Who: Our super smart second grade students
When: March 3, 2010 (48 hours - as long as it is March 3 somewhere in the world!)
What: Students play at home against other students around the world in live games of mental arithmetic. Each game lasts for 60 seconds and students can play up to 500 games, earning points for each correct answer. The students who answer the most questions appear in the Hall of Fame. Students cannot select their level but will move up as they progress.
