This post has Pi Day free printables, which is each March 14th, of course. Does your school celebrate? Do the teachers share pie in the break room?

The wristbands are included in the Sir Cumference printable, below.  I have combined it with the rest of my printables for this special day.

Sir Cumference and the Dragon of Pi is the best book to read on March 14 each and every year, of course. The stories in the Sir Cumference series are widely used in upper-grade classrooms to help anchor math concepts.

Sir Cumference and the Dragon of Pi, a Math Adventure

by Cindy Neuschwander, illustrated by Wayne Geehan

In Sir Cumference and the Dragon of Pi, a Math Adventure, Radius (the name is referred to but not described in math terms) saves his father’s life after accidentally turning him into a fire-breathing dragon.  Of course, a math formula is the reason for the solution.  Did you know Sir Cumference named Pi in this story?  Did you know this story tells how the math formula for ∏ was discovered?  This is a fictional story but the author’s purpose is achieved when children remember this math lesson.

The Great Knight of Angleland math story by the same author includes a magic medallion just like the one Radius uses in the story to solve math problems in his quest to find King Lell.  Upon achieving his mission, he is knighted as Sir Cumference.

The medallion in the back of this book is made of cardboard and is not actually the real family heirloom used in the book, but it solves math problems just the same.  Of course, it is really a protractor.

The clever wording in this story such as the “Pair of Lells” (two dragons flying in straight lines next to each other) explains the fictional origin of the math words like parallels.  Very fun and worth reading!
