一、写出得数
| 3 × 7 = | 7400 - 400 = | 6 ÷ 3 = | 1500 - 1000 = | 3 × 8 = |
| 700 + 100 = | 6 × 6 = | 8 ÷ 6 = | 44 ÷ 5 = | 5 × 7 = |
| 700 + 800 = | 24 ÷ 6 = | 7 × 7 = | 29 ÷ 8 = | 7400 - 7000 = |
| 5100 - 800 = | 35 ÷ 7 = | 500 + 200 = | 2000 + 500 = | 1500 - 500 = |
| 9500 - 800 = | 93 - 89 = | 7600 - 300 = | 48 + 14 = | 5 × 8 = |
| 200 + 500 = | 8 × 6 = | 7400 - 100 = | 8500 - 1000 = | 41 - 32 = |
| 72 ÷ 9 = | 100 - 73 = | 7000 + 100 = | 10 ÷ 5 = | 8 × 5 = |
| 26 + 26 = | 400 + 800 = | 500 + 500 = | 700 + 1000 = | 6600 - 1000 = |
| 64 - 59 = | 700 + 500 = | 35 ÷ 5 = | 100 + 400 = | 6 ÷ 6 = |
| 200 + 5000 = | 54 ÷ 7 = | 5800 - 900 = | 8400 - 800 = | 200 + 300 = |
| 42 ÷ 6 = | 700 + 300 = | 9800 - 900 = | 7400 - 800 = | 74 - 46 + 17 = |
| 73 + 32 ÷ 8 = | 20 ÷ 5 + 21 = | 34 + 4 × 8 = | 74 - 36 + 56 = | 6 × 7 - 24 = |
二、填括号
| 35 ÷ ( ) = 5 | 85 - ( ) = 32 | ( ) + 300 = 600 | ( ) ÷ 6 = 6 |
| 4700 - ( ) = 4100 | ( ) + 900 = 1200 | 10 ÷ ( ) = 2 | 21 + ( ) = 96 |
| 4 × ( ) = 32 | ( ) - 1000 = 1800 |
三、竖式计算题，带“※” 要验算
| ※ 315 + 312 = | 20 ÷ 3 = | 490 + 139 + 295 = | 916 - 749 = |
| 74 ÷ 8 = | ※ 315 - 150 = | 378 + 157 = | 807 - 382 + 496 = |
