Students learn different subjects in schools and we have different curriculums. The important things are taught in all curriculums. But it is important to learn together and to cooperate and collaborate in discovering important things about history, traditions, customs, nature, being green, save planet... Learning together can be great and it will develop students’ creativity and competences. Students will work in national and international teams. It is an important way to de find out more about traditions, customs and to create interesting things. Finally, they will create a book with traditions and customs and they will invent games and songs and dances starting from traditions. They will create a magic story for happy students and a Green Book- with solutions of saving nature and healthy food.
