Pi is a never ending irrational and transcendental number which has been fascinating people for thousands of years. 3.14 is just the start, and after that the number goes on forever. Living books are an excellent way to make school more exciting both for homeschoolers and for children attending school. Reading books about a subject adds excitement and can help take a subject like math from being a drudgery to being a passion.

## Books about Pi for Kids

This book is designed to help you memorize the first 600 digits of pi, which sounds like a formidable task. The book uses a PAO (Person Action Object) system to help you memorize far more digits than you ever though possible. This book would be fine for children or adults and is designed for anyone who wants to learn how to memorize numbers.

## Books about Pi for Adults

### Pi: A Biography of the World’s Most Mysterious Number

* by Alfred S. Posamentier and Ingmar Lehmann *

This book tracks the history of pi from pre-historic times until the present day. It is well written and it is quite accessible to all readers, so even if your math studies ended in high school you will be able to enjoy this book.

### The Joy of Pi

* by David Blatner *

This book is a classic, and includes lots of anecdotes about pi and its history. This book has a light hearted tone and includes a bunch of quirky facts about pi along with pop culture references and jokes. It doesn’t take an extensive math background to read and enjoy this book.

### A History of Pi

*by Petr Beckmann*

This book combines the history of pi with the history of civilization and shows how the two intertwine. It has a lot of diversions and asides and explains how different societies viewed pi and what we can learn about those societies from their understanding of the number. All in all it is a strange combination of math and history.

### Not A Wake: A dream embodying (pi)’s digits fully for 10000 decimals

*by Michael Keith *

This book is a unique collection of poetry, stories, puzzles and lots of other literary forms. It is designed so each story or poem is constructed by using words in which the number of letters follows the sequence of pi. This is very strange concept for a book, and I think most people will either love it or hate it!

### How to Bake Pi: An Edible Exploration

*by Eugenia Cheng*

This is a fun and interesting book that explains math using baking concepts, making it accessible to a wide audience. It is less about the number pi and more about category theory, which is a formalized mathematical structure. This book is more about math and less about history than the preceding books.

### The Irrationals: A Story of the Numbers You Can Count On

* by Julian Havil *

This is a book about all irrational numbers, not just pi. It includes a number of proofs, so it probably doesn’t have as much mass appeal as some of the books above, but it is fascinating and perfect for someone who loves math!
