This article reports an experience of the development of a task of Modeling (Mathematics) and its projection to the classroom from the reflexes in and the continued formation. From the reflections in the training, the task triggered new research activities and favored the insertion of Modeling in the classroom to explore two main concepts of Mathematics: reason and proportionality through the concept of density.The results indicate the positive evaluation regarding the task developed and projection of the insertion of new practices of Modeling (Mathematics) by the teachers to the teaching action, thus increasing the use of Modeling in Education in the teacher's doing.However, they indicate concern about the fulfillment of the prescriptions, among them, the programmatic contents that are included in the Mathematics curriculum matrix. In relation to the students who experienced the task implemented by one of the teachers, they (re) organized the representations initially textualized and signified the concept of density by verbally expressing the mathematical model. They did so to perform their calculation and to use the concept to make arguments during the development of the task.
