Os usos matemáticos por crianças de uma turma de pré-escola de Campo Novo/RS

Abstract

This Critical-Reflective Report is the result of an applied research that approaches the mathematical uses in a Preschool Class. The investigative questions were: What are the mathematical uses of a Pre-Kindergarten Class of 4-year-old children? How do school mathematical uses approximate other non-school experiences? The research was done in a Pre-Kindergarten Class, of a public school in Campo Novo / RS, with 20 children of 4 years old. The procedures were the observation, the planning and the experience of an Intervention Project. The theoretical references were based on Lorenzato (2006), D'Ambrosio (2011), Wittgenstein (1979), DCNEI (2009), BNCC (2017) and others. The analyzed materials considered the different mathematical uses, grouping the speeches and the photos that came closest, separating into three groups: "Mathematical uses in the classroom: the Market", "Mathematical uses outside the classroom: the walks" and "Mathematical uses with the Family". The analysis showed that the children interacted, playing with their classmates, using their previous knowledge, the non-school knowledge, which involved mathematical language, such as the idea of classification, comparison of products, the understanding of number (numeral and quantity), value and operations. This knowledge was used in the classroom, expanding theirs uses, in the bar code talk, packaging exploration, market shopping, calculator and cash machine operation. The results show that mathematical uses in various contexts, in the classroom, in the market and in the family are inserted without different language games, but that the rules are known and respected by the players.
