Fractions (and more)

Even if you don’t teach math to elementary school students, this set of short videos is an excellent introduction to the treatment of fractions in the Common Core State Standards.  It also gives a sense of what is meant by a “progression” in the mathematics standards.  Drafts of many more progressions, as well as a description of their origins and uses, can be found here.
