School Library Journal Review

Gr 2-5-This series is purported to help children with math skills. Friends from a martial-arts school use easy-to-see clues to solve mysteries. In The Lost Key, the students count shelves, multiply the number of jump ropes and mitts, and subtract the number of pairs of shorts they have to determine what is missing from the school. The math is too simple for the audience that might pick up the books. The artwork is vaguely mangalike but more cartoonish and looks as though it was drawn quickly with spare detail. The stories are thin and dull, and most children will solve the mysteries long before the conclusions.-Carrie Rogers-Whitehead, Kearns Library, UT (c) Copyright 2010.
