摘要：Duval’s Semiotic Representations Theory was the guiding theoretical reference to the present research, which mainly focused on identifying the possible mental representations elaborated by first grade students of Elementary School, by means of records obtained in activities mediated by digital games. The data collection methods, carried out as a research at the Pedagogy undergraduate level as a requirement for graduation were video recordings and written registers produced by students. The data analysis identified the formulation and manifestation of mathematical concepts representations. The data were analyzed according to the methodology proposed by Henry (2006), under Duval’s theory (2003), and the results indicated that the registers presented by students had a close relationship with the competencies developed during the game and the resolution of written activities at the same category. Therefore, this research provides the study of situations involving students who must interpret and convert different types of semiotic representations in order to understand the complex process of mathematical concepts by children.
