一、写出得数
| 7800 - 1000 = | 39 ÷ 5 = | 4 × 9 = | 100 + 700 = | 4 × 4 = |
| 500 + 700 = | 6800 - 500 = | 500 + 100 = | 45 ÷ 5 = | 72 ÷ 8 = |
| 9 × 3 = | 6 × 6 = | 500 + 1000 = | 7000 - 500 = | 2300 - 600 = |
| 17 ÷ 4 = | 5500 - 5000 = | 8 ÷ 8 = | 6 × 4 = | 5500 - 500 = |
| 37 ÷ 4 = | 2700 - 700 = | 100 + 7000 = | 500 + 500 = | 1000 + 700 = |
| 5500 - 300 = | 5000 + 100 = | 2700 - 2000 = | 88 - 19 = | 18 ÷ 9 = |
| 9 × 6 = | 70 - 32 = | 6 ÷ 6 = | 900 + 200 = | 7300 - 600 = |
| 2200 - 800 = | 3 × 6 = | 14 ÷ 9 = | 100 - 83 = | 47 + 46 = |
| 300 + 300 = | 400 + 800 = | 3 × 4 = | 8400 - 600 = | 58 + 28 = |
| 800 + 100 = | 6 ÷ 3 = | 4 ÷ 2 = | 3800 - 800 = | 300 + 800 = |
| 4800 - 500 = | 45 ÷ 9 = | 100 - 57 = | 500 + 500 = | 18 + 55 + 17 = |
| 92 - 6 × 2 = | 83 - 18 + 16 = | 58 + 6 ÷ 2 = | 99 - 5 × 3 = | 93 + 18 ÷ 9 = |
二、填括号
| 37 - ( ) = 30 | 6 ÷ ( ) = 2 | 18 ÷ ( ) = 2 | ( ) + 500 = 1300 |
| ( ) ÷ 9 = 5 | ( ) × 3 = 15 | 1900 - ( ) = 1700 | 32 + ( ) = 43 |
| ( ) + 900 = 1300 | 1200 - ( ) = 900 |
三、竖式计算题，带“※” 要验算
| 17 ÷ 3 = | 17 ÷ 3 = | 203 - 119 + 189 = | 828 + 593 = |
| 711 - 111 + 348 = | ※ 283 + 225 = | 848 - 469 = | ※ 629 - 548 = |
