Current researches about number construction are recovering the role played by numerical activities (specially counting) in number construction. For most of the authors and other scholars, recent results regarding that subject, if not denying the stage of knowledge reached by the International Center of Genetic Epistemology, they surpass it from the theoretical point of view. In this study, the role of counting in number development according to the Genetic Epistemology is discussed. The contemporary value of the Piagetian theory is pointed out by contrasting it to recent researches results and methodological proposals about the construction of the number concept which are based, almost exclusively, on counting, in order to question if their results or their suggestions would be, theoretically, "beyond Piaget".
