This document shows the use of the calculator to assist in solving different divisions of students in fourth grade of elementary school, through the interaction in its components (divisor, dividend, quotient and remainder). Worksheets were used with a constructivist approach, which provided the student self-assessment tests. The teacher's role was helpful when deemed necessary, in order to develop in students' self-directed learning in an environment of problem-solving and teamwork. This study used a divide-by-sides method, which was effective to understand the conventional algorithm of the division and move from the division of one number in the divisor to the double-digit divisor, without losing the sense that it involves. In the testing study, various methodological tools were used. (Contains 6 figures.) [The author in this study was supported by IPN (Institute Polytechnic National).]
