分類: Daily English / Mathematics

關鍵詞彙 (Key Vocabulary)

本主題的重要詞彙與片語

  • addition: 加法。將兩個或多個數字組合起來求總和的數學運算。

    • 例句:"In addition, you combine numbers: 5 plus 3 equals 8."(在加法中,你組合數字:5 加 3 等於 8。)
  • subtraction: 減法。從一個數字中減去另一個數字的數學運算。

    • 例句:"Subtraction means taking away: 10 minus 4 equals 6."(減法意味著減去:10 減 4 等於 6。)
  • multiplication: 乘法。將一個數字重複加到自己指定次數的數學運算。

    • 例句:"Multiplication is repeated addition: 3 times 4 equals 12."(乘法是重複的加法:3 乘以 4 等於 12。)
  • division: 除法。將一個數字分成相等部分的數學運算。

    • 例句:"In division, you split numbers: 20 divided by 5 equals 4."(在除法中,你分割數字:20 除以 5 等於 4。)
  • sum: 和。兩個或多個數字相加的結果。

    • 例句:"The sum of 7 and 5 is 12."(7 和 5 的和是 12。)
  • difference: 差。從一個數字中減去另一個數字的結果。

    • 例句:"The difference between 15 and 8 is 7."(15 和 8 的差是 7。)
  • product: 積。兩個或多個數字相乘的結果。

    • 例句:"The product of 6 and 7 is 42."(6 和 7 的積是 42。)
  • quotient: 商。一個數字除以另一個數字的結果。

    • 例句:"The quotient of 24 divided by 6 is 4."(24 除以 6 的商是 4。)

實例與應用 (Examples & Application)

提供實際例句或應用情境

例句一:購物計算

"Let me do the addition: three items at $15 each, the sum is $45. With a $10 discount through subtraction, the difference is $35."
(讓我做加法:三件商品每件 15 美元,和是 45 美元。透過減法打 10 美元折扣,差是 35 美元。)

例句二:烹飪測量

"The recipe requires multiplication: if one serving needs 2 cups and we're making 4 servings, the product is 8 cups total."
(食譜需要乘法:如果一份需要 2 杯,我們做 4 份,積是總共 8 杯。)

例句三:平均分配

"We need to use division to share 36 cookies among 9 children. The quotient is 4 cookies per child."
(我們需要用除法將 36 塊餅乾分給 9 個孩子。商是每個孩子 4 塊餅乾。)

實踐練習 (Practice Activities)

透過多種方式練習今日主題,專注於實際應用和口說表達

口說練習

大聲朗讀並練習說出以下句子,注重發音和流暢度

  • "Addition uses the plus sign (+), and subtraction uses the minus sign (-)."
    (加法使用加號(+),減法使用減號(-)。)

  • "When doing multiplication, we use the times sign (×), and the result is called the product."
    (在做乘法時,我們使用乘號(×),結果稱為積。)

  • "In division, we use the divided by sign (÷), and the answer is the quotient."
    (在除法中,我們使用除號(÷),答案稱為商。)

  • "To find the sum, add all numbers together; to find the difference, subtract the smaller from the larger."
    (要找到和,將所有數字加在一起;要找到差,從較大的數減去較小的數。)

情境對話

模擬真實情境,練習使用今日學習的內容進行對話

情境:幫助孩子做數學作業

Parent: "Let's start with addition. What's 8 plus 5?"
Child: "The sum is 13!"

Parent: "Great! Now try subtraction. What's the difference between 20 and 7?"
Child: "That's 13 too!"

Parent: "Perfect! Now for multiplication. What's the product of 4 times 6?"
Child: "4 times 6 equals 24!"

Parent: "Excellent! Last one - division. What's the quotient when you divide 18 by 3?"
Child: "18 divided by 3 is 6!"


翻譯:

  • 家長:我們從加法開始。8 加 5 是多少?
  • 孩子:和是 13!
  • 家長:很好!現在試試減法。20 和 7 的差是多少?
  • 孩子:那也是 13!
  • 家長:完美!現在是乘法。4 乘以 6 的積是多少?
  • 孩子:4 乘以 6 等於 24!
  • 家長:太棒了!最後一個 - 除法。18 除以 3 的商是多少?
  • 孩子:18 除以 3 是 6!
