DS1 is almost 2.5 and for Christmas I made him a 'fun station'. I got a big plastic container lid to hold everything, and put in:
*paints & smocks
*playdough with all sorts of cookie cutters, etc
*different containers full of dried pasta, lentils, beans, and rice (which are all mixed up now!
)
*an assortment of measuring cups, spoons, plastic cups, bowls, and ice cube trays to mix, scoop and sort
The only things I bought were the paint and the containers for the beans, etc., plus the beans and lentils. Everything else I found at home. I made the playdough.
We haven't even gotten to the paints yet, but DS loves scooping all the stuff around!!
I was planning on doing some water play with him too using the same container lid, but we haven't gotten to it yet.
I'm sure a lot of this won't be appropriate for your younger LO, but maybe he'd enjoy painting!
Another thing I let DS1 do and actually a younger toddler could probably do too is scoop flour from one container to another. It's messy, but easy to clean up, and he loves it!
Here's some pics:
