Pi Heats Up for the Summer!

The fraction 22/7 is a rough approximation of pi (3.14..) and some schools celebrate "pi day" on July 22, especially in cultures where the date is commonly written with the day first and then the month.  If you are teaching a summer math course you may want to take time out on July 22 to celebrate pi!  (May we suggest ice cream pies to offset the summer heat?).

November 9 is the 314th day of 2008 so now is the time to begin planning for a Fall Semester "pi day" -- have your activities peak at 1:59 in the afternoon (3.14159...).
