Our co-op does CM methods for artist study, composer study, and nature study. For an artist, what about someone like Picasso or Monet or someone who didn’t do “controversial” pictures? For composer, there is Bach, Vivaldi, Beethoven… Bach’s background is very mild – Christian, family guy – we just read that book, and the kids would hardly let me put it down. 🙂 I haven’t read the other ones yet. My kids are still very little. For nature study, in the winter anyway (we just joined), they will bring in things for the kids to draw/paint. One week they did fruit (apples, oranges, bananas), and this last week they brought in rocks with fossils in them. Snail or seashells would be fun to do, as well. Or bring in some leaves when it gets warmer, or flowers.
HTH!
