Object Permanence Box with drawer is a beautifully handcrafted wooden toy includes a wooden ball and a wooden box with a drawer. Object Permanence Box with drawer is a classic Montessori material that is introduced to infants once they can sit up independently, at approximately 6-12 months of age. This material aids in the child’s development of object permanence, while also honing their hand-eye coordination, fine motor skills, focus, and concentration. BENEFITS: To use the object permanence box, an infant places a large wooden ball into a hole located on the top of the box. The ball momentarily disappears into the box, but then reappears as it rolls out where it is then easily retrieved by the infant. Although the ball fit in the hole in every position, your child needs to open the drawer to retrieve the ball, it doesn’t just roll out. A baby who is still actively developing an understanding of object permanence will often engage in long periods of repetition with this task, until mastery is achieved, Babies like to play peek-a-boo for a reason! Watching their favorite face or toy disappear from sight and only reappear after a while is very attractive because it naturally attracts their evolving understanding of the persistence of objects.
