Young children learn through their senses. A Casa dei Bambini classroom contains carefully designed materials to let children explore and put names to a variety of sensations: size, color, shape, texture, scent, sound, and more. Children take pleasure in games of organization: sorting or ordering objects, counting beads, etc. Other activities provide physical, tangible introductions to the mechanics of language (parts of speech, etc.) or to concepts of number (the decimal system and basic mathematical operations).
