一、写出得数
| 8200 - 500 = | 63 + 37 = | 500 + 200 = | 5100 - 800 = | 500 + 2000 = |
| 56 ÷ 7 = | 4 × 9 = | 100 + 6000 = | 7 × 6 = | 6400 - 6000 = |
| 800 + 300 = | 66 ÷ 7 = | 59 + 13 = | 6 × 8 = | 30 ÷ 6 = |
| 51 - 22 = | 7 × 8 = | 4600 - 700 = | 600 + 200 = | 8900 - 700 = |
| 5000 + 200 = | 1000 + 600 = | 600 + 200 = | 900 + 300 = | 4 × 6 = |
| 1300 - 500 = | 3 × 9 = | 86 - 79 = | 12 ÷ 6 = | 4300 - 500 = |
| 600 + 600 = | 41 - 19 = | 5400 - 5000 = | 52 ÷ 8 = | 5400 - 400 = |
| 3600 - 600 = | 8 × 7 = | 600 + 700 = | 200 + 100 = | 50 ÷ 6 = |
| 3 × 6 = | 45 ÷ 5 = | 21 ÷ 6 = | 2700 - 800 = | 2900 - 900 = |
| 15 ÷ 5 = | 40 ÷ 5 = | 52 - 17 = | 6400 - 400 = | 7000 - 1000 = |
| 300 + 800 = | 27 ÷ 9 = | 100 + 600 = | 18 ÷ 9 = | 49 + 7 × 2 = |
| 63 ÷ 9 + 91 = | 2 × 5 + 74 = | 42 ÷ 7 + 10 = | 53 + 17 - 54 = | 51 - 16 - 18 = |
二、填括号
| 12 ÷ ( ) = 2 | 2600 - ( ) = 2300 | 12 ÷ ( ) = 2 | 200 + ( ) = 700 |
| 600 + ( ) = 700 | 79 - ( ) = 56 | ( ) - 100 = 7700 | ( ) ÷ 6 = 5 |
| ( ) × 9 = 9 | 40 + ( ) = 46 |
三、竖式计算题，带“※” 要验算
| 12 ÷ 5 = | 856 - 597 = | 510 + 112 - 199 = | ※ 228 - 161 = |
| 75 ÷ 8 = | 466 - 434 + 202 = | 286 + 425 = | ※ 228 + 535 = |
