Lesson Description:
Discovering Pi is a lesson designed to give students a hands-on experience that will help them truly grasp the concept of
pi. The students use string and a ruler to measure the circumference and diameter of three different circles.
They then calculate the ratio of the circumference to diameter, perhaps not realizing that they are really calculating pi.
Students also read and complete the Pi Basics sheet. Finally, if you celebrate Pi Day on March 14, have students share
pi jokes, pi songs, pi facts, and pi history before EATING PIE. Of course students love this last part!!

Teacher Testimonial:
Pi Day (March 14) was one of the biggest hits with my students last year! We learned about pi, told pi jokes, sang pi
songs (that's a first in my math class!), and learned pi history and other pi facts. Best of all, WE ATE PIE!!
The students learned how to find the circumference and area of a circle. They also learned where pi comes from.
Most importantly, we created a special day to have fun while we were learning. I believe that many of my students will
remember March 14th in a special way from now on.
