Investigating the concept of area for teaching and Creativity in Mathematics: interactions based on a story

This paper describes a virtual teacher education forum based on the perspective of Mathematics for Teaching and Problematized Mathematics. The data produced and presented derives from the story Imagined experience: the concept of area straight from the classroom and included multiple resolutions, ways of listening and shifts in the meanings of error and non-understanding. In methodological terms, considering the Development Research, there were indications of the potential and weaknesses of the Training Situation portrayed. In conclusion, the alignment with Creativity in Mathematics was found to be relevant, since it contributed to the mobilization of interactions, favoring the reorganization of Mathematics for teaching the concept of area to participants.
