美国华盛顿国立图书馆的墙壁上有三句话:“我听见了,但可能忘掉;我看见了,就可能记住;我做过了,便真正理解了。”低年级的学生以形象思维为主,靠直观感知获取知识。实践证明,动手操作对概念的形成、规律的发现、算理的理解、思维的发展等有着非常重要的作用。因此在我们数学课堂教学中,要重视动手操作活动,让学生在亲身体验中真正的理解和掌握数学知识。现就如何使动手操作活动变
There are three sentences on the walls of the Washington National Library in the United States: “I heard, but may forget, I see, I can remember; I did, I really understand. ” The lower grades students to image thinking Mainly rely on intuitive perception to gain knowledge. Practice has proved that hands-on operation has a very important role in the formation of concepts, the discovery of laws, the comprehension of arithmetic and the development of thinking. Therefore, in our mathematics classroom teaching, we must pay attention to hands-on activities, so that students in the hands-on experience to understand and master the real mathematical knowledge. Now on how to make hands-on activities change
