The month of September has become synonymous with commemorations of the September 11th attacks, which were the largest attacks on American soil since Pearl Harbor. This site from Scholastic offers over 30 lessons plans, activities, news stories, videos, and book lists "to help students comprehend the 9/11 attacks and their lasting impact on the United States and the world." For instance, the lesson plan, "Encountering History," is designed for 6th to 8th graders, but includes an extension for grades nine through 12. The directions for the lesson plan outline nine clearly articulated steps, such as activating students' prior knowledge about the September 11th attacks and leading students through a series of steps that culminate in conducting an interview with a person who witnessed the attacks, either in person or on television. There are links to news items and first person accounts, among many other resources.
