What This Standard Means
What Students Need to Do
- Explain how U.S. aid to Greece and Turkey and the response in Korea aimed to stop communism from spreading. Judge what these actions achieved and what they did not.
What Mastery Looks Like
- Students can distinguish the 1947 aid policy from the 1950 military response under UN command. They can use South Korea's survival and Korea's continued division to support a judgment about success.
Common Misconceptions
- Students may think the aid policy required the United States to send troops to Korea. They may also think the war ended with Korean reunification or a peace treaty, rather than a 1953 armistice.
How to Assess It
- Exit ticket: On a blank Korea map, mark the 38th parallel. Then write two sentences explaining why the United States intervened in 1950 and one success and one limit of that response.

Ways to Teach It

Play a card sort matching aid to Greece, UN troops in Korea, and the 1953 armistice with their goals and outcomes.
Show a current map of North and South Korea; have students label the border and explain its link to the 1953 armistice.
