MathMagic is an email-based collaborative learning
project. Challenges are posted to the list in each of
four categories (grades K-3, 4-6, 7-9, and 10-12). Each
registered team pairs up with another remote team to
engage in a "problem-solving dialog". When an
agreement has been reached, each pair of teams posts one
solution.
