一、口算题
| 23 + 25 = | 59 - 13 = | 52 + 38 = | 14 + 75 = |
| 48 + 43 = | 44 - 31 = | 92 - 25 = | 60 - 53 = |
| 95 - 57 = | 89 - 64 = | 65 + 31 = | 66 + 34 = |
| 22 + 50 = | 71 - 13 = | 73 - 72 = | 59 + 31 = |
二、填括号
| 39 + ( ) = 71 | ( ) - 69 = 23 | 34 + ( ) = 70 | 82 - ( ) = 74 |
| ( ) - 14 = 34 | 53 + ( ) = 85 | 43 - ( ) = 40 | 77 - ( ) = 49 |
| ( ) - 18 = 15 | 74 - ( ) = 17 | ( ) - 79 = 16 | 77 + ( ) = 86 |
三、虫食计算题
四、竖式计算题
| 38 + 22 = | 91 - 82 = | 60 - 42 = | 49 + 24 = |
