Holes (paperback)

Fifth grade is off to a terrible start for the Math Kids. Jordan and Justin are in a different class from Stephanie and Catherine. Worse, they have Miller the Killer for math, and he hates math! Even more troubling, Jordan witnesses Robbie, the class bully, in an angry confrontation with his father and wonders if Constable Colson might be doing more than yelling. People problems suddenly seem a lot more challenging than homework, but maybe with the right plan--and some math--the four Math Kids can find a way to deal with their classroom woes and make sure Robbie stays safe. The Math Kids: An Incorrect Solution is the fifth book in the Math Kids series.
