The research is qualitative in nature and is focused on the didactic engineering methodology perspective. It was developed in a state school in the city of Parintins / AM and its general objective is to analyze in what aspects a Didactic Engineering favors the mathematical learning of 7th grade students from the Financial Education activity. The results presented come from the analysis of data obtained through an open type questionnaire and systematic observation according to Gil (2008). And it made possible to emphasize that a Didactic Sequence is not done randomly and not just following the script of a textbook, because for its effectiveness it is necessary first of all, to know the reality where the teaching situations, didactic situations, will be developed.Acesso AbertoAtribuição-NãoComercial-SemDerivados 3.0 Brasilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Sequência DidáticaEducação Financeira.Aprendizagem matemática.Trabalho de Conclusão de Curso
