I first read about circle painting here, though I've seen it on several blogs since then. I liked the idea of a collaborative project, and decided to use this project with my pre-k through first grade. I would certainly do this project again, with any grade level, though it worked out better with first grade than the younger groups. This was really just due to a few students in class, who are on the more messy side. Some of the other students were more likely to get frustrated at this grade level. The students were very proud of their work.
