In the 2016 revisions, while there are changes, we don’t anticipate them to to be a dramatic change. We feel like they’re providing more support, they’re providing better progression of content. And so, so the changes in 2016 should be pretty palatable to most teachers who take the time to go in and read the framework and really take a look at what those changes are. The standards and the framework were worked on simultaneously to give more cohesiveness between the two. Mathematics is a very coherent set of standards so we wanted things to connect across grade levels and across courses. So, the intent was to make sure that there was a very solid connection between the standards that were adopted and the curriculum framework which is a companion document to the standards that supports and gives greater clarity to the standards themselves.
