The objective of this dissertation was to investigate the possible performance of introducing the entire negative number on the 3rd cycle of the fundamental school in a public organization on replication of part of the Passoni (2002) work so as to respond the following questions of the investigation: Starting from a sequence formed by a familiar and significant context, what is the comprehension that the 3rd cycle school children will have over negative numbers? To what extended level this sequence might aid on introducing this concept? At last, what s this improvement consisted of? On this approach, an interventionist investigation was developed with students of two groups of the 3rd cycle fundamental public school in the city of Sao Paulo; one of them named as the control group (CG) and the other one being the experimental group (EG). The field survey had two steps execution of diagnostic instruments (before and after tests) on the CG as well as the EG group and carrying out the teaching intervention with the usage of manipulative material only at the EG.The results obtained in each of these steps were evaluated considering the possible introduction of the negative numbers to the students of the 3rd fundamental cycle. In theory, we lay down on the ideas of Jean Piaget and Raymond Duval related to the kind of representations that can act upon the Mathematic conception. The target is to make students able to convert intentional treatments of semiotic representations in roughly instantaneous treatments. The results show a 50% increase on student s performance of EG group, at pos test. Taking into account these results, it can be concluded that the associative intervention on teaching with manipulative material has developed strategies for the solution of the activities. The activities were developed with 17 children of EG and 18 ones of the CG. The results are said to be satisfactory
