I also have been frustrated when I haven't been able to find teaching materials for a book on eNotes. However, I encourage you to keep using this fantastic web site. Right now eNotes has only what are called quicknotes on this book, but eventually there may be a lesson plan and a study guide. Don't give up. The eNotes lesson plans are fantastic and provide many different activities. It will be worth your wait.
You've done the right thing by posting a question because there are many talented, well-read teachers on this site. Someone will be able to help you.
In the meantime, check out the eNotes Teaching Bank lesson plans (linked below). These are lesson plans for elementary literature classes. Here's how the web site describes them:
Designed to meet the needs of students in grade 6 and below, each lesson plan features day-by-day teaching plans, a student packet featuring study questions, vocabulary worksheets, end of book activities and discussion questions, as well as a teacher's answer key to the student packet.
