一、写出得数
| 3700 - 100 = | 7 × 9 = | 1200 - 300 = | 73 - 36 = | 33 ÷ 5 = |
| 1900 - 700 = | 8100 - 400 = | 42 ÷ 6 = | 400 + 100 = | 4000 + 100 = |
| 7 ÷ 7 = | 5900 - 900 = | 400 + 200 = | 500 + 900 = | 31 ÷ 6 = |
| 200 + 900 = | 5900 - 5000 = | 8 × 4 = | 9300 - 300 = | 900 + 400 = |
| 600 + 600 = | 46 + 39 = | 8400 - 400 = | 9 ÷ 3 = | 3 × 9 = |
| 28 ÷ 4 = | 800 + 400 = | 79 + 11 = | 4000 - 800 = | 400 + 2000 = |
| 800 + 800 = | 8400 - 300 = | 600 + 400 = | 10 ÷ 3 = | 35 ÷ 5 = |
| 9 ÷ 9 = | 4200 - 800 = | 95 - 79 = | 3300 - 200 = | 41 - 16 = |
| 4000 + 200 = | 2900 - 800 = | 900 + 700 = | 48 ÷ 8 = | 52 ÷ 8 = |
| 7 × 3 = | 3 × 4 = | 8400 - 8000 = | 52 - 43 = | 3 × 8 = |
| 18 ÷ 3 = | 9 × 5 = | 5 × 6 = | 400 + 1000 = | 58 + 19 - 29 = |
| 42 - 36 ÷ 4 = | 73 - 65 + 77 = | 16 - 30 ÷ 5 = | 63 - 3 × 9 = | 69 + 4 × 5 = |
二、填括号
| 12 ÷ ( ) = 6 | 82 + ( ) = 95 | 96 - ( ) = 64 | 2600 - ( ) = 2000 |
| 100 + ( ) = 400 | 4 × ( ) = 20 | ( ) + 800 = 1000 | 9 ÷ ( ) = 3 |
| ( ) - 700 = 7900 | 9 ÷ ( ) = 1 |
三、竖式计算题，带“※” 要验算
| 14 ÷ 3 = | 139 + 599 - 528 = | 57 ÷ 7 = | 498 + 527 = |
| ※ 107 - 101 = | 572 - 231 - 278 = | 600 - 448 = | ※ 107 + 344 = |
