According to Bail (2002, P. 24) ' ' Allied to the escolaridade, it is the necessity of the appropriation to know relative to the organization of the work and production, since the repetitive and extenuantes functions are being transferred to mquina' '. In this direction, for being in an institution whose pertaining to school activities are come back toward Ensino Technological Technician and acting in the PROEJA in Agroindstria, Maintenance and Support in Computers and Administration, some knowledge must be on. We need to explore the several you discipline, techniques or not, its relations with the Mathematics. We observe the pupils during the lessons of excessively you discipline of the course and we start to visualize possibilities of integration of them you discipline with projects interdisciplinares. The pupils brought proposals that could be transformed into small projects, becoming the learning most significant, since such projects could be associates to its experiences and experiences of work of them. We have as example the projects suggested and executed for the pupils: Cycling and Environment: A health question, the influence of the Associativismo and Cooperativismo in the Agricultural Extension, the mason and the mathematical modeling, the mechanic and the mathematical modeling, the Home of Aged of Ceres and its histories and Cassava: root of roots. These projects had been presented in XI the Fair of Sciences and V Sample of Sciences and Technology of the IFGoiano-Ceres, in October of 2009, of which 3 had been awardees. Some subjects and contents had been argued and presented for the pupils through these projects showing the community what they are capable to produce. This type of activity searched and executed for the pupils is the reply given for them when considered the education of the mathematics that privileged the knowledge brought for them? a continued education, come back toward workers, who already possess a rich experience? making with that they were felt stimulated actively to participate of the lessons and activities proposals.
