一、口算题
| 27 ÷ 6 = | 508 × 2 = | 58 × 8 = | 52 + 39 = | 13 × 8 = |
| 40 × 4 = | 34 ÷ 9 = | 28 + 27 = | 29 + 22 = | 76 × 6 = |
| 77 - 58 = | 570 × 2 = | 55 - 18 = | 2900 - 800 = | 97 - 68 = |
| 19 + 8 ÷ 2 = | 9 ÷ 3 + 16 = | 4 × 9 - 18 = | 84 - 56 - 19 = | 56 - 17 - 19 = |
二、笔算题
| 53 × 98 = | ※ 164 + 799 = | 423 ÷ 9 = |
| 378 + 522 - 145 - 755= | 525 - 488 + 336 = | ※ 476 - 470 = |
| 476 × 9 = | 911 - 574 = | 853 - 753 + 366 + 234= |
