I'm not what you call this sort of activity, but my boys love it. Oren will spend several minutes taking the clothes pin out of the bucket and putting them into the canning jar. He will also take the clothes pins and stick them in toys, our change jar and any other hole he can find.
Finnegan and Oren also love to put the dominos (sometimes they are tickets or money) into the wipes container. Dominos are great for counting and they make a really neat sound when they bang together. Oren can usually be found with a domino sticking out of his mouth or a domino in his hand while he looks for an appropriate hole.
