一、口算题
| 59 + 31 = | 50 - 42 = | 99 - 18 = | 13 + 50 = |
| 30 + 49 = | 84 - 77 = | 92 - 65 = | 96 - 82 = |
| 37 + 24 = | 48 + 34 = | 53 - 30 = | 87 - 56 = |
| 34 + 16 = | 55 + 44 = | 52 - 43 = | 58 + 41 = |
二、填括号
| 76 + ( ) = 84 | ( ) - 79 = 12 | 48 + ( ) = 91 | ( ) - 16 = 75 |
| 65 - ( ) = 16 | 28 + ( ) = 29 | 96 - ( ) = 50 | 65 - ( ) = 38 |
| 17 + ( ) = 22 | ( ) - 11 = 60 | ( ) - 36 = 44 | 82 - ( ) = 13 |
三、虫食计算题
四、竖式计算题
| 40 - 11 = | 64 + 36 = | 92 - 47 = | 19 + 11 = |
