一、口算(每题1分,共48分)

7 + 6 = 5 + 9 = 8 + 7 = 9 + 8 = 5 + 7 = 8 + 4 = 3 + 8 = 6 + 5 = 7 + 4 = 2 + 9 = 7 + 7 = 3 + 7 = 8 + 6 = 3 + 8 = 5 + 5 = 15 – 6 = 14 – 7 = 11 – 8 = 15 – 9 = 16 – 7 = 13 – 6 = 12 – 8 = 11 – 7 = 18 – 9 = 13 – 7 = 15 – 8 = 14 – 5 = 17 – 9 = 11 – 5 = 13 – 8 =

二、口算(每题1分,共26分) 28 + 20 = 58 – 6 = 66 – 60 = 71 + 23 = 89 – 8 = 50 + 24 = 66 – 60 = 38 + 21 = 30 + 34 = 73 – 70 = 95 – 50 = 25 + 44 = 86 – 60 = 91 – 50 = 36 + 30 = 67-15=

5 + 8 = 9 + 3 = 8 + 8 = 6 + 6 = 7 + 8 = 14 – 9 = 16 – 9 = 17 – 8 = 11 – 9 = 75 – 30 = 4 + 55 = 69 – 7 = 62 + 7 = 51 + 25 = 7 + 9 = 9 + 9 = 6 + 8 = 6 + 9 = 12 – 4 = 15 – 7 = 11 – 5 = 14 – 8 = 17 – 9 = 38 + 40 = 96 – 20 = 59 – 4 = 30 + 49 = 68+17=

三、在( )里填上合适的数。(每题1分,共12分)

13 +( )=73 5 +( )=70 4 +( )=17

43 +( )=93 38 –( )=8 68 –( )=48 ( )– 6 = 50 ( )+ 20 = 66

63=( )+13 72=( )+ 70

四、计算。(每题1分,共14分)

18+9 – 9 = 12 – 8 + 70 =

46 + 40 + 2 = 99 – 9 – 40 =

9 + 7 + 20 = 14 – 5 + 30 =

55 – 5 + 15 = 36 +30 +20=

13 – 5 + 50= 82 – 80 +8=

48 =( 59=(70 – 30 + 6 = 5 + 70 – 5 = 30 + 6 + 4 = 5 5-15 +20= )+20 )+ 19
