As for math, there are many alternatives to public and private school.  First are the online courses. Most of the typical homeschool programs (Abeka, Bob Jones, etc) have math products. Another approach is the Saxon math series, which walks a student through the material. (Many people have had success with this approach, but look at the article The Math Problem before going this way)

Let me suggest better approaches. I would strongly encourage you to use a program that has more advanced textbooks and better coverage of the material - namely college level books. Let's face it, when colleges teach algebra it is the same as a high school algebra - except for the expectations. (Once again, see article The Math Problem.)

So here are some solutions.

1. Use a video program that uses college level books. We offer some of these ourselves.

2. Enroll your student into college math courses as either degree seeking or pre-enrollment. Many colleges will allow students to audit courses. The advantage of this approach over entering them into public or private high school is that you are dealing with only one course with limited time in the company of older kids - possibly more mature.

3. Get a teacher from the homeschool community. If you search the local homeschool communities, you might just find the math courses being offered in a homeschool setting. Often these are homeschooling parents who started teaching a subject when their own kids had to take it and the parent had an adequate background to teach the course. Any parent with a degree is science, engineering, or math would be perfect. You might approach a person with these credentials who has children at the same level as yours - they have to teach it anyway!

4. Get a good textbook and find some help. Even if a parent will not be able to teach a course, they may offer help sessions or be willing to be on-call to help. Math is a subject that must be done and not lectured about. Students often can go through the material and just need help to get over certain areas - so sitting in a class might be a waste of time. A little help and a good book might be all they need.

All of the math courses we offer use college level textbooks and our Teacher's Guides explain step-by-step how to create college-level expectations at home. In addition, we offer FREE Homework Help and support to students who buy from us. Check it out :)
