With A, I use things we have around the house. At the moment that's craft ribbon and some of his toys (shapes) which have holes in them. I assist him in pushing the string through a hole, (until he is able to do it on his own since they are super tiny) then we spin it around like a skipping rope. With this activity, not only is he strengthening his fine motor skills and hand-eye coordination but it also reinforces what each shape is as well as colours.
