Activísimo! is a children's protest workshop aimed at kids aged 4 to 8 whose chief aim is to stimulate and exercise the generation of questions and empower the formation of opinions. The workshop frees the voice and promulgates problems in a free, joyful, emancipatory manner. The first part consists of generating visions, questions and propositions from the perspective of children about the city, about life in common, about school, about their contextual experience. The second part consists of creating relevant banners and slogans and in the third part everyone takes to the street to demonstrate and propose these questions as a jubilant game.
