Don’t Reinvent the Wheel; Calculate its Circumference: Pi Day Resources
“Students will be able to measure the circumference of a circle with a straight ruler, to the closest one hundredth of a centimeter.”
Think about that exercise. Wouldn’t that be frustrating? Thank goodness for pi (and diameters)! (That said, it could be an interesting way to introduce pi and its use.)
Thanks to ancient math wizards and then Archimedes, we have pi. And since we know you’ll be repping pi (and pie) in some form or fashion on Wednesday, March 14th, we decided to put together a resource guide for math teachers (and those committed to integrating math, or pie, into their curricula).
Lastly, BetterLesson members have shared dozens of great resources for teaching pi, circumference, and everything related. Here are links to the lessons:
Derive Pi (6th Grade) by Kaiulani Ivory
Circumference and Pi (6th Grade) by Jason Armstrong
Pi lab (7th Grade) by Stu Wulsin
What is Pi? (7th Grade) by Nicky Berman
Using Pi to Calculate the Area of a Circle (7th Grade) by Jennifer Wells
Bonus: Fact of the day: pies are only accepted as relevant to pi day because their crusts are round.
