From a strict cultural-historical perspective, the objective and subjective sides of mathematics are but manifestations of a higher-order…

Geometry, classification, and the classification of geometrical objects are integral aspects of recent curriculum documents in mathematics education. Such curriculum documents, however, leave open how the "work" of classifying objects according to geometrical properties can be accomplished given that the knowledge of these properties is the…
