Nickelodeon’s eighth annual Worldwide Day of Play packed the National Mall Sept. 24, as kids of all ages enjoyed fun and active games and learned about how to live healthy lifestyles. During the day, the television network didn’t broadcast any shows to encourage kids to go outside.

The free event attracted hundreds of kids, who wanted to see their favorite celebrities. Victoria Justice, Keke Palmer, Nathan Kress and Jennette McCurdy all attended the festival, and Big Time Rush and the Fresh Beat Band performed.
