The agroforestry system is an alternative of agricultural production associated to the cultivation of trees that reduce the devastation of nature. Through this research, possibilities of minimizing environmental impacts in agriculture were studied, based on the use of mathematical knowledge. This research has a qualitative approach, initially consisted of the application of questionnaires with open and closed questions to ten teachers and twenty students of a Technical Course in Agropecu?ria Integrated to High School in Par? Federal Institute of Education, Science and Technology, Marab? Rural Campus. During the development of the research several educational practices were carried out; In these activities, the students participated actively and in the end the action and its importance in the agricultural context was reassessed, always trying to enable those involved to perceive the importance of the knowledge built in the school in the daily activities. The objective was to investigate the view of both regarding the importance of educational practices developed in the agricultural context and the use of mathematical knowledge to reduce the damage caused to nature, particularly the agroforestry system. The results point to the importance of mathematics contents, articulated with the other areas of the curriculum, in the search for alternatives that reduce the environmental impacts on agricultural activity. / A agricultura ? uma das atividades que mais tem impactado o meio ambiente nos dias atuais. Produzir alimentos de forma que reduza o impacto causado a natureza ? um desafio a ser superado. O sistema agroflorestal, ? uma alternativa de produ??o agr?cola associada ao cultivo de ?rvores que reduzem a devasta??o da natureza. Atrav?s desta pesquisa, foram estudadas possibilidades de minimizar os impactos ambientais na agricultura, a partir do uso do conhecimento matem?tico. Esta pesquisa tem abordagem qualitativa, consistiu inicialmente na aplica??o de question?rios com perguntas abertas e fechadas a dez docentes e vinte discentes de um Curso T?cnico em Agropecu?ria Integrado ao Ensino M?dio do Instituto Federal de Educa??o, Ci?ncia e tecnologia do Par?, Campus Rural de Marab?. Durante o desenvolvimento da pesquisa v?rias pr?ticas educativas foram realizadas; nessas atividades os estudantes participavam ativamente e ao final foi reavaliada a a??o e a sua import?ncia no contexto agr?cola, procurando sempre possibilitar que os envolvidos percebessem a import?ncia dos conhecimentos constru?dos na escola nos afazeres do cotidiano. O objetivo foi investigar a vis?o de ambos em rela??o a import?ncia de pr?ticas educativas, desenvolvidas no contexto agr?cola, e o uso dos conhecimentos matem?ticos para a redu??o dos danos causados ? natureza, em particular ao sistema agroflorestal. Os resultados apontam para a import?ncia dos conte?dos de matem?tica, articulado com as demais ?reas do curr?culo, na busca de alternativas que reduzam os impactos ambientais na atividade agr?cola.

The study is based on the constructivist sociointeractionist approach to teaching Mathematics and it constitutes, in itself, a methodological intervention with the teachers-trainees engaged in the Professional Qualification Program in Basic Education of the Federal University of Rio Grande do Norte. The foundations of the study were found in investigations of researchers who had carried out studies on the construction of numerical writing, showing, for instance, that the construction process of ideas and procedures involved in groupings and changes to base 10 take a lot longer to be accomplished than one can imagine. A set of activities was then elaborated which could not only contribute to the acquisition of contents but that could also make the teachers-trainees reflect upon their teaching practices in the classroom so that in this way they will be able to elaborate more consistent didactic approaches, taking into consideration the previous knowledge of the students and also some obstacles that often appear along the way. Even when teachers have access to the most appropriate dicactic resources, the lack of knowledge of the content and of the real meaning of that content make the Decimal Numbering System, a subject of fundamental importance, be taught most times in a mechanical way. The analisys of the discussions and behaviours of the teachers-trainees during the activities reavealed that they made them reflect upon their current practices in the classroom and that, as a whole, the aims of each of the activities carried out with the teachers-trainers were reached / O presente estudo tem como quest?o central identificar o conhecimento epistemol?gico que os professores-alunos possuem a respeito das caracter?sticas (propriedades) do sistema de numera??o decimal, e tem como finalidade oferecer uma contribui??o para a pr?tica pedag?gica dos professores que atuam nas turmas de Ciclo B?sico de Alfabetiza??o, tanto no que se refere ? aquisi??o de conte?dos quanto ao aprimoramento de conhecimentos que os auxiliem na elabora??o de estrat?gias adequadas para o trabalho com o Sistema de Numera??o Decimal em sala de aula. O estudo est? baseado na proposta construtivista sociointeracionista para o ensino da Matem?tica e se constitui numa interven??o metodol?gica, com os professores-alunos ligados ao Programa de Qualifica??o Profissional para a Educa??o B?sica da Universidade Federal do Rio Grande do Norte. Buscaram-se fontes de sustenta??o em investiga??es de pesquisadores que realizaram estudos sobre a constru??o das escritas num?ricas, mostrando, por exemplo, que o processo de constru??o das id?ias e procedimentos envolvidos nos agrupamentos e trocas na base 10 leva muito mais tempo para ser realizado do que se pode imaginar. Foi elaborado um conjunto de atividades as quais pudessem n?o s? contribuir para a aquisi??o de conte?dos, mas fizessem os professores-alunos refletir sobre suas pr?ticas em sala de aula, para que, assim, eles pudessem elaborar propostas did?ticas mais consistentes, levando em conta os conhecimentos pr?vios dos alunos e alguns obst?culos que se interp?em nessa trajet?ria. Mesmo o professor dispondo dos mais apropriados recursos did?ticos, a falta de dom?nio do conte?do, do real significado desse conte?do, faz com que o Sistema de Numera??o Decimal, tema de fundamental import?ncia, seja ensinado, na maioria das vezes, de forma mec?nica. A an?lise das discuss?es e o comportamento dos professores-alunos durante a realiza??o das atividades revelaram que estas provocaram reflex?es sobre as pr?ticas de sala de aula como tamb?m que, de modo geral, foram atingidos os objetivos propostos em cada atividade realizada com os professores-alunos
