Pi (π) Draw a circle with a diameter (all the way across the circle) of 1
Then the circumference (all the way around the circle) is 3.14159265... a number known as Pi. Pi (pronounced like "pie") is often written using the greek symbol π
The circumference divided by the diameter of a circle is always π, no matter how large or small the circle is!

While playing with your math...eat blackberry pie...at your desk...while the 'people in command walk by and bark "Stop eating at your station" ..raise your eyebrows & politely reply, "Do you like see food? Then open your mouth FULL of pie". Childish? ABSOLUTELY. :)
Remember...ALL of Life is full of laughter and 'childish bits' that dont hurt anyone. DONT GROW UP...it's a TRAP :)
