<< Objectives >>We want to create a partnership between three European schools and share experiences around the school and family life of the children of our territory, the importance of its preservation and the pleasure of learning and sharing together in a foreign language.<< Implementation >>Virtual and physical mobilities will enable teachers to learn from each other’s professional practices and will enable children to discover and exchange on the particularities of their territories in sustainable development projects. The use of digital competencies will facilitate the learning of a foreign language.<< Results >>The teachers have observed and learned from other professional practices, they have learnt to work together and gained in confidence to be able to set up other European projects. The children have discovered their territories (by bike, on foot) and how to preserve them. They have learnt to use another language in a concrete situation to be able to share their experiences. They have used digital skills to gain awareness of the world around them.
