Group of Two

A group of two means having two things together, like two cookies or two teddy bears. When we group things it means that we put them together so we can count them easily. So when we want to group two things, we just take two of them and put them together. It's like having a buddy or friend to play with, there are two of us instead of one. And having a group of two can be helpful because we can share our things or work together.
