A series designed to cultivate the power of thinking, the foundation of all learning. Based on insights from the American education system and the Kumon method, this unique Kumon workbook focuses on developing thinking skills in four basic areas: "Perceiving Shapes," "Distinguishing," "Reasoning," and "Expressing." "Distinguishing Skills" helps children develop "discrimination skills" through fun activities such as identifying poses, finding differences between similar pictures, and searching for objects within pictures. 【3 Key Features of the "Kumon Thinking Workbook" Series】 (1) The "small step" method, where the content gradually becomes more challenging, allows children to progress without difficulty. They can experience the "joy of accomplishment" after completing each page, fostering their confidence and motivation. (2) By focusing on one area in each book, children can feel their skills developing. They can approach one area with various types of problems and learn without getting bored until the end. (3) This workbook is designed for parents and children to work together, with prompts and questions. It also includes plenty of advice for parents on how to interact with their children. *Includes "Well Done!" stickers and a "Great Job!" certificate. *Each page is perforated so that it can be easily detached for learning. ※This book is a revised edition of "Thinking Skills: Discrimination" published by our company in 2018, with a new title, cover design, and illustrations, and some revised problem content.
