The kids I am describing are somewhat lucky for not having "checked out" before progressing beyond fractions. But they're not extraordinary, they're just kids who have been taught competently and who have been motivated in one way or another to get that far. Kids are naturally curious and fighting against their curiosity can easily lead to losing their interest.
