To do so, a module with teaching activities was elaborated based on constructive teaching. The study consisted of a methodological intervention, done by the researcher, and had as subjects students of the 8th grade of the State School Desembargador Floriano Cavalcanti, located on the city of Natal, Rio Grande do Norte. The methodological intervention was done in three stages: applying of a initial diagnostic evaluation, developing of the teaching module, and applying of the final evaluation based on the Mathematics teaching using Constructivist references. The data collected in the evaluations was presented as descriptive statistics. The results of the final diagnostic evaluation were analyzed in the qualitative point of view, using the criteria established by Richard Skemp s second theory about the comprehension of mathematical concepts. The general results about the data from the evaluations and the applying of the teaching module showed a qualitative difference in the learning of the students who participated of the intervention / O objetivo do presente trabalho foi desenvolver um estudo sobre a escrita e a manipula??o alg?brica de express?es simb?licas para o per?metro e a ?rea de alguns pol?gonos convexos, abordando as propriedades operat?rias e da igualdade, estendendo-se para a obten??o das f?rmulas do comprimento da circunfer?ncia e da ?rea do c?rculo, essa ?ltima a partir da f?rmula do per?metro e da ?rea do hex?gono regular. Para tanto, foi elaborado e aplicado um m?dulo de atividades de ensino, com base em ensino construtivo. O estudo consistiu numa interven??o metodol?gica, realizada pela pesquisadora, e teve como clientela alunos da 8? s?rie da Escola Estadual Desembargador Floriano Cavalcanti da cidade de Natal, Rio Grande do Norte. A interven??o metodol?gica foi realizada em tr?s etapas: aplica??o de uma avalia??o diagn?stica inicial, desenvolvimento do m?dulo de ensino e aplica??o de uma avalia??o diagn?stica final, com base no ensino de Matem?tica de referencial Construtivista. Os dados coletados nas avalia??es foram apresentados sob a forma de estat?stica descritiva. Os resultados da avalia??o diagn?stica final foram analisados do ponto de vista qualitativo, mediante crit?rios estabelecidos segundo a teoria de Richard Skemp sobre a compreens?o de conceitos matem?ticos. Os resultados gerais sobre os dados observados nas avalia??es e na aplica??o do m?dulo de ensino apontaram para uma diferen?a qualitativa na aprendizagem dos alunos que participaram a interven??o
