MATHCOUNTS Minis

 

MATHCOUNTS has been working with Art of Problem Solving's Richard Rusczyk to create detailed web videos focusing on actual MATHCOUNTS problems.  The MATHCOUNTS Minis will focus on at least one MATHCOUNTS problem and associated concepts. Each Mini will also feature an activity sheet to complement the discussed concepts. Every month MATHCOUNTS and Art of Problem Solving will feature a new video and archive the old.
