11 32 ÷ 4 = 8 32 divided by 4 is/equals 8. divided by 除法运算

12 加减乘除的不同表达方式: 1) plus 加法运算 4 + 3 = 7 4 plus 3 equals 7. 2) minus 减法运算 10- 6 = 4 10 minus 6 equals 4. 3) times 乘法运算 3×5 = 15 3 times 5 equals 15. 4) divide 除法运算 32÷4=8 32 divided by 4 equals 8.

13 Put the following into English : 1)15 + 8 = 23 2)18- 6 = 12 3) 4×9 = 36 4)40÷4 = 10 15 plus 8 equals 23. 18 minus 6 equals 12. 4 times 9 equals 36. 40 divided by 4 equals 10.

14 16 + 9 = 47 - 9 = 7 ×8 = 54÷6 = 28 + 22= 75 - 45= 12 ×5= 88÷11= Model: A : How much is 16 plus 9 ? B : 16 plus 9 equals 25.

15 Try to get 24 from the four numbers : 5-3=2 2+1=3 3 × 8=24

16 7+5=12 10-8=2 12 × 2=24

17 6-4=2 2 × 7=14 14+10=24

18 9-4=5 5 × 5=25 25-1=24

19 3 × 8=24 7-6=1 7+1=8

20 3 × 8=24 10-7=3 9 ÷ 3=3

21 Listening 1.11+14=25 2.17-5=12 3. 6 × 9=54 4. 100 ÷ 25=4 5. 48+52=100 6. 98-13=85 7. 5×40=200 Model: A:How much is 11 plus 14? B:11 plus 14 equals 25.

22 Workbook p 63 Read the following sums in English. 1.16+9=25 Sixteen plus nine equals twenty-five. 2.47-9=38 3.7 × 8=56 4.54 ÷ 6=9 5.28+22=50 6.75-45=30 7.12 × 5=60 8.88 ÷ 11=8 Forty-seven minus 9 equals thirty-eight. Seven times eight equals fifty-six. Fifty-four divided by six equals nine. Twenty-eight plus twenty-two equals fifty. Seventy-five minus forty-five equals thirty. Twelve times 5 equals sixty. Eighty-eight divided by eleven equals eight.

23 Homework 1.Put the following into English: 3+5=8 16-4=12 4 × 3=12 40 ÷ 4=10 7 ×11=77 72÷6=12 2. 完成补充练习 3. 听、读本课词汇及课文 5 遍。

24 3+5=8 16-4=12 4×3=12 40÷4=10 7×11=77 72÷6=12 Three plus five equals eight. Sixteen minus four equals twelve. Four times three equals twelve. Forty divided by four equals ten. Seven times eleven equals seventy-seven. Seventy-two divided by six equals twelve.
