This article aims to describe and analyze the possible didactic sequences practiced by Mathematics and Natural Sciences teachers at Elementary, Middle and High Schools of Presidente Prudente (SP), in order to identify implicit patterns in these sequences which may reveal the teaching conceptions of these teachers. When 76 Mathematics teachers and 61 Natural Sciences teachers were analyzed, we verified that the predominant action of the teacher is in three parts of the class (beginning, development and assessment). The teacher initiates the content, establishes a sequence, exposes and determines procedures, concludes and assesses it, and the students are supposed to execute the activities. There is a difference between the sequences described in both areas and some peripheral efforts trying to overcome the traditional model of teaching. This issue is discussed taking into consideration the teachers' knowledge about teaching and their pedagogical formation.
