去年12月间,我曾随南京市小学教育参观团到上海市去参观。在那儿听了几节算术課,觉得几位教师对算术基本知識的教学都非常重視,值得我們学习。常見低級儿童一般会順口溜1、2、3……但对数的实际意义并不了解。上海市虹口区第三中心小学朱云寀老师說:儿童由于对数的概念不明确,所以有的搞不清数的次序,有的不懂得数与数之間的关系,有的不熟悉数的组成……。我平时重視培养儿童数的概念,在使儿童获得明确的数的概念的基础上,培养計算的熟練技巧。例如教儿童認識10,首先复习7、8、9三个数,先用图画讓儿童数,再写出数字,并比較7、8、9

Where I heard a few arithmetic classes, I think a few teachers on the basic knowledge of arithmetic teaching are very valued, it is worth learning. Common low children generally jingle 1,2,3 ... but the actual meaning of logarithms do not understand. Zhu Hongcun, a third primary school in Hongkou District, Shanghai, said: As the concept of logarithm of children is not clear, some do not know the order of the numbers. Some do not understand the relationship between the numbers and the numbers. Some are unfamiliar composition……. I usually attach importance to the concept of raising the number of children and develop the skill of calculation based on the concept of giving children a clear number. For example, to teach children to understand 10, first review of 7,8,9 three numbers, first let the number of children with pictures, then write the numbers, and compare 7,8,9
