Abstract

The article is guided by the objective of discussing the resolutions of tasks in- volving 1st Grade Polynomial Function, carried out by two High School students from a state school in Minas Gerais. The theoretical framework refers to cognitive demands as the organizing axis of the Mathematics curriculum, as well as the reasoning mobilized by students. The analysis made it possible to identify that they present different reasoning when solving tasks that demand high cognition. The resolutions of one of them show the mobilization of reasoning with low cognition, which can be interpreted as a lack of unders- tanding of the task and concepts; the resolutions of another show the mobilization of more complex reasoning. Such results require teachers to have knowledge regarding the types of reasoning when reading, interpreting, evaluating and selecting tasks in curricular materials when creating learning situations with a view to enabling the formation of concepts and the mobilization of varied reasoning.
