Investigando problemas aritméticos, algébricos e geométricos com o Geogebra e o Gnu Octave

Abstract

In this work, we propose didactic activities for mathematics teachers in Basic Education to employ/adapt when addressing content such as divisibility, functions, matrices, areas, volumes, and conic sections in the classroom. In developing the didactic activities, we use problem-solving via digital technologies as a methodological resource, covering specific competencies and skills outlined in the National Common Curricular Base (BNCC) and the Curriculum Reference for High School in Paraná (RCEMP). We solve the problems structured in the didactic sequences with the help of GeoGebra and GNU Octave software, which are freely accessible remotely. These problems are extensions of propositions and stories in two of Malba Tahan’s works: “The Man Who Caunted” and “Amusing and Curious Mathematics”. We conclude that using digital technologies to solve arithmetic, algebraic, and geometric problems makes it possible to particularize/generalize results and interrelate content.
