The application is based on a didactic package created to develop language skills, communication and scientific school thinking. The learning approach of this game is anthropological and socio-constructionist and is based on ethnographic studies developed with schoolchildren from northern Chile to collect their representations about biodiversity and the environment. The treatment of reading texts and images constitutes a contextualized selection in the "nortina" culture, functional to learn the environment and meaningful for schoolchildren between 5 and 10 years old. With this didactic material it is intended that students recognize and value the characteristics of biodiversity as an approach to the assessment of their identity and the characteristics of the fauna of their environment. The Porta ABC allows to learn and reinforce the graphemes (letters) and the phonemes (sounds) of the letters of the Spanish alphabet of Chile, in order to advance simultaneously in the learning of instrumental, functional, scientific and digital literacy, and to value natural environment and the biodiversity of "La Portada" Natural Monument of Antofagasta.
