Modelo de barras na resolução de problemas ao longo do ensino fundamental

Abstract

This dissertation aims to present the Bars Model as a proposal for teaching Mathematics through problem solving. This methodology has achieved success in the transition from arithmetic to algebraic thinking. The work presents the theories that underlie and guide the work of teachers from mathematical literacy to the end of Elementary School. Exercises of increasing difficulty are exposed so that those involved in the preparation of classroom activities become familiar with the pictorial approach to solving word problems. The construction of the Bars Model is exposed with its theoretical aspects of the Singapore curriculum. This country introduced and consolidated word problem solving through the Bars Model. Finished the work with a collection of exercises extracted and adapted from books from Singapore and other countries to exemplify the range of problems of the different subjects that can be explored with the Bars Model. (BNCC) that the teacher will develop in their classroom activities.
