I found that looking for a local co-op gives you the best of both worlds... support for mom/teacher and a “real school” type atmosphere (changing classes, etc.).
From that, you get great ideas for low cost curriculum. At our co-op, people brought in curriculum they didn’t want and had it available for free. Also, the relationships definitely make a difference as you learn from those who have gone before you.
Ditto on everything Reddy posted. Our local co-ops were wonderful, with all the same benefits Reddy mentioned.
