That is exactly why I went with an online school. I didn't want all the work of coming up with lessons, etc or spend tons of money buying a curriculum that I had to teach. With online school, there are teachers that do the teaching and the school provides all the books and even a computer. All I have to do is make sure they do the work and enter attendance hours. That, and acting as difficult child 1's para for comprehension and writing.
Good luck. I give you a lot of credit for going the homeschool route.
