MyMontessoriBox_Box object permanence

EDUCATIONAL OBJECTIVE: to understand the notion of object permanence. This pretty wooden box has a tray that allows the child to recover the ball he has just dropped. The top of the box has a hole corresponding to the shape of the ball to be embedded. After embedding the ball, it reappears on its own on the board in front. He can then retrieve it. The disappearance and reappearance of the ball calls the child's attention and makes him clearly assimilate the notion of object permanence: even if he no longer perceives the object, it reappears.
