Curious and excellent researchers in individual activities as in group, the organization of the research projects and in its presentation had revealed in such a way. Thus, we saw that he is possible that the school contributes positively for the formation of more critical, creative and independent citizens, responsible for its conquests, better prepared to participate of the transformations that have occurred in the world of the work. . We understand that the Mathematics must be inserted in the conquests of these pupils, acting of significant form, giving to emphasis to the orality in all the moments and always tied with the social necessities of these citizens. Kuenzer (2007) speaks on necessity of the school, in special the professionalizing one, to adapt it the new requirements of formation of the worker: (…) a new project, where the repetition, the memorization, (…) is substituted by the domain of the communicative abilities, for the logical reasoning, the capacity to discern, to create, to commit themselves, to work with the information, to construct original solutions, and, mainly, to doubt, of not being pleased e, in result, to educate itself continuously. (KUENZER, 2007, P. 66) We perceive then, the necessity to develop for this pupil-worker an environment to stimulate its reasoning and that it favors the understanding of the Mathematics encircles that it. We use during the lessons information found for the pupils in pamphlets of store and supermarkets, periodicals, magazines of weekly circulation, notice of the Internet, accounts of water and light, stub-books and others. We determine a moment of the lesson so that they presented the colleagues what they had brought for lesson, another moment for the elaboration of problems in groups, and later we made the caster of the problems as form to socialize them and to discover other possible forms of resolution. To develop the critical sense, the respect, solidarity and the autoconfiana in its speeches we promote debates using brought up to date texts that said of the reality politics and social and from there we extract situation-problems that would have to be argued in group and to be presented to the too much possible groups solutions to the questions that them were proposals.
