A People’s History Of The United States by Howard Zinn is a good source for U.S. History lessons, and is particularly useful, I think, in teaching English Language Learners. Even though the language is probably not accessible to ELL’s, I’ve been able to adapt information (especially related to the role of immigrants) from the book for my classes.
The entire book is now available for free online, so now, with copy and paste, it’s even more useful for lessons.
Thanks to the US History Teachers Blog for the tip.
I’ll also be placing the link on my Teacher’s Page.
