The number pi is never-ending, and so is the fun that students can have learning about this magical number. Here are 11 great educational activities for students in Middle School and High School (grades 6-12).
Students solve geometry problems focused on the circumference and area of a circle to find answers in terms of Pi. As students progress through the Scavenger Hunt, they collect answers in terms of Pi on each of their pieces of a pie (which serves as their answer sheet). The Scavenger Hunt is designed in a way that different groups can progress through the hunt with different starting problems.
