The purpose of this study is to determine the effect of a specialized teaching device on the arithmetic achievement of mentally retarded children. Mentally handicapped children need concrete learning experiences. Audio-visual materials not only aid learning but they also extend and enrich the child's education. The Math Builder was used to reinforce student skills after the basic concepts had been introduced. The principal objectives considered in the development of this study were: 1. To provide training in developing accurate responses to the basic number facts. 2. To afford practice with the basic number facts as met by the child in everyday experiences of his life. 3. To ascertain the effect of this training and practice with the Math Builder on the arithmetic achievement of mentally retarded children. Arithmetic is like a jigsaw puzzle. When all of the pieces or steps are in proper places the picture can be seen, but if two or three pieces or steps are missing, there is no logical relationship. It is the purpose of the present research to help the retarded child find the missing pieces, and thus be able to achieve in arithmetic.
