Everyone remembers where they were and what they were doing on the morning of September 11, 2001. Everyone has a personal story from that day, and many of those personal stories took place in classrooms all across America. The reality of the terrorist attacks is difficult for adults to comprehend, yet it is the job of teachers to help students of all ages understand the events of September 11th and ponder what they mean for the future of our country. This task is especially difficult for teachers of young children. Primary grade children are developmentally unprepared for the abstract thinking, problem solving, and critical analysis necessary to make any sense of the tragedy and the events that followed. However, they did experience that day, just as adults did, and now experience the repercussions. Therefore, young children need opportunities to gain accurate information and discuss their feelings and reactions, and teachers must guide this learning. In this article, the author highlights children's literature on this topic that is appropriate for children in grades one through three. A summary of each book is provided, and literature extension activities that can assist teachers in incorporating this topic into their social studies classrooms are described. Furthermore, the author recommends strategies that teachers might use to help children deal with the anxiety and fear associated with terrorism. (Contains 19 endnotes.)
