This article presents research developed with mathematics teachers in initial and continuing education when working with origami and video production. The participants developed activities related to Origami Geometry, involving Basics Origami Operations (BOOs), Haga’s Theorem, and aspects of video production. Through experimentation with folds in paper and the production of videos about origami, the participants produced mathematical knowledge, since it was observed that during interactions in the course, they argued using folds in paper to defend a mathematical idea and represented creases and their mathematical meanings in different ways, such as verbally, through diagrams, algebraic expressions, among others.
