一、写出得数
| 600 + 100 = | 8 × 9 = | 59 + 41 = | 1600 - 300 = | 400 + 600 = |
| 6000 - 800 = | 800 + 500 = | 6 × 3 = | 84 - 17 = | 73 - 46 = |
| 18 ÷ 3 = | 2300 - 200 = | 32 ÷ 4 = | 5600 - 5000 = | 9700 - 400 = |
| 5600 - 600 = | 200 + 900 = | 10 ÷ 5 = | 21 ÷ 3 = | 5 × 9 = |
| 800 + 700 = | 43 ÷ 7 = | 8500 - 400 = | 45 ÷ 9 = | 900 + 300 = |
| 8700 - 200 = | 5100 - 700 = | 7 × 5 = | 4 × 5 = | 4 × 7 = |
| 6 × 7 = | 8800 - 8000 = | 18 ÷ 7 = | 600 + 500 = | 31 ÷ 9 = |
| 7 × 3 = | 400 + 2000 = | 4000 + 200 = | 100 - 41 = | 30 ÷ 5 = |
| 8800 - 800 = | 900 + 700 = | 48 ÷ 8 = | 20 ÷ 4 = | 41 - 28 = |
| 1400 - 1000 = | 600 + 1000 = | 900 + 300 = | 68 + 32 = | 5600 - 300 = |
| 400 + 700 = | 6000 + 100 = | 4900 - 300 = | 64 ÷ 9 = | 60 - 21 + 52 = |
| 99 - 39 - 37 = | 20 ÷ 4 + 42 = | 7 × 3 - 17 = | 81 - 8 ÷ 8 = | 6 × 3 + 25 = |
二、填括号
| 21 + ( ) = 63 | 69 - ( ) = 43 | 600 + ( ) = 1200 | ( ) ÷ 3 = 6 |
| 20 ÷ ( ) = 5 | ( ) ÷ 9 = 3 | ( ) - 600 = 5800 | 8400 - ( ) = 7500 |
| 5 × ( ) = 5 | ( ) + 200 = 800 |
三、竖式计算题，带“※” 要验算
| 257 + 236 - 218 = | ※ 279 + 331 = | 489 + 182 - 350 = | 895 + 496 = |
| 421 - 156 = | 51 ÷ 6 = | 45 ÷ 6 = | ※ 279 - 146 = |
