Abracadabra and 1-2-3! Amaze your friends and stump your parents with mathematical magic tricks. You don't need magician's equipment to perfect each feat; just practice it a few times. Some will turn you into a mind reader: for example, just ask an audience member to roll some dice and stack them. Then, voila! You'll conjure up the total numbers on the hidden dots and tell everyone. Or, guess a word someone has picked from a dictionary. Want to make a little "Pumpkin Pi?" ("Pi," in algebra, is what you get when you divide the circumference of a circular object by its diameter.) Here, no matter what number someone enters into a calculator, the result is always a "piece of pi." Plus: a little card sorcery, mind-boggling magical things you can do with paper, and many more.

From School Library Journal:
Grades 3-6--Math and magic mix for learning fun in this book of 34 tricks, divided into 6 categories. Each activity is introduced with a brief summary, a list of needed items, and details on preparation, followed by clear, step-by-step directions, which often include black-and-white drawings that clarify and add humor. A section called "The Mathemagical Secret" explains why the trick works. Readers can open this book to any page and find a neat trick that can be performed easily, even if they don't fully understand the math, which may well come with practice. A wonderful resource for supplemental math activities and for recreation.
