Object Permanence Box with Tray

This is a traditional Montessori material used to develop hand-eye coordination and teach a child the concept of object permanence - the understanding that objects continue to exist even when they cannot be seen, heard, or otherwise sensed.

Children will also feel a sense of satisfaction when they have mastered the ability to fit the ball into the hole. 

You can begin using this material whenever your child can sit well without support. 

Made of natural beech and walnut. Includes 1 wood ball. 

Dimensions: 9.45" x 4.75" x 3.35"
