• Abstract:

  This study aims to analyze how semiotic representations can efficiently contribute to the learning of rational numbers in a clear and accessible way, enabling a gain in the cognitive functioning of students in accessing rational numbers, in terms of coordination and production in interpretation of the quality of knowledge, applying algebraic and geometric problem solving mechanisms, improving understanding. As a methodological procedure, a field research was adopted, where 32 students from two classes of Elementary School, of both sexes, belonging to two State Schools in the State of Pernambuco were interviewed. It was evident in this study that the elements introduced to reduce the difficulties in relation to the rational ones were of great significance in teaching and learning, especially from the point of view of the evolution between the first and second tests proposed to the students. It was possible to evaluate the practice in the comparison of results in relation to the difficulties that we seek to minimize.
