The "new" Common Core edition of the Algebra 2 Book

 Note that the authors are the same. 

Chapter 1 is the "old" Chapter 5.

In case you are wondering, Chapter 2 is the old Chapter 6.  

What is now Chapter 3 used to be Chapter 7 and what is now Chapter 4 used to be Chapter 8.

Perhaps future students will be prepared for this, but this year's students - new to Common Core - are not.
