Making constructions with paper is called “origami” and is considered an art. The objective for many fans of origami is to design new figures never constructed before. From the point of view of mathematics education, origami is an interesting didactic activity. In this article, the authors propose to help High School students understand new mathematic concepts, and to revise concepts already known, through the origami activity of building a cube. There are many didactic materials for working on Geometry. Here the authors propose the use of one which it is certainly not new–paper. They focus on the use of paper for the teaching and learning of geometry as it is a manipulative material and, it helps to involve students in mathematical activity and to promote making sense of, and giving meaning to, mathematical concepts. In previous work the authors have focused on the teaching and learning of plane geometry concepts such as parallelism, perpendicularity, polygons, angles, etc. through the use of paper. This time they decided to address the teaching of three-dimensional geometry that will also inevitably tackle some concepts in plane geometry. In this context, fractions and the measurement of surfaces and lengths are also involved.
