三年级数学下册口算练习题口算是数学学习中非常重要的一部分，它可以帮助孩子培养快速计算能力、提高思维敏捷度和注意力。

下面是一些适合三年级学生的口算练习题：1. 加法练习：- 5 + 3 =- 9 + 6 =- 4 + 7 =- 8 + 2 =- 6 + 1 =- 3 + 9 =- 2 + 8 =- 7 + 5 =- 1 + 4 =- 5 + 7 =2. 减法练习：- 9 - 3 =- 6 - 2 =- 8 - 5 =- 7 - 1 =- 4 - 2 =- 5 - 4 =- 3 - 1 =- 2 - 1 =- 7 - 6 =- 9 - 7 =第1页/共3页锲而不舍，金石可镂。

3. 加减混合练习：- 6 + 2 - 1 =- 5 - 3 + 2 =- 4 + 6 - 2 =- 3 - 1 + 5 =- 9 + 4 - 2 =- 7 - 2 + 3 =- 2 + 4 - 3 =- 8 - 3 + 7 =- 6 + 1 - 4 =- 3 - 2 + 6 =4. 乘法练习（小数乘整数）：- 0.5 × 2 =- 0.3 × 4 =- 0.4 × 5 =- 0.6 × 3 =- 0.2 × 6 =- 0.7 × 1 =- 0.1 × 9 =- 0.8 × 7 =- 0.9 × 8 =- 0.5 × 6 =5. 除法练习（整除，无余数）：- 10 ÷ 2 =- 12 ÷ 4 =- 20 ÷ 5 =- 18 ÷ 3 =千里之行，始于足下。

- 16 ÷ 8 =- 21 ÷ 7 =- 25 ÷ 5 =- 27 ÷ 9 =- 14 ÷ 2 =- 15 ÷ 5 =通过不断地练习口算题，孩子可以逐渐提高计算速度和准确性，同时也可以提高对数字的理解和运算能力。

小学数学三年级下册口算天天练小学数学三年级下册口算（天天练）口算是小学数学学习的重要内容，是小学生数学作业和数学考试的重要组成部分。

下面是小编整理的小学数学三年级下册口算（天天练），欢迎大家借鉴与参考，希望对大家有所帮助。

一、口算：口算题很简单，关键看做题时，不要看错运算符号，记得进位退位，记得0的`个数别多别少(1)36÷3= 180÷6= 76÷1= 720÷9= 320÷8= 84÷4=60×3= 490÷7= 56÷2= 700÷7= 930÷3= 240÷8= 21×3= 0÷5= 800÷4= 240÷2= 100×0= 100+0=(2)12×40= 60×11= 52-19= 280÷7= 32×30= 200×4=25×40= 12+20= 41×2= 69÷3= 13×20= 0×50=50×90= 50×20= 540÷6= 16×5= 50×80= 125×8= (3) 600÷3= 300÷6= 40×20= 320÷8= 60×30= 404÷4=82÷2= 360÷3= 660÷6= 22×40= 15×60= 61×10=963÷3= 75×2= 398×0= 0÷807= 420÷3= 650×2=(4) 30×23= 10×25= 33-18= 50×90= 40×20= 45+27=480÷6= 41×20= 94-57= 600÷6= 30×90= 20+34=0÷5= 200÷4= 420÷2= 57+33= 780+20= 900÷9=(5) 200×3= 24×2= 20×40= 63÷3= 280÷7= 800÷4=23×30= 25×4= 21×4= 43+39= 460÷2= 12×30=320÷8= 96÷3= 505÷5= 82-56= 108+92= 50×30=(6) 0.8+0.7= 0.4+0.6= 1.9-1.4= 0.6+0.9= 2.1-1.4= 1-0.7=4.3+1.7= 6+2.3= 1.8-0.8= 9-8.8= 3.6+0.8= 90÷5=(7) 720÷8= 18×3= 23×20= 0×49= 6.7-2.4= 9-2.5=25×40= 42×3= 9.47-5.2= 2.9+1.5= 50×20= 32×40=90×20= 23×50= 1分米+20厘米= 3公顷+60000平方米= 40÷7=(8)810÷9= 33×4= 80×70= 0×80= 6-2.3= 9.1-1.9=24×50= 45×4= 4.17-3.2= 2.4+1.51= 31×30= 85÷9=二、估算：估算题目与乘法口诀关系很大，估算时记得0的个数莫丢0283÷7≈ 179÷2≈ 398÷5≈ 564÷8≈ 79×38≈ 39×21≈ 92×50≈ 69×71≈118÷3≈ 78×60≈ 318÷8≈ 59×32≈ 30×29≈ 68×29≈ 81×48≈ 79×42≈ 902÷3≈ 599÷6≈ 324÷8≈ 496÷7≈ 乘法估算，一般要把两个因数都估成整十或整百的，例如68×29≈要把68估成70，29估成30,70乘30等于2100所以68×29≈2100,;对于除法估算，要把被除数估成与它本身很接近而且能够整除除数的数，例如179÷2≈ 要把179估成180这样180不但与179很接近而且除以2没余数即180能整除2得90，所以179÷2≈ 90三、列竖式计算(带★的要验算)：(一要注意把数字写清楚，别把0和6,1和7写的分不清，再要注意对齐位，整十数和两位数相乘时注意格式把0空出来，对于有余数的除法记得横式上写余数，对于要验算的一定审清题目要求，要验算的一定要记得验算。
