概念教学是学生掌握数学基础知识和基本技能的核心,正确理解数学概念是学好数学的基础。由于低年级学生还处于直观形象思维阶段,而数学概念一般具有严谨性和抽象性,这就造成了低年级学生对概念形成过程认识的困难。如何根据低年级学生的思维特点,突破概念教学中存在的问题,让低年级 Concept teaching is the core of students’ mastery of basic knowledge and basic skills of mathematics. Understanding correctly the concept of mathematics is the basis for learning mathematics. Because the junior students are still in the stage of visual thinking, mathematical concepts are generally rigorous and abstract, which makes the junior students’ understanding of the concept formation difficult. How to break through the existing problems in the concept teaching according to the thinking characteristics of the students in lower grades so that the lower grades
