When we were in school, fighting childhood obesity meant running in circles during P.E. These days, kids have it a lot easier, thanks to Konami's new DanceDanceRevolution: Classroom Edition.

Teaming up with UnitedHealthcare, Konami has designed a new DanceDanceRevolution game specifically for use at school. The "exergame," as Konami called it in a press release sent out this week, debuted at CES and has launched in three schools in Florida, Georgia and Texas. Up to 48 students can play at once. We assume the 49th student in big classrooms has to run in circles around a field instead.

Did your school have any fun P.E. activities? How about video games?
