Trabalhando a multiplicação com o uso das Barras de Napier

Abstract

This work had as general objective to develop a proposal of activities involving the use of the Bar of Napier in the facilitation of the teaching learning of the student in the operation of multiplication. To do this, we outline specific objectives: Diagnose the main difficulties of students in the multiplication operation; To elaborate a proposal of activities involving the use of the Napier Bars and the multiplication operation; To apply the proposal of activities in a classroom of the 6th year of elementary school; And Evaluate the potentials and limitations of the Napier Bars in the process of teaching learning the multiplication operation. In order to base this work, we are based on the National Curricular Parameters (BRASIL, 1998) and authors such as Boyer (1974), Eves (2011), Lorenzato (2006), Rêgo e Rêgo (2006), Passos (2006), Godoy Gil (2010), Pereira and Martins (2017) among others. It was an exploratory research with a qualitative approach. We found that the Napier Bar is a facilitating resource as it provides the student with individual manipulation as well as being motivating allowing students to use this material not only to calculate operations involving multiplication but also involving division and root-square extraction. We recommend that this research provoke future research that aims to work with our proposal of activity in the training of teachers and next to the students of High School.
