MATHEMATICAL LITERACY AND LEARNING RECOVERY: A PRACTICAL EXPERIENCE WITH POLYHEDRONS AND ROUND BODIES IN THE 6TH GRADE OF ELEMENTARY SCHOOL
This article reports the experience of implementing a didactic sequence on the study of 3D geometric shapes (polyhedrons and round bodies), grounded in the principles of Ethnomathematics and Critical Mathematics Education. The main objective was to promote the recognition of geometric properties in everyday life and the development of spatial perception, enabling students to distinguish solids and their nets. The adopted methodology was characterized as a literature review, based on the National Common Curricular Base (BNCC) and the Learning Recovery Matrix of SEDUC-TO, combined with participant research, in which the teacher mediated the transition from abstract to concrete thinking. Manipulative materials and the educational support of the Projeto Aprova Brasil were used to study three-dimensional models. The results achieved demonstrate that the tactile and visual approach reduced resistance to mathematical content, allowing students to clearly identify elements such as vertices, faces, and edges, in addition to consolidating their understanding of Euler's Formula in an intuitive and collaborative manner.
