Chains is an emotional book about the life of a slave girl during the time of the Revolutionary War. The author weaves in real events and historical figures to create a story that is interesting and educational.
However that does mean that teachers need to be aware of what is fact and what is fiction. As you read this book with your students have them keep a list of things that are fact, fiction, and things that they are not sure of. This will give you opportunities to branch off into research topics.
Beware: this book is a bit heavy! There is a lot going on all at once. Make sure you have plenty of discussion and writing opportunities. It may be a good idea to do some drama with the scenes and discuss what the characters are thinking and feeling.
