Abstract
An apparatus for teaching Braille letters, words and sentence structure is disclosed. The present invention provides the construction of a number of blocks, each containing the appropriate dot arrangement on its surface to represent a Braille character, sound, word, or number. The Braille blocks are similar in construction to a two by three matrix Lego.TM. brand building block. However, the two by three matrix of dots is altered such that the dots on a block are representative of a Braille character. The present invention also involves the structure of a rigid board upon which the Braille blocks may be affixed. This board allows for the creation of words and sentences upon its surface. The board also prevents the inadvertent jumbling of the blocks placed upon it such that a tutorial lesson is not interrupted by any disturbances. This feature is particularly important when one is teaching the young or the retarded to read Braille.
