教学内容:北师大版小学《数学》二年级下册第七单元77—78页1分有多长。教学目标:建立1秒和1分的概念,知道1分=60秒;结合数一数、动一动、写一写、估一估等活动,发展学生估计时间的能力。在快乐的数学活动中,让学生反复体验1分钟的长短,感受时间的意义。编者语:愉快或欢娱令人感觉时间过得快,嫌时间太短;而在痛苦中煎熬则令人感觉时间太慢,泣光阴漫长。伟大的科学家爱因斯坦曾用这个人之常有的时间体验举例诠释“相对论”原理。看来,在快乐活
Teaching content: Beijing Normal University version of “Mathematics” second grade Volume seventh unit 77-78 page 1 minute how long. Teaching Objectives: Establish the concept of 1 second and 1 minute, knowing that 1 minute = 60 seconds; develop the ability of students to estimate the time by combining activities such as counting, moving, writing and estimating. In the happy mathematics activities, let students repeatedly experience the length of 1 minute, feel the meaning of time. Editor’s Words: Happy or joyous feeling of time flies, too short of time; suffering in the pain is feeling too slow, weeping a long time. The great scientist Albert Einstein used the usual time experience of this man as an example to explain the theory of relativity. It seems, happy life
