Hi Bryan (and other "homeys"),
Two resources for you.
1. For 10 years, I was the local school's resource teacher for the 1-2 dozen children doing home-based learning in my small community. Most of the parents and I believed that Life is the best curriculum and Nature is the best teacher. Here's our old blog:

2. My other hat is Sustainability Education Coach and Consultant with GreenHeart Education. Here's my page on homeschooling:

Enjoy! And know that, because of the climate / oceans / biodiversity emergency, the most important curriculum for young people right now is learning how to grow their own food, build their own soil, collect their own rainwater, and generate their own energy (sounds like permaculture!) -- all things they can be learning along with their parents and/or teachers. Everything else in a more academic curriculum now needs to be in service to the Earth, the Future, and the Children ... of All Species ... and that includes reading, writing, and numeracy.
