I am going to put a link for you here as soon as I’m back at my desk. Your self-description sounds EXACTLY like my son ( and Me, to a lesser degree…he is MUCH more highly intelligent than I am). After his kindergarten year I was terrified. I almost homeschooled him, and I would have if I wasn’t newly divorced and totally destitute. He had LOVED his first Kindergarten class ( because of his birthday we had to wait until he was six to enter him in public school. So his next step at preschool was the kindergarten class. They have a wonderful kindie teacher and are accredited but the school district won’t accept attendance there as a substitute for “real” kindergarten. What a joke! Alex learned absolutely NOTHING in his “real” kindie class except how to be bullied. And if ever a kid didn’t need 2 years of kindergarten, it was him. Anyway he went through first and second grade pretty unremarkably. One pretty good teacher, one less severe repeat of kindie ( funny they even LOOKED alike). He qualified for gifted services but not like he should have. He’s BRILLIANT. He was missing odd stuff in math, and had spelling errors I knew he knew correctly, etc.
At the same time he was writing a novel at home. Teaching me to play chess. Constantly inventing things or coming up with business plans for when he was a grown up. He had a massage business all figured out (LOL) that took into account supply and demand, which he had never heard of. He could look at a pile of coins and figure out in seconds how much was in it, to the penny. This was not a kid who couldn’t add 2+2.
He started doing weird equations on his math tests that weren’t what he was given and I realized he was doing algebra--his sister had just started it in 7th grade and he had been studying her book.
His answers were right, just not what was on the test.
So I googled til 3am one morning and found this article. Maybe it will help you understand better.
