Thank you for viewing. --- Z-Kai Workbook for Elementary School Students Expanding Thinking Skills Standard Edition: Discovery --- With Answer Key Perfect for long vacations. The quiz format allowed my child to work on it without getting bored. Since I've memorized the content, I'm offering it for someone else to use. Recommended age: Grades 3-5. During inspection, there is writing on one page in the main text (photo). Pencil markings were present on the first 4-5 pages, which I erased. Also, there are minor scratches on the front and back covers and corners from storage. I am a private seller, so I apologize if I missed anything. Please understand that returns and exchanges are not possible. As this item was used by a child and stored at home, please refrain from purchasing if you are looking for a perfect item. Please consider the photos and purchase accordingly. #JuniorHighSchoolEntranceExam #Z-Kai #Mathematics #ThinkingSkills #JapaneseLanguage
