Both introductory and advanced CS classes can learn a great deal from grappling with the simple challenge of calculating the circumference of a circle from its diameter. In this session we describe three different ways to calculate pi and how they employ different CS and math concepts. At an introductory level, Pi can be calculated in a very visual way using a “Monte Carlo” method. At an advanced level, we demonstrate how Pi can be calculated using multiple CPU cores on a single chromebook or any other web-capable device. These free activities were developed by the STEMcoding project (http://youtube.com/STEMcoding).
