Pi Day is just around the corner. I always try to have fun with my students on this day, around the concept of Pi. Cindy Neuschwander wrote the book “Sir Cumference and The First Round Table” which does a great job of explaining the concept of Pi through an engaging story. I created a Free Lesson For “Sir Cumference and The First Round Table”. After reading the book, and learning about Pi, this lesson will let your students apply and practice what they’ve learned.
