ABSTRACT:
An educational jigsaw puzzle (20) in accordance with a first embodiment of the invention including a plurality of substantially flat components (22) having various beginning members (23, 24). Beginning mathematical expressions (26, 27) located on components (24, 25) are directionally combined with same-component expressions (28, 29), and equivalent expressions (30) are located on components (22) with matching edges. These equivalent expressions (30) are then directionally combined with same-component expressions (32), and new equivalent expressions (30) are located on components (22) with matching edges. The process of combining new equivalent expressions with same-component expressions continues until final equivalent expressions (34) are found. Components (22) not containing mathematical expressions are either blank or contain portions of pictures (38). Guidelines (36) and pictorial representations (40) of mathematical expressions may be contained on numerous components (22).
