[ Editor’s Note: Alex Cook is involved in a “Pi Day Challenge” that involves solving 28 puzzles. Alex sent me the following email which I’m forwarding for your enjoyment. Yes, Pi Day was Sunday but the festivities continue! ]
Hello Fellow Math Enthusiasts!
My name is Alex Cook, and I want to let you know about a project I am working on called the Pi Day Challenge.
First off, this project is not exactly my project - it is a project of Matthew Plummer’s, a high school teacher from Hanover, MA - I am helping with some of the logistics!
Starting in 2003, Matthew Plummer started creating “Puzzles” on the computer for students. The puzzles were math and logic based. These puzzles were compiled together, put on his school’s web site (hanoverschools.org), and then launched on Pi Day (March 14th). The objective was to go through each of the puzzles and make it to the end.

It tells a story . It has pictures , so it engages the visual sense as well as the word processing” sense .
