一、口算题
| 64 × 6 = | 66 - 28 = | 700 × 2 = | 15 ÷ 2 = | 76 - 57 = |
| 700 × 2 = | 22 ÷ 4 = | 71 - 54 = | 14 × 2 = | 95 × 3 = |
| 49 + 31 = | 38 + 27 = | 78 + 22 = | 7600 - 900 = | 35 × 5 = |
| 56 + 16 ÷ 4 = | 19 - 8 × 2 = | 54 + 27 - 73 = | 15 + 16 - 25 = | 6 ÷ 3 + 74 = |
二、笔算题
| 850 - 151 - 849 + 750= | 62 × 60 = | 772 - 462 + 128 + 562= |
| 272 ÷ 4 = | ※ 338 + 371 = | 898 × 3 = |
| 761 - 277 = | 503 - 289 + 139 = | ※ 899 - 259 = |
