Desafios na aprendizagem das quatro operações utilizando os números decimais nos anos finais do ensino fundamental - um estudo em uma escola municipal de Teresina- Piauí

Abstract

This work aims to identify and analyze the difficulties in learning the four operations using the decimal system in the final years of elementary school at a Municipal School in Teresina, Piauí. The research sought to assess the students' knowledge level and the main difficulties in the operations of addition, subtraction, multiplication, and division with decimal numbers, as well as the problem-solving that involved these numbers. Specific objectives were established, including identifying the students' difficulties and analyzing the factors that hinder the understanding and application of these concepts. The adopted methodology was a field research, using a questionnaire on decimal numbers applied to 6th-grade students of Elementary School. The results obtained reflect the difficulties in learning decimal numbers already highlighted by some authors, such as Nicolau (2014) and Moreira (2020). The research aims to contribute to the understanding of difficulties in mathematical learning involving the decimal system and provide subsidies for the development of pedagogical strategies that promote more effective and inclusive mathematical education.
