Assembly of equipment pedagogic comprising a novel presentation of the letters in their three major forms of graphics by the use of a half - cubes

摘要

The teaching material consists of half cubes for the simultaneous presentation of different types of writing letters. These are printed or engraved on three rectangular faces, using two colours to differentiate between consonants and vowels. This also permits the playing of a simple jigsaw game using the square faces. The half cubes can also have numbers on one rectangular face, the others being used to give an image of the number and a different element for the jigsaw game. For the jigsaw game different shapes can be used.
