This study attempts to demonstrate that a child with learning disability (LD) can successfully acquire the algorithms for addition and subtraction by means of progressing through a sequence of steps or learning stages which are represented here by the labels 'Real World, ' 'World of Models, ' 'World of Schemas, ' and 'World of Mathematics.' The sequence of the learning stages is the idea of teaching/learning adopted by many Japanese teachers for non-LD children. Specific features of LD are here identified and clarified through observation of the learning difficulties which are exposed within remedial teaching processes. The subject under study here was a fourth-grade pupil who was unable to perform adequately even elementary-level, first-grade calculations. The child's subtype of LD was classified as 'global'. The approach taken to remedial teaching was based on the Suido-Method. The results of this study indicate that a child that exhibits LD can nonetheless succeed in being able to manipulate mathematical ideas and to build the algorithms of addition and subtraction. Moreover, this particular child even managed to discover a new algorithm for subtraction. Five types of difficulties were observed which show potential for the diagnosis of LD : Persistence of Procedural Approach, Problems of Synthesizing, Problems of Attention, Low-Maturity of Meta-Cognition, and Slow Learning. Indications are strong that instruction and learning which incorporates meaningful approaches, such as in the Suido-Method, is more effective than so-called drill-and-practice learning such as is evident in the rote-learning method.
