26、相等,说明商 5 小了,应改成 6;第 2 个竖式,余数比除数大了,说明商 8 小了,应改为9;第 3 个竖式 50-56 不够减,说明商 7 大了,应改成 6。二、(1)20 3=6(个)?2(个)206=3(堆)?2(个)解析:本题主要考查的知识点是看图列式。图中一共有20 个樱桃,平均分成了3 堆,求每堆有几个,还剩几个,就是把20 平均分成3 份,列式为203;还可以看成一共有20 个樱桃,每 6 个放一堆,求可以放几堆,还 剩 几 个,就是求20 里面有几个6,列式为206。(2)266=4(束)?2(枝)264=6(枝)?2(枝)解析:本题主要考查的知识点是看图列式。图中一共有26
27、 枝花,每 6 枝扎一束,求可以扎几束,还剩几枝,就是求26 里面有几个6,列式为266;还可以看成一共有26 枝花,平均扎成了4 束,求每束有几枝,还剩几枝,就是把26 平均分成4 份,列式为26 4。三、1.B 解析:本题主要考查的知识点是有余数的除法。在有余数的除法中,余数必须比除数小,反之,除数一定比余数大,所以选择 B。2.A 解析:本题主要考查的知识点是有余数的除法。解决这类题的关键是计算有余数除法时,一定要牢 记余数必须比除数小。在 9中,余数必须比9 小,而在比9 小的数中,最大的是8,所以选择 A。3.C 解析:本题主要考查的知识点是有余数的除法。解决这类题的关键是计算有余数
28、除法计算时,一定要牢 记余数必须比除数小。在一道除数是 7 的有余数的除法 计算中,余数必 须比 7 小,我们还知道最小的余数是 1,那么 这道题的余数可能是1、2、3、4、5、6,所以选择 C。四、1.50 8=6(张)?2(元)答:50 元可以 买6张电 影 票,还剩 2 元。|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第 5 页，共 6 页文档编码:CN6H1R7T4W3 HQ6B5G2A5D8 ZM10F2N6R10Z1文档编码:CN6H1R7T4W3 HQ6B5G2A5D8 ZM10F2N6R10Z1文档编码:CN6H1R7T4W3 H

36、决 问题。从 题中可知,有 22 枝花,插在 3 个花瓶中,求平均每个花瓶插几枝,还剩几枝,也就是把22 平均分成 3 份,列式为22 3。计算时,先想口 诀:三(七)二十一,从而得到商7,余数是 1。3.25 3=8(件)?1(颗)答:这些纽扣最多可以 钉8 件衣服。解析:本题主要考查的知识点是余数的“去尾法”,解决这类题的关键是对余数的正确取舍。从题中可知,有 25颗纽扣,一件衣服 钉3颗,求这些纽扣最多可以 钉几件衣服,也就是求25 里面有几个3,列式为253。计算时,先想口 诀:三(八)二十四,从而得到8 件,还剩 1颗纽扣,余下的 1 颗纽扣不能钉一件衣服,所以最多可以 钉8 件衣服
37、。4.28 5=5(组)?3(个)答:超市门前的第28 个彩灯是 蓝色的。解析:本题主要考查的知识点是灵活运用有余数的除法解决问题,考查了分析能力和 计算能力。解决这类题的关键是对余数正确 应用。从题中可知,彩灯是按 红、黄、蓝、绿、紫排列的,也就是一 组有5 个彩灯,求第 28 个彩灯是什么 颜色的,也就是求28 里面有几个5,列式为285=5(组)?3(个),说明 28 个彩灯可以分成5组,还剩 3 个。这3个也是按 红、黄、蓝、绿、紫排列的,第 3 个是蓝色的,所以第 28 个彩灯是 蓝色的。|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第
