Trabalho de Curso (Licenciatura em Matemática) – Faculdade de Matemática, Campus Universitário de Castanhal, Universidade Federal do Pará, Castanhal, 2025. Disponível em: https://bdm.ufpa.br/handle/prefix/8302. Acesso em:.https://bdm.ufpa.br/handle/prefix/8302The present academic portfolio addresses the development of my professional identity as a mathematics teacher under the guidance of Prof. Dr. Renato GermanoReis Nunes. It is based on the implementation of three pedagogical projects that employ innovative methodologies and interdisciplinary practices. Each project is grounded in a specific article, as follows: “Mathematical Modeling in House Renting: Price Prediction and Trends” explores the use of mathematical modeling to analyze the time required to purchase a house, considering different rental values. The study connects mathematical concepts to everyday problems, encouraging students to develop practical skills and critical thinking. “Challenges Faced by 6th Grade Students in Learning Fractions: A Solution Based on the Fraction Domino Mathematical Game”, which proposes the use of an educational game to facilitate the understanding of concepts such as ratio and proportion, aiming to make learning more engaging and accessible. “Measuring the Coefficient of Restitution Through Sound Analysis: An Experimental Approach with Mathematical Modeling” presents an experimental method for calculating the coefficient of restitution of balls bouncing on rigid surfaces. Using the app Phyphox, the article demonstrates how low-cost technological tools can integrate physics and mathematics concepts. The three projects presented exemplify distinct approaches to bridging theory and practice in mathematics education, contributing significantly to the development of the educator's professional identity. Each initiative underscores the importance of interactive methodologies, the practical application of theoretical knowledge, and the relevance of connecting mathematical concepts to students' everyday experiences. This portfolio, therefore, demonstrates how reflective practice and pedagogical innovation enhance the educator's role and broaden the horizons for effective teaching and learning in mathematics.Acesso AbertoIdentidade profissionalMatemáticaJogos educativosProfessional identityMathematicsEducational gamesCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICATrabalho de Curso - Graduação - MonografiaAttribution-NoDerivs 3.0 Brazil
