孩子们好喜欢今天的数学课,这个喜欢对于孩子而言仅限于对学习方式的喜欢,即“描、拓、剪”的过程。今天这节课的重点在于认识这些平面图形并感受这些平面图形的特征。这些认知一定需要有效的实际操作作为支撑,尤其是在对“立体图形与平面图形的关系”的体会上,这是后期学习的重要基础。我问孩子们:“要想得到其中的一个面(图形),怎么办?”教室 Children like today’s math class, this love is limited to the children’s favorite way of learning, that is, “drawing, extension, cutting” process. The focus of this lesson today is to recognize these planar graphics and feel the features of these planar graphics. These perceptions must require effective hands-on support, especially in the context of stereoscopic graphics and plane graphics, which is an important foundation for later learning. I asked the children: “To get one of the faces (graphics), what to do? ” Classroom
