September 25th is Math Storytelling Day. Today (every day!) is the perfect opportunity to encourage and nurture the love of mathematics through reading about math. There are many terrific books that include mathematical content or challenging puzzles to solve. Here are some titles that will encourage children to stretch their mathematical muscles in a different way.

The Phantom Tollbooth by Norton Juster - Take a journey with Milo, a young boy who drives through a magic tollbooth into the Lands Beyond and embarks on a quest to rescue the maidens Rhyme and Reason from exile and reconcile the estranged kingdoms of Dictionopolis and Digitopolis. This is a great book for kids enamored of words and/or numbers.

Grandfather Tang's Story: A Tale Told With Tangrams by Ann Tompert and The Warlord's Puzzle by Virginia Pilegard are both stories that revolve around an ancient Chinese puzzle made from a large square cut into seven pieces. The seven shapes include a small square, two small triangles, a medium-sized triangle, two large triangles and a parallelogram. Kids can read the stories and follow along with their own set of tangrams!

The Man Who Counted: A Collection of Mathematical Adventures by Malba Tahan - Orginally published in 1949 as O Homem que Calculava, this book of mathematical puzzles was written by Júlio César de Mello e Souza and published under the pen name Malba Tahan. The book is an enjoyable series of "Arabian nights"-style tales, with each story built around a classic mathematical puzzle. In each tale, Beremiz Samir uses his mathematical powers to "settle disputes, give wise advice, overcome dangerous enemies, and win for himself fame and fortune."

The Puzzling World of Winston Breen by Eric Berlin - Winston sees puzzles everywhere. Imagine his dismay when he gives his sister a box for her birthday, only to learn that it has a secret compartment containing four wood sticks with puzzle clues. Readers will solve puzzles right along with Winston and his sister Katie as they try to solve the mystery. The sequel to this book, The Potato Chip Puzzles, is also highly entertaining.

Books by Theoni Pappas - Written in the same vein as the Brown Paper School Books, Pappas has written many books about math, my favorites of which are those where a cat explores the math in and around his house.

Do the Math: Secrets, Lies, and Algebra by Wendy Lichtman - Tess is an eighth grade girl experiencing typical middle school problems--friends breaking promises, peers cheating on tests, the boy that may-or-may not be interested--as well negotiating some drama at home. Tess examines everything logically and views her world through the lens of mathematics.

"The way Sammy spoke about her mother made me think of what Venn diagrams look like when the two sets have nothing in common--like, for example, the set of odd numbers and the set of even numbers. Their intersection is called an empty set, because there's nothing in it. There's not one number that can be both odd and even. I didn't like thinking of Sammy and her mother like that--like an empty set." (p.49)While the book isn't necessarily about math, Tess has many interesting mathematical insights and how they relate to the world we live in.

That's it for now. Do you have a favorite book that offers something mathematical to puzzle over? If so, please share. I would love to add your ideas to this list.
