My J.. oiy,oiy.......... what a decision. I have tons of advice, but you are the only one that can make the decision.
You will go through curriculum like crazy. You will find things that work, that doesn't work. You will pull your hair out in the beginning, second guess yourself, and find that in the end; it may just be the best thing you ever did for you and your child.
I pulled my daughters out of middle school and started homeschooling. I didn't know if I could do it or not, but I thought, I am their mother, and who really knows them best?? ME!! And who is really responsible for their education and well being?? ME!!!
At first we read, a lot. We read everything we could get our hands on. Newspapers. We unschooled first. Then we started a schedule slowly. We did field trips as we wanted to, and there are places that let homeschoolers come in as a group of students at discounts. I took my daughters where ever I could. To me schooling isn't just a classroom, it's culture, art, seeing history, etc.
I used a mix of curriculum. Not just Christian. I liked some of this, and some of that. I really liked the Rosetta Stone foreign language. There are some homeschooling sites where you can swap or buy and sell used during the year also. My daughters did virtual classes online also. When my oldest reached 16, she did dual enrollment at the community college.
I say research, plan your year, check out what your child should be learning. There are retired teachers that will help you. The Dept of Education has those resources to help you as well.
The beauty of homeschooling is the independence and also the freedom to make the choices. You will have so much time during the day to do other things, which will be learning adventures also. Incorporate learning into everything you do. Cooking, sewing, visit farms, learn about agriculture, the extension offices are great for learning. Take up a photography class, make a scrap book. There is so much you can do. We never got around to doing it all. I wish we had. Just wait and see, you will be loving it and can hardly wait to plan the next schedule. Just be patient, and remember, everyday is a learning experience for you and your child.
We all have days we want to goof off. It's okay too. Turn those days into something fun, and memorable.
Good luck, it's going to be fine!!! You will see.
