The 2008 edition of the Open Court Reading program has its own name, Imagine It.
At least half of the units are the same though most have been moved around and sometimes switched to a different grade.
Not a lot of resources for this edition yet but what’s available you can find by visiting ImagineIt! Resources.com
There’s also more information about the new program available in the discussion board where a conversation is already taking place.
