Do you know what to do when you feel sad, angry, or scared? In this project, preschool and primary school students from different countries will collaborate to create an "Emotional First Aid Kit." Using active learning methodologies and a multilingual approach (Spanish, English, French, and native languages), each school will become an "Emotions Specialist" and propose creative challenges (stories, songs, art) to the other participating schools. The final result will be a toolbox, both physical and digital, for managing our emotions in the classroom.
