Pi Day - Preparing for Review of Radius, Diameter, and Circumference

Somewhere in the world, the tau supporters are shaking their heads. Today, March 14th, is the official Pi Day: a celebration of all things 3.14. I am fascinated by one of the world's most famous irrational numbers. When teaching students about pi and its connection to circumference, its easy to slice and dice circles into a shape almost everyone knows: a piece of pie. That being said, students still struggle with understanding some of the nuances of pi and circumference, particularly when it comes to finding radius or diameter when given pi. As we prepare to begin review for state standardized testing, I use short review sheets students can glue into their math interactive notebooks. They use the review sheet as a guide when we complete problems or use math stations in class. I create them even though students have previously taken notes on the subject. They seem to connect with seeing the material in a different format, and it helps them focus on the review and retain aspects so crucial to test preparation. I'm curious about how other educators get students ready during testing season.
