Great question. The traditional unit study tries to incorporate all of the school subjects into the same topic. So if you were studying Greek history, it would include science, math, spelling words, poetry, etc. all tied into something about Ancient Greece. Sometimes the activities can become a bit far-fetched to try to make them somehow tie in to the topic.
In the CM way, some subjects can naturally fit together, like history and literature or history and geography; but they don’t have to. In fact, Charlotte preferred that we allow children to make most mental connections themselves, rather than trying to give them something with all of the dots already connected. Making those mental ah-ha moments on their own is more meaningful and sticks with them longer.
I’d love to hear others’ thoughts on this concept.
