You really need to educate yourself on what’s out here in homeschool world. Just about everything you propose already exists! Coops (mom’s rotate subjects) and small groups, plus an abundance of online video (live and/or taped) all meet the goals.
Well, it needs to be repeated time and time again, because I know many who are clueless.
So If I am repeating what is out there, then good.
I’ll keep doing so, until everyone wakes up to it, because I have people ask me every day about it.
