Celebrating Pi Day
A few days before her sister celebrated St. Patrick’s Day, Zoe’s class got into Pi Day. As described in the school newsletter:
Students in third grade used Pi Day as a segue into their new Singapore math unit on geometry. In pairs, third graders measured various-sized circles using string. Through this activity, students discovered that regardless of the size of the circle, the ratio of the circumference to the diameter was always approximately 3.14. “As we tallied up our result [of the circle-measuring activity], students were excited to see who came closest to 3.14 with their measurement of the various circles,” says teacher Lori Galante. “One group actually got 3.145!”
