For a challenge, try this Pi Day sudoku puzzle. The rules are a little different from standard Sudoku, in part because the blocks are jigsaw pieces rather than 3×3, and in part because the first 12 digits of π are used instead of the standard 1-9.
The Pi Episode: Math Bites with Danica McKellar. This would be a great video to show on Pi Day, March 14th. It is about 6 minutes long and entertaining and it also stars Winnie Cooper (I mean Danica McKellar). Make Middle School Math Pi Day an event at your school.
Celebrate Pi Day with Learning Activities @Education Possible Even if you or your kids aren’t self-described math geeks, with these hands-on activities, you can still have fun honoring this constant ratio between a circle’s circumference and its diameter.
