Students participated in special PI Day activities, celebrated the day by singing PI Day songs, and (of course) the traditional  eating of the pies. 

The "Joy of Pi" website will tell you everything you ever wanted to know about pi.  Check out the "pi facts and figures" link, and the 10,000 digits of pi page. 

Investigate the Pi Across America website for even more interesting pi activities!

Algebra II class measured circular objects to calculate an experimental best-fit line for the circumference/diameter relationship.  The relationship was found to be
 C = 3.13 D - 0.01   (with a correlation coefficient > 0.999)

Of course, students also consumed apple pie.  (Pie ARE squared!)
