When my high schooler come to me with math problems, the first thing I do is look at the failures and figure out what higher level step or concept is missing in the brain. Then I explain that, sometimes more than once with different approaches. Once the higher level thing clicks, I can just sit back and mostly watch.

Sometimes I'm not sure how a concept clicked, but something did and the right answers start coming out.
