Print In Brandi Krepps’ classroom Wednesday morning, students were bouncing in their seats as they raced through lessons with their study groups. “It’s awesome,” sixth-grader Preston Hamilton, 12, said. “It’s lit. It’s fun and exciting.” If you didn’t guess that this was a math class, that’s understandable.
