三位数乘两位数立竖式计算练习题300道

一、引言在数学学习的旅程中，三位数乘两位数的竖式计算是一个重要的里程碑。它不仅是整数乘法运算的延伸与深化，更是培养学生运算能力、逻辑思维以及细心耐心品质的关键环节。熟练掌握这一技能，对于后续学习更复杂的数学知识，乃至解决日常生活中的实际问题，都具有不可替代的作用。本次精心编排的300道练习题，旨在为同学们提供充足的练习素材，帮助大家夯实基础，提升计算的准确性与速度。二、计算方法回顾与要点提示在进行竖式计算前，请务必回顾以下要点：1.规范书写，数位对齐：将三位数写在上面，两位数写在下面，末尾对齐。通常，我们习惯将位数多的因数写在上方，以方便计算。2.分步计算，准确乘积：先用两位数个位上的数字去乘三位数的每一位，所得积的末位与两位数的个位对齐。再用两位数十位上的数字去乘三位数的每一位，所得积的末位与两位数的十位对齐。3.积的定位，至关重要：用乘数哪一位上的数字去乘，积的末位就和那一位对齐，这是保证计算正确的关键。4.仔细累加，得出结果：将两次乘得的积按照对应的数位进行相加，注意进位。5.验算习惯，确保无误：完成计算后，建议通过交换因数位置再算一遍，或用除法进行验算，以检验结果的正确性。三、练习题第一组（30道）1.123×232.345×123.210×344.567×455.108×566.432×677.609×788.789×899.250×9010.812×1111.305×2212.543×3313.167×4414.721×5515.400×6616.289×7717.654×8818.370×9919.803×1520.196×2621.517×3722.234×4823.678×5924.910×6125.325×7226.741×8327.468×9428.111×1029.555×2530.999×30第二组（30道）31.135×4132.357×5233.579×6334.246×7435.468×8536.680×9637.802×1738.124×2839.346×3940.568×4041.790×5142.201×6243.423×7344.645×8445.867×9546.189×1347.301×2448.523×3549.745×4650.967×5751.219×6852.431×7953.653×8054.875×9155.103×2056.325×3157.547×4258.769×5359.981×6460.230×75第三组（30道）61.452×8662.674×9763.896×1864.118×2965.330×4066.552×5167.774×6268.996×7369.208×8470.420×9571.642×1672.864×2773.176×3874.398×4975.610×6076.832×7177.144×8278.366×9379.588×1480.800×2581.212×3682.434×4783.656×5884.878×6985.190×8086.412×9187.634×1288.856×2389.168×3490.380×45第四组（30道）91.602×5692.824×6793.236×7894.458×8995.670×9096.892×1197.304×2298.526×3399.748×44100.960×55101.272×66102.494×77103.716×88104.938×99105.350×15106.572×26107.794×37108.206×48109.428×59110.640×61111.862×72112.374×83113.596×94114.818×10115.230×25116.452×30117.674×41118.896×52119.308×63120.520×74第五组（30道）121.742×85122.964×96123.476×17124.698×28125.110×39126.332×40127.554×51128.776×62129.998×73130.310×84131.532×95132.754×16133.976×27134.488×38135.700×49136.922×60137.434×71138.656×82139.878×93140.390×14141.612×25142.834×36143.346×47144.568×58145.790×69146.302×80147.524×91148.746×12149.968×23150.480×34第六组（30道）151.702×45152.924×56153.436×67154.658×78155.870×89156.382×90157.604×11158.826×22159.338×33160.550×44161.772×55162.994×66163.506×77164.728×88165.940×99166.452×15167.674×26168.896×37169.408×48170.620×59171.842×61172.354×72173.576×83174.798×94175.310×10176.532×25177.754×30178.976×41179.488×52180.700×63第七组（30道）181.922×74182.434×85183.656×96184.878×17185.390×28186.612×39187.834×40188.346×51189.568×62190.790×73191.302×84192.524×95193.746×16194.968×27195.480×38196.702×49197.924×60198.436×71199.658×82200.870×93201.382×14202.604×25203.826×36204.338×47205.550×58206.772×69207.994×80208.506×91209.728×12210.940×23第八组（30道）211.452×34212.674×45213.896×56214.408×67215.620×78216.842×89217.354×90218.576×11219.798×22220.310×33221.532×44222.754×55223.976×66224.488×77225.700×88226.922×99227.434×15228.656×26229.878×37230.390×48231.612×59232.834×61233.346×72234.568×83235.790×94236.302×10237.524×25238.746×30239.968×41240.480×52第九组（30道）241.702×63242.924×74243.436×85244.658×96245.870×17246.382×28247.604×39248.826×40249.338×51250.550×62251.772×73252.994×84253.506×95254.728×16255.940×27256.452×38257.674×49258.896×60259.408×71260.620×82261.842×93262.354×14263.576×25264.798×36265.310×47266.532×58267.754×69268.976×80269.488×91270.700×12第十组（30道
