If it were ME, and I wanted to include Bible, I would use the SCM history modules.
For language arts, I would have to get realistic. The only thing, *I* would be able to handle with that crew is Alpha-Phonics REVISED, followed by Learning Language Arts through Literature Yellow-Gold. I would lose my mind if I had to break up language arts into separate subjects.
I would use the Tiner science books and some Great Courses videos for the older children for science, but many people would not find that rigorous enough. But that is what *I* would do. I would include the older children in what I did with the youngers, unless I knew they had mastered that material. I would use a combination of Mr Q which is going on sale for 1/2 price in a couple days, and Great Science Adventures, and lots of whatever real books and videos I could get my hands on. My preference of the Tiner books, to use with the SCM history modules, for the older children is:
Module 1: Astronomy
Modules 2: Medicine
Modeule 3: Earth
Module 4: Biology
Module 5: Chemistry
Module 6: Physics
I’d be pretty relaxed about the science, and if the children were reading biographies and non-fiction, and watching Bill Nye and Magic School Bus videos and documentaries, I wouldn’t worry too much about completing curriculum. I’d list the above curricula on reports to authorities, and use just enough of them not to be lying, but I just wouldn’t stress over science.
The easist math I know to use with a large group is the Amish Study Time series. Rainbow Resource now sells Amish math, and so does Milestone Books. *I* would use Saxon Algebra 1 and 2 (half a book a year) for high school as that is what I have been using since the 90’s, and I am familiar with it, but there may be better options now, for someone just jumping in.
This isn’t necessarily the most CM way to do things. And every teacher has her own strengths and weanesses and ways of doing things. I can only tell you what I would do.
I now only attempt to prepare students for junior colleges, not selective 4 year colleges. I have to be realistic about what I can and cannot offer to students. Been there, done that, in over extending myself, and it didn’t accomplish anything other than stressing me out.
