@Jen.R Good for you taking into consideration the needs of each individual kid. I'm always a little skeptical when people think homeschooling, or public, or private school is the only good/rational/Christian/whatever option. Obviously different situations work for different parents and different kids at different phases of life and circumstances.
I'm a reluctant homeschooler too. We moved to rural Mexico, and there just aren't really any other viable options. I have been enjoying it, but I am also a little daunted by how much work it is to do a good job. Like you said on the other thread, you have to actually teach stuff, and have a plan and goals and not just bake some cookies and call it math.
I was a public school teacher, as was/is my dad, brother, sister-in-law, several aunts, and cousins. I don't have this big beef with the American education system (in functional school districts that are doing a good job, at least.) I have found the extreme reaction to things like common core standards alignment or even "textbooks" in the homeschool community to be a little mystifying. I know you can't replicate a classroom experience in your home, and there are definitely aspects that are better not imitated, but it's not like I'm aiming for the opposite of public school education.
I have a fourth grade boy who sounds a lot like your son. He spends all his screen time on Scratch (a site developed by MIT to teach young kids computer coding.) He asks a million questions I don't know how to answer, and I'm constantly telling him to watch a Kahn Academy video about X. It is really amazing what curious kids can teach themselves if you point them in a direction.
