Objective. The purpose of this research was to describe the change in performance (achievement and types of representation employed) of students attending a school for deaf people in the city of Cali, after receiving instructions in the use of the assignment algorithm proposed by Nunes and Moreno (1998b). Method. For this purpose, a descriptive study was carried out, in which a pre-test and post-test formula were used, as well as a descriptive comparison with control group. Eight students took part, to form two groups of four members each. As an instrument of evaluation, a battery of arithmetical problems was applied in arabic format, and in Colombian sign language (CSL), in the pre as well as the post test. The intervention consisted of five sessions in which an explanation was given to students on the use of the algorithm for solving problems of addition. Results. A descriptive statistical analysis was carried out for categorized variables, which showed differences in percentages of achievement, ways of problem representation and the use of strategies in the post test group. Conclusion. The conclusion drawn from the results was that an educational strategy designed for deaf people could help to improve learning of basic mathematical concepts.
