一、口算题
| 94 - 46 = | 57 × 3 = | 760 × 2 = | 41 × 9 = | 46 × 7 = |
| 93 × 5 = | 17 + 17 = | 46 ÷ 6 = | 2400 - 300 = | 705 × 2 = |
| 44 ÷ 8 = | 51 + 49 = | 94 - 27 = | 19 + 11 = | 83 - 29 = |
| 49 + 9 × 3 = | 1 ÷ 1 + 63 = | 13 + 38 - 16 = | 34 - 16 + 69 = | 98 - 72 ÷ 9 = |
二、笔算题
| 644 ÷ 7 = | 492 × 7 = | 758 + 664 + 242 + 336= |
| 841 - 282 = | 557 + 192 - 638 = | 71 × 79 = |
| ※ 742 - 260 = | ※ 613 + 118 = | 771 + 635 - 271 - 235= |
