Base Nacional Comum Curricular: indicativos para o letramento matemático no eixo temático números no 1º ciclo do Ensino Fundamental

Abstract

The teaching of mathematics at many moments can be seen as a complex and difficult process, however some teaching perspectives can corroborate to the rupture of these paradigms. In this work we defend the perspective of Mathematical Literacy as a triggering means to facilitate the process of schooling and formation for citizenship. We had as theoretical contribution: Fonseca (2004); Soares (2003); D'Ambrósio (1993); Silva et al (2016); Freire (1999); Danyluk (1994); Galvão & Nacarato (2013) and among others. In this study we analyzed the indicatives that the National Curricular Common Base (BNCC), a document that seeks to standardize Brazilian education, guaranteeing learning rights at the national level, points to Mathematical Letting in the thematic axis numbers for the 1st cycle of Elementary Education, specifically knowledge objects and skills for the first three years of elementary school. Categories of expressions were constructed to analyze these indicatives: Daily life; Significant Problems and Interest; Strategy and Personal Registry; Resolve and Elaborate Problems and No expression was used. In the 21 objects of knowledge proposed for the 1st cycle, no explicit mention is made of mathematical literacy; sixteen of the 21 skills are indicative for the same. In all the skills of the first year an expression that refers to Mathematical Literacy was identified. In the second year, four expressions were counted and in two skills no expression was found and in the third year only four of the seven skills addressed one of the pre-defined expressions, and three did not make references. The expression that appeared the most is "strategy and personal registration" and the one that appears least is "everyday". From this we propose sequences of activities, based on the perspective of Mathematical Letting, starting from three perspectives of Mathematics teaching: game use, ethnomathematics and children's literature, which in our view could contribute to the teaching and learning process in this axis thematic We used as a type of research, the documentary, to guide us while data collection and data analysis was used the content analysis perspective.
