To answer this, the general objective is to analyze the effects of a didactic sequence in teaching Measures of Central Tendency and its implications for the learning process of 9th grade students of Elementary School. The specific objectives were established: to conduct a study of official documents on the teaching and learning of measures of central tendency, to analyze the results obtained by the didactic sequence and to construct a didactic sequence from the perspective of the Theory of Semiotic Representation Records. The research was based on Duval's Theory of Semiotic Representation Records (2012) and the Didactic Engineering of Artigue (1996) is being adopted as the methodological framework, based on its four phases. In the preliminary analyses, the study of official documents, the literature review, the mathematical object and the records of semiotic representation and the knowledge of the students are being worked on. In the a priori analysis of the activities, we produced a Didactic Sequence related to the content of Measures of Central Tendency (Mode, Arithmetic Mean and Median), based on the assumptions of the Theory of Records of Semiotic Representation, in which the concepts to be worked on through their representations in natural, tabular and graphic language. During the application of the teaching sequence, it was possible to identify advances in student autonomy, logical reasoning and cooperation in group activities. Thus, it is considered that the teaching material used has relevant potential to explore measures of central tendency in the classroom. It is expected that the Educational Product developed from this research will contribute significantly to the initial and continuing education of Basic Education teachers.PPGEM - Metodologia para ensino de matemática no nível fundamental
