The intention of this dissertation is to investigate the attainment of knowledge and development of introductory notions of combinatory reasoning with children between seven an eight years of age. In this sense, we have built a sequence of exercises, based on the Conceptual Fields Theory (Vergnaud, 1990) and on Records of Semiotic Representation Theory (Duval, 1993) starting with concrete situations. Our hypothesis is that the work done in groups can contribute to the development of the activities, as it helps the exchange of information, the socialization of the involved and of the ideas, in addition to the need to justify to ones partner. The development of this research follows the Didactic Engineering (Douday, 1987) presumptions, that is, at first we made a small historic introduction and a survey of what we found in the National Curriculum Parameters (PCN, 1997) and in didactic books, in reference to the theme, research of two publications directly related to the focus of our study. Right after, we built and made a preliminary analyzes of two types of activities for which we confectioned materials, one of which viewed the determination of combinations of clothes and models, using magnetized parts, and the other, the possibilities of different routes, on a checkered board, to reach a determined destiny, based on the launching of an object similar to a coin. After applying them to a group of students, we analyzed the behavior of the pairs, on the procedures and registers they obtained. The results evidenced that the use of manipulative material and the work developed in pairs favored not only the interest for the work proposed, but also the development of organization ideas, reading, counting, and visualization of results and of the first steps in relation to the addition and multiplication fields, fundamental for the development of the combinatory reasoning
