Students participated in festivities to celebrate the mathematical constant π (pi). Pi Day is observed on March 14 due to π being roughly equal to 3.14 (3/14 in American date format). Montessori students study pi each year, with a focus on the discovery of the relationships of the parts of a circle and π, which represents the ratio between a circle’s circumference to its diameter. It is a true sensory experience, visual, hands-on, and even with tasting! The oldest students spend time preparing the lesson during their third year, rehearsing it, and adding in vocabulary, visual aids, and even technology. Since they have received the lesson before, they are demonstrating mastery when they need to understand it well enough to teach it to someone else. 
After the lesson, the students enjoyed sampling many delicious varieties of pies!
