Is your copy of The Narrative of the Life of Frederick Douglass covered in too many post-it notes and notes? These timelines will help! They are good to use as reference sheets (e.g. has this happened yet? what other chapter talks about this?) as well as discussion sheets. I used them for discussion by making sure we covered major plot points, identified themes, and talked about character. I could quickly see if we were missing something. It also helped because I didn't have to scramble through my book looking for the page number. I could see right in front of me "this happened near the end of chapter --, after event --").
Each chapter (including appendix and the letters) is outlined with events and characters as well as annotated with questions and color-coded for themes about education and justice.
