Intelligence Box. It is a classic Montessori-inspired educational tool designed to help toddlers develop essential cognitive and physical skills through play. The toy consists of a sturdy, six-sided wooden box with various geometric cutouts on its faces. Children must identify and match colorful, chunky wooden blocks to their corresponding slots, allowing the pieces to drop inside with a satisfying sound. Most versions include a slide-off or flip-top lid, making it easy for little hands to retrieve the blocks and start the game again
