If you are currently a Teach For America corps member or an alumni like me (RGV '03), you can now download the digital version of my book for free via TFA's new Resource Exchange. All you have to do is log in on tfanet.org, click on "Resource Exchange" and search for "Ten Cheap Lessons" (make sure you include the quotation marks). This is one small way for me to give back to the organization that gave me the greatest, most challenging experience of my life.
If you don't fall into the above categories, you can find Ten Cheap Lessons: Easy, Engaging Ideas for Every Secondary Classroom at Amazon.com, Barnes & Noble and other fine retailers.
