I am using Whatever Happened to Penny Candy? as a guide for economics for my seventh grader this year. I also bought the A Bluestocking Guide to Economics along with it, and developed a year long study myself based on both books.
I have found the guide to be invaluable because it provides vocabulary words, thought questions, tests, ideas for further study and research, suggestions for essays, and additional essays for student reading (several are published within the study guide itself).
There is also a key in the back of the guide with answers for the instructor and material to help the teacher in the beginning of the book. It sets up a plan for reading and introductory material for the student before he or she even begins to read the actual text. There are also pages with suggestions for further reading and optional films to view that discuss the topics studied during the year.
I don't remember what I paid, but I think it has definitely made my life easier!:001_smile:
