Each chapter in each book has its own assignment.  Each assignment includes a vocabulary list of words used in that chapter.  We present the words, not in alphabetical order, but in the order, you will hear them.  Instead of providing definitions, we thought you might want the listener to look each word up, or put them in alphabetical order, or write their own definitions based on what they think the word might mean (from context) and then look it up and see how they did.
Each vocabulary list is followed up with questions related to the content of the chapter.  Our goal is to ask at least one question in each of the following categories:  History, Geography, Language, and Character.
After the questions, we provide suggestions for Activities the listener might do that will reinforce the information in that chapter.
