For the development of algebraic thinking, it is essential to use methodological teaching strategies to develop algebraic skills in students, with a view to produce meanings to the objects of knowledge of algebra. The research aimed to investigate activities organized in a didactic sequence that addresses the concepts of polynomials and their operations for students of the final years of the Elementary School, from the perspective of the National Common Curricular Base. This investigation adopted a qualitative approach, with a characteristic design of a case study. The analyzes of the productions carried out by the students of a state school in the city of Manaus, state of Amazonas, together with the observations and recordings of images during the application of the sequences of activities pointed out that the accomplishment of tasks organized in a didactic sequence allied to the methodology Problem Solving and mediated by the use of concrete material as a didactic resource aroused the students' interest in the activities and contributed to the development of characteristic elements of algebraic thinking, as it allowed the gradual construction of meaningful mathematical concepts. In addition, the organization of teaching work in the classroom contributed to the development of social and emotional aspects in students.
