As dificuldades dos alunos da EEM Virgílio Correia Lima em operações básicas com números naturais, inteiros e racionais

Abstract

During years of experience in the classroom we face several times with students who have great difficulty in learning mathematics, especially in key operations involving the sets of natural, integers and rational numbers. This paper presents a journey through numerical sets, showing its historical operations and construction, presenting concrete facts of the difficulties encountered by students in basic math operations and statistical data prove that the student enters high school in EEM Virgílio Correia Lima without the domain of fundamental operations. Finally we present arguments that show the main factors that allow our students entering the high school without mastering the fundamental operations, among which we highlight the fact that teachers responsible for mathematics literacy, teachers in early elementary school, are not mathematicians; mathematics teachers from 6th to 9th grade in elementary school does not have adequate training; and the discrepancy between curriculum and workload, because we have a curriculum in elementary school too extensive for a limited workload.
