• 14、Thank you very much for taking me with you on that splendid outing to London. It was the first time that I had seen the Tower or any of the other famous sights. If I'd gone alone, I couldn't have seen nearly as much, because I wouldn't have known my way about.
总结: 在计算一位数除以几百几十数时,可以将几百 几十数看作几个十的数除以一位数,把它转化 为表内除法。
学习几十几除以一位数
把66张彩色手工纸平均分给3人,每人得到多少张? 66÷3
60÷3=20 6÷3=2 20+2=22 66÷3=22
三、巩固练习
15÷5= 3 150÷5= 30
80÷2= 40 88÷2= 44
280÷7= 40 2800÷7= 400
46÷2= 23 64÷2= 32
=8 =80 =800
=6 =60 =600
=3 =30 =300
100
60
80
40
50
30
20×2= 40 400×2= 800 12×3= 36 24×2= 48 40÷2= 20 800÷2= 400 36÷3= 12 48÷2= 24
四、课堂小结 通过本节课的学习,你有什么收获?和同伴交流。
