Hey, question for you: How do you handle the kids in your class that are far smarter than the others in your class, to the point where they've already finished the assignment and may or may not be bothering other kids? I know when I was growing up, my teachers would let me read quietly as long as I finished the assignment.

Doing anything quietly works.  Usually we also have a big project due at the end of the semester that is assigned at the beginning they could work on too.
