Acesso em:.https://bdm.ufpa.br/handle/prefix/9841This Course Completion Work was developed in the publication modality, presented in portfolio format, according to the TCC Regulations of the Mathematics Teaching Degree Course at the Federal University of Pará. The study gathers and analyzes three experience reports prepared throughout the initial teacher education, covering different dimensions of Mathematics teaching. The first report addresses the teaching of Spatial Geometry through playful activities, developed within the scope of the Institutional Program of Teaching Initiation Scholarships (PIBID). The second deals with the teaching of linear functions through mathematical modeling applied to the transportation and housing costs of university students. The third presents the mathematical modeling of dynamic systems through ordinary differential equations, supported by computational tools. The objective of this work is to systematize and analyze the academic and pedagogical experiences undergone during initial training, highlighting the articulation between theory and practice, the development of teaching skills, and the construction of a reflective, contextualized pedagogical practice committed to meaningful learning in Mathematics teaching. The integration of the analyzed productions evidences the process of constructing the author's teaching identity and emphasizes the relevance of investigative, contextualized methodologies and the use of technologies in the training of Mathematics teachers.Acesso AbertoFormação docenteEducação matemáticaModelagem matemáticaTeacher trainingMathematics educationMathematical modelingCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICATrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
