Instructions for using and constructing approximately 58 instructional materials to aid young visually handicapped children in developing basic sensory concepts are presented. The materials are said to foster important ideas in variously aged children who have difficulty using their hands or understanding numerical concepts. Use of the materials is advised after students are exposed to different media indicating what hands can do and when students are prepared for readiness work. The materials are said to develop the following hand skills: handling, placing, putting together, arranging, fitting, pushing, pulling, assembling, and maneuvering. Directions are given for using the teaching aids, teaching according to main concept in sequence, obtaining commercial materials, and constructing the materials. Each material is presented in terms of description, purpose, behavioral objective, procedures, use, other materials needed, and directions for construction. Presentation is sequential, in order of large and simple to small and complex for attainment of the following concepts (number of materials for each concept is in parenthesis): form (11), position (nine), size comparisons (11), texture (five), similar and different shapes (nine), number (four), and enrichment of basic concepts (nine). Usually provided is a diagram and a photograph to illustrate materials such as the frame-a-circle, position peg board, big and little triangles board, texture matching blocks, sound matching board, and object concept plaques.
