When we started homeschooling a friend recommended the book "Home Learning Year by Year" by Rebecca Rupp. You can check it out at the library or find it pretty cheap on Amazon. It goes through each grade and gives info on every subject with recommendations for books and other resources to use.
As I came to find out, there are lots of ways to homeschool. I suggest doing some research and finding what works for you and your daughter. Being fluid and changing as necessary. There are a lot of books about homeschooling at the library. I read a ton when we were trying to make the decision and I got a little overwhelmed. But I also learned a lot.
I have a 6 year old daughter and an almost 4 year old son. We could get together for a play date or a park day if you'd like to chat more.
