I was homeschooled from 6th grade until I graduated high school.
I did the home program through a local private school as my mom wanted to augment my education. It was a religious school, but she wanted me to learn evolution and 'proper science'. There were other private schools that had home programs but this one had everything they did and was more affordable.
She did an excellent job. We did experiments, field trips, and sports.
In FL it is now illegal to exclude someone from a sport activity because they're home schooled. This law came about because of Tim Tebow of course, but it benefited all of us in homeschooling.
You'll have to be able to adjust to the child's learning style and go from there. Just make sure you keep it challenging enough to hold their attention, but not so intense that they give up.
Make and keep a schedule of how much time they have to spend on school work each day. No electronics (phones, games, et cetera.) allowed in the room during this time. If you don't then they'll use that time to play around, I've seen it happen a lot.
You have tons of options out there to use. You have computer programs for home schooling, books programs and more.
You can also, if you can find them. Get a group of other parents who homeschool together and do a weekly or communal home school day where all the kids are learning together. This works especially well for science class experiments. The only catch with this is that everyone has to agree on what to teach and the kids have to be on the same level generally. Someone who teaches creationism won't want their kids taught evolution, and vice versa.
Lastly, if you or your husband are a bit weak in a particular subject you can bring in a tutor once a week or so to keep the child up to par in that subject. My school offered free tutoring up to so many hours a week/ month to home school students, and it was a big help with math. They might have called it algebra 2, but I think it was really some kind of alien language, LOL.
All in all homeschooling is a great thing when done correctly, and is of a greater benefit than even public education as it's tailored to the child.
