【Series Overview】 "Shichida English for Life" is a series of English learning textbooks from the Shichida method. Each textbook is designed to make learning the basics of English fun. This set includes 8 books. Since one book was used every 3 months, this represents 2 years' worth of textbooks, along with CDs and a parent's guide. As shown in the photos, there is some writing in the books by the child. Also, in No. 17, the top part has gotten wet, and some of the text is faded or difficult to read on almost all pages. The CDs were stored in a dark place, but I haven't been able to check them all by playing them, so please refrain from purchasing if you are concerned about minor details. No individual sales, please. I believe my child used these when they were in their final year of kindergarten and first grade. The guide mentions children aged 3-4 and 5-6, so it might be suitable for children around that age. Personally, I think consistent listening from a young age is important! - Series Name: Shichida English for Life - Number of Textbooks: 8 total - Contents: English learning textbooks - Included: CDs, Parent's Guide Thank you for looking.
