A álgebra no ensino fundamental como ferramenta de generalização

Abstract

This paper aims to describe the application of a didactic sequence for an approach to algebra in elementary school, and the generalization as a teaching resource. This teaching sequence was built according to the recommendations of the National Curriculum Parameters (PCN). Also featured are reports of some civilizations and methodologies applied to solving algebraic character problems. There is talk also about some mathematicians who contributed in the development of algebraic symbolism. Soon after, presents an account of how algebra was introduced in Brazil and how it is being charged in tests that serve as parameter for analysis of the Basic Education Development Index (IDEB), as Exhibit Brazil and International Program student assessment (PISA), then passed to the report presented to the students, through slides and videos on existing patterns in nature. Finally, the manner in which students developed reasoning perception patterns of numerical sequences and figures are presented, culminating in the construction of figures sequences with the use of concrete materials, activity performed in groups, which provided a link between theory and practice.
