I'll see if I can offer a few suggestions and hopefully some others will chime in soon. We've homeschooled from the beginning, so my perspective may be a bit skewed on some things, as we have not dealt with coming out of public school. I have one going into 11th and one starting high school in another year, plus 4 younger ones.
This is what I would do:
1st: Check into your state's homeschooling laws if you haven't already. Things such as record-keeping, curriculum guidelines, required subjects, attendance may or may not have an impact on your choices. HSLDA's (Home School Legal Defense Association) website I think has that information.
2nd: Consider if you would feel more comfortable with a packaged curriculum that has everything spelled out for you & DD as far as subjects/books and lesson plans. Or are you comfortable doing that yourself? Would you/she prefer all subjects from one company or would you/she prefer to find curriculum that suits her learning style/needs individually for each subject?
3rd: Once you have a fairly good idea of that, then you can check out
HomeSchoolReviews.com -- Homeschool Curriculum Reviews which allows you to search by subject and curriculum. People who have used the various curriculum can write their opinions about it. It is not all inclusive, but there are quite a few there. I use that site to get a feel for how the curriculum works and to get an idea if it is something we could use.
4th: Also keep in mind outside activities that could count as schoolwork too. For example, my kids are in 4-H and they are getting speech-writing, public speaking, interview skills, critical thinking (judging events which require them to clearly state their opinion and be able to back it up), research skills (for their projects), plus many others.
5th: When it comes time to purchase your materials, keep in mind that you do not have to buy new. In my area we are fortunate to have many used curriculum sales, a homeschool resource center which carries used curriculum, and there are online websites that have used curriculum. I usually decide on curriculum and then look for it used, and only as a last resort will I buy it new.
Hopefully this will at least give you a place to start.
