The United States Memorial Holocaust Memorial Museum has developed many excellent online activities accessible to English Language Learners.

I’d like to highlight their site Genocide in the Congo, which, among other elements, has a journal written by Angelina Jolie.  She also provides audio of the text.

I’ve placed the link on my World History page in the middle of the Toward The Twenty-First Century section (the title is a little out-dated because the book we use, even though it’s excellent for English Language Learners, is a little old).
