一、口算题
| 39 + 14 = | 99 - 98 = | 13 + 13 = | 33 - 29 = |
| 40 - 11 = | 89 - 56 = | 13 + 60 = | 52 + 39 = |
| 99 - 66 = | 48 - 40 = | 34 + 15 = | 27 + 23 = |
| 91 - 26 = | 25 + 25 = | 13 + 84 = | 70 - 56 = |
二、填括号
| ( ) - 15 = 66 | ( ) - 11 = 13 | ( ) - 79 = 18 | 95 - ( ) = 26 |
| 38 + ( ) = 74 | ( ) - 57 = 24 | 19 + ( ) = 85 | 41 + ( ) = 42 |
| 19 + ( ) = 80 | 95 - ( ) = 51 | 81 - ( ) = 63 | 44 - ( ) = 16 |
三、虫食计算题
四、竖式计算题
| 44 + 36 = | 92 - 34 = | 49 + 16 = | 93 - 86 = |
