e-book Math Common Core

  I read about this math book in an Edweek article, Educators Craft Own Math E-Books for Common Core.  I'd love to hear what high school math teachers think of this one.  This is a link to the book.
Also the Illustrative Math Project from Arizona might be interesting for all grades.
