This work contributes, on one hand, to determine the didactical implications of an analysis of epistemological works on the association of numbers, calculus and geometry, and, on the other hand, to constitute a theoretical framework favoring the analysis of students’ mathematical work at the meeting point between a mathematical object and its sense in geometry. Our theoretical framework concerns mostly the Mathematical Working Space and the semiotic mediation. The analysis method will be sketched to ultimately present a part of our research results. These results relate to the determination of a personal path resulting from interactions produced among the diverse Mathematical Working Space dimensions. Their produced results draw attention to the obstacles and cues allowing the association of multiplication to certain geometrical significations.
