When Logan’s class takes a trip to a math museum, his mischievous friend Benedict is sure it will be a boring day—until he discovers a robot and its creator in an off-limits area. The robot proves feisty, and soon both boys get zapped. They realize only later that they’d left the museum without their math skills. To get back the knowledge they need for school—not to mention buying food at the mall, divvying up dinner at home, and much more—they’ll have to get back to the museum and pass a series of math challenges. Being “numbed” teaches Logan and Benedict just how useful, and even fun, math can be.

Author: David Lubar

David Lubar has written more than twenty books for young readers, including Hidden Talents, Flip, Invasion of the Road Weenies, Punished, and My Rotten Life. His novels are on reading lists across the country, saving countless students from a close encounter with Madame Bovary. His short stories have appeared in the collections of such respected anthologists as M. Jerry Weiss, Don Gallo, and Michael Cart, and in a variety of magazines, including Boy's Life, READ, and Nickelodeon. He has also designed and programmed many video games, but he'd much rather spend his time writing books and hanging out with librarians. He lives in Nazareth, Pennsylvania, with his wife and a variety of cats.

“Lubar uses humor effectively throughout the book, but he also builds dramatic tension as the boys race against the clock to regain their skills through math-oriented challenges.” —Booklist Online

Kirkus Reviews

“The tests the boys have to pass are enjoyable and entertaining, stretching readers’ brains and reinforcing the power of math. Teachers will enjoy reading this aloud and challenging their students….The sum of the parts is greater than the whole here, which is probably exactly the point.” —Kirkus Reviews

School Library Journal

“Lubar’s integration of mathematical concepts, such as the Mobius loop and probability, simultaneously teaches and entertains….This book will delight teachers and students alike with its wide appeal, zany humor, and vast potential for use in classrooms.” —School Library Journal
