This is totally true and there is so much more math that is accessible and fun to teens. The list in the blog post is great. We had fun doing some of this and I'm doing it now with my step kid who really likes math but also likes to be in class with his friend. I did encourage my own kid to take calculus in year 11 rather than the usual year 12 so that he would enjoy physics more. His physics teacher told me she changed a little so she would call out calculus applicability or offer some extra problems for him, not so much for him, she said (I think she didn't like him, actually) but because it was just more fun to have someone who understood the math. Interestingly he said he was the only calc student who actually wanted to be in the class (a dozen kids). He said the rest were there because their parents had been pushing them.
