The study aimed to identify the sources of mathematics learning Disabilities for middle school classes from the point of view of supervisors and teachers and their suggestions to address them. The study sample consisted of 38 male and female supervisors and 151 teachers for the mathematics course who were chosen by the available random method during the first semester of the academic year 2021 / 2022. To achieve the objectives of the study, a tool was prepared that consisted of four subscales (36 items), namely the student, the teacher, the textbook, and the classroom environment. The results showed that the textbook ranked first, followed by the student, and then the teacher. The average responses of the study participants on the survey subscales were moderate, and there were no statistically significant differences attributed to the job title and gender variables and there were statistically significant differences attributed to the educational qualification variable and in favor of the bachelor's holders. There were statistically significant differences due to the number of years of experience in favor of the participants who have less than 5 years of experience. The study recommended holding training courses for mathematics teachers to find out a specific mechanism in dealing with people with learning difficulties.
