The study is to find out effects of teaching and learning through play-based activities in order to improve arithmetic capacity of production of children with mathematic learning disability. The subjects of this study selected two children with mathematic learning disability attending J elementary school, in Pusan city. Their intelligence quotient appeared 85-95 by KEDI-WISC, showed two year delay at capacity of addition, subtraction. The duration of intervention was 10 weeks, twice a week, after activities, formation appraise was practiced once a week to investigate capacity of addition and subtraction and in post-test step, once a week, during five weeks. The findings showed that during intervention steps than pre-steps, capacity of addition and subtraction of children with mathematic learning disability improved, in post-steps than pre-steps, capacity of addition and subtraction improved. The conclusions of this study are as follows; learning through play-based activities have an positive effects on capacity of addition and subtraction of children with mathematic learning disability. The suggestions based conclusions of the study are as follows; There are many limitation in generalization to all children with mathematic learning disability because of the subjects of the study two children mathematic learning disability. So future study should be implemented to verify the effects of application to many children with mathematic learning disability.
