Usando puzzles, origami e tecnologias digitais no estudo de frações, números irracionais e áreas na educação básica

Abstract

This work presents dynamic activities involving the puzzles Tangram, Stomachion by Archimedes, Disorientation, and Trinity Quartet. These four puzzles are explored to make the study of fractions, irrational numbers, and the calculation of the area of plane figures more engaging and playful in Elementary Education. The activities have been organized into a digital book, the educational resource developed in this project, using the GeoGebra platform. Additionally, we propose constructing the puzzles through origami, the ancient Japanese art of paper folding, without cuts or the use of glue. We conclude that solving geometric problems through puzzles, origami, and digital technologies aligns with the specific skills and competencies outlined in the National Common Curricular Base (BNCC). This strategy makes mathematics teaching more attractive and meaningful, without compromising theoretical rigor and mathematical precision.
