Abstract
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.
The many procedural misconceptions in the material of addition and subtraction operations are the main triggers for the low mathematics learning outcomes of children at the elementary school level. To bridge abstract material with the thinking characteristics of low-grade students, this classroom action research (PTK)...
Many junior high school students experience difficulties in understanding abstract geometric concepts, limiting the development of their geometrical thinking. This quasi-experimental study employed a non-equivalent control group design involving 150 seventh-grade students. The experimental group received GeoGebra Augme...

Learning activities that mainly rely on lectures and textbooks tend to limit students' active participation, causing them to memorize concepts without fully understanding their meaning. This issue is particularly evident among children aged 6–7 years, who are still in the concrete operational stage of cognitive develop...

Most students struggle to grasp abstract mathematical concepts such as measurement, area, and volume when instruction relies only on textbooks and static diagrams. This study investigates how augmented reality (AR)-based instruction can enhance mathematics achievement by providing interactive and experiential learning....

Fourth-grade students at SD Negeri 1 Pejambon showed low mathematical problem-solving skills in learning plane geometry. This condition was associated with the limited use of teaching aids, insufficient opportunities for students to construct plane shapes independently, and a lack of concrete problem-solving activities...
