C.,
Congrats on your decision to Home School. I am a home schooling Mom for 7 years now. If you want to personal message me any time, please feel free.
My first recommendation is to make sure what your state requires. In Texas we have the Texas Homeschool Coalition website to keep us updated on all things homeschool. After you determine what those requirements are, you are free to roam around the homeschool arena.
Please know to take it slow. You will make curriculum/scheduling choices that you will probably change your mind about. That's part of your learning curve and ALL homeschooling Moms have done it (and being completely honest continue to do so). I've done research, knew I was picking "the curriculum" and then it was not a good fit at all. Mainly you have to allow yourself those opportunities to learn. Learn how your children learn. I have one child who is an avid reader and the other not so much. I have one who is more auditory in learning. You will soon make aha moments when it clicks with you what works best for your family. Every family is different as well, so don't think there's something wrong with what you're doing if you need to make changes.
There are a lot of different "methods" in homeschooling. You can do as little or as much prep as you'd like. There are curriculums out there that you can buy the whole year for your student and be done. Some you can do completely online. The method I chose is the Charlotte Mason method of education. You can learn about it on the web. I have a 12 and 8 year old and it works well with us. A great book to look at is Cathy Duffy's Top 100 Picks. She gives a summary of the curriculums and also a great little tool to determine what kind of learners live at your house :) Depending on the size of your local library, it might be available there. If not, check half.com, ebay, or you could buy it new at Barnes & Noble or another book store. I use christianbook.com a lot for my curriculum. Right now they are running some really good sales getting back to the school routine.
I don't know if you have any homeschool conventions coming near you this late in the season, but that would be good to plan for next year if not. There you can see all kinds of curriculum all together. Each vendor has their own booth and can answer questions you have which is really nice too. It's also very nice to be in the company of other homeschoolers.
Lastly, I would encourage you to join a local homeschooling group. In Texas we have TONS of them. They usually meet once or twice a month, have an encouraging speaker, the kids have a lot of fun together and you can learn so much from others who are on this adventure as well.
Again, I know this is long and kind of vague. But if you want more specifics, encouragement or if there's ANYTHING I can help you with, please don't hesitate to message me. Blessings to you as you start this wonderful journey!
