My siblings, though, weren’t as self-contained as I was. My sister was more dependent on friends. One brother still has a chip on his shoulder-- he was always an introvert, but he blames some of his awkwardness on “not going to school and having friends like a normal person”.
We had a homeschool group that we’d use occasionally— they offered things like Prom and Graduation, which was nice to join together and do. Other homeschool groups in major urban areas might offer group sports, like basketball/soccer/baseball/volleyball. Some do things like Girl Scouts/Boy Scouts. Or you can do your own extras independent of the homeschool community, like horseback riding, or ice skating, or 4-H. And there’s always the local church Youth Group. There are a lot of options for getting out there and interacting.
It’s important to figure out what kind of educational theories/approaches you support, and which ones you don’t like, because there’s a ton of curricula out there, and it can be overwhelming if you don’t know the differences between this and that. For example— I homeschooled my kids for kindergarten, but DH wants them to meet the local kids, so they’re going to public school. But I still do a bit of after-schooling. So, take math-- there’s the Spiral Method and the Mastery Method. Saxon is one example of the Spiral Method. You do a little bit of fractions, a little bit of measurement, a little bit of time-telling, a little bit of word problems, a little bit of money problems-- and the topics repeat from grade to grade, so that by the time you hit 6th grade, you’re able to do all those things. Saxon Math is one example of the Spiral Method. Then there’s the Mastery Method, where you focus on one kind of math: single-digit addition, double-digit addition, single-digit subtraction, double-digit subtraction, multiplication, division, fractions, and throw in a smidge of time and money problems— and you get really good and doing that one thing before you move on to the next kind of math. Math-U-See is one example of the Mastery Method. I knew that my local school district taught Saxon Math, which is a good program, but it’s so ADD, it can be frustrating if you don’t get enough experience with a certain kind of math. I preferred the focus of Mastery. So I picked up some Math-U-See because I thought it was a better fit for how I thought Math ought to be taught.
