一、口算题
| 33 ÷ 8 = | 77 × 7 = | 50 ÷ 6 = | 48 + 37 = | 800 × 2 = |
| 66 + 26 = | 35 × 2 = | 93 - 15 = | 1900 - 200 = | 67 + 25 = |
| 100 - 41 = | 92 × 8 = | 800 × 2 = | 15 × 7 = | 34 - 29 = |
| 88 + 32 ÷ 8 = | 54 + 8 × 2 = | 19 + 16 - 17 = | 21 + 4 ÷ 4 = | 29 + 37 + 27 = |
二、笔算题
| 850 - 287 = | ※ 138 + 554 = | 614 - 310 - 238 = |
| 58 × 57 = | 854 × 3 = | 558 + 478 + 222 - 158= |
| ※ 855 - 225 = | 48 ÷ 6 = | 652 + 648 + 852 + 448= |
