数学概念是学生学习数学知识的基础,是判断和推理的起点,同时也是培养学生数学能力、发展学生思维的基础。所以,重视概念教学,优化概念教学,是我们每一位数学教师都必须认真深入思考的问题。但现在的数学课堂教学中不可避免地存在这样的一些问题。例如,当前的小学数学缺乏对概念教学的重视,小学数学教师缺乏对概念教学方法、教学模式的深入探究与思考,多采用一带而过的概念教学模式,学生也忽视对一些重要数学概念的深入认知 The concept of mathematics is the basis for students to learn mathematical knowledge, the starting point for judgment and reasoning, and is also the basis for developing students ’mathematical ability and developing students’ thinking. Therefore, the emphasis on conceptual teaching, optimizing the concept of teaching, is that every one of us mathematics teachers must seriously think in depth. However, there are some problems that inevitably exist in the current mathematics classroom teaching. For example, the current primary mathematics lacks emphasis on concept teaching. Primary mathematics teachers lack of in-depth exploration and thinking of concept teaching methods and teaching modes, and more adopt the concept of teaching mode. Students also neglect to deeply understand some important mathematical concepts Cognition
