1. 口算。(建议用时6分钟)
9 - 2 =        9 + 3 =        14 - 7 =        4 + 8 - 3 =   
12 - 6 =        8 + 9 =        11 - 3 =        11 - 3 + 6 =   
14 - 5 =        19 - 4 =        12 - 5 =        13 - 7 + 6 =   
16 - 4 =        12 - 3 =        8 + 2 =        11 + 1 - 5 =   
11 - 9 =        15 - 7 =        13 - 4 =       16 - 7 - 3 =   
12 - 2 =        12 - 4 =        16 - 3 =       2 + 9 - 2 =   
14 - 9 =        17 - 1 =        17 - 5 =       14 - 6 + 4 =   
15 - 8 =        11 - 2 =        18 - 3 =       2 + 10 - 4 =   
11 - 5 =        13 - 5 =        12 - 7 =       12 - 9 + 7 =   
7 + 12 =        12 - 8 =        11 - 4 =       7 + 8 - 6 =   
15 - 5 =        11 - 7 =        10 + 4 =       5 + 6 - 8 =   
11 - 6 =        18 - 5 =        16 - 9 =       14 - 8 + 11 =   
答案: 7 12 7 9

2. 中有数。(填一填)(建议用时4分钟)
3 + = 11        - 4 = 8        14 - = 9
+ 4 = 12        14 - = 10      - 5 = 8
12 - = 3        10 - 3 = - 5     5 + = 13 - 6
4 + 5 = - 3      - 4 = 8 + 1      11 - = 5 + 4
               
答案: 8 12 5
