This experience was carried out during two 50-minute classes in a 9th gradeclass of a public school in the city of Feira de Santana/BA. All enrolled teachers participated who, in pairs, worked with students organized in groups using kaleidoscopes with 2 and 3 mirrors. Reports from future teachers highlighted that they were delighted with all the students' participation in the activity; considered it a very interesting activity, which captivated both future teachers and students, and that in the teaching experience, mismatches were perceived and reported, but that these generated reflections on the tasks and some difficulties manifested by the students. Considering these reports and understanding the teacher as a professional whose task is to teach, and training as a form/action, it can be concluded that the teaching experience waspleasurable for students and teachers, showing that kaleidoscopes are promising resources in teaching the concepts of geometry, with easy adherence and implementation in future classes. Thus, the teaching of teacher trainers will contribute to the form/action of future teachers with a humanistic view of mathematics present in the various spheres of society and in problem solving.
