Pi Day

Today is one of my favorite instructional days, Pi Day.  The concept of pi existing as a geometric ratio in its purest form, and that any numeric representation of pi is an approximation of its true value can be tricky for students to grasp. There are so many fun activities that can be done with students today to explore and learn about pi.

One of the more interesting activities that I've seen done with pi was this musician's interpretation, where he converted numbers to notes to create a beautiful musical composition.  Enjoy Pi Day!

UPDATE: I found some exciting Pi Day logic puzzles at Pi Day Challenge.  Playing requires either a Facebook login or account creation.  The puzzles are challenging and fun!
