stickers in the group. What’s the same about the stickers? Let’s count the number of objects on each sticker. How many apples are there? One, two, three. How many keys are there? One, two, three. And we can also see that there are three dogs too. Each sticker shows three objects.
We’re asked to pick another sticker that belongs in the group. So we need to look for another sticker that has three objects on it. Can you see without counting. Maybe you can spot it already. But let’s count each object just to be sure. How many coins are there? One, two. This sticker doesn’t belong in the group because it has two objects on it not three.
How many apples are there? One, two, three, four. There are four apples. If we try to put this sticker into the group, it wouldn’t belong either because they are four objects. And we’re looking for three. The correct sticker must be our final one. Does it have three cars on it? Yes, it contains three objects. And that’s why it belongs in the group. Our group only contains stickers with three objects on them. And that’s why the one that belongs is the one with three cars.
