Math Caper is a computer game that bridges the gap between school math and realistic applications. Typical word problems are unrealistic and encourage students to learn special "math class rules" for solving them. Typical math games pose arbitrary exercises that have nothing to do with the game narrative. Math Caper solves these problems by embedding math in the game world and narrative. The game offers kid-friendly mysteries that can only be solved by realistic problem solving and thoughtful application of math. Let's stop teaching kids to solve math problems, and start teaching them to solve problems with math.
