1教学目标分析(1)知识与技能①通过具体丰富的模型或实物或图片体验、感受和认识以生活中的物体为原型的常见立体图形与平面图形,培养学生的识图能力;②能从具体物体中抽象出常见的立体图形,并能举出类似于这些立体图形的物体实例;③能从具体的较复杂的平面图形中找出熟悉的平面图形,重新认识平面图形。(2)数学思考①从周围熟悉的物体入手,经历对几何图形的直
1 Teaching Objectives Analysis (1) Knowledge and Skills (1) Through a variety of rich models or objects or pictures to experience, feel and recognize the living objects as the prototype of the common three-dimensional graphics and graphic graphics to develop students’ ability to identify; Abstract objects out of the common three-dimensional graphics, and can give examples of objects similar to these three-dimensional graphics; ③ From the more complex plane graphics to find a familiar plane graphics, re-understanding of the plane graphics. (2) Mathematical thinking ① Start with the familiar objects and experience the straightness of the geometry
