2011—2012学年度第二学期一年级计算竞赛试卷

一、直接写得数。

7 + 6= 5 + 9 = 8 + 7= 5 + 8= 15-9= 12-3= 7 + 9= 9 + 8 = 5 + 7= 8 + 4= 14-4= 12+6=

9 + 3 = 9 + 9 = 3 + 8 = 6 + 5 = 8+9= 13-3= 数分7 + 4 = 8 + 8 = 6 + 8 = 2 + 9 = 13-7= 14-5= 7 + 7 = 3 + 7 = 6 + 6 = 6 + 9 = 12-5= 13-5 = 8 + 6 = 3+ 8= 5 + 5= 7 + 8= 9+4= 5+4= 12–4 = 15–6= 14–7= 11–8= 17-9= 10-5-5= 14 –9 = 15 –7 = 15 – 9 = 16 – 7= 17-8= 12+3= 号13– 6 = 16 –9 = 11 – 5= 12 – 8= 12-9= 11-1= 学11– 7 = 18 – 9= 17 – 8= 14 – 8= 8+5= 12-10= 13– 7 = 15 – 8= 14–5 = 1 1 –9= 11-5= 4+6= 17– 9 = 12 – 9= 11 –5= 13 – 8= 16-9= 8+2=

二、看看谁最细心 名1 + 14 + 1 = 8 + 9 + 2 = 2 + 2 + 14 = 1 + 13 + 1 = 姓6 + 3 + 1 = 7 – 2 – 2= 19 – 2 – 1= 17 – 7 – 8= 18 – 1 – 4= 9 + 0+ 9 = 14 - 6 - 5= 9 - 6 - 2=

8 - 1 - 5= 11 – 2 – 8= 2 + 6 + 7 = 1 + 10 + 7 = 2 + 4 + 3 = 1 + 10 + 8 = 9 + 3 + 2 = 6 + 3 + 8 = 4 + 15 + 1 = 10 + 1 + 5 = 9 + 1 + 3 = 1 + 8 + 3 = 级10 + 1 + 6 = 9 – 6 – 1= 1 + 10 + 3 = 4 + 4 + 6 = 班13 – 3 – 3= 6 – 4 – 1= 8 – 4 – 3= 14 - 2 - 3= 7 – 2 – 2= 9 - 2 - 1= 17 - 10 + 9= 18 - 1 - 4= 1 + 4 + 4 = 10 + 4 + 5 = 1 + 2 + 5 = 9 + 1 + 6 = 4 + 1 + 10 = 2 + 7 + 10 = 9 - 7 – 1= 5 + 4 + 3 = 10+ 1 - 7= 1 + 9 - 3= 8 - 2 + 1= 1 + 7 - 5= 6 + 10 – 6= 11– 9 + 1= 5 + 4 - 8= 9 + 1 - 2=

三、在( )里填上合适的数

14 -( )= 10 7 +( ) = 15 18-( ) = 8 7 + ( )= 16 ( )-5 = 3 ( )- 10 = 4 ( )-4 = 9 1 +( ) = 11 15-( ) = 7 3-( ) = 1 ( ) + 3 = 12 ( )-9 = 5 ( )-2 = 9 14 -( ) = 8 17- ( )= 9 10 +( ) = 18 7 + ( )= 20 ( )+5 = 13 18 -( ) = 10 ( )-10 = 4 ( )- 4 = 9 1 +( ) = 11 15-( ) = 9 3-( ) = 1

( ) + 3 = 12 ( )-5 = 5 ( )- 2 = 3 11 -( ) = 3 ( )+5=15 16-( )=10 40+( )=49 2+( )=11 ( ) -5=6 四、在○里填上<、=、>

1+9-3○7 7+8-6○14 14-9○6 4-7○8

17-7+5○6 16-6-6○9 4○18-8+3 9○10-6+2

4 ○13-7-5 14-7+8○16 6○13-4-6 12-7○5

3 ○

13-7 14○7+9 13-4○6 12+7○11+8 五、在( )里填上合适的数

1、把2、3、4、5、12、13、14、15填在( )里,使等式成立。( )-( )=( )-( )=( )-( )=( )-( ) 2、把1、2、3、7、8、9、填在( )里使等式成立。 ( )+( )=( )+( )=( )+( ) 六、巧算

1+2+3+4+5+6+7+8+9= 2+5+7+8+3=
