“数学广角”是小学数学教学中一个非常重要的教学内容,它把重要的数学思想方法通过学生可以理解的、有趣的、容易接受的生活问题呈现出来,使学生通过观察、操作、实验、猜测、推理与交流等活动,初步感受数学思想方法的奇妙与作用,受到数学思维的训练,逐步形成有序地、严密地思考问题的意识。因此,通过在数学广角中的教学,使学生感受数学思想方法,提高他们的数学思维能力是重要的教学目标。在教学中我发现一部分学生对数学广角中的数学思想、
“Mathematics Wide Angle ” is a very important teaching content in primary school mathematics teaching. It presents important mathematical thinking methods through students’ understandable, interesting and easily accepted life problems so that students can observe, manipulate and experiment , Speculation, reasoning and communication activities, and initially feel the marvelous and role of mathematical thinking and methodologies, trained by mathematical thinking, and gradually formed a sense of thinking orderly and strictly. Therefore, it is an important teaching goal to make students feel mathematical thinking and methods and improve their mathematical thinking ability by teaching in the wide angle of mathematics. In teaching I found that some of the students in the mathematical wide-angle mathematical thinking,
