November 9, 2009, marked the twentieth anniversary of the opening of the Berlin Wall. The Wall, a symbol of the Cold War, separated the German people for 28 years (1961-1989), keeping those on the East side isolated. Although the construction and dismantling of the Berlin Wall is a significant part of history, the topic is little covered in the classroom. Textbooks generally include one sentence on the topic. And yet teaching about the Berlin Wall fits well with the pedagogical expectations outlined in the national standards created by the National Council for the Social Studies (NCSS). Of the 10 thematic strands outlined in these standards, both "culture" and "time, continuity, and change" illustrate the relevancy of the Berlin Wall to the social studies. The purpose of this article is to (1) provide educators with a classroom-tested simulation for teaching the Berlin Wall and (2) provide educators with a list of relevant resources. (Contains 3 notes.)
