The Whole Teaching and Practice of Graphic and Geometric Concepts from the Structural Perspective:Take the Teaching of"Understanding Cuboids and Cubes"as an Example
In primary mathematics teaching,the content about graphics and geometry is an important part of study.This paper takes the teaching of"Understanding of Cuboid and Cube"as an example,tries to analyze the logic of the textbook and examines students'prior knowledge so as to reorganize the teaching process and cultivate the students'mathematical thinking based on their experience,which helps to let the students truly become the main part of the teaching process and enable them to grasp the characteristic concepts of graphics and geometry.
