由于小学低年级学生年龄小、好动、好奇心强,对新生事物的认识理解能力差,而直观感知的能力却很强,这就要求教师在数学教学过程中,充分利用低年级学生的感知特点,运用直观性原则提高教学质量,把数学基础知识的教学建立在直观基础上。因此,让学生在课堂上亲手动一动,胜过老师一遍又一遍地讲解。 Because of the small age of primary school students, active, curious, poor understanding of new things, but the ability to intuitive perception is very strong, which requires teachers in mathematics teaching process, make full use of the perception of lower grades students Characteristics, the use of intuitive principles to improve teaching quality, the basic knowledge of mathematics teaching based on intuition. Therefore, let the students in the classroom personally move better than the teacher to explain over and over again.
