数概念教学是小学数学教学的重要组成部分,是学生学习数学和运用数学解决数学问题的基础。新课程改革根据小学生已有的知识经验、心理发展规律,对数概念教学内容的编排作了较大的调整,呈现由简到难、螺旋上升的编排体系,重视数感的培养。下面笔者结合教研实践,谈谈自己对数概念教学的一些思考。一、数概念的引入《数学课程标准》指出:“学生的数学学习内容应当是现实的、有意义的、富有挑战性的,数学教学活动必须建立在 Number concept teaching is an important part of elementary mathematics teaching, which is the basis for students to learn mathematics and solve math problems by using mathematics. The new curriculum reform made great adjustments to the arrangement of the concept of logarithmic concepts based on the existing knowledge and experience of the pupils and the rules of psychological development, presenting a system of arrangement from simple to hard and spiraling up to the importance of cultivating the sense of number. The following combination of teaching and research practice, talk about their own concept of logarithm of some thinking. I. INTRODUCTION OF NUMBER CONCEPTS The Mathematics Curriculum Standard states: ”Students’ mathematical learning content should be realistic, meaningful and challenging, and mathematics teaching activities must be based on
