一、口算题
| 11 ÷ 5 = | 53 ÷ 8 = | 71 - 63 = | 17 × 3 = | 49 + 49 = |
| 80 - 11 = | 4800 - 600 = | 82 × 8 = | 70 - 64 = | 29 + 29 = |
| 404 × 5 = | 73 × 7 = | 38 × 9 = | 960 × 2 = | 47 + 46 = |
| 8 × 7 + 19 = | 39 + 51 - 55 = | 66 + 24 ÷ 3 = | 42 - 12 - 17 = | 17 + 15 ÷ 5 = |
二、笔算题
| 459 + 523 - 438 = | 38 × 53 = | 545 + 355 + 734 + 366= |
| ※ 938 - 381 = | 304 - 185 = | 563 × 4 = |
| 235 ÷ 5 = | 438 + 537 - 137 + 62= | ※ 304 + 477 = |
