**Pi Day Resources**

Note - a number of these ideas and the wording for some of the directions come from the Pi Day information page from the Exploratorium: http://www.exploratorium.edu/pi/pi_activities/

**Digits of Pi Memorization **

**Buffon's Needle - **

Materials needed are an appropriately lined sheet of paper (large), toothpicks, multiple yardsticks or meter sticks, and a calculator.

**Seeing Pi**

Materials needed are a can of tennis balls and a tape measure

**Finding Pi**

Materials needed** **are a number of circular objects (lids, hula hoop, Frisbee, etc.), lengths of string (at least as long as the longest circumference), yard sticks (or, better yet, meter sticks)

**Making Pi**

Materials needed are many strips of each of 10 colors of paper to make a paper chain. Each link is to represent a digit of pi based on it's color. A stapler is also needed for connecting the links.
