A Civil War story of mine was recently recorded and broadcast by KVPR, an NPR affiliate. It is available as a free podcast and is fifty minutes in length. Here is the link:
"Lulu Garlic, Contraband" includes both Harriet Tubman and Abraham Lincoln as main characters. It details events from the last year of our Civil War. Should you wish to have your students listen to it, I've provided listening logs, directed reading assignments, reciprocal teaching assignments and three poster options. I think both the story and the assignments are suitable for 8th graders and up.
