一、写出得数
| 5 × 4 = | 4 × 3 = | 6800 - 800 = | 80 - 45 = | 7 × 7 = |
| 900 + 300 = | 28 ÷ 7 = | 12 ÷ 4 = | 83 - 64 = | 56 ÷ 6 = |
| 74 - 46 = | 12 ÷ 4 = | 9200 - 600 = | 500 + 500 = | 4 × 5 = |
| 63 ÷ 7 = | 49 + 28 = | 17 ÷ 7 = | 400 + 800 = | 4000 - 100 = |
| 27 ÷ 9 = | 2000 + 600 = | 3 × 8 = | 6200 - 1000 = | 9400 - 9000 = |
| 200 + 600 = | 23 ÷ 7 = | 9600 - 1000 = | 200 + 6000 = | 7 × 4 = |
| 24 ÷ 3 = | 7 × 8 = | 400 + 700 = | 18 ÷ 5 = | 700 + 700 = |
| 7300 - 500 = | 6400 - 600 = | 2000 + 700 = | 6800 - 6000 = | 59 + 41 = |
| 92 - 65 = | 400 + 600 = | 7200 - 600 = | 100 + 300 = | 16 ÷ 2 = |
| 32 ÷ 4 = | 2400 - 600 = | 200 + 700 = | 6700 - 100 = | 4 × 7 = |
| 9400 - 400 = | 9700 - 900 = | 200 + 7000 = | 200 + 900 = | 2 × 6 - 11 = |
| 8 ÷ 2 + 73 = | 37 - 29 + 12 = | 35 - 10 ÷ 5 = | 36 - 6 × 3 = | 45 + 29 - 24 = |
二、填括号
| ( ) ÷ 4 = 8 | ( ) × 6 = 12 | ( ) ÷ 3 = 8 | 4000 - ( ) = 3800 |
| 18 ÷ ( ) = 6 | 600 + ( ) = 1100 | 61 + ( ) = 89 | 97 - ( ) = 84 |
| ( ) + 800 = 1400 | ( ) - 200 = 7400 |
三、竖式计算题，带“※” 要验算
| 600 - 548 = | 560 - 510 + 740 = | 576 + 187 = | ※ 686 - 594 = |
| 38 ÷ 6 = | 53 ÷ 8 = | 543 - 321 + 698 = | ※ 307 + 633 = |
