This article presents the results of a research, based on a didactic experiment, which had as subjects a group of students from the ninth grade of elementary school. The study had as its theme the generalization of standards and foresaw the realization of sessions to solve problems that had as part of the strategy the use of technologies, including digital ones, with an emphasis on the GeoGebra software. Thus, the investigation assumed a qualitative character, with an outline supported by the concepts of didactic engineering. In theoretical terms, the investigation found support in the theory of didactic situations and in authors related to the central theme, such as Dreyfus, Zazkis and Mason. The interactions between the pairs formed to solve the problems showed that the planned didactic strategy allowed the subjects to reflect on the proposals addressed, providing mathematically valid solutions for the activities, using a set of available technologies, digital and non-digital, in convergence.
