The purpose of this study was to investigate the evolution that could be reached by students of 5th-8th grades in their knowledge of the broad sense of the order relationship arriving before or at the same time as during the delivery of a didactic intervention designed in the light of the theoretical framework of Brousseau. Students were challenged with problems dealing with the arrangement of characters in order of arrival, thus requiring non-numerical order relationships to be handled. For analyzing the answers, elements of Brousseau s Theory of Didactical Situations were employed, along with elements of Machado s investigations on the mechanisms of mother-tongue imbuement and of Polanyi s reflections on the structure of tacit knowing. With the help of these referentials, the answers were grouped into categories, which enabled problem-solving procedures to be observed, in addition to factors that were found to have facilitated or hindered the students search for all the range of solutions. These factors were related to the didactical contract, to mechanisms borrowed from the mother tongue, and to influences derived from other fields of knowledge. Results revealed that despite their lack of previous practice with problems having multiple solutions or with those involving non-numerical ordering, students were able to evolve in their knowledge by experiencing the teaching sequence delivered to them
