This is a set of books for ABeka's 5th grade science:  Investigating God's World (5th edition).  It includes these books:  student book (#434221), teacher edition (#434345), a set of new,  unused quizzes and tests (#412309--still in shrinkwrap; these are unbound tests); quiz/test key (#434388) activities book (#412325--a new, unused book).  The student book is new and unused.  The teacher edition has a little wear on the cover and outside page edges; there are a couple of pages with notes and some highlighting; but the pages are in good condition.  The quiz/test key has a little wear on the cover.  The pages are in good condition.  

Thanks for your interest!  It is appreciated!!
