DESCRIPTION:
BRIEF SUMMARY
This invention relates to an educational device adapted to permit the rapid and simple assembly, disassembly and reassembly of letters, words and figures. It is especially useful as an elementary reading aid.
British Pat. No. 1,536,616 in the name of C. E. High describes puzzle apparatus comprising a substantially square base playing area onto which can be folded strip members which are hinged to the four sides of the square. These strip members are of varied shape and have coloured portions formed on them.
The present invention departs from High's device in that it is concerned with an educational device (primarily for use in teaching elementary reading) and not with a puzzle, and has hinged flaps on which letters, words or figures are printed or otherwise formed. Further, the present invention makes use of the flaps in their unfolded state and not only when they are folded over as in High's device. Yet another distinction is that the present invention makes use of corner flaps which are entirely absent in High's device.
According to the invention, an educational device for the purpose indicated above comprises a planar area 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 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 of the planar area, characterized in that letters, words or figures are printed or carried on both the front and back surfaces of the planar area and that the planar area includes corner flaps.
Preferably more than one colour is used for each letter, word or figure printed or carried on the front and back surfaces of the planar sheet, and different colours are used for the different letters, words or figures on the planar sheet.
In one form of device in accordance with the invention the above-mentioned flaps fold inwards to cover part of the central area and fold outwards to uncover part of the central area. The letters, words or figures applied to the back of the planar area are upside down in relation to the letters, words or figures applied to the front surface of the planar area. It thus follows that, by simply folding the flaps inwards or outwards, individual letters, words or figures on the back surface can be revealed and changed with each other and with those on the front surface.
Among the advantages of the invention are the following:
(1) Any combination of letters, words or figures can be shown as being made of, and from, its elementary parts.
(2) Many combinations of letters, words or figures can be formed in a very short time.
(3) The viewer can be reassured of the elementary parts of any combination--quickly, repeatedly, clearly and without effort.
Some examples of educational devices in accordance with the invention are shown in the accompanying drawings, in which:
FIG. 1 is a top plan view of one form of device in its flat state;
FIG. 2 is an underneath plan view of the device shown in FIG. 1;
FIGS. 3-8 are further top plan views of the device, FIGS. 3-7 showing different flaps folded over;
FIGS. 9-10 are top plan views of two devices shown in FIGS. 1-8 in use together; and
FIGS. 11 and 12 are top plan views of two further forms of device.
The educational device shown in FIGS. 1-8 comprises a single planar sheet 10 of thick paper, cardboard, synthetic plastics or other material (which, in certain cases, can be transparent) divided into a number of squares or oblongs 12, 14, 16, 18, 20, 22, 24, 26 and 28. cuts 30, 32, 34 and 36 are formed along some of the dividing lines so that all the squares or oblongs except the centre one 20 form flaps which can be folded inwards or outwards about one or other of the dividing lines.
As will be seen from FIG. 1, the letters T, O and P have been printed on the front surface of each of the squares or oblongs 18, 20 and 22 respectively, while the front surfaces of the other squares or oblongs are blank. FIG. 2 shows, however, that the letters H,
