The mental calculation facilitates problem solving, develops the numerical sense, the ability to estimate, creative thinking and, independently, is a differential in facing problems. Historically, we noticed the presence of mental calculation in pedagogical manuals, teaching programs and textbooks, but we note that it is little prioritized or valued by teachers in the early years of elementary school. This devaluation may be the result of lack of knowledge to teach. As we only teach what we know, teachers who do not know mental calculation do not feel able teaching it. In this perspective, we promoted the course Mental Calculation for Teachers (CalMe Pro), whose objective was to teach mental calculation strategies to teacher, so that they, as protagonists in the classroom, star teaching students. This text reports the experience in the planning and development of the CalMe Pro course. The course showed that teachers who are confident about mental calculation, in possession of the knowledge of the strategies, their use and the way of teaching, feel motivated to insert the strategies of mental calculation in its practice and provide students with the benefits of it.
