I may be able to help a little depending on what state you are in. Each state has requirements on how to remove a child from public school and each state has its own requirements for documentation etc for you home schooling her. If you want to pm your state, I can see if I can help with this. I can Google lots of different things to aid you. Here is a start of free online 5th grade curriculum:
5th grade curriculum
We home school kiddo, BUT she has always been home schooled, so no school paperwork needed. Also, my kiddo has numerous learning issues, so we teach mainly reading, writing, natural sciences, life skills math, only relevant history, and government. We do not use a traditional curriculum because kiddo does not learn traditionally at all.
