I created three timelines. You will need to enlarge the font and make 'cards' out of each of the events and make four copies of each. I break my class into four groups and send them to different corners of the room. They then work together to place the cards in chronological order as both cause and effect practice as well as just a review of the chronology of WWI. The timelines include the causes of WWI, U.S. entry into the war, and an overview timeline of WWI. This product also includes a PPT answer key of the three timelines and embedded video clips to review the causes of war, how U.S. entered the war and a clip of Wilson's Presidency.
