We can sort different objects into groups.
For example, these objects have been sorted into two categories (groups). All the objects with straight sides are put together. All the objects with curved sides are put together.
We can say there are 3 objects with straight sides and there are 4 objects with curved sides.
Now, let us sort these animals by number of legs.
How many groups can we make?
How many animals are there with 4 legs?
Look at the pictures shown.
