Anecdata: I didn't grasp any of algebra until 10th grade. From about 7th to 10th grade chemistry class, I was just winging it. Sure, 10x=30, I could get x. But any of the trig or the parabolas, not a chance. It wasn't until chemistry, when I actually had to use algebra to get the molarity, moles, grams, etc, that I was able to grasp it. I remember sitting in class after the bell let out, on my desk, just doing the molarity equations over and over. It was one of the largest smiles of my life. I finally got it.

So, math happens when it happens. Maybe, yeah, I was a little retarded from the rest of my peers in grasping this idea of algebra. But I did get it eventually, when I needed to use it, finally. Saying that math is 'hard' isn't the best way of going about it. Everyone is different and learns differently and at different times. Some may not be able to get 3rd year Calc until they are 30, some get it at 15.

I tapped out of formal math classes at number-theory at ~22. Diff-eqs, Lagrangians, General Relativity, all fine with me, but number theory was a whole different level of pedantry I was not about to dive into.

There was this study that found this kind of difference in application. People were given a logic problem phrased abstractly. Then other people were given the same logic problem, but phrased in terms of catching someone cheating at something. It was like people's IQ's suddenly greatly increased.

I also remember an anecdote about this father coaching his kid through the multiplication tables, which the kid didn't like and had trouble with. They were riding in the car quizzing the kid, who was not doing well, but then the kid asked to do the 7's, which he rattled off with aplomb. Turns out, the kid really liked football. (US football)

Nice ones!

I think application is important, but the diversity of what a child will care about is crazy large. You can't reach them all. My SO is a teacher (of chemistry, ironically) and some kids get the material and some just don't. It's not a lack of trying, it's just that they don't get it. As such, the frustration of the child comes out and makes things worse. Good family lives are very important throughout their lives and help, but some kids just aren't going to get certain subjects. We're all different people.

I think your first reference is to the Wason selection task:
