近期,我们学校承办了一次市级教育教学研讨会。会上,我展示了一节凝聚我们智慧数学工作室集体智慧的“确定位置”(苏教版第十册)。本节课,我们对教材内容作了一些调整。课前交流以有趣的哥尼斯堡七桥问题中点线示图的方法,让学生感受把地点简化成点的简洁,既培养学习兴趣,也为课中把位置看成点作准备。具体教学则从横竖的生活经验入手,感受数轴的形成过程;在对位置由生活到数学的表达过程中,体会用有序数对表示平面中某个位置的必要,也体验由具体到抽象的数学简洁
Recently, our school contracted a municipal education and teaching seminar. At the meeting, I presented a section titled “Confirmation of Position” (the 10th edition of the Sujiao Edition) that unites the collective wisdom of our intelligent mathematics studios. This lesson, we made some adjustments to the teaching material. Pre-class communication with the mid-line diagram of the interesting Seven Bridge in Königsborg gives students a sense of simplifying the location to a point, nurturing interest in learning and preparation for location as a point in the class. Specific teaching starts from the experience of life and experiences, and experiences the process of the formation of several axes. In the process of expressing the position from life to mathematics, we can understand the necessity of using ordinal numbers to represent a certain position in the plane, and the mathematics from specific to abstract concise
