Abstract
Abstract The invention relates to an educational device adapted to permit the rapid and simple assembly, disassembly and reassembly of letters, words or figures to facilitate reading. It comprises a planar area (10) of thick paper, cardboard, synthetic plastics or other material which is divided into a number of squares, oblongs or other discrete sub-areas of a desired shape (12 . . . 28) by dividing lines or gaps so that at least some of the discrete sub-areas can be folded over as flaps to cover part of a central area (18, 20, 22) of the planar area, there being letters, words or figures applied to both the front and back surfaces of the planar area, the planar area having corner flaps.

Total Claims: 6
Claim 1
Independent Claim
171 words
An educational device for teaching children to read, said device comprising: (a) a planar area of sheet material having corner zones; (b) dividing lines crossing each other at right angles and serving to divide said planar area into a plurality of discrete rectangular sub-areas, at least one of said sub-areas forming a rectangular central area bounded along edges thereof by rectangular sub-areas adapted to be folded over as flaps to cover at least part of the said central area, and at least some of said dividing lines being in the form of cuts to allow any selected one of said flaps to be folded over without displacing a flap adjacent to it; and (c) printed reading matter comprising letters of the alphabet on both the front and back surfaces of the planar area, but on only one side of each sub-area, each letter of said reading matter being printed in at least two contrasting colours; said sub-areas including at least four corner flaps at the corner zones of said planar area.
