Overhead projectors allow teachers to display visual materials for an entire classroom to see. They work by projecting transparencies onto a screen using an overhead projector. Transparencies can be hand drawn, printed, or photocopied onto clear acetate sheets. This allows teachers to keep their eyes on students, direct attention to important concepts, and build upon ideas by overlaying multiple transparencies. Overhead projectors provide an easy to use and flexible tool for note taking, lessons, schedules, maps and more in the classroom.
