一、口算题
| 56 + 34 = | 53 ÷ 6 = | 48 + 28 = | 770 × 2 = | 64 ÷ 9 = |
| 46 + 39 = | 55 - 16 = | 80 × 9 = | 9600 - 200 = | 600 × 2 = |
| 24 × 8 = | 51 × 7 = | 68 × 3 = | 81 - 33 = | 60 - 42 = |
| 21 + 59 - 55 = | 33 - 27 + 18 = | 12 ÷ 2 + 11 = | 80 - 5 × 2 = | 76 - 10 ÷ 2 = |
二、笔算题
| 502 - 158 = | 783 ÷ 9 = | 685 × 6 = |
| 567 - 327 + 333 + 527= | 27 × 56 = | 446 - 215 - 182 = |
| 853 + 547 - 326 - 774= | ※ 502 + 230 = | ※ 809 - 742 = |
