The objects of teaching and learning are present in classrooms for many years. Teachers use them to make education more dynamic and sometimes fun. However, few researches are related to the material, in most cases they address only the textbook and not the objects made by the teacher. In this research, objects of teaching used in the classrooms of two schools of Rio de Janeiro are presented, one based on traditional pedagogy in teaching and other montessoriana. The differences between the materials are clear: the form of construction, raw materials, printing of texts, images, etc. These elements can make the material more visually rich and facilitate the seizure of the content. But the teachers know little about theories of Design and Visual Communication, to work these elements effectively. The objective of this dissertation was, understanding the means and modes of production of teaching materials made and used by teachers. What they think, how they made the objects, which raw materials are used, how is the choice of images and typography to be in material, were some of the questions that guided the search. As results, the importance of design work in schools, the need for a designer working with teachers in developing these materials were evident and some suggestions for teachers at the time of preparation of the material were presented.
