This study focuses on mathematical knowledge for combinatorics teaching in basic education. According to the research literature in Mathematics Education, this topic is generally difficult to be understood by students (MOREIRA, ALVES, MAGINA, 2013) and a relevant topic for the mathematics teacher education (BORBA, 2010). In the light of the notions of Mathematical Knowledge for Teaching (BALL, THAMES, PHELPS, 2008) and Pedagogical Content Knowledge (SHULMAN, 1986), we outline a methodological itinerary of qualitative character, which consisted of sending a triggering problem – The Different Ways Problem (ANDREESCU, FENG, 2013, SILVA, 2017) – to different mathematics teachers through a broadcast list of the WhatsApp application, inviting them to reflect on resolution strategies for students in the classroom. Thus, our objective was to analyze these resolutions and discuss their knowledge, according to conceptual, didactic and pedagogical aspects. From this point of view, we verified that the teachers mobilized the different aspects of Mathematical Knowledge for Teaching. Finally, in simulating the resolution of this problem for the students, we found that the teachers were also able to resize (and reflect on) their knowledge, evidencing that they learn and theorize during their practice.
