It seeks to answer the following question: What contributions does a didactic sequence, structured on the Theory of Semiotic Representation Registers, offer to the teaching of probability in the 2nd year of High School? The main objective was to examine the contributions of a didactic sequence aimed at teaching Probability. The study was supported by Duval’s Theory of Semiotic Representation Registers and methodologically grounded in Michèle Artigue’s Didactical Engineering. The investigation involved the analysis of official documents, a review of specialized literature, the application of a diagnostic activity, the design of a didactic sequence composed of six blocks of activities, and, subsequently, its implementation followed by an a posteriori analysis. The findings revealed that the adopted approach significantly contributed to overcoming initial difficulties, encouraged the conversion between representation registers, promoted greater articulation among concepts, and fostered logical and argumentative reasoning.PPGEM - Metodologia para ensino de matemática no nível médio
