This Seminar, sponsored by I-MATH, is related to a new european project named INTERGEO, as a sort of preparation meeting among the different partners, some months before the official starting date. The topic of the project is dynamic geometry packages (such as Sketchpad or Cabri, Cinderella and the like) and their use in the classroom for educational purposes. Theidea is not improving existing ones (or building up a new one) but fostering their actualuse, by sharing (cataloguing, testing, documenting) resources, based on these packages, that have been elaborated by so many along the years. The Intergeo proposal can bedownloaded from here. The Seminar is divided in two halves. From Monday till Wednesday, the meeting will focus on the analysis and distribution of tasks for the different WorkPackages and partners of the Project. The second part of the week, the Seminar will adopt Spanish asworking language and will concentrate on the preparation of the Unican team for thetasks it has to deal within Intergeo.
