What This Standard Means
What Students Need to Do
- Students explain why U.S. neutrality ended in 1917, using evidence about German submarine attacks and the Zimmermann Telegram. They trace changes at home, including the draft, war work, and limits on speech.
What Mastery Looks Like
- A student can put key events in order and explain why the United States entered the war in 1917 rather than 1915. They can connect the war to the draft and describe how it changed work or civil liberties at home.
Common Misconceptions
- Students may think the sinking of the Lusitania led to an immediate declaration of war, though it happened two years earlier. They may mistake the Zimmermann Telegram for a completed alliance with Mexico. Some assume wartime jobs brought equal rights for women and Black Americans.
How to Assess It
- Exit ticket: Name two specific reasons the United States entered the war in 1917. Then explain one way the draft or a wartime speech law changed life at home.
Lesson moves
Ways to Teach It
Give groups dated cards for the Lusitania sinking, renewed submarine attacks, the Zimmermann Telegram, and the draft; have them build a wall timeline.
Display the 1917 'I Want You' poster and have students write one reason it gives for enlisting and one cause of war it leaves out.
Run a card sort: students place submarine attacks and the telegram under causes, then place the draft, factory work, and speech laws under effects.
Print a current Selective Service registration page and a 1917 draft notice; have students circle who had to register in each.
