数学思想是数学的灵魂。日本著名数学家米山国藏曾经说过:在学校学的数学知识,毕业后若没什么机会去用,一两年后,很快就忘掉了。然而,不管他们从事什么工作,唯有深深铭刻在心中的数学的精神、数学的思想方法、研究方法、推理方法和看问题的着眼点等,却随时随地发生作用,使他们终生受益。这说明数学思想方法对人的发展起奠基作用。课程标准明确提出:“要使学生理解和掌握基本的数学知识与技能、数学思想和方法,获得基本的数学活动经 Mathematical thinking is the soul of mathematics. The well-known Japanese mathematician Miyamoto Kanko once said that in mathematics at school, there is no chance to use it after graduation, and one or two years later, it is quickly forgotten. However, no matter what their work, there is only the profoundly inscribed mathematical spirit, mathematical thinking, research methods, reasoning methods and the focus of the problem, etc., all the time to make their life-long benefit. This shows that mathematical thinking and methods play a foundation role in human development. Curriculum standards clearly put forward: ”To enable students to understand and master the basic mathematical knowledge and skills, mathematical ideas and methods, access to basic mathematical activities
