This volume reproduces the successive versions of the VMT curriculum in collaborative learning of dynamic geometry. In consecutive years, the curriculum focused more tightly on introducing teacher teams and student teams to the concept of invariant dependencies, which is central to the theory and implementation of dynamic geometry. The VMT Project developed a collaboration environment and integrated a powerful dynamic mathematics application, GeoGebra, which integrates geometry, algebra and other forms of math in a dynamic computational environment. The project made the incorporated GeoGebra multi-user, so that small groups of students can share their mathematical explorations and co-construct geometric figures online. In support of teacher and student use of this collaboration environment, it developed several versions of a set of activities to systematically introduce people to dynamic geometry, including core concepts from Euclid, standard geometry textbooks and the Common Core Standards for Geometry.
