The study aimed to investigate the effectiveness of some constructivist learning strategies to develop the mental arithmetic of students with learning disabilities mathematics in the third grade of primary, the two researchers adopted the semi-experimental approach using the one group method. The study sample consisted of (6) students. To answer the study questions, that by preparation a training program consisting of sessions containing practical application of constructional learning strategies for the development of the mental arithmetic and verify this by mental arithmetic skills test. The results showed that there were statistically significant differences at the level (α≤0.05) between the mean scores of the research sample in the measurement (pre-post) to test the skills of the mental arithmetic which is attributed to the use of some constructivist learning strategies. This confirms the effectiveness of the program in the development of mental arithmetic. (Published Abstract)
