The Yalta and Potsdam Conferences during World War II were not only significant in their role in deciding the fates of Germany and Japan, but in planting the seeds of tension between the US and USSR. Students read summaries of these conferences and plot the relationship on a thermometer and using text to support their answers. "Quote sandwiches" are a technique used to help students appropriately integrate text into their writing. The first "bun" is a lead in with their own words, the "meat" is the quote, and the bottom "bun" explains how the quote answers the question. Students also read an article claiming that the atomic bomb was the root of the Cold War.
