"Sen Dodo" project is a creative space for teacher discovering their first project with the support of ambassadors, within the onsite bilateral seminar in Poland, January 2024. This project will allow us to explore the topic of well-being, with a focus on one of its factors - importance of good sleep. After all, good sleep is needed by everyone - human beings, all living creatures, and nature itself! Through cross-curricular collaborative activities, such as creating a lullaby, a snoring orchestra, sound painting, or guessing moon dialogues, or singing together in English, children will develop competences in Literacy, Art, Maths, as well as social relations.
