Thank you for the article. I think for people who have children (like my youngest!) who are not interested in academics it is quite reassuring.
In general I am more in favour of child led academics than delayed academics - as in math (or whatever) is taught/explored when the child has a need or want for it. I think many (but not all!) children are not interested in heavy academics at a young age because they are hard-wired to play. that is their natural life stage. I would imagine helping out loving adults would be next, with academics being pretty far down on their list, lol.
Specific to the article (and the comments afterwards, they are blurring together in my mind) I think the article was spot on in several areas. One of reason so many people struggle with math is because their teachers (elementary more so than higher grades) are math phobic or do not have solid number sense themselves. The other thing it has highlighted for me is that children can gain a lot of knowledge in a short time if they are learning it at an appropriate time - like the sixth graders cited in the text.
This is an interesting read on teachers, attitude math and gender:
