This article presents a master's research process that proposes a field activity as a methodology for the teaching of geometric concepts linked with problem situations. Was carried with students from the 9th grade of elementary, developed from the application of a didactic sequence, divided into three stages. In the first stage, the geometric concepts necessary for the development of the field activity were taught. In the second stage, the field activity was carried out at the Santuario do Lima, where the students solved pre-elaborated problem situations. In the third stage, learning assessment was carried out. Because of the application of the field activity, the students were able to observe and identify geometric concepts present in the buildings of the Santuario. The promotion of critical Mathematics Education, in a non-formal environment was able to collaborate with the formation of reflective students capable of giving meanings to concepts in their reality.
