The Toddler Imbucare Peg Box (I 180-1) is a classic object-permanence and hand-eye coordination material for children in the Infant-Toddler environment, typically used between 12 and 24 months. The child posts a peg through a hole and retrieves it from a drawer, building the understanding that an object continues to exist when out of sight. It is an essential sensorimotor work for early Imbucare sequences and supports the fine motor control that precedes more complex insertion tasks.
