Abstract
Abstract Educational sign language blocks are set forth as an educational tool to enable individuals to enhance an understanding of sign language, as typically utilized by hearing impaired individuals. The individual sign language blocks each include a designated letter of the alphabet and an associated symbol corresponding to that letter to reinforce the noted alphabet letter and further including a removable side face including the appropriate sign language designation for the aforenoted letter. The removal faces are each provided with three projections to correspond to three recesses within an associated face of the block. The pattern of recesses and projections are varied for each of the individual blocks whereupon an individual attempting to associate the appropriate sign language symbol with the designation or letter on the block must choose correctly or else the removable face will not mate due to misalignment of the projections and recesses.
