1、1/6 口算除法教学建议信息窗 1按时交货本信息窗呈现的是一个风筝加工车间的场景，一边是工人们正在加工风筝，一边是车间主任和厂长在谈话。图中“生产进度表上主要信息有：老鹰风筝还有60 只未完成，离交货还有 2 天时间；燕子风筝还有240 只未完成，离交货还有6 天时间；蝴蝶风筝还有320只未完成，离交货还有4 天时间；车间主任说：“保证按时交货。引导学生根据信息提出问题，借助“平均每天要做多少只老鹰风筝才能按时完成任务？引入对“整十数除以一位数口算除法的学习，借助“平均每天要做多少只燕子风筝才能按时完成任务？引入对“几百几十数除以一位数口算除法的学习。通过本信息窗的学习，学生应能够进一步体会除
2、法的意义，能正确口算整十数、几百几十数除以一位数的除法。教学时，教师可以采用与学生对话的方式，询问学生春天是否放过风筝，引发学生对风筝制作这一事件的关注。此时教师利用课件或者挂图出示该情境，引导学生观察情境图，以“从图中你了解到哪些信息启动教学，重点关注统计表中的文字信息包括统计表和对话中的内容。学生说出图中的信息后，教师再引导学生根据信息提出有价值的数学问题，并选择与本节教学有关的问题按顺序板书出来。如：“平均每天要做多少只老鹰风筝才能按时完成任务？等。“合作探索中共有1 个红点、1 个绿点问题。红点标示的问题是：“平均每天要做多少只老鹰风筝才能按时完成任务？引入“整十数除以一位数的口算除法
