I have a question about the CCSS Flip books that are used by Kansas and ARizona. Can we assume these are vetted and approved by “the CC Powers?” I use them as a reference for training teachers, in Florida, and hope they are 🙂
“Vetted and approved” is a bit strong. I helped review the Arizona ones early on, but I don’t think there was time for a thorough review. So they are probably basically pretty good, but you should not attribute oracular authority to them. I don’t know about the Kansas ones.
