Pi Day is March 14. There are many great ways to celebrate this day with your class. One of my favorites is to read "Sir Cumference and The First Round Table" by Cindy Neuschwander to my class. This book truly explains what Pi is, in easy terms for young children to understand.
I created this free math lesson for "Sir Cumference and The First Round Table" as an accompaniment to this book. Students can complete the worksheets in this lesson after reading and discussing the book. Happy Pi Day!
