【教学目标】1.能在具体的情境中,探索确定位置的方法,说出某一物体的位置;能在方格纸上用“数对”的方法确定位置;同时感受用“数对”确定位置的优越性。2.让学生经历知识的产生过程,培养学生独立思考、合作交流、理解应用的能力,发展空间观念,增强学生运用所学知识解决实际问题的能力。3.通过对课程资源的开发,使学生感受到数学文化的魅力。
Teaching Objectives 1. In specific contexts, to explore ways to determine the location, say the location of an object; in the grid paper with “number of pairs ” method to determine the location; at the same time feel Number of pairs "to determine the location of superiority. 2. Let students experience the process of knowledge generation, training students to think independently, cooperation and exchange, understanding of the application of the ability to develop the concept of space, enhance students’ ability to use their knowledge to solve practical problems. Through the development of curriculum resources, make students feel the charm of mathematical culture.
