Math Classroom Challenge is an educational first-person game that uses a water hose mechanic for players to interact with numbers and solve mathematical problems. It is the children's version of Math Combat Challenge. The game is designed for ages four and up, allowing players to learn numbers, practice aiming water, and solve static and dynamic math panels.

Problems are configurable, ranging in complexity from simple sums to equations, and are presented randomly. The game emphasizes a non-punitive environment, with a parameterizable timer and error counting for dynamic panels. Flying dragons can be used to reduce errors, though excessive use may yield unintended consequences.
