INTRODUCTION the easinesses and difficulties in the learning of the education of the mathematics in the pertaining to school series initial requires practises to consider it pedagogical in the idea of annulling to distort the objectives of disciplines. Done research recently shows that more than the half of the students, when concluding the fourth series of Basic Ensino does not know to make calculation and not even knows the signals of the four mathematical operations. This unsatisfactory performance in school of agricultural zone directly is related to the deficiency in this area of education. If these data are estarrecedor in regular education what if it can wait of a mathematics applied for carriers of special necessities, in such a way, that the education of the mathematics is instrument for so longed for social inclusion. In the attempt to solve these problems congresses are carried through, national and international conference of mathematical education, having as objective a quality education.
The conferences give beginning to a knowledge exchange, of content programmarian of it disciplines and methodology of as to apply. The mathematical boarding is given credit to be the etnomatematica essential the qualified professional formation. Worried about previous knowledge more with the deferential forms of reasonings and also the cultural diversity of the existing groups in a society and taking in account the urgency of the igualitrio social environment forming critical, creative, sensible and mainly participant citizens, defending the use of an adequate mathematics to each one of these groups it not only clarifies us (PUESCHEL SIEGFIED, 1998) Inside of this perspective, knowing itself it variety of questions that intervene with the process teach-learning are that in it takes the necessity to construct a mathematics to them that if adjustment a specific grouping of the carriers of syndrome of Down. Special the physical and intellectual limitations of the carrying child of necessities can be modified, of voluminous reading for the competent manuscript and of the precocious training. The knowledge of the difficulty of learning of this disciplines in the initial series it provided the quarrel of a pedagogical boarding specifies for this case. Ahead of the mentioned obstacles already and generating a mathematics capable to establish mental relations between different situations, it can conclude itself that if the child thinks, creates, invents, constructs numbers, adds etc. is a thought developed for (GOLDSTEIN, SAM, 1990). In the agricultural community still people exist who believe that the child of mental deficiencies does not have to frequent school, therefore have doubt of its capacity to learn. Goldstein played an inquiry work, proving that all carrying individual of the syndrome of Down can learn, to have access to the society as a whole, to study, to play, to work to have normal life as any another person, either it of the agricultural zone or urban zone.
