7 + 6 = 5 + 9 = 8 + 7 = 5 + 8 = 7 + 9 = 9 + 8 = 5 + 7 = 8 + 4 = 9 + 3 = 9 + 9 = 3 + 8 = 6 + 5 = 7 + 4 = 8 + 8 = 6 + 8 = 2 + 9 = 7 + 7 = 3 + 7 = 6 + 6 = 6 + 9 = 8 + 6 = 3 + 8 = 5 + 5 = 7 + 8 = 12 – 4 =
15 – 9 = 16 – 7 = 13 – 6 = 16 – 9 = 11 – 5 = 12 – 8 = 11 – 7 = 18 – 9 = 17 – 8 = 14 – 8 = 13 – 7 = 15 – 8 = 14 – 5 = 11 – 9 17 – 9 = 17 – 9 = 11 – 5 = 13 – 8 =
二、口算（每题1分，共24分）
28 + 20 = 58–6 = 66–60 = 75–30 = 38 + 40 =
71 + 23 = 89 – 8 = 50 + 24 = 4 + 55 = 96 – 20 = 66 – 60 = 38 + 21 = 30 + 34 = 69 – 7 = 59 – 4 =
73 – 70 = 95 – 50 = 25 + 44 = 62 + 7 = 30 + 49 = 86 – 60 = 91 – 50 = 36 + 30 = 51 + 25 =
三、在（ ）里填上合适的数。（每题2分，共24分）
3 +（ ）=73 5 +（ ）=70 4 +（ ）=17
43 +（ ）=93 38 –（ ）=8 68 –（ ）=48
（ ）– 6 = 50 （ ）+ 20 = 66 48 =（ ）+20
63=（ ）+13 72=（ ）+ 70 59=（ ）+ 9
四、计算。（每题2分，共28分）
18+9 – 9 = 12–8 + 70 = 70–30 + 6 = 46 + 40 + 2 =
99 –9–40 = 5 + 70–5 = 9 + 7 + 20 = 14–5 + 30 =
30 + 6 + 4 = 55–5 + 15 = 36 +30 +20= 5 + 5 5 +20=
