There are going to be some awkward moments in the transition to the Common Core State Standards for mathematics, primarily because skills that frequently appeared before are now appearing a grade lower. Since students aren't getting any younger, it will be as if they're leapfrogging some standards, which is sure to cause some problems in the transition. There's hope that the path forward can still be smooth, even though it might take years to get there.
