一、直接写出得数。(每题1分,共32分)
$41 + 59 =$ $380 - 300 =$ $1600 - 600 =$ $44 - 11 - 18 =$
$70 - 24 =$ $40 + 200 =$ $250 + 80 =$ $28 + 36 + 24 =$
$34 + 44 =$ $50 + 300 =$ $100 - 30 =$ $97 - 55 - 25 =$
$55 - 48 =$ $190 - 60 =$ $140 + 30 =$ $25 + 32 + 18 =$
$96 - 68 =$ $400 + 60 =$ $1400 - 400 =$ $67 - 28 + 24 =$
$47 + 36 =$ $130 + 70 =$ $575 + 900 =$ $46 + 17 - 12 =$
$62 - 37 =$ $200 + 30 =$ $5000 - 4000 =$ $81 - 26 + 37 =$
$16 + 36 =$ $140 - 50 =$ $400 + 600 =$ $30 + 35 - 18 =$

一 8100 80 1000 15 46 240 330 88 78 350 70 17 7 130 170 75 28 460 1000 63 83 200 1475 51 25 230 1000 92 52 90 1000 47

二、在$◯$里填“＞”“＜”或“=”。(每题2分,共12分)
$322 + 198◯ 500$ $206 + 438◯ 650$ $258 + 453◯ 711$
$546 + 278◯ 864$ $427 + 573◯ 1000$ $629 + 274◯ 900$

二 ＞ ＜ = ＜ = ＞

三、哪两张卡片上的数相加得1000? (连一连)(共10分)

四、用竖式计算,带*的要验算。(每题3分,验算各1分,共30分)
$284 + 53 =$ *$327 + 815 =$ $49 - 17 - 23 =$
$506 + 85 =$ *$645 + 512 =$ $475 + 187 + 99 =$
$84 + 546 =$ *$638 + 262 =$ $19 + 33 - 28 =$

四 337 1142 9 591 1157 761 630 900 24 竖式及验算略
