Isabelle Glen-Lambert, 7, thought recess was a bummer. A few kids got hurt on the crowded playground at her school in Woodland Hills, California, so the principal made a rule: kids had to earn tags for good behavior to be allowed on the equipment. "It wasn't fair," said Isabelle. She got 31 kids to sign a complaint. The principal agreed to listen to students' suggestions. Now all kids climb the jungle gym, one class at a time. Way to hang in there, Isabelle!
