ABSTRACT:
An educational device that makes printed material, in the form of a child's workbook of varying thickness in the open reading position, or sheet material in the form of a worksheet, or blank template reusable. Children view their work through the clear transparent cover of the apparatus and record answers using a dry erase marker or wipe-off crayon. When completed, answers easily wipe away, allowing for exercises to be repeated many times until mastery. Additionally, the device is convenient, quick, simple, and easy to utilize, especially for young children. It is easily transportable and has multiple functionality, including an additional work, therapeutic, play, or display surface.
