Provide opportunities for the children to discover treasures by opening “secret” treasure boxes.
The adult places one or more locked boxes in the dramatic play area. Put fun items in the boxes related to the dramatic play theme and have keys available to open the boxes (or, better yet, give clues for finding the keys).
The child takes small key, places it with an accurate orientation in a lock, and rotates the wrist with appropriate force to unlock the lock.
Children love opening locks, so early childhood educators and parents who include opportunities for use of lock and key have a strong motivator for practicing fine motor skills. Parents can let children use a key to unlock the door when coming home and provide a “secret” locked diary for drawing in and practicing writing.
