This listing is for Math 6 (4th edition) (#525444).  The book has a good bit of wear on the cover, tears at the spine that were taped, very dog-earred corners.  The cover was coming loose on the inside so it was taped.  The first four pages (cover page and part of table of contents) are missing.  There is some water damage at the back of the book that affects the top of the pages a little, making them a little wrinkly.  The inside pages are in good condition; a couple of pages had a little pencil writing that was erased; the rest of the pages are not written on.  

Thanks for your interest!  It is appreciated!!
