圆是我们日常生活中常常见到的平面图形。孩子从小就喜欢玩一些与圆有关的玩具,如球、圆柱型的积木、圆盘型的小轮子等等。上幼儿园以后,老师教幼儿认识的第一个几何图形就是圆。那么怎样把幼儿平时接触的与圆有关的物品、玩具从圆的角度概括起来,引导幼儿正确认识什么是圆呢,这个问题值得探讨。在引导幼儿认知事物时,既要注意到讲解适合动儿的理解能力,提高他们认知事物的积极性和兴趣,又要注意到讲解的科学性。认识圆的过程也应是这样。在幼儿园认识圆的教学中,老师往往是指着一些与圆形相似的物体说:“圆是圆圆的,没有边、没有角的。”
The circle is a graphic that we often see in our daily lives. Childhood like to play with some of the circle-related toys, such as balls, cylindrical blocks, disc-shaped small wheels and so on. After kindergarten, the first geometric figure the teacher taught her to recognize is a circle. So how to contact with children usually round with the round items, toys summarized from a round angle, and guide children to correctly understand what is a round it, the issue worth exploring. In guiding children’s cognitive things, we should not only pay attention to explaining the appropriate understanding of moving children’s ability to enhance their awareness of the enthusiasm and interest in things, but also to note the scientific nature of the explanation. The same should be true of the circle. In the teaching of kindergarten to know the circle, the teacher often refers to something similar to the circle and said: “The circle is round, there is no edge, no corner.”
