一、写出得数
| 9100 - 1000 = | 26 ÷ 6 = | 700 + 900 = | 9 × 5 = | 48 ÷ 6 = |
| 7 × 6 = | 93 - 89 = | 5000 + 200 = | 100 + 700 = | 9 ÷ 9 = |
| 7 × 4 = | 1600 - 900 = | 800 + 500 = | 4700 - 700 = | 9 ÷ 3 = |
| 50 - 46 = | 12 ÷ 3 = | 4800 - 700 = | 4 × 4 = | 400 + 700 = |
| 3 × 9 = | 4700 - 4000 = | 7700 - 700 = | 8800 - 300 = | 700 + 100 = |
| 500 + 2000 = | 800 + 300 = | 2200 - 300 = | 81 ÷ 9 = | 12 ÷ 9 = |
| 700 + 1000 = | 27 ÷ 9 = | 7100 - 500 = | 900 + 200 = | 500 + 100 = |
| 8300 - 200 = | 300 + 100 = | 100 - 81 = | 64 ÷ 7 = | 2600 - 700 = |
| 7 × 5 = | 7400 - 400 = | 27 ÷ 3 = | 3 × 4 = | 5 ÷ 5 = |
| 83 - 57 = | 49 + 16 = | 4 × 9 = | 29 + 12 = | 500 + 200 = |
| 7000 + 100 = | 7700 - 7000 = | 17 ÷ 3 = | 1300 - 200 = | 91 - 42 + 39 = |
| 79 - 8 × 4 = | 12 ÷ 3 + 23 = | 22 + 28 - 46 = | 94 - 3 × 6 = | 3 ÷ 1 + 23 = |
二、填括号
| ( ) × 4 = 32 | 600 + ( ) = 900 | 54 ÷ ( ) = 6 | 3300 - ( ) = 2800 |
| ( ) + 900 = 1700 | 9 ÷ ( ) = 3 | 23 + ( ) = 64 | 66 - ( ) = 40 |
| ( ) - 500 = 6100 | 56 ÷ ( ) = 8 |
三、竖式计算题，带“※” 要验算
| 821 - 774 = | 765 + 566 = | 609 - 384 + 710 = | 65 ÷ 7 = |
| ※ 648 + 350 = | ※ 649 - 252 = | 52 ÷ 8 = | 388 + 303 + 214 = |
