Oh, and while I think a verbal kid can have an easier time than a mathy kid, since even easy books still contain stories and let a child imagine, I don't think keeping a reader at a lower level of books than s/he can read is going to work for long either. If the child is denied access to the "big kid books" in the library (as mine was), it does "starve" the child, as bianca so aptly put it.

Again, I think there's got to at least be some differentation, and that's the worst option available as far as I'm concerned.
