Chemistry teaching learning is considered as difficult and boring. The definition of play, based on authors such as Freud, Piaget and Vigotsky, is presented as a stimulating, pleasant and voluntary activity that in the student facilitates his learning and encompasses the different facets of his physical, psychic, social and emotional development. The recreational aspect is to attract attention, impress sometimes, and create the opportunity to make scientifically reflect. This type of teaching materials is especially effective in showing us properties or characteristics of matter that are difficult to visualize due to their nanoscopic nature and that their understanding requires the development of abstract thinking. The playful didactic materials are cheap, and their use is feasible within the teaching classroom.
