چکیده:
Objectives: Dyscalculia is specific learning disabilities affecting the acquisition of mathematic skills in an otherwise normal child. The aim of this study was investigation of occupational therapy interventions effect on mathematical problems in students with special learning disorders.
Methods: 40 students with dyscalculia (2-5 grades) were selected and divided through randomized permuted blocks method into two groups 20 persons as intervention group and the others as the control group. Initially both of groups were administered by the "Iran Key math Test". Then intervention group received occupational therapy interventions for 20 sessions individually and two groups were administered by the Test again. Data was analyzed by using Paired and Independent t-tests.
Results: By the paired sample t-test the mean of total marks of Iran Key math Test demonstrated statistically significant difference in both of groups (P<0.05), but the measure of difference in intervention group was more than control group. The mean of marks of Basic Concepts, Operations and Applications demonstrated statistically significant difference at intervention group.
Conclusion: Occupational therapy interventions had clinical effect on mathematical problems in students with special learning disorders.

com Iranian Rehabilitation Journal ٢۵25 (1993), preparing math specifying test and comparing the performance of normal students to the students with math learning disorder, showed that there is a significant difference between the performance of two groups in total score, recognizing geometric shapes, size, one by one congruence concept, counting, recognizing sets and figures, visual- auditory constancy, locus value, four basic operations and problem solving(2).
In secondary math learning disability, the basic problem is language fundamental structures weakness, visual and auditory perception skills, motion, memory and attention, It prevents the students to do mathematical operations (3,4).
In previous studies, the effect of occupational therapy intervention in mathematical disorder has not been considered so much so, the goal of this study is effect of OT interventions in mathematical problems improvement such as math basic concepts, operations and application on affected primary school students with dyscalculia.
With due attention to the results of the present study it looks that this relationship has existed among students with learning disorders, and perceptual- motor abilities reinforcement have been effective in educational achievement specially in math.
Conclusion: Occupational therapy interventions have clinically effect on math problems improvement such as basic concepts, operations and mathematical application of students with dyscalculia.
