This book gathers the ideas I presented on 12-16-2018 (my birthday) under the title of Attractive projects, in the seminar Classroom experiences with GeoGebra, held at CIEM (International Centre for Mathematical Meetings, Castro Urdiales, Spain).
One of the challenges that a maths teacher have to face when he wants his students to learn how to make GeoGebra constructions, is to decide what kind of projects he can propose, as well as what are the keys to their development.
What kind of "geogebraic" projects can be attractive to students? What prior information should we provide them so they can address them?
I will present some ideas that can be classified into three groups: Design projects, Model projects and Robot projects.
In all of them, the notion of "movement" will be esential, both from the mathematical point of view (vectors and parametric equations) and the use of GeoGebra (sliders, paths, automatic animations and GeoGebra scripts).
In addition, I will be offer undocumented technical information (in Spanish) on parametrizations of the loci used by GeoGebra.
