This is an investigation about basic education system and, as its focus is to allow reflections about the mediating action of the teacher in investigative classes developed in scenarios for investigation, it has a line of research linked to school practices. To conduct the investigation, I chose students from three 7th grade classes of an elementary private school, in Goiânia-GO, in which I was the Mathematics teacher. As the essential part of the research problem is placed on the action of the teacher, I ended up developing a research on the practice itself, of a qualitative nature in a natural environment which is the school. To compose the field material, the classes were audio-recorded and photographed, the transcribed dialogues and students' classes records were collected and used to compose narratives about mathematics classes. The narrated plot that constitutes, at the same time, methodology and object of research, presents as categories of analysis the mediation performed by the teacher and the students' algebraic interpretation and understanding. The analyzes of the narratives propose the pedagogical approach and the dialogue as essential elements for the mediating action. As it is a Professional Master's Program, two e-books are presented as educational products. One is composed by narratives from some investigative classes and the other deals with numerical sequences for 7th grade students.
