Main objective of the project "Class of peace - level catching game" is to increase cooperation, tolerance and understanding in class through groupwork and other non-formal education elements. We also aim to train youngsters initiative and enterpreneurship, to awake citizen activity and increase solidarity and tolerance between different layers of society. Level catching game is about monthly tasks that classes have to find solution to. Tasks are creating picture of the class, making the map of different talents class has, writing essays about good things in classmates and so on. All tasks are composed so, that class could develop as one collective, that cooperation among class would be as big as possible and that there would be maximum learning experience.
