Cálculo mental no ensino fundamental: uma análise de atividades em cadernos e livros escolares de alunos do fundamental menor

Abstract

Considering that it is essential to develop reasoning to find quick and efficient solutions to mathematical challenges, mental calculation is a valuable strategy for this, as it stimulates the mind to deal with situations that require greater concentration and intellectual preparation. In this way, the research is introduced into the field of History of Mathematics Education and aims to investigate to understand study techniques/methods to stimulate mental calculation, verify methods that facilitate the teaching and learning of mathematics from mental calculation in life of elementary school students. The work development methodology was investigative through exploratory and qualitative research, that is, studies, analysis and synthesis of information. The research results indicate that mental calculation in mathematics teaching-learning is inserted as a pedagogical tool in problem solving, teaching that should seek to develop in children the skills of speed, safety, precision, ability to estimate, exercising memory and strengthening reasoning, deepening intelligence, thus making a considerable and important difference in teaching, as a process of teaching practice and student learning content.
