The Math Mastery Challenges are math questions that you can
complete in your free time to earn rewards. When you have completed the
first 25, you will receive recognition on the yearly Mastery Board. When you
complete 50 you will receive recognition on the lifetime achievement award. You
will also receive a reward at the end of the year if you complete 50 or more
questions.
