什么是数形结合?我国数学家华罗庚有过非常精辟的诠释:形使数更直观,数使形更入微。形对于数、数对于形两方面的功能得到了高度的概括。那么,在小学数学教学中怎样渗透数形结合思想呢?下面就以“点图与数”一课为例,作简要介绍。“平方数”是沪教版《数学》二年级上册“数学广场”中的一个内容,意在通过本内容的教学,培养学生操作、观察、猜想、归纳等能力,初步感悟
What is a combination of several forms? Chinese mathematician Hua Luogeng had a very incisive interpretation: the shape of the number more intuitive, the number of the shape more in-depth. For the number of pairs, the shape of the two functions of the shape has been highly summarized. Then, in the elementary mathematics teaching how to infiltrate the idea of the number with the combination? Here to “point and number ” class as an example, for a brief introduction. “Square ” is Shanghai Education Edition “Mathematics” grade two volumes “Mathematics Plaza ” in a content, intended to teach through this content, training students ability to operate, observe, guess, summarize and other initial perception
