Are there more animals in group
A?
In this question, we can see two
groups of animals. These are labelled A and B. Now, we need to compare these two
groups together because we’re asked, are there more animals in group A? We can find out the answer by
matching the animals in group A with those in group B. Now, we can see just by looking at
each group that some of the animals are the same. But when we talk about matching
objects — in this case, we’re matching animals — we’re not talking about looking for
the same animals. We just need to count the number of
animals in each group. So it doesn’t matter that there’s a
duck in group A and there’s also one in group B. We just need to count the whole
group.
Now, to be able to match up these
animals together, it would be helpful if they were standing in a line one above
another. But, of course, we can see in the
picture that they’re not. Let’s use maths equipment to help
us here. We could start by putting a counter
next to each animal in group A, one counter for one animal. Each counter represents an
animal. Now, let’s do exactly the same with
group B, again one counter for one animal. Now, although we can’t move our
animals around, we can move our counters.
Let’s move one counter at a time
from each group. And we’re going to count as we do
so to see how many animals there are in each group and to be able to match up these
animals. One, two, three, four — can you see
what’s going to happen here? — five. We’ve matched up five pairs of
counters. But we can’t match up anymore. We’ve used all the counters in
group B. So we know there must be five
animals in group B. But we can see that there’s another
animal and another counter left in group A. There are not five but six animals
in group A. We can see that the line of
counters for group A is longer than the line for group B. So we can say group A is a larger
group than group B. Are there more animals in group
A? Yes, there are.
