Hi-
I'm not sure how much help I can be with the transition, assuming you're planning to re-enroll her in 9th grade next year, but this link might help:
http://www.aps.edu/home-school/There's no set curriculum you have to use to homeschool your child, and many homeschoolers piece together their own set of books and resources to create their own "curriculum." But if you want to follow the same work she would be doing in middle school, here's a link to the NM state standards expected of each grade in each subject:

If you'd like to talk more in detail with other homeschool parents and get more suggestions, you can always stop by our weekly parkday! Check the scrolling news at the top of the main forum page (
