For Art, we used Chalk. This is the first time we use chalks. I put this off for some time as they were still very into tasting things. Though they were still tempted to do so, I managed to stop them. I think it's a good sensory material too. Y&K were quite intrigued with the powder that comes off the chalk, though K didn't really like the feel of the powder on his hands. I introduced Curved and Straight line to them with this activity. Here's their scribbles, the thick curved and straight line by me.
