一、看誰算得又對又快。(12 分)
23 + 4 = 40 + 58 = 50 + 26 = 46 – 7 =
75 – 8 = 86 – 3 = 78 – 70 = 20 + 60 =
42 – 30 = 80 – 60 = 42 + 8 = 54 + 4 =
二、我會算下面的題。(12分)
16 + 8 + 5 = 83 – 8 – 30 = 40 + 39 – 60 =
50 + 27 – 70 = 64 – 20 + 8 = 90 + 7 – 20 =
三、填入適當的符號。 (12分)
35 + 8 ○ 45 96 + 4 ○ 100 54 – 40 ○ 15
37 + 9 ○ 73 76 – 9 ○ 69 42 + 8 ○ 40
