《万以内数的加减法》口算专项练习2
最新人教版三年级数学上册第四单元《万以内的加法和减法(二)》练习题
第四单元万以内的加法和减法(二)【例1】678+541的和是()位数。
A.三B.四C.五解析:本题考查的知识点是利用分类讨论思想解答三位数加三位数的和可能是三位数,也可能是四位数。
本题百位上的数的和满十时,需要进一,就是四位数,解答此题的关键是要明白两个数相加后百位是否满十。
解答: B【例2】小亮家、小红家和图书馆在同一条路上,小亮家到小红家有多远?解析:本题考查的知识点是利用分类讨论思想解决简单的实际问题。
解答此题的关键是要理解“在同一条路上”他们两家和图书馆的位置有两种情况:一是小亮家和小红家都在学校的同一侧,根据减法的意义可得:428-123=305米;二是小亮家和小红家在学校两侧,根据加法的意义可得:428+123=551米。
解答:428-123=305(米)或428+123=551(米)答:两家的距离可能是551米或305米。
【例3】小粗心,太大意,计算减法看错题,被减数个位的8抄成3,减数十位上的2抄成5,这样算出的差是305。
你知道正确得数是几吗?解析:本题考查的知识点是用“错中求解”的方法解答抄错数问题。
解答时,先明确的是被减数减少了8-3=5,减数增加了50-20=30,差少了30+5=35,正确的差:305+35=340。
解答:8-3=5 50-20=30 30+5=35 305+35=340答:正确的得数是340。
【例4】减法数字谜。
(1)(2)解析:本题考查的知识点是三位数的加减法数字谜。
解答时,一般先从个位开始分析,然后利用分析、分类、讨论等方法十位和百位上的数最后得出答案。
(1)个位上的3减去一个数,结果是6,说明需要借位,这样得出13-()=6,因此个位里填13-6=7;然后看十位上的数:()-7=5(注意这里有一个借位数1),想:()-7=5,这里()里应是12,再加上借走的1,所以这里应填3;最后看百位上的数,9-()=1(注意这里的9应是8),所以括号里填9-1-1=7。

人教版数学三年级上册《第四单元 万以内的加法和减法(二)》练习题含答案
第四单元万以内的加法和减法(二)【例1】678+541的和是()位数。
A.三B.四C.五解析:本题考查的知识点是利用分类讨论思想解答三位数加三位数的和可能是三位数,也可能是四位数。
本题百位上的数的和满十时,需要进一,就是四位数,解答此题的关键是要明白两个数相加后百位是否满十。
解答: B【例2】小亮家、小红家和图书馆在同一条路上,小亮家到小红家有多远?解析:本题考查的知识点是利用分类讨论思想解决简单的实际问题。
解答此题的关键是要理解“在同一条路上”他们两家和图书馆的位置有两种情况:一是小亮家和小红家都在学校的同一侧,根据减法的意义可得:428-123=305米;二是小亮家和小红家在学校两侧,根据加法的意义可得:428+123=551米。
解答:428-123=305(米)或428+123=551(米)答:两家的距离可能是551米或305米。
【例3】小粗心,太大意,计算减法看错题,被减数个位的8抄成3,减数十位上的2抄成5,这样算出的差是305。
你知道正确得数是几吗?解析:本题考查的知识点是用“错中求解”的方法解答抄错数问题。
解答时,先明确的是被减数减少了8-3=5,减数增加了50-20=30,差少了30+5=35,正确的差:305+35=340。
解答:8-3=5 50-20=30 30+5=35 305+35=340答:正确的得数是340。
【例4】减法数字谜。
(1)(2)解析:本题考查的知识点是三位数的加减法数字谜。
解答时,一般先从个位开始分析,然后利用分析、分类、讨论等方法十位和百位上的数最后得出答案。
(1)个位上的3减去一个数,结果是6,说明需要借位,这样得出13-()=6,因此个位里填13-6=7;然后看十位上的数:()-7=5(注意这里有一个借位数1),想:()-7=5,这里()里应是12,再加上借走的1,所以这里应填3;最后看百位上的数,9-()=1(注意这里的9应是8),所以括号里填9-1-1=7。

人教版三年级数学上册《万以内的加法和减法(二)》同步试题
《万以内的加法和减法(二)》同步试题一、填空1.在□里填上合适的数。
考查目的:这是一组基本的三位数加减三位的笔算练习,让学生巩固“从个位算起”“满十进一”“不够减退一当十”的计算法则,形成计算技能。
答案:解析:第(1)题是不进位加法,第⑵题是进位加法,第⑶题是不退位减法,第⑷题是退位减法。
2.算出每张卡片上的两个数的和与差。
考查目的:熟练掌握进位加法和连续退位减法的计算。
答案:和775 和731 和821差539 差219 差183解析:本题根据整数加法与减法的运算法则计算出每张卡片上的两个数的和与差即可。
3.填表。
总数量卖出还剩37989576157174265考查目的:让学生进一步巩固所学知识,同时体会计算在实际生活中的价值。
答案:290,419,439。
解析:根据加减法的意义和总量与部分量之间的数量关系,分别列出“379-89”“576-157”“174+265”。
4.用6、4、8组成的三位数中,最大的数比最小的数大()。
考查目的:本题需要学生利用简单的排列组合先分别找到最大三位数和最小三位数,再利用减法法则正确进行计算。
答案:864-468=396解析:组成最小的数则是把三个数从小到大排列,即468;最大的数从大到小排列,是864,二者相减即可,解决本题的关键是找出最大的数和最小的数。
5.把下列算式按得数的大小,从大到小排列。
603-325 900-409 56+731 498+504()>()>()>()考查目的:培养学生用估算解决问题的意识和能力。
答案:498+504>56+731>900-409>603-325解析:603-325≈300,900-409 ≈500,56+731≈800,498+504≈1000二、选择1.下面哪两个数相加得1000?()A、536和361B、649和341C、792和208考查目的:培养学生灵活选择解题策略解决问题的意识和能力。
答案:C解析:根据A的个位6加1等于7,B的十位上4加4等于8,排除A和B的可能性,然后笔算选择C。
