Desenvolvimento do pensamento numérico através de uma seqüência didática na segunda série novo modelo educacional escolar para a segunda série

Abstract

Introduction: The article aims to demonstrate the use of a didactic sequence in the Escuela Nueva model, which due to its integrating characteristics must be present at various times in the process of developing numerical thinking. Objective: To analyze the effects evidenced by the implementation of the didactic sequence in the Escuela Nueva model, in the development of numerical thinking in second grade students. Methodology: Mixed research, in the line of research: development of mathematical thinking. It was carried out with students from the second grade of primary school, between 7 and 9 years old, from the Guavio de Fusagasugá Municipal Educational Institution. Results: To achieve this goal, a pedagogical proposal was designed and applied, which consisted of a didactic sequence that contains three sessions, where cooperative work is used, the game as a motivating agent, the use of didactic material that in turn is conducive to the students activities such as counting, numbering, relating, comparing, performing mental calculations as well as the use of addition and subtraction operations, which offered opportunities to enhance students' numerical thinking. Conclusions: Continuous and effective commitment was demonstrated, which allows to initiate a process of methodological and didactic change in the teaching and learning process in the area of mathematics, taking advantage of and adapting all the resources of the institution and the community, such as: physical spaces, didactic material and development of a playful pedagogy that allowed the interaction of students and teachers for the development of numerical thinking, demonstrating that through a didactic sequence, students build knowledge, make numerical relationships and learn significantly.
