March 14, 2012…. Pi Day Celebration!

The third and fourth grade looping classrooms of Robin Hughes and Sara Barend from Fisher School celebrated Pi Day on March 14.  In any circle big or small, if you take the circumference, and divide it by the diameter, you get an answer of about 3.14. We call that value pi (the Greek letter).  The date of March 14 (3/14) is set aside every year by mathematicians to celebrate this irrational number.

The third and fourth grade students celebrated this math holiday with many different activities.  They made pi bracelets, with each color representing a different digit in the first 24 digits of pi.  They also constructed and decorated circles with various diameters and then computed the circles' circumferences using pi.  A very large paper chain, representing the first 400 numbers of pi was constructed and then displayed in the auditorium, stretching three-fourths of the way around the room.  Everyone enjoyed the story of Sir Cumference and the Dragon of Pi while eating "circular" snacks brought from home.  Finally, at day's end a math song was sung celebrating pi and its value to our mathematical world.
