Montessori - Flip Sliding Top Box
While your baby plays with the sliding top box, he’s building hand and finger strength as well as developing his hand-eye coordination. He’s also working on problem solving skills—figuring out how to move the lid to find the ball inside.
Let the ball drop into the hole and ask your baby "where did it go"
Let him watch you slide the lid to reveal the ball.
You can drop other objects in the box or put them in and slide the lid to hide them- your baby will be so proud of himself when he can do on his own.
