Show off your math skills and solve a crime at the same time. On this website designed for middle school students, new unique crimes can be solved every month by answering math questions to get to the bottom of what happened. For every question answered correctly, a new clue is revealed until the criminal's identity is discovered. Each time a crime is solved, $0.10 will be donated to The MATHCOUNTS Foundation, a non-profit that reaches students in grades 6-8 with extracurricular math programs.
