Treballs Finals de Grau d'Enginyeria Informàtica, Facultat de Matemàtiques, Universitat de Barcelona, Any: 2017, Director: Anna Puig PuigThe main goal of this project is to implement a 3D video game where primary school students would learn and improve their knowledge about geometric figures and their locations in the 3D space. Specifically, it goes in depth in the Geopieces game modes, creating new diverse educational activities from a new type of game that will be created. Its main objective is to join 3D figures, which were obtained in the previous activities, in order to build a new 3D solid figure. Another important point is to connect Geopieces games with the server that had been developed initially for the Fracsland game. Therefore, teachers would be able to create new type of missions, edit their learning competences and their helps. In addition, they would have the possibility to customize and to follow the progress of each student.
