Um estudo de questões da OPEMAT sobre análise combinatória

Abstract

We can find applications of mathematics in many everyday situations, however, when we enter the classroom environment, we see students who are still uninterested in this subject, which is so important for solving different everyday situations. Thinking about making mathematics more attractive to students and motivating them with regard to applicable knowledge in this area, there is OPEMAT (Olimpíada Pernambucana de Matemática) in the state of Pernambuco, which promotes training for teachers, thus encouraging the stimulation of teachers and students to constantly apply mathematical concepts. Therefore, this work aims to analyze combinatorial analysis issues of the OPEMAT tests, comparing the test answer sheet with the resolution using an alternative method, which may be easier for the student. In this work we address different ways of solving 4 questions that correspond to the second level of the OPEMAT test. After the resolutions, it was possible to observe that there are possibilities of reaching the same official template using other mechanisms. With this, it was possible to conclude that the student, using different techniques, can more easily solve combinatorial analysis questions, also showing that it is important to practice solving questions, so that the student acquires more familiarity with problem solving and can have different means and experiences to solve math questions more easily
