Discover the many places where mathematical ideas are surprisingly hidden.

Math can show up in the most unlikely places! When the schools in JeremyÕs town ban math, all the kids cheer, all except his friend Sam, a self-proclaimed mathnik, who sets out to prove that math is not only important, but fun. Running parallel to the fictional narrative are informative sidebars that discuss the weird, puzzling, and amusing aspects of mathematics. Some topics covered are math in nature, art, music, magic and tricks, crime solving, and sports.

Artist Lil Crump brings the pages to life with her lively cartoons, while photographs illustrate key concepts. The dynamic layout invites even math-phobic readers to dive in.

Written for 9-12 year olds, this book uses photographs, illustrations, sidebars, biographies of mathematicians, and DIY activities to highlight the surprising ways math is integral to our lives.
