Two Words of Caution Before Adopting a New Textbook


Looking for a new math textbook to align to common core?  If so, you are amongst thousands of school districts across the United States.  Just a few words of caution:

 
1.     Beware of textbooks that claim to align to the common core assessment.  As of today, the assessment has not been written so it would be impossible to align to the assessment.
2.     Beware of textbooks that claim they align to the content.  Math isn't just about what we teach, but more importantly the "how" we teach.  What are students expected to do with the mathematical knowledge.  The 8 mathematical practices are emphasized in the Common Core and are essential to a new textbook adoption.

If textbooks claim to align, we must go deeper than just taking their word.  Attached are two rubrics, one created by Mathematically Connected Communities (MC2) (http://mc2.nmsu.edu/), the other from NCTM.  I would definitely use these rubrics as starting points but would also recommend an in-depth understanding of the 8 Mathematically Practices encouraged and emphasized in the Common Core Standards for Mathematics.

Looking for an online textbook?  Below are some resources on open source textbooks: 
OER Commons gathers relevant materials about teaching, technology, research, and more, and encourages you to add links to materials, projects, or news related to the emerging field of Open Education.http://www.oercommons.org/courses/material_types/textbooks?gclid=CNjvlbPGx6oCFQYKKgodCEBP1A
California's Open Textbooks project, includes links to further resources: http://www.opensourcetext.org/index.htm
