Modelagem matemática e sequência didática: uma proposta de atividade

Abstract

In this study, we aim to present a design proposal for a mathematical modeling activity, following the assumptions of a didactic sequence. In this sense, the research adopts a qualitative approach, of a descriptive nature, based on the presentation and discussion of a mathematical modeling activity, from the steps of a didactic sequence in the understanding of the Fedathi Sequence. The Modeling activity brought for analysis had as its theme “Cristo Rei Parish Church”, with an approach indicated for students in the 8th and 9th grades of Elementary School. The activity presented has the potential to trigger a connection with history and cultural heritage, given the chosen theme, while mobilizing, requiring and building diverse mathematical knowledge such as: ratio, proportion, rule of three, calculation of areas, scale, units of measurement, similarity of triangles. The design presented allows us to consider that the development of a mathematical modeling activity, guided by a didactic sequence, highlights specific objectives inherent to the activity and that unfold in actions specific to the teacher and the student to achieve them. This work was prepared in the format of a scientific article, as part of the Final Course Work.
