Graphical Mathematical Olympiad (Introduction)

How to develop children's mathematical thinking and improve children's learning efficiency? How to train children's mathematical application ability? How to lay the foundation for children's interdisciplinary learning through mathematics learning? These are the questions this book seeks to address. The purpose of this book is to train children's modeling thinking and number-shape thinking. This book introduces 12 drawing methods, including box diagrams, line segment diagrams, area diagrams, lists, inclusion and exclusion diagrams, mind maps, geometric figures, alien diagrams, butterfly diagrams, line diagrams, bar diagrams, and pie charts. Through practical learning, it helps children form a combination of number-shape thinking and modeling thinking, and improves children's mathematical application abilities and interdisciplinary learning abilities. This series of books is divided into two parts: lower grade and upper grade. It covers most of the application questions at the elementary school level, and uses visual methods to improve children's learning efficiency and prevent children from falling into the dilemma of rote memorization.
