The work has shown promise in identifying a strong tendency of mathematics teachers in this region promote their practice in teaching Plane Geometry, highly influenced by a process algebrization this science and its teaching. This study aimed to promote reflection on the current teaching of Plane Geometry in elementary school in the metropolitan area of Rio de Janeiro, as well as provide a strong tool to minimize disability in its teaching. It is speculated, with strong evidence, that the abandonment occurred in Brazil, particularly in the region where the study was promoted, the use of Geometric Constructions in teaching plane geometry is, perhaps, the main factor that affects the teaching and learning of this discipline. / O presente trabalho foi realizado em tr?s etapas, que s?o parte te?rica, pesquisa com profissionais de educa??o (professores de matem?tica da rede p?blica da regi?o metropolitana do Rio de Janeiro) e realiza??o de atividades diagn?sticas e pedag?gicas na Escola Municipal Cruzeiro do Sul, Mesquita, Rio de Janeiro, com alunos do 6? ano do ensino fundamental. O trabalho mostrou-se promissor ao identificar uma forte tend?ncia dos professores de Matem?tica dessa regi?o em promoverem sua pr?tica pedag?gica, no ensino da Geometria Plana, altamente influenciados por um processo de algebriza??o desta ci?ncia e do seu ensino. Este trabalho teve como objetivo promover reflex?es sobre o atual ensino da Geometria Plana no ensino fundamental da regi?o metropolitana do Rio de Janeiro, bem como apresentar uma forte ferramenta para minimizar a defici?ncia no ensino da mesma. Especula-se, com forte ind?cio, que o abandono ocorrido no Brasil, em particular da regi?o no qual o estudo foi promovido, do uso das Constru??es Geom?tricas no ensino da Geometria Plana ?, talvez, o principal fator que afeta o ensino e aprendizagem desta disciplina.
