In an effort to promote math education in the US, Nintendo has partnered with nonprofit org Mathcounts to challenge middle school math clubs across the country to up their membership numbers for a chance to win Nintendo DS handhelds and copies of the Personal Trainer: Math title.

Between now and March 25, Mathcounts will randomly choose four schools with at least a dozen participating students in its Club Programs to each receive 20 DS units and an equal number of copies of the game.

The game encompasses more than 40 math exercises from basic addition to extensive multiplication, where up to 16 players with a DS can participate simultaneously in a wireless race to solve equations.

Mathcounts, a national enrichment, coaching and competition program, promotes the subject at more than 48,000 middle schools in the US. For more info on the program and the organization, check out www.mathcounts.org.
