教学内容:人教版《义务教育课程标准实验教科书·数学》六年级上册第56~58页。教学目标:1.使学生在具体的情境中认识圆,知道圆的圆心、半径和直径的概念。2.通过观察、操作等活动,探究圆的特征,理解和掌握在同一个圆里半径和直径的相互关系,学会用圆规画圆。3.使学生进一步积累认识图形的学习经验,培养学生的观察能力、动手操作能力、抽象概括能力和合作交流能力,进一步发展学生的空间观念。
Teaching content: PEP “compulsory education curriculum standard experimental textbook · Mathematics” sixth grade on the first 56 ~ 58 pages. Teaching Objectives: 1. To enable students to understand the circle in a specific context, to know the circle's center, radius and diameter concepts. 2. Through the observation, operation and other activities, explore the characteristics of the circle, understand and grasp the same radius and diameter of the relationship between the circle, learn to use the compass to draw a circle. 3. To enable students to further accumulate understanding of graphic learning experience, develop students 'observation skills, hands-on ability, abstract abilities and ability to communicate, to further develop the students' space concept.
