    • A symbolic language teaching and communication system is disclosed which includes at least one block (10) having a pattern of raised protrusions (16) with rounded top surfaces for tactile discrimination. Each pattern represents an alphanumeric character for recognition by a visually impaired individual. The block has indicia (18) on one of the sides (15) corresponding to the alphanumeric character for recognition by a nonvisually impaired individual. Each block also has a curved region (17) to provide for the proper orientation of the block on a block retaining slate when forming words or sentences. The block retaining slate (40) also has a rounded corner (52) to provide for the proper orientation of the block retaining slate when forming or reading words or sentences. The block retaining slate has a triangular portion (62) between the engaging members to provide for proper alignment and spacing of the blocks on the retaining slate.
