一、口算题
| 18 + 12 = | 20 + 74 = | 72 - 56 = | 100 - 51 = |
| 40 + 26 = | 31 + 30 = | 40 + 58 = | 82 - 44 = |
| 77 - 39 = | 77 - 46 = | 88 - 52 = | 49 + 32 = |
| 49 + 49 = | 46 - 42 = | 79 + 21 = | 57 - 22 = |
二、填括号
| 66 + ( ) = 75 | ( ) - 33 = 56 | 15 + ( ) = 71 | ( ) - 55 = 39 |
| 46 + ( ) = 54 | 93 - ( ) = 27 | ( ) - 79 = 11 | 41 - ( ) = 34 |
| 71 - ( ) = 65 | 71 + ( ) = 73 | 87 - ( ) = 33 | ( ) - 14 = 57 |
三、虫食计算题
四、竖式计算题
| 19 + 14 = | 67 - 38 = | 90 - 51 = | 49 + 11 = |
