Two very special circles are on the floor:
2circles1
Very special because they can get bigger or smaller - as you like.
So you might like them to be like this:
changed
Maybe you like things small - so you would have:
change2
I'd like the blue one to grow:
Red-In-Blue
Whoa! That looks different.
The Red is inside the Blue.

So the Red and the Blue can grow - just as you like.

TOUCHING?

OVERLAPPING?

OUTSIDE?

Have a go. Send us some pictures of what you do - we'd love to see them.
