Thursday, March 14 is Pi Day (3.14). What better excuse is there to have a celebration of math with middle schoolers than π? On Pi Day, well over 250 students, parents, teachers, and volunteers from the high school, PTA and community celebrated π at the Healey School by eating pizza for dinner then spending an evening estimating, creating, collecting data, answering questions, and ending with pies for everyone.

After enjoying pizza donated by the Bickoff family of the Commercial Cleaning Service (discounted by White Sport), the students from the students from the Healey School, who were joined by students from East Somerville, Argenziano, Winter Hill and Kennedy Schools, went around to a wide variety of math activities set up in the gym.

These activities included: bicycle wheel roll, guessing contest, tooth pick drop (Buffon’s 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 cardioid or nephroid, drawing concentric circles by folding, drawing circles by tangents, drawing circle by right angles, graphing circumference vs diameter, and predicting circumferences in mm by feel of objects in mystery boxes.

The event was planned by Wil Jacques (Healey), Scott Weaver (ESCS), Jen Rodriguez (Argenziano) and Erica Voolich (Somerville Mathematics Fund). Teachers at the Somerville High School recruited volunteers to help run the events they may have experienced themselves years before. Some members of the Delta Tau Delta (Tufts) chapter joined community volunteers.

Table Talk Pies of Worcester generously supplied small pies for all who came that night and large pies for the winners of events. Table Talk has generously supported this Somerville Math Fund event for fifteen years.

When planning the first SMF π Night in 2003; 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.

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!
