I homeschool 2 of my kids. 4th and 6th grade (10yrs old and 12 yrs old)
As for curriculum, honestly, what works for one kids will not work for another. So don't expect to use the same for all of them. Kids learn differently. My dd is great at remembering what she reads, so she can read and read and she'll learn, my ds does not, he has to see it, hear it, do it. He's a kinesthetic learner, vs auditory.
I am a curriculum addict, I've tried sooo many. I'm what is called an ecletic homeschooler. I use different sources to piece together what I need.
My goal for my kids is to teach them to be autodidacts..self teaching. I want them to learn how to teach themselves. We try to let them lead with what they want to learn. We do math and LA everyday, we do science, vs just reading about it. I have some great curriculum for that, it's so important that they do science and not just read about it..they need to experience it. For history, none of of enjoy it per se, so we do a lot of documentaries, it brings history alive. For geography we are using the Amazing Race! They are learning cool things about each country that they visit.
For a starting off point, Time4learning is ok. My kids got bored with it by 4th grade as it's somewhat "kiddish" and can be annoying. I find it doesn't dive deep into much, but it is an excellent starting point while you figure out what you are doing.
The great thing about homeschooling is it can anything you want it to be. It doesn't have to be school at home if you don't like that. Also, you don't spend near as much time as you do in regular school because there isn't as many students and you can go at the speed of your childs learning velocity. One will be great at math and suck at LA, that's ok, they can go ahead in math a the speed they need and slow down with LA until they understand. That is why I love it. My kids are totally different.
mobymax.com is a great free LA and math program that a lot of school use even.
I have a pinterest page that has TONS of boards with hs stuff..

The first thing you have to do before buying any curriculum is figure out what type of learners your kids are.
There are many free ways to do it...
here's one that you can secularize if you don't want religion added in there (like bible work etc)

My favorite resource is http://www.homeschoolbuyersco-op.org/
Used curriculum... homeschoolclassifieds.com
You can also find many homeschool books/curriculum at your library!
You need to find out what your laws are..

Get in touch with other hs'ers in your area, they will know the laws best.
Also, you'll need to figure out what type of hs'er you are, are you a stonch Christian? Secular? Christian but believe in evolution? These are important because many curriculums out there are very heavily Christian (like New Earth Christian). I am a secular hs'er, meaning I don't do any Christian curriculum. Religion in our house is only for historical purposes and it's for all religions, not just Christianity.
It looks at though Nevada is a great/easy state to homeschool, this is good for you, makes it much easier when you don't have to jump through loops.
Ignore all the socialization "issues" people have, they don't socialize in a brick and mortar school either. It's a bunch of crap unless you plan on being a hermit. My kids do a trampoline day (a giant place of a just trampolines), they take archery once a week, play basketball and soccer during those seasons, we are about to take some computer classes at a local gaming and computer repair lounge, also about to take sewing classes, all of this with other homeschoolers. And in the group I started we are about to do some science and engineering classes at my house..loosly formed. Just do tons of experiments and such! We are going to be sending a weather balloon up with a gps and cameras early this summer! Learning about flight patterns, wind patterns, gps, satellites, navigation etc...
I suggest you search facebook for homeschool pages. If you go into my profile, you will see a ton under my likes. (be sure to search "Las Vegas Homeschoolers" or something and you can find local groups. If you want secular, but sure to put that in your search)
If you have any questions at all, I'll be happy to help! I've helped a few people switch from public to homeschool like I did.
Be prepared to doubt yourself..be prepared to think you are screwing your kids up, be prepared to think you are supermom and the best teacher ever! It's totally worth it for us!
