'a breezy, enjoyable middle grade mystery that pulls off the difficult feat of being both educational and entertaining.' Foreword Clarion Reviews

Fifth grade could not have a worse start for the Math Kids. Jordan, Justin, Stephanie, and Catherine have been split up. The girls are in one class with most of the bullies, which is proving to be chaotic. Meanwhile, the boys are stuck with their nemesis, Robbie Colson, and their new teacher, Mr. Miller, who makes it clear he doesn't like math. Separated like this, the kids worry this could be the end of their math club. And, to complicate matters, there's something going on with Robbie. When Jordan witnesses a shouting match between Robbie and his dad after school, he begins to question the bully's history of injuries and wonders if Officer Colson might do more than yell.

People problems suddenly seem a lot more challenging than homework, but maybe with the right plan—and some math—the Math Kids can deal with their classroom woes and make sure Robbie stays safe.
