数学最迷人的当属数学自身的魅力。但这种魅力,常常藏得很深,需要生动的教学来挖掘和演绎。在这一过程中,学生的视野变得开阔,思维变得灵动,素养得以孕育。因而,我们在教学每一个内容时,都要力求于平淡中见新奇,在平常处觅风景,不断用数学自身的美妙来吸引学生,打动学生,发展思维,培育素养。带着这样的理解来看《分数的初步认识》,会萌生出一些新的思考。在学生学习分数之前,接触到的数基本上都是整数。在整数世界里,数就是以“1”为单位的
The most fascinating mathematics is the charm of mathematics itself. However, this charm, often hidden deep, requires vivid teaching to dig and deduce. In this process, the student’s field of vision has become wider, his mind has become clever, and his accomplishments have been nurtured. Therefore, when we are teaching each and every content, we must try our best to find novelty in the dullness, find the scenery in the usual place, and constantly use the beauty of mathematics to attract students, impress students, develop their thinking and cultivate their accomplishments. With such an understanding of “preliminary understanding of scores,” there will be some new ideas emerging. Before students learn the scores, the numbers touched are basically integers. In the integer world, the number is in the “1” as a unit
