Included is background on the Zimmerman Telegram, one of 4 reasons for the U.S. entering World War One. There is an 11-slide PowerPoint showing relevant political cartoons from 1917, details on the declaration of war and more. The handout (4 per page, front and back) has the text of the Zimmerman Note in its entirety, as well as 5 text-dependent questions to be printed on the back). My class did this is about 1 full class period. Enjoy!
