Summing up, the most part of the teachers feel that the project has responded to their expectations and found interesting the tasks. They also are convinced that collaboration among students and teachers has been effective. The competences that we think our students have developed the most have been mathematical and cultural awareness and expression. All teachers feel happy with the work, but they had to face up some problems with dissemination and some collaborative works because of the earthquake in Turkey, the tragedies in Serbia and the difficulties with the new platform. However, despite all of these problems and the differences in ages and cultures, we are very proud of the results. The word "diversity" could represent our project motto. We have worked hard with our pupils and we always had the support of the families and schools.
