So, this is my first blog post on our new discussion site. Many of you will be using the Common Core Algebra I curriculum this year that I wrote over many nights in the winter of 2013-2014. It is an imperfect text, and always will be. But, it can be made better through lesson study, comments, suggestions, and sharing. I believe that we can make a successful transition to the Common Core at the high school level with the input from practitioners around New York State and the country. I hope that you will join me in finding ways to build a better Common Core Algebra course.
