I chose to use only 2 colors of paint, because at this stage he still mostly ends up rubbing all the paint together; which if I had added blue we would've ended up with brown art.
I put the paint in one of those cheap paint palates. I already had it from college. You could use a plate, next time I will.
I used a heavy cardboard on the floor. I used to pin them up, but if Will was too fast it could knock the pins out. So the floor worked fine. It was easier to clean up too.
Here is the masterpiece! You can't really tell it's shape sponges, but that's to be expected at his stage. We did, however, get to talk a LOT about shapes. Even things I didn't expect to happen. When you hold the triangle on it's side, it now makes a rectangle shape. You can roll the circle & make a track.
The greatest part was Will helped with the clean up & it was a learning experience! I put him in front of the bathroom sink with warm water & asked him to squeeze the sponges under the water. I went to make lunch & I had to pry him away from the sink to eat lunch.
I already have more ideas for how to use these sponges.
