A Slow learner whose in IQ between 71 and 89 will have difficulties in solving mathematics problems that often lead to errors. The errors could be analyzed to determine the location and its type. This research is of qualitative descriptive, which aims to describe the locations, types, and causes of slow learner error in the inclusive junior high school class in solving the fraction problem. The subject of this research is one slow learner student of year 7 which was selected from on direct observation by the researcher and in consultation with math teacher and special tutor teacher which handles the slow learner students. Data collection methods used in this study are written tasks and interviews. The collected data was analyzed by Newman’s Error Analysis (NEA). The results show that, there are four locations of errors, namely comprehension error, transformation error, process skill error, and encoding error. There are four types of errors, such as concept error, principle error, algorithm error, and counting error. The results of this error analysis will help teachers to identify the causes of the errors made by the slow learner.
