Olimpíada brasileira de matemática das escolas públicas: uma análise de problemas sobre progressões

Abstract

The educational issue in Brazil is, in part, related to the low understanding of mathematical content and, consequently, the insufficient performance of students generates concern among educators in the area who daily seek strategies to minimize this situation. Seeking to establish alternatives that arouse student interest in the subject, a bibliographical study was envisioned on the possibilities of using questions from the Brazilian Public Schools Mathematics Olympiad - OBMEP, in the classroom context in order to stimulate greater student interest by the area, bringing healthy competitiveness to daily school life and not only for the application of the event's tests, given that the knowledge and skills required by the OBMEP are of paramount importance to scientific encouragement and deepening, as they are addressed in order to stimulate the exploration of research and consequently the development of greater affinity with mathematics. Therefore, aiming to identify, based on the National Curriculum Parameters - PCNs, the skills needed to solve the problems proposed by the OBMEP on the topic of progressions, were six questions were selected with the respective resolutions proposed by the test preparation team and in some cases alternative solutions were proposed. At the end of the research, it is possible to identify that the issues proposed by the Olympics can indeed contribute to improving understanding and, consequently, learning about the topics covered.
