Kentucky Educational Television (KET) and PBS LearningMedia is offering several resources for teachers to use on Pi Day, March 14. Pi is the ratio of a circle’s circumference to its diameter. Visit KET’s website to access a video that introduces your students to pi and the history behind it, as well as these resources:
- Knights of Pi (for grades 5-8) – Battle dragons and solve problems as you explore the kingdom. This interactive game focuses on geometric reasoning, with special focus on angles, triangles, and circles.
- Pi & The Fibonacci Sequence (for grades 6-12) – Explore intriguing appearances of pi and the Fibonacci sequence outside of mathematics. Although well-known in mathematics, the numbers of the Fibonacci sequence are also frequently found in the natural world, such as in the number of petals on flowers and the number of spirals of a pine cone.
- Calculating Pi with Darts (for grades 6-12) – Pi can be calculated using a random sample of darts thrown at a square and circle target. The problem with this method lies in attempting to throw “randomly.” This video shows how to do it.
