一、写出得数
| 600 + 600 = | 600 + 500 = | 9500 - 500 = | 200 + 400 = | 4900 - 200 = |
| 4000 - 200 = | 33 ÷ 6 = | 1300 - 300 = | 3 × 6 = | 24 ÷ 3 = |
| 90 - 81 = | 49 ÷ 8 = | 3200 - 400 = | 71 - 45 = | 8100 - 100 = |
| 32 ÷ 4 = | 9 × 5 = | 7400 - 1000 = | 2100 - 600 = | 32 ÷ 6 = |
| 700 + 200 = | 900 + 900 = | 900 + 500 = | 8000 - 700 = | 1300 - 1000 = |
| 12 ÷ 6 = | 600 + 400 = | 73 - 67 = | 9300 - 1000 = | 68 + 32 = |
| 300 + 200 = | 5 × 7 = | 36 ÷ 9 = | 4 × 8 = | 20 ÷ 7 = |
| 58 + 37 = | 41 - 35 = | 5 × 3 = | 4 × 7 = | 14 ÷ 7 = |
| 20 ÷ 5 = | 200 + 800 = | 2400 - 600 = | 200 + 200 = | 1200 - 900 = |
| 9500 - 9000 = | 200 + 2000 = | 6 × 3 = | 8 × 3 = | 3000 + 200 = |
| 300 + 2000 = | 2000 + 200 = | 72 ÷ 9 = | 45 ÷ 9 = | 25 - 17 + 79 = |
| 4 × 4 - 12 = | 70 + 18 ÷ 6 = | 2 × 6 - 11 = | 94 - 4 ÷ 4 = | 27 + 15 - 39 = |
二、填括号
| 4600 - ( ) = 4000 | ( ) - 700 = 1100 | 300 + ( ) = 1200 | ( ) ÷ 2 = 2 |
| 20 ÷ ( ) = 4 | 67 - ( ) = 62 | ( ) × 1 = 5 | 300 + ( ) = 900 |
| ( ) ÷ 7 = 2 | 14 + ( ) = 27 |
三、竖式计算题，带“※” 要验算
| ※ 348 - 324 = | 50 ÷ 8 = | 602 + 340 - 205 = | 23 ÷ 9 = |
| 276 + 498 - 477 = | ※ 448 + 282 = | 720 - 282 = | 448 + 282 = |
