In this work, we reflect over an experience of geometric modeling of brand logos that is developed in the educational perspective according to Kaiser e Sriraman (2006), classified as intermediate between the second and third levels, considering the relationship between Mathematical Modeling and curriculum developed by Barbosa (2001). We aim to identify the character of discussions between teacher and students and the steps that made up the learning environment, and analyze how students make the first contact with Analytical Geometry contents from previous knowledge about functions and exploration of resources. of a computer program. We observed the dynamics in a high school classroom focusing on the teacher's and students' performances during the dialogues in this learning environment. We registered evidence that: the discussions were mathematical or technical, with priorities for the first category. The teacher's performance, in line with Pedagogy of the Question, favored the autonomy of the students, who developed the task with some degree of independence, connecting previous knowledge and new experiences and, despite some difficulties, left the comfort zone of closed and well-defined activities
