Friday, March 14 was Pi Day (3.14). What better excuse is there to have a celebration of math with middle schoolers than π? About three hundred fifty students, parents, teachers, and volunteers from the high school, PTA and community, celebrated π at the East Somerville Community School (ESCS) by eating pizza for dinner, then spending an evening estimating, creating, collecting data, answering questions, and ending with pies for everyone and π pencils for the students.

After enjoying pizza donated by the Bickoff family (discounted by White Sport), the students from East Somerville, who were joined by students from Healey, Argenziano, West Somerville, Brown and Kennedy schools went around to a wide variety of math activities set up in the halls, foyers and auditorium. These activities included: bicycle wheel roll, guessing contest, tooth pick drop (Buffon Needle problem), drawing a circle the size of a CD, mystery boxes, π button design, π facts quiz, birthday in π, circle in square vs square in circle, drawing cardiod or nephroid, drawing concentric circles by folding, drawing circles by tangents, drawing circle by right angles, reciting digits of π, predicting how high of a pour, predicting circumferences and radii, graphing circumference vs diameter.

The event was planned by Scott Weaver (ESCS), Wil Jacques (Healey), Erica Voolich (Somerville Mathematics Fund) and Lindsay Garofalo (ESCS). Table Talk Pies of Worcester generously supplied small pies for all who came that night and large pies for winners of events. Table Talk has generously supported this Somerville Math Fund event for eleven years. Star Market/Shaws (Beacon Street) generously donated most of the juice.

Pi Night was sponsored by the Somerville Mathematics Fund. This year, East Somerville students returned to their rebuilt ESCS building after their long hiatus after the fire which had destroyed their school building. It seemed appropriate for π night to also return to the ESCS building— the location of the original Somerville Math Fund Pi Night in 2003, planned by Wil Jacques, Mary McClelland, Colleen Murphy and Erica Voolich.

When planning the first SMF π Night, the Math Fund called the Table Talk Pi Company and explained what π day was and Table Talk generously donated large pies for prizes and small pies for everyone. Eleven years later, Table Talk Pies is not only still donating to the the Somerville Pi night celebration, but to many more. In fact, this year Table Talk donated 43,000 pies to schools celebrating pi day.

Students put "Happy π Day from Table Talk" stickers on the pies before the π night celebration. |

A big thank you to all the volunteers and donors who made this fun, educational evening possible. It takes a community to celebrate π day!

They were founded in 2000 with the mission to celebrate and encourage mathematics achievement in Somerville MA. In April they will be looking for applications for college mathematics scholarships.
