Screw - Unscrew
This one is a very simple activity to keep your child engaged. This can be done with an empty water bottle or any other container that has a screw-able lid.
Take away points for the child:
Having grip in holding a cylindrical shape
Learning which way to turn for open and close
My A keeps exclaiming 'Open!' 'Close!' as she repeatedly does the screw-unscrew action.
