Today’s Special: Pi

Do you know what day Saturday is? It’s Pi Day!

Pi Day is a special holiday (at least for math lovers) that occurs on March 14th to celebrate the never ending fun and mystery of the notorious, irrational constant known as Pi. A constant calculated by dividing the circumference of a circle by its diameter. But, most often, we use the number 3.14 (or 22/7) for the value of Pi.

So what does Pi have to do with books?

Well, there’s a fun children’s series—the Sir Cumference series—that uses King Arthur and the Knights of the Round Table to introduce kids to Pi and other math concepts. Enchanting and lively illustrations add just enough silliness to each problem solving story to make it a great choice for Pi Day fun with elementary-aged students. (View the complete series on the publisher’s website, or read more reviews on Amazon.)

There’s also a style of writing that sequentially matches the length of each word to the digits of Pi. It’s called Pilish. It’s been used to create poetry, and this one book… Not A Wake by Mike Keith. (This book is a new discovery for me, so I haven’t read it. Yet.)

Students 12 and up might enjoy learning about Pilish and even writing a Pilish poem of their own.

Last, but not least, there’s the Life of Pi by Yann Martel. It’s a powerful story about life and survival. I’ve only seen the movie, but it made a lasting impression. (View the movie reviews and content ratings on
