Pi Day 03.14.14

Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.
Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.
Tomorrow the students will celebrate 3-14, or PI day by listening to PI day songs, competing in a hula hoop contest, eating round food, and analyzing the gloriously irrational number pi through an activity called “The Pi is Right”.  See for further information about Pi and the global celebration!  Extra credit is available for students who memorize the first 31 digits of pi (pi day pencils with the number were passed out last Friday when we graphed the relationship between circumference and diameter) and/or bring in round food to feed 15 students in their class.  At the end of the day, extra donations will be given to an area organizations (if there is any food remaining). 

For homework, students will have to develop a pi day poem, song, rap, comic strip, or picture that includes 3 facts they learned about Pi this week.  (Due March 18)
