一、口算题
| 55 + 30 = | 59 + 41 = | 95 - 69 = | 35 + 60 = |
| 88 - 84 = | 21 + 65 = | 26 - 22 = | 48 + 13 = |
| 19 + 12 = | 83 - 82 = | 59 - 18 = | 72 + 28 = |
| 52 + 46 = | 70 - 44 = | 70 - 66 = | 64 - 45 = |
二、填括号
| 82 - ( ) = 68 | ( ) - 10 = 15 | ( ) - 79 = 16 | 55 + ( ) = 83 |
| 10 + ( ) = 14 | 97 - ( ) = 38 | ( ) - 23 = 29 | 22 + ( ) = 61 |
| 56 + ( ) = 64 | 45 - ( ) = 23 | 20 - ( ) = 14 | ( ) - 33 = 18 |
三、虫食计算题
四、竖式计算题
| 46 + 35 = | 40 - 31 = | 57 + 33 = | 95 - 86 = |
