Label file folders with the names of each student in your class. Keep the folders organized alphabetically near the classroom door, and whenever you have papers to hand back to your students, place the papers in the appropriate folder for each student. When students come to class, they can pick up their folder so that you don't have to waste valuable class time shuffling papers. Students can turn papers in using a similar system-place a basket or other receptacle near the door, and have students place homework and other papers in the basket as they leave the classroom.
