Environmental education is present in the most diverse segments of society, in our daily lives, in official documents and schools, in private institutions or non-formal education spaces. Formal, non-formal and informal education appear in scientific literature as antagonistic, as if they were competing for space in the lives of students and educators, but in our understanding these nuances of education are complementary to each other, as formal education does not meet all the demands of contemporary times, just as non-formal and informal education alone do not account for the human dimensions and the relationships that humanity establishes among itself and with nature. A study was conducted by listening to teachers, with the aim of understanding how they approach socio-environmental issues in a public school in Recife. Subsequently, interviews and participant observations were carried out in order to collect and construct the data that were analyzed according to discursive textual analysis - ATD. Through various dialogues, inspired by Paulo Freire, we saw how environmental education is present in schools, the relationship between the school and the square, as well as the strategies thought up by teachers so that these two spaces can relate to each other.
