BRYAN EATON/Staff photo. Skye Casella, 15, left, and Kylie Woekel, 16, try to figure out some math problems using Pi to use in a scavenger hunt in Newburyport High School math teacher Tracey Glynn's geometry class. Celebrating "Pi Day", the students did different activities relating to the mathematical formula and then got to eat several pies, apple in front of them, donated by Glynn's friend Katie Habib, a manager at Figtree Kitchen in Newburyport.
