When your art students are finished early with a project, do you let them do free choice drawings? Do you give them a new topic to draw? Something else? It bothers me when a student will finish early and I'll tell them to do a free choice drawing and next thing I know they are wasting the drawing paper with basically scribble or tic tac toe. Most don't, but there's always some. Do you have guidelines for what you allow them to draw in their "free-time"?
