The logistics of that project were simple, and because I only had 6 kiddos working on it it was even EASIER! I had 12 colors of paint. I assigned each student one color of paint, and they had 2 minutes to paint circles. After 3 minutes they handed the paint to the person to their right until we had gone through all the paint colors!
The following week I gave each of them their own large paper (18x24) and did the same thing with the paints and brushes so they could make their own paintings. These are currently hanging in my room and they look amazing!
