一、写出得数
| 14 ÷ 7 = | 7700 - 100 = | 100 - 35 = | 30 ÷ 6 = | 300 + 300 = |
| 51 - 22 = | 100 + 900 = | 1300 - 100 = | 9700 - 9000 = | 100 + 600 = |
| 3000 + 300 = | 27 ÷ 8 = | 4800 - 700 = | 900 + 300 = | 3 × 6 = |
| 300 + 3000 = | 7 × 8 = | 3600 - 3000 = | 24 ÷ 4 = | 58 ÷ 7 = |
| 72 ÷ 9 = | 10 ÷ 2 = | 300 + 900 = | 18 ÷ 9 = | 400 + 3000 = |
| 42 ÷ 7 = | 49 + 45 = | 4000 + 300 = | 5 × 6 = | 1200 - 1000 = |
| 5300 - 1000 = | 900 + 200 = | 6 × 3 = | 3600 - 600 = | 400 + 300 = |
| 4 × 9 = | 84 - 19 = | 3 × 4 = | 400 + 900 = | 7 ÷ 4 = |
| 34 ÷ 6 = | 4600 - 400 = | 94 - 47 = | 9700 - 700 = | 800 + 300 = |
| 600 + 700 = | 66 + 14 = | 6700 - 1000 = | 9000 - 400 = | 5 × 3 = |
| 9500 - 1000 = | 5000 - 500 = | 49 ÷ 7 = | 8 × 4 = | 54 ÷ 9 + 53 = |
| 78 - 69 + 14 = | 72 - 35 + 18 = | 8 × 2 - 12 = | 72 ÷ 9 + 33 = | 3 × 6 - 15 = |
二、填括号
| 5700 - ( ) = 5400 | 44 + ( ) = 59 | ( ) + 100 = 200 | 61 - ( ) = 20 |
| ( ) + 400 = 1200 | ( ) ÷ 2 = 5 | 12 ÷ ( ) = 6 | ( ) × 5 = 10 |
| ( ) - 100 = 1000 | 63 ÷ ( ) = 9 |
三、竖式计算题，带“※” 要验算
| 400 - 198 = | 29 ÷ 8 = | 9 ÷ 2 = | ※ 193 - 100 = |
| 827 + 143 - 960 = | ※ 193 + 108 = | 704 + 116 - 735 = | 467 + 896 = |
