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.
Claims10
An educational device comprising:
- a frame means having a substantially rigid, flat top surface;
- a plurality of opaque base sheets wherein each base sheet has indicia on a top surface thereof and wherein at least two of said base sheets have indicia on their top surfaces that provide related information;
- a plurality of transparent sheets wherein each sheet has a surface capable of being marked upon;
- and
- a registration means operatively connected to said frame means for removably securing to said frame means in a stacked manner and in a fixed registry at least one base sheet and at least two transparent sheets wherein said at least one base sheet is located atop the top surface of said frame means and wherein at least two transparent sheets are located atop the base sheet.

A method of learning comprising:
- placing a first opaque base sheet in fixed registry onto a top surface of a frame wherein said first base sheet has a first predetermined pattern on a top surface thereof;
- placing a first transparent sheet on top of and in fixed registry with said first base sheet;
- tracing the pattern shown on said first base sheet onto a top surface of said transparent sheet using a marking means;
- removing said first transparent sheet from the frame;
- placing a second opaque base sheet onto the frame wherein said second base sheet has a second predetermined pattern on a top surface thereof and wherein the second predetermined pattern is different from the first predetermined pattern;
- placing said first transparent sheet onto the frame whereby it is located on top of the second base sheet;
- placing a second transparent sheet onto the frame on top of said first transparent sheet;
- and
- marking a pattern onto a top surface of said second transparent sheet.

An educational device comprising:
- a frame means having a substantially rigid, flat top surface;
- a first base sheet having a first preprinted pattern located on a top surface thereof;
- a second base sheet having a second preprinted pattern located on a top surface thereof and wherein the first of said preprinted patterns is different in appearance from the second of said patterns;
- a first transparent sheet having upon a top surface thereof an erasable copy of the first pattern, said copy having been made by the user;
- a second transparent sheet having upon a top surface thereof an erasable copy of the second pattern, said copy having been made by the user;
- and
- a registration means operatively connected to said frame means for removably securing to said frame means in a stacked manner and in a fixed registry at least said second base sheet and at least two transparent sheets wherein said first and second transparent sheets are located atop the second base sheet.
