This kind of thing is what makes me suspicious when I hear education experts say that N is too young to teach kids X. It's fine for each jurisdiction to have its own ideas about when to introduce particular topics, but they probably have very little info about how well things would have worked at a different rate or in a different order.
This all goes n-tupley when we consider any individual kid in. In that case you should just see what the kid can do and wants to do for yourself and not bother with what teachers think they are unready for.
