Description of Presentation:
We will discuss with the audience results of three third-grade classroom intervention studies on topics from the conceptual field of multiplicative structures (Vergnaud, 2009), namely, division, proportionality, and functions. The results we report call for changes in the mathematics curriculum and practice.
