一、口算题
| 49 + 49 = | 83 - 80 = | 85 - 77 = | 86 - 51 = |
| 34 + 65 = | 48 + 12 = | 39 + 11 = | 92 - 73 = |
| 22 + 30 = | 21 + 58 = | 83 - 78 = | 22 - 21 = |
| 91 - 75 = | 69 - 65 = | 13 + 82 = | 66 + 25 = |
二、填括号
| 50 - ( ) = 26 | ( ) - 24 = 38 | ( ) - 79 = 12 | 15 + ( ) = 68 |
| 58 + ( ) = 94 | ( ) - 12 = 12 | ( ) - 59 = 12 | 22 + ( ) = 90 |
| 31 - ( ) = 20 | 55 - ( ) = 17 | 27 + ( ) = 51 | 80 - ( ) = 44 |
三、虫食计算题
四、竖式计算题
| 92 - 74 = | 49 + 33 = | 49 + 41 = | 25 - 18 = |
