O ensino dos números racionais nos anos finais do Ensino Fundamental: uma análise de produções brasileiras nos últimos dez anos

Abstract

This paper presents a mapping of Brazilian research published in journals of mathematics education, dealing with rational numbers. To this end, it seeks to theoretical foundation in ideas Onuchic and Allevato, Lamon and Romanatto and the proposed curriculum National Curriculum Standards. The methodological choice is a qualitative study of document analysis type, and the data analyzed by the steps of content analysis. Thus, it can be seen that little research has been developed with students of basic education and that among the research identified the most discussed meaning is part-whole. Moreover, few productions have suggestions for activities involving rational numbers. Thus, we see the need for more research involving the relationship between the different meanings of rational numbers and students of basic education.
