On Pi (π) Day, also known as March 14, Middle School math classes participated in schoolwide Pi-oriented activities. The sixth grade and seventh grade classes practiced teamwork, as they, using twine and yardsticks, measured the circumference and diameter of the center circle on our basketball court. Next, they plugged their measurements into the formula, C / D  = Pi (π), in an effort to “prove” Pi. In eighth grade, students shared their own Pi-based activities, posters and presentations. Afterwards, they all celebrated the day by enjoying some tasty, circular treats and watching a three minute and fourteen second video about the origins of Pi.
