Dash and Rudy are fifth-graders at Euclid Elementary. Dash is a mathematician. Rudy is a standout track athlete, but she's also a mathematician (she just doesn't know it yet). When circumstances result in Dash moving next door to Rudy, they discover a common interest in mathematics, and a friendship blooms. The Euclid Police need a mathematician's help when a string of burglaries occurs in a very mysterious pattern. Are Dash and Rudy up to the challenge? Can Dash repair a broken relationship? Can Rudy overcome a mishap on the track? Can guinea pigs swim? Open this book to find the answers to these questions and more! And that's not all! A copy of Dash's math notes is included in the back of the book in case you want to read more about the interesting mathematical curiosities from the story. "It was intriguing to learn that this technique is normally used for architecture, website, and interface designs but can be used for other interests as well; from counting the spirals of a pine cone and the petals of a flower to solving a string of burglaries. It was clever how Seth integrated the Fibonacci math technique into this plot as a way to stimulate young readers' interest in problem-solving through math and reading. To get children more involved with math, Seth has provided Dash's Math Notes at the end of the book to help readers solve the mathematical equations outlined in the book while learning different mathematical terminology. This book is a must for any library and is ideal for adults to learn about the wonderful world of math. Children will enjoy this book." -Reviewed by Vernita Naylor for Readers' Favorite
