TEACHING PROBABILITY AND STATISTICS IN ELEMENTARY AND MIDDLE SCHOOL IN BRAZIL'S COMMON NATIONAL CURRICULUM BASE

In this article, the curricular guidelines of the National Common Curricular Base are studied and discussed regarding the thematic unit of Probability and Statistics, in the Elementary and Middle School in Brazil, considering the current guidelines for the teaching of this thematic. Adopting a qualitative approach and using content analysis, the study of curriculum guidelines begins by analysing the general aspects of the thematic unit and continues with the detailed analysis of the Probability and Statistics subunits, distinguishing in each of them two school levels: the initial years (from 1st to the 5th grade) and the final years (from the 6th to the 9th grade). In terms of results, with reference to the current guidelines for the teaching of Probability and Statistics, in Probability emphasizes the exploration of everyday situations and random experiments (simulated or real) and the omission of games of chance, while in Statistics it stands out investigative projects, construction, determination and interpretation of statistical tools and the use of digital technologies, namely electronic spreadsheets.
