"Turning Weaknesses into Strengths: Fraction Calculations for Grades 3-6" Edited by Suken Shuppan Editorial Department Price: ¥900 #SukenShuppanEditorialDepartment #Books #Society/Education/Learning I used to make copies of it, so there are no markings. However, it was knocked over on the bookshelf, so it's a bit warped. I don't think it will affect its use, but I apologize to those who are concerned. For those who don't mind, thank you very much.
