The proposal is to insert in high school the derived as rate of variation and from there to solve optimization problems, without defining the derivative formally. The problems proposed in this work meets the dynamic in the classroom, concrete problems, with some occurrence in our daily lives, may also include the areas of economics, engineering and physics. / No presente trabalho abordaremos problemas de otimização envolvendo funções polinomiais de grau maior ou igual a 2, onde utilizamos a taxa de variação na obtenção de extremos, que podem ser máximos ou mínimos relativos. A proposta é inserir no ensino médio a derivada como taxa de variação e a partir daí resolver problemas de otimização, sem definir a derivada de maneira formal. Os problemas propostos neste trabalho atende à dinâmica de sala de aula, sendo problemas concretos,com certa ocorrência no nosso cotidiano, podendo ainda abranger as áreas de economia, engenharia e física.
