Abstract Toy blocks and sets of toy blocks containing Braille characters for teaching young, sight-impaired children. A typical wooden block is cubical, comprising a pair of opposite, spaced apart display sides having recessed surfaces. One recessed surface contains a raised Braille character, and the opposite side displays the corresponding alphabetic or numerical character or characters. The recessed sides have borders comprising a bottom tactile-sensing portion that includes a plurality of raised nubs adapted to be touched for orienting the characters properly. Smaller Braille characters are preferably disposed beneath each alphabetic character.
