A Pi Day Math Activity! #Pi #π

Not only is it Pi Day, but it is 3/14/15. In Math Terms that is 3.1415. If you want to get really geeky at 9:26 it will be 3.1415926 or π. This week I was invited to watch a math Lesson where students measured the circumference and diameter of objects: A Quarter, Cup, Plate, Bike Tire and several other objects. Then, students entered their information on a class Google Sheet. Pi is the ratio of the circumference of a circle to its diameter Circumfrance of a circle divided by diamater = π.  The Google Sheet calculated Pi, the better the students measured, the closer to 3.14 they got.
