ーAnnouncementー The last shipment of the year will be on December 29th (for purchases made by December 28th). Shipping will resume on January 5th. Thank you for your understanding. ※※※※※※※※※※※※※※※※※※※※※※※※※※※※※※※※※※ This is a complete set of Noken Center's 5th-grade elementary school math textbooks, volumes 1-6. All answer keys are included. There are a few pages where the question numbers have been marked with red circles or crosses (see photos 2 and 3). Also, there were some places where the questions were written on in pencil, but these have all been erased (see photo 4). I have judged that neither of these issues will interfere with solving the problems, and have marked the condition as "no writing." The name on one of the separate answer key booklets has been blacked out with a marker. Also, there is some light soiling and scuffing on the cover. Please examine the photos and only proceed with the transaction if you are in agreement.
