I have a goal to post what "J" is doing, so that when "S" gets to be the age she is now, I don't have to figure it out all over again. So, this hasn't been all we've done, but it's a start...
Clothes pins on a cup. These were mini-clothespins, so they came apart more easily. She like the activity, though.
I put a bunch of containers with lids in one of her boxes. She loved it! It was her #1 choice all week.
Jenga blocks. She sorted, stacked and built. Not a favorite, but it was chosen a few times during the week.
