1、北师大版数学一年级上册动物乐园教学设计教学目标:1、通过数数、比较等活动,掌握比较多少的方法,借助情境,初步体会一一对应的思想。2、认识符号“”、“”、“”刚才我们比了比小熊和小鹿,让我们再来比一比其他的小动物吧。生:小兔和小鸟比。(让我们请上小兔和小鸟,变说边摆)师:它们谁多?谁少?你是怎样知道的?生:小白兔有 5 只,小鸟有 2 只,一只小白兔对应着一只小鸟,小白兔还剩下一些,小白兔比小鸟多,也就是5 比 2 多。我们用一个数学符号来表示就是:52。引导学生正确读:“52”读作 5 大于 2,表示 5 比 2 多。指导学生书写“”。开口对大数,尖头对小数。领学生齐读。一列排读,男生读,女生
2、读。【学生第一次接触大于号,感觉较难,教师引导学生积极动脑,大胆创想,把形和义结合起来,学生便于记忆,理解深刻,为学习小于号作下铺垫,同时也培养了学生的创新意识。】学习“”|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第 3 页,共 5 页文档编码:CF4Z1X4M7P2 HQ7K7P3X10V10 ZD2F3Y2J6D9文档编码:CF4Z1X4M7P2 HQ7K7P3X10V10 ZD2F3Y2J6D9文档编码:CF4Z1X4M7P2 HQ7K7P3X10V10 ZD2F3Y2J6D9文档编码:CF4Z1X4M7P2 HQ7K7P3X10V10
