Circle Visualization Exercises
Imagine a circle. Does it have a colour? Does it have a centre?
Make your circle get bigger and bigger. Use your arms to show me how big your circle is.
Now make your circle get as small as possible. Point to where you see it.
Make your circle regular size again. And imagine a second circle. Keep your first circle still and move the second one. Can you make the two circles touch? Can you make your new circle bigger? Now in how many places does it touch your first circle?
