三年级数学上册400道三位数加减法计算

三年级数学上册三位数加减法专项练习（400道）一、计算要点回顾三位数加减法是整数运算的重要基础，计算时需遵循以下原则：1.相同数位对齐：个位对个位，十位对十位，百位对百位2.从个位算起：加法需注意进位标记，减法需关注退位处理3.进位加法：哪一位相加满10，向前一位进1（建议在算式上方标记进位1）4.退位减法：哪一位不够减，从前一位退1当10，与本位数字合并后再减（建议在被减数上方标记退位点）5.验算方法：加法可用交换加数位置或减法验算；减法可用加法（差+减数=被减数）或减法（被减数-差=减数）验算二、三位数加法专项训练（120道）（一）不进位加法（30道）1.213+45=2.342+53=3.156+32=4.405+72=5.230+54=6.562+36=7.325+44=8.108+71=9.631+58=10.245+34=11.432+56=12.354+45=13.207+62=14.518+31=15.163+26=16.640+49=17.309+50=18.275+24=19.481+18=20.523+65=21.316+72=22.240+59=23.467+22=24.185+14=25.532+46=26.374+25=27.208+71=28.615+33=29.429+50=30.356+42=（二）一次进位加法（40道）1.258+46=2.375+68=3.436+57=4.189+23=5.567+35=6.294+78=7.345+86=8.472+59=9.168+74=10.539+62=11.287+45=12.364+79=13.453+68=14.192+39=15.576+47=16.248+85=17.359+63=18.483+58=19.175+76=20.548+65=21.269+54=22.382+79=23.447+65=24.156+87=25.534+78=26.275+66=27.391+59=28.468+73=29.183+69=30.552+49=31.246+87=32.378+56=33.429+74=34.195+68=35.563+48=36.284+79=37.357+65=38.476+55=39.169+83=40.528+74=（三）连续进位加法（50道）1.368+154=2.475+267=3.589+376=4.293+458=5.647+285=6.356+477=7.482+369=8.537+295=9.268+574=10.715+196=11.389+243=12.456+378=13.592+269=14.274+587=15.638+285=16.347+465=17.493+358=18.567+276=19.285+547=20.726+198=21.359+264=22.487+356=23.543+279=24.296+585=25.678+245=26.364+479=27.458+367=28.572+289=29.263+578=30.719+184=31.385+247=32.469+354=33.538+286=34.276+595=35.649+273=36.358+466=37.483+379=38.564+288=39.297+546=40.735+187=41.369+254=42.478+365=43.552+299=44.283+579=45.684+238=46.349+475=47.463+388=48.576+267=49.258+586=50.742+179=三、三位数减法专项训练（120道）（一）不退位减法（30道）1.458-23=2.576-42=3.689-54=4.765-31=5.843-20=6.597-63=7.654-42=8.738-51=9.862-30=10.945-23=11.586-45=12.674-32=13.759-27=14.832-60=15.927-54=16.568-35=17.649-26=18.735-41=19.826-70=20.954-32=21.579-46=22.683-52=23.746-33=24.857-20=25.938-65=26.592-47=27.675-34=28.763-52=29.848-21=30.925-70=（二）一次退位减法（40道）1.435-28=2.562-47=3.647-59=4.728-39=5.853-65=6.346-78=7.453-86=8.527-69=9.638-74=10.754-82=11.469-35=12.583-57=13.652-68=14.736-49=15.847-75=16.375-86=17.482-94=18.556-67=19.643-78=20.729-85=21.458-29=22.574-36=23.639-57=24.762-84=25.835-69=26.386-79=27.493-85=28.567-48=29.654-76=30.748-93=31.472-35=32.586-59=33.635-67=34.759-82=35.843-76=36.394-85=37.468-93=38.575-49=39.646-78=40.732-87=（三）连续退位减法（50道）1.523-175=2.641-286=3.735-367=4.852-479=5.926-584=6.438-159=7.562-274=8.675-386=9.783-497=10.846-558=11.574-289=12.653-375=13.748-469=14.836-557=15.925-678=16.462-183=17.587-298=18.694-415=19.753-376=20.861-584=21.539-254=22.647-368=23.752-473=24.838-559=25.946-677=26.475-196=27.583-304=28.692-413=29.764-385=30.851-572=31.548-269=32.656-377=33.743-464=34.839-555=35.927-648=36.486-197=37.574-285=38.663-374=39.758-479=40.845-566=41.537-258=42.645-366=43.732-453=44.829-544=45.916-637=46.478-199=47.565-286=48.654-377=49.743-468=50.832-559=四、三位数加减混合运算（160道）（一）两步运算（80道）1.358+246-179=2.567-324+185=3.479+158-267=4.684-259+376=5.293+547-368=6.752-486+239=7.365+478-592=8.643-275+189=9.528+367-459=10.736-482+257=11.349+285-176=12.657-328+419=13.486+179-254=14.763-495+328=15.297+564-385=16.842-576+239=17.358+473-569=18.635-287+194=19.547+368-452=20.729-463+258=21.365+278-194=22.648
