Divisão de Números Decimais – Proposta de Uma Estratégia Metodológica para O Ensino na 5ª Classe

Abstract

The study of decimal numbers, according to the mathematics programs of the current system in our country is approached from the 3rd grade of Primary Education, with the operations of addition and subtraction; in 4th class, the multiplication of decimal numbers, in addition to addition and subtraction. However, only from the 5th grade is the division of decimal numbers. This paper presents a study, with a predominantly qualitative approach, of descriptive character. The current state of teaching of the decimal number division was analyzed, where with the application of different research instruments, among which we highlight the fact that in the observation and questionnaires, the results showed that there are many difficulties in the teaching process. Mathematics, concerning the teaching of the division of decimal numbers, thus conditioning the good learning by the students. To solve the identified problem, a methodological proposal was elaborated, for the division of decimal numbers in the 5th class, in the context of the theme “Numbers and Operations”. In the design of teaching strategies, an approach based on daily problem solving was used, where the student has the opportunity to learn mathematics, relating it to their daily lives. Finally, the methodological proposal was submitted to the experts to be validated.
