Serio - prisms wide/ narrow

Size Matching Set - Narrow and Wide helps children understand size and width differences through hands-on learning in schools, kindergartens, nurseries, and learning centers. Children interact with pieces of different widths to identify narrow and wide through observation, comparison, and arrangement. This activity supports visual discrimination, focus, logical thinking, hand-eye coordination, and early math concepts in a simple and direct way, making it suitable for discovery corners and calm individual classroom activities.
