一、写出得数
| 8500 - 8000 = | 8 × 5 = | 700 + 800 = | 7 × 6 = | 9 × 7 = |
| 400 + 700 = | 100 + 500 = | 100 + 7000 = | 7 × 3 = | 63 ÷ 8 = |
| 63 ÷ 8 = | 35 ÷ 8 = | 9300 - 900 = | 4100 - 900 = | 9 × 6 = |
| 3300 - 300 = | 3000 + 500 = | 800 + 700 = | 9 ÷ 3 = | 40 ÷ 5 = |
| 4200 - 1000 = | 25 ÷ 5 = | 50 ÷ 6 = | 1000 + 700 = | 8500 - 500 = |
| 600 + 400 = | 3900 - 200 = | 100 - 55 = | 71 - 12 = | 6900 - 900 = |
| 100 + 700 = | 24 ÷ 4 = | 49 ÷ 7 = | 84 - 76 = | 1700 - 200 = |
| 300 + 5000 = | 4200 - 600 = | 6900 - 6000 = | 38 + 34 = | 42 ÷ 6 = |
| 54 ÷ 6 = | 5100 - 800 = | 8 × 4 = | 9 ÷ 9 = | 300 + 500 = |
| 100 + 900 = | 6200 - 600 = | 8 × 8 = | 7 × 7 = | 400 + 500 = |
| 700 + 900 = | 100 - 75 = | 48 + 44 = | 1700 - 500 = | 46 + 36 - 65 = |
| 5 × 6 - 13 = | 8 × 4 + 59 = | 29 - 9 ÷ 9 = | 52 - 36 + 25 = | 2 ÷ 1 + 81 = |
二、填括号
| 8 × ( ) = 32 | ( ) ÷ 5 = 5 | 54 ÷ ( ) = 9 | ( ) ÷ 8 = 1 |
| ( ) + 500 = 600 | 55 + ( ) = 59 | ( ) + 600 = 1500 | 37 - ( ) = 36 |
| 9200 - ( ) = 9000 | ( ) - 500 = 5400 |
三、竖式计算题，带“※” 要验算
| 785 + 589 = | 315 + 658 - 384 = | 12 ÷ 9 = | 146 + 130 - 110 = |
| ※ 169 + 563 = | 7 ÷ 6 = | 600 - 168 = | ※ 169 - 135 = |
