Pi Day is coming! Who’s planning to bake a pie (or buy a pie)? Many of us enjoy this unofficial holiday (March 14 or 3.14, get it?) as an excuse to enjoy pie. Some folks like having a reason to get excited about math. If you are one of those people—or if you don’t get excited about math, you but need to teach or learn math anyway—I have a newer resource to tell you about!

TumbleMath is a newer eResource that is full of books about math! You can read the books (or watch an animated version) and practice what you learn with the quizzes and worksheets provided. Teachers and parents can also find lesson plans with helpful information about how the books match curriculum standards. The “about” page has two guides for using TumbleMath. One is aimed at parents and the other at classroom teachers.

It’s super easy to browse through the available titles. You can also select specific topics to see what books are available on that subject for readers in different grades.

One of the really nice things about TumbleMath is that there are no restrictions on people using the same book at the same time. So if everybody wants to read Sir Cumference And The Dragon Of Pi on Pi Day, you don’t have to worry about all the copies being checked out! (Just so you know, you can also find the Sir Cumference books on hoopla.)

The collection is made up of picture books, but that doesn’t mean all the books are for younger children. There are some graphic novels and books on more advanced topics for students up through fifth grade.
