In this work a Mathematical Organization (MO) of reference relative to the notions: limit and continuity of real functions is reconstructed and described. It is proposed for an Economical andAdministration Calculus course, in the first year at University. The adopted theoretical frame is the Anthropological Theory of Didactic (ATD) (Chevallard, 1999, 2001). The mathematical, social, and cultural sense (Bosch et. al., 2006) of this OM of reference is described. Finally, the practicaltechnical and technological-theoretical components of the OM are detailed; this is, the types of tasks, the mathematical techniques, the technologies and theory.
