Álgebra escolar: problemas de estrutura algébrica no 7°ano do Ensino fundamental

Abstract

Mathematical problems help students understand the meaning of mathematical knowledge, as well as the development of reasoning ability. This paper aims to show that the application of a didactic sequence composed by mathematical games workshops can contribute to the 7th grade elementary school students to develop problem solving skills of algebraic structure. Starting from the birth of algebra and school algebra, going through the usefulness of the problem solving equations, collecting results in 8th grade classes of public schools in the 7th grade. It is in the 7th grade of elementary school that the student has his first contact with the study of algebraic structure problems. Then, the didactic sequence composed of game workshops was applied, collecting data before and after its realization. The acquired results were analyzed and the work investigated if these results were favorable. The acquired results were analyzed and the work investigated if these results were favorable. If the results were not favorable, one of the schools investigated was chosen to apply the didactic sequence of intervention, aiming to obtain more significant results. For this work, we consider as significant results those that are superior to the results collected before the application of the workshops. Finally, the paper seeks a reflection on the acquired results and also seeks to propose suggestions for future work.
