This lot includes the current edition (2nd edition) of Abeka 7th grade Science Order & Design video manual, student textbook, answer key, quiz key, test key, and activity book key.  The textbook has a worn cover, but the inside is clean with no writing and complete.  The answer keys are in very good condition with no writing and little wear.  The video manual includes the lesson plans, reading quizzes, and progress reports.  These books would cost about $158 if bought new through Abeka.  We are a smoke-free and pet-free home.  Please check out my other lots of books as I will combine shipping costs to save you more.  Thanks for looking!
