"Cultivate "Arithmetic Skills" by the End of Third Grade: Lessons from a Head Teacher Whose Cram School Has Produced Math Olympiad Winners for 10 Consecutive Years" by Toru Tanabe Price: ¥1600 #ToruTanabe #Toru_Tanabe #Book #Society/Education/Learning I read it once with a book cover on. There are no major tears or folds, but the cover is slightly warped. Otherwise, it's in good condition. For those who understand that this is a used book, thank you.
