Revisitando o Liber Abaci: contribuições históricas e possibilidades didáticas para o ensino de matemática no 9. ano do Ensino Fundamental

Abstract

This study aims to investigate the didactic possibilities of the work Liber Abaci, by Leonardo of Pisa, known as Fibonacci, for the teaching of Mathematics in the 9th grade of Elementary School. The research is characterized as bibliographic and documentary, with a qualitative approach and a historical-pedagogical nature, based on studies about the History of Mathematics, didactic sequence, and the skills established by the Brazilian National Common Curricular Base (BNCC). Three problems from the work were selected: the Rabbit Problem, the Money Duplication Problem, and the Society Problem, relating them respectively to the concepts of functions, exponentiation, compound interest, and proportionality. As a result, a didactic sequence composed of five classes was developed, seeking to bring students closer to historical problems and promote the understanding of mathematical contents through contextualized situations. It is concluded that the use of Liber Abaci can contribute to making the teaching of Mathematics more meaningful, by presenting the discipline as a historical and human construction linked to the solution of real problems.
