I organize my U.S. History course around a set of five themes and related essential questions. Conflict is one of the five important themes. You can read more about how I use these essential questions in my classroom here, and you can find a free Powerpoint to download on TeachersPayTeachers here.
Since I refer back to these questions over and over again throughout the course, it helps to keep them posted somewhere my students and I can refer back to them. I created this poster to both a) decorate my bulletin board and b) give my students a reference about some of the major questions related to the theme of Movement.
The file is a print-ready PDF intended for a regular 8.5" x 11" piece of paper. Download it, print it, and you're ready to go! Check my other listings for similar posters about Equality, Economics, Civics and Government, and Conflict.
