A matemática nos anos iniciais: uma análise de atividades de probabilidade e estatística

Abstract

The objective of this research is to identify the mathematical knowledge explored in activities proposed in Elementary School classes. The mathematical activities were collected in a school in the western region of the state of Santa Catarina, from March to September 2019, separated and analyzed according to the objects of knowledge common national curriculum base (Base Nacional Comum Curricular - BNCC). The research was theoretically based on Curi (2006), Nacarato (2010) and Marim (2011) who point to the training of teachers who teach mathematics and some ways to minimize gaps. For the analysis of Probability and Statistics activities was based on Lima (2005), Curcio (1989), Sztajn (2002) and Selva (2003) who point out the types of knowledge, levels of understanding of graphics and their main difficulties in graphic construction and representation. In addiction, the guiding documents were presented in order to relate the activities with what they point out. The results indicate that mathematical concepts and interdisciplinarity issues were highlighted in the activities. And, the levels of understanding of the graphical representation were identified and seen, showing the importance of the teacher having mastery over the types of knowledge.
