1、认识旋转冀教版数学三年级上册第三单元1、结合实例，经历感受、认识旋转现象的过程。2、能辨认并从现实生活中找出旋转现象。3、对现实生活中的旋转现象有好奇心，激发学习数学的兴趣，增强学好数学的自信心。教学目标同学们，你们去过游乐园吗？谁能说一说自己都玩过哪些游乐项目？http:/ 旋转 。观察上图，说一说物体的运动是不是旋转？旋转：物体 绕着某一固定的点或轴转动 ，这种运动现象叫旋转。旋转的特征： 旋转都是 围绕这一个固定点或轴转动 ，且 物体的大小、形状没有发生变化 ，只是 自身方向发生变化 。说一说在生活中，你还看到过哪些旋转现象？练一练1.找一找下面事物中的平移或旋转现象。http:/ “
