Virtual school?
I live in Florida and my 3 children do a virtual school called Connections Academy. It is a program that was offered through the state but now is offered by my county (same program).
For me, it puts together all the flexibility and parental control of homeschooling, but the support of a curriculum already mapped out, teacher support and an organized way to keep track of what my kids are doing and it is free to Florida residents.
They gave us a computer, printer, lesson plans, books, art supplies and science lab supplies. They also offer electives. The kids have regular teachers who do "live lessons" every 1-2 weeks and are available for help, but they are not intruding on your day to day school work.
I don't know where you live, but you might try and see if some sort of virtual schooling is available to your state. I know Connections is offered in California and several other states, so they may be in your state.
Virtual schooling isn't for everyone, it is a commitment from me because I am the "Learning Coach," also known as the person who makes sure it all gets done on time. That means I am doing it with them on a day by day basis instead of a teacher. But, it works very well for my family!
