Do the Math #2: The Writing on the Wall
Grade 5&ndash;9&mdash;This sequel toDo the Math: Secrets, Lies, and Algebra(HarperCollins, 2007) picks up the story of Tess, an eighth grader who copes with uncertain situations and unpredictable people by applying mathematical equations or symbols, an approach that gives her comfort and perspective. After seeing a series of numbers graffitied on a building near school, Tess recognizes that it is a math puzzle and solves it to reveal a secret code. When she decodes the word "arson," she realizes that someone is trying to communicate shocking information to her (there has recently been an unexplained fire at school). Though aware of the punishment for defacing property, she writes her own message on the wall in an attempt to get more information. She eventually solves the mystery, but ends up getting more than she bargained for when she is caught and must face the consequences. She also wrestles with peer relationships as she deals with a boy who is tormenting her and tries to figure out contradictions in a new friend. Lichtman cleverly incorporates mathematical concepts into Tess's narrative, keeping the ideas simple and explaining them in terms that readers can understand. Tess is likable and navigates through her problems in a realistic manner.&mdash;Amelia Jenkins, Juneau Public Library, AKCopyright &copy; Reed Business Information, a division of Reed Elsevier Inc.
