ABSTRACT:
A learning aid permitting the student to insert a worksheet into a rigid body having space between two planes. One of the planes is clear permitting the instructor to mark on it, performing the work required by the underlying worksheet. The instructor's marking is erased and the student attempts the same task. The work sheet is secured in place by a clipboard. The clipboard rides in a slot to prevent scratching of the clear panel member. The clipboard may be secured in the slot by a latch mechanism.
