教学内容:苏教版小学数学二年级下册第80—82页的例1、2题、“试一试”、“想想做做”第1~3题。教学目标:(1)使学生通过观察现实生活中物体的运动,认识物体平移和旋转运动的特点,能区分、判断这两种不同的运动方式,能正确判断简单图形在方格纸上平移的方向和距离。(2)使学生经历观察、模拟、判断等活动过程,体会物体的运动,感受平移和旋转的不同运动方式,培养观察、判断等思维能力。(3)使学生初步认识生活中的平移和旋转现象,感受数学与生 Teaching content: Sujiao primary school mathematics grade two volumes of the first 80 pages 80-82 questions, “try ”, “think do ” 1 ~ 3 questions. Teaching objectives: (1) to enable students to observe the movement of objects in real life, understanding the characteristics of object translation and rotation, can distinguish and determine the two different modes of movement, can correctly determine the simple graphics on the grid paper translation Direction and distance. (2) Make students experience the process of observation, simulation, judgment and other activities, experience the movement of objects, feel the different movement modes of translation and rotation, and cultivate the thinking ability of observation and judgment. (3) enable students to initially understand the phenomenon of translation and rotation in life, feel math and students
