一、口算题
| 4800 - 300 = | 38 ÷ 8 = | 63 - 27 = | 39 + 23 = | 88 × 2 = |
| 21 ÷ 5 = | 320 × 5 = | 71 - 23 = | 44 × 5 = | 69 + 11 = |
| 90 - 41 = | 304 × 5 = | 37 + 14 = | 16 × 3 = | 54 × 2 = |
| 84 - 12 ÷ 6 = | 26 + 19 - 15 = | 90 + 4 ÷ 1 = | 93 - 54 + 31 = | 51 + 7 × 2 = |
二、笔算题
| 464 ÷ 8 = | ※ 633 + 332 = | 356 + 344 - 445 - 155= |
| 715 - 346 = | ※ 517 - 423 = | 67 × 68 = |
| 755 - 447 - 166 = | 53 + 667 + 347 - 567= | 779 × 3 = |
