人教版小学三年级下册数学《口算除法》能力测试
《口算除法》能力测试一、口算下列各题.400÷2=500÷5=480÷4=620÷2=77÷7=420÷2=840÷4=26÷2=39÷3=80÷2=69÷3=88÷2=二、填空题.1.360除以3的商是()位数.2.120÷4=? 试想:()个10÷4=()个10=(). 3.3 000÷6=? 试想:3个()÷6=5个()=500.4.69÷3=? 先把6个()平均分成3份,每份是()个(),再把9个()平均分成3份,每份是()个(),最后把两次分得的结果合起来,得商是().三、在□里填上合适的数.(54-24)×□=120 40+□×3=100 (47+19)÷□=33 (18+12)×□=240 □×4÷6=12 (47+□)÷2=32四、先写算式,再写得数.五、解决问题.1.1千克黄豆可以生3千克豆芽,生60千克豆芽,一共需要多少千克黄豆?2.从320里减去一个整十数,得到的差再除以这个整十数,商是7,这个整十数是多少?(提示:解答此题可以倒过来算.从“得到的差再除以这个整十数,商是7”说明“得到的差”就是这个整十数的7倍.而“得到的差”恰好是“从320里减去一个整十数”后得到的,说明320比“得到的差”还多一个“整十数”.可以考虑320相当于这个整十数的几倍?) 3.青蛙可以活6年,比目鱼比青蛙多活54年,比目鱼的寿命是青蛙的多少倍?4.在除法算式459÷9中,被除数增加多少,商就增加2?被除数减少54,商就减少多少?部分参考答案一、200 100 120 310 11 210 210 13 13 40 23 44二、1.3 2.12 3 30 3.1 000 100 4.10 2 10 1 1 3 23三、4 20 2 8 18 17四、39÷3=13 180÷3=60 630÷3=210 360÷3=120 960÷3=320 150÷3=50 300÷3=100 240÷3=80五、1.20千克 2.320÷(7+1)=40 3.10 4.9×2=18,54÷9=6。

人教版三年级下册数学口算题
人教版三年级下册数学口算题一、口算题。
1. 20×30 =- 解析:计算时,先算2×3 = 6,然后看两个因数末尾一共有2个0,就在6后面添上2个0,所以结果是600。
2. 40×50 =- 解析:先算4×5 = 20,因数末尾共有2个0,就在20后面添2个0,结果是2000。
3. 12×30 =- 解析:把12拆分成10 + 2,先算10×30 = 300,再算2×30 = 60,最后300+60 = 360。
4. 23×20 =- 解析:先算23×2 = 46,因数20末尾有1个0,就在46后面添1个0,结果是460。
5. 30×15 =- 解析:先算3×15 = 45,因数30末尾有1个0,就在45后面添1个0,结果是450。
6. 11×40 =- 解析:先算11×4 = 44,因数40末尾有1个0,就在44后面添1个0,结果是440。
7. 13×30 =是390。
8. 50×12 =- 解析:先算5×12 = 60,因数50末尾有1个0,就在60后面添1个0,结果是600。
9. 40×14 =- 解析:先算4×14 = 56,因数40末尾有1个0,就在56后面添1个0,结果是560。
10. 22×30 =- 解析:先算22×3 = 66,因数30末尾有1个0,就在66后面添1个0,结果是660。
