Tasks are central elements in our professional practice. Its implementation requires teacher’s knowledge concerning their potentialities and limitations aimed at leading to students’ mathematical learning. Considering teachers’ knowledge as specialized – here, assuming the Mathematics Teacher’s Specialized Knowledge (MTSK) – leads to the need for an innovative approach in the way pedagogical resources are understood; the specialized knowledge involved in its use and the specialized set of indications for its implementation. In the work we developed at CIEspMat – Grupo de Pesquisa e Formação sobre o Conhecimento Interpretativo e Especializado do professor de e que ensina matemática – as part of the so-called Tasks for Teacher Education (TpF) – we present a conceptualization of tasks for students including a set of five dimensions corresponding to guidelines for the implementation, pursuing the mathematical learning associated to its conceptualization. Here, we focus on a task for students (perceived as a resource), focusing on the topic of proportionality, discussing the content of the five dimensions composing the specialized guidelines aimed at developing the students mathematical understanding.
