① 小学四年级下册数学四则运算练习题
今天离开学还有倒数半个月,天气特别晴朗,妈妈说要带我去买菜,我高兴的从被窝里跳起来,赶紧穿好衣服和妈妈一起来到了菜场,哇!菜市场真热闹,人山人海,叫卖声、欢笑声,我看见了又圆又红的西红柿像苹果,看见了又细又长的豆芽,我还看见了紫色的茄子像弯弯的月亮,又像可爱的小船,还有许多绿叶的菜,生菜、青菜、白菜等等。 听妈妈说:“今天,我的大伯、二伯、姑姑全家都要来我家来,为我即将开学接个好彩头来庆祝庆祝。”于是我和妈妈买了许多菜,如:买了二斤西红柿,每斤二元;冬瓜买了三斤,每斤一元;长豆角买了三斤,每斤二元;黄豆芽买了二斤,每斤一元。这时妈妈给我提出个问题,鑫鑫你用所学的数学知识把今天买菜需要花多少钱算一算。我笑了笑告诉妈妈,一共支出十五元。其算式如下: (2×2)+(3×1)+(3×2)+(2×1)=15(元) 妈妈满脸笑容的对我说:“嗯,回答正确。”%D%A补充:%D%A我特地借我妹的日记书抄来的(她也4年级) 借鉴借鉴咯!%D%A
② 四年级四则运算题有点难度好
四年级四则运算题:
一、填空
