ABSTRACT:
An educational training device in which a plurality of transparent sheets and base sheets are secured in fixed registry onto a top surface of a frame. A student can trace patterns shown on the base sheets onto the transparent sheets. The student can also remove and/or rearrange any of the sheets to thereby study the different interrelationships between the patterns. In addition, a top transparent sheet can be marked upon to draw a pattern that is extrapolated from the data provided by the underlying sheets.
