I went through all that. I was not disruptive in class. You’re misstating the case to say that someone was standing in front of the class endlessly repeating 2X2=4 . ... Oh, you didn’t mean it literally? Then what did you mean?
In my case I recall long division tests. A friend of mine and I had races to see who could complete them the quickest as we sat next to each other in fifth grade. I was doing them one by one, and he hit upon a mass production technique, where he drew all the division signs first, then filled in the dividends, then the divisors, then the quotients, aka answers ... it was all the same.
Of course, we were sitting in the front of the class, and one time the teacher decided to cut the quiz short, just to catch him out, since he hadn’t filled in any answers yet. Brutal.
“Then what did you mean?”
I meant they were boring the kid.
You said you didn’t get it, and I was spelling it out for you.
But now I get it: you didn’t really mean you didn’t get it. You were just trying to brag about what a friggin’ genius you were.
Think of it this way.
Many of us went through the same thing ‘in class’. Teachers constantly accused me of daydreaming (which I was), but I made top grades. I was daydreaming because I was bored. I was ‘ahead of the curve’ (even though most of the time I had the ‘best’ teachers). So likely, were you.
BUT..... at home, I was challenged constantly. I was provided with the tools (many times LITERALLY) to keep my mind (and hands) busy.
If you had parents (or only one parent) who had to work a job and keep up the house and pay the bills and they don’t have or get the time to spend ‘challenging’ you (or buying you educational toys and projects), what are you left to do with your very active mind ?
This leads to real frustration for the child, the parent(s) and the teachers. The child takes out that frustration where he(she) can, and that is often on the teacher and the other students.
