| Abstract: | I will analyse the individual and collective activities of fourth grade students while trying to explain a schoolfellow's
mistake in the use of a geometrical schema (shared by the class) of the sunshadows phenomenon. The study aims at detecting
productive links between context-related argumentation, mathematical modelling (here concerning sunshadows) and conceptualization
(inclination of a straight line to a plane), as well as discussing their relevance for mathematics education.
