12 books on skill development, equivalent to one year of a first grader's curriculum. (April 2024 - March 2025) Shichida Elementary School Course The content includes numbers, haiku, four-character idioms, social studies, science, countries around the world, and more, providing a variety of knowledge. I've only flipped through them, but they have been used once, so some books may have shelf wear or minor soiling from storage. Please refrain from purchasing if you are concerned about minor imperfections. *The audio CD for skill development is not included, as it is available via app subscription. #Shichida #SkillDevelopment #ShichidaChildAcademy #Ikuwel #ShichidaMethod #ShichidaEducation #ShichidaEducationalInstitute #EarlyChildhoodEducation #SHICHIDA
