冀教版数学二年级上册用2-6的乘法口诀求商

课前导入探究新知课堂小结课后作业表内除法（一）课堂练习5

课前导入看图说一说，鱼缸中有几种鱼？各有多少条？53（1）3种鱼一共有多少条？5×3＝15（条）或3×5＝15（条）答：3种鱼一共有15条。（2）把15条鱼平均放在3个鱼缸里，每个鱼缸放几条？1个鱼缸1个鱼缸1个鱼缸15÷3=5（条）（2）把15条鱼平均放在3个鱼缸里，每个鱼缸放几条？3×（）＝15（条）515÷3＝5（条）答：每个鱼缸放5条。（2）把15条鱼平均放在3个鱼缸里，每个鱼缸放几条？你还能提出用除法计算的数学问题吗？探究新知用乘法口诀求商的方法：除数是几，就想几的乘法口诀，除数和几相乘等于被除数，商就是几。算除法，要求商，乘法口诀来帮忙；乘法口诀前两数，一个除数一个商；口诀得数被除数，它们两个是等量。看图写出一个乘法算式和两个除法算式。÷＝÷＝×＝248842824课堂练习1.看图列式，用口诀计算。×＝36÷＝6÷＝3口诀：___________18181836三六十八2.（1）一共有(

)架飞机。124312＝（架）×（2）每3架飞机编成一组，可以编成(

)组。41234＝（组）÷（3）平均编成4组，每组有(

)架飞机。31243＝（架）÷3.用下面的卡片摆出三个除法算式。（每张卡片只能用一次）620185124263这节课你们都学会了哪些知识？课堂小结用乘法口诀求商:除以几就想和几有关的口诀。想:除数×商=被除数。1.从教材课后习题中选取；2.从课时练中选取。课后作业Unit6MoviesandTheatreAMovieoraPlay
