Materials and activities are designed to support self-directed discovery and learning, and so are a perfect match for this developmental stage. They are organized around Practical Life activities that develop both independence and social skills; Sensorial activities that refine sensory perception; the development of Spoken Language, Writing and Reading skills; and Mathematical activities that develop fundamental mathematical concepts; as well as activities that reflect upon our human understanding of geography, history, biology, science, music, and the arts. The trained adult guides the children along this journey, helping them become well-adapted individuals, ready to take a positive, pro-social place in their world.
