This is a set of English conversation materials from Aeon for elementary school students, covering 6 years of study. Aeon Kids uses advanced learning, so it seems that the curriculum up to the 6th grade includes the learning content covered in junior high school. By studying only with Aeon, I was able to easily pass the Eiken (English Proficiency Test) Grade 4. All items have been used by a child, so the textbooks and workbooks have writing in them. The picture books, CDs, and DVDs are in good condition as they haven't been used much. Each grade level includes 2 textbooks, 2 workbooks, 7 picture books, 2 sets of CDs, and 2 DVDs, making a complete set. Only the PURPLE set is missing a CD and workbook 1. All other series are complete. We also welcome combined purchases with the set for pre-schoolers that we have listed separately. For those who understand that these are used items, how about using them for home study? Thank you. - Series Name: ENGLISH OCEAN ORANGE RED GREEN YELLOW BLUE PURPLE - Format: Textbook, Workbook, Storybook, CD, DVD - Target Age: Children, Elementary School Students - Quantity: Set - Language: English Thank you for viewing. #EarlyChildhoodEducation #English #EnglishConversation #EducationalMaterials #ElementarySchoolStudents #Aeon #Eiken
