Well, it's getting cooler outside, which means the sand/water table is turning over to the winter use as a sensory table.
Our fall tub includes-scratch grain (from our chicken supply, and they will get it when we're done), hickory nuts, black walnuts, some felt fall stickers, and some sunflower seeds. I had a metal container sitting around, so that went in, along with a berry picking basket, a scoop, and some other things for them to sift and sort.
Both kids were very into it-this is Zgirl's first time really interacting with a sensory tub as she was too young last year. It gave me a peaceful half hour to fold laundry =)
