Complete the following. There are more what than
dogs?
We’re shown a picture that
shows three groups of animals, all jumbled up. There’s a group of cats, a
group of dogs, and a group of ducks. And the question asks us to
compare these groups together. We need to complete the
sentence. There are more what than
dogs? So to find the answer, we need
to compare the number of cats with dogs and also the number of ducks with
dogs.
One of these groups of animals
will be larger than the group of dogs. But which one? Now this is a picture of cats
and dogs and ducks, and we can’t move them and put them in a line to compare
them or match them up. But what we could do is use
maths equipment to help us.
First of all, let’s model the
number of dogs that there are by using cubes. We can start off by putting a
cube next to each dog, one cube for one dog. Now let’s put all our cubes
together, and we’ll count them as we do this. One, two, three. There are three dogs. Now let’s compare the ducks
with the dogs. Are there more ducks than
dogs? First, we can match one cube
with one duck. Now let’s count them. One, two. There are two ducks in the
picture.
Now if we compare our two lines
of cubes, we can see that there are more dogs than ducks. So can we say that there are
more ducks than dogs? No we can’t. Let’s try the cats, a cube for
each cat to help us model how many there are. Now let’s count them. One, two, three, four. There are four cats.
Let’s compare then the number
of cats to dogs. Can we say that there are more
cats than dogs? Yes, we can. We can see that the line of
cubes that we’ve made is longer for cats than it is for dogs. And we can also see this in the
picture. If we match up one cat with one
dog, we’ve got an extra cat left over. There are more cats than
dogs.
