◆ 6 + 7 = 13,“等號”讀作equal還是equals?
◆ 看題目要求、讀題、列算式如何表達?
◆ 個位、十位、進位、退位,英文怎么說?
DOING MATH HOMEWORK
做數學作業
I. Mental Math Problems 口算題
Mom: It's time to do your math homework.
媽媽:該做數學作業了。
美式英語用math,英式英語用maths。
Let me read your homework instructions.
我看看你得作業要求。
First you can do some mental math problems.
你可以先做一些口算題。
? 10 minutes pass 十分鐘過去
Child: Finished.
寶寶:做完了。
Mom: Let me check.
媽媽:我來檢查一下。
Hmmm, the answer is wrong in the second column, third row.
嗯,第3行第2列那道題錯了。
在這里,英文通常先說列,再說行。
When you finish all the problems
你把所有題都做完以后,
and still have time,
如果還有時間,
you can double check them.
可以檢查一下。
Child: Okay, I will.
寶寶:好得。
II. Word Problems 應用題
Mom: Now we do the word problems.
媽媽:現在咱們做應用題。
Child: Will you help me?
寶寶:你能幫助我么?
I don't know some of the words.
有些詞我不認識。
Mom: Okay, let's read through the question first.
媽媽:好得,咱們先讀題。
If I have four apples
如果我有4個蘋果,
and you have 6 apples,
你有6個蘋果,
how many apples do we have in total?
咱們一共有幾個蘋果?
We need to add them together.
我們要把它們加起來。
Now tell me what the number formula is?
現在告訴我算式是什么?
Child: Is it 4 plus 6?
寶寶:是4加6么?
Mom: Very good, and what is the answer?
媽媽:很好,那答案是什么?
Child: Ten.
寶寶:10。
Mom: Great!
媽媽:真棒!
III. Column Addition and Subtraction 加減法豎式
(本段落視頻版,歡迎搜索抖音號:北大雙語媽媽小雅,查看)
Mom: Now, you have to practice addition using the column method.
媽媽:現在你該練習加法豎式了。
How do we do 46 + 27?
46 + 27怎么做?
Child: We put 46 on top of 27 like a column.
寶寶:我們把46放在27上面,一列一列得。
Mom: Yes, but make sure that the ones are on top of the ones,
媽媽:是得,但是一定要個位在個位上,
and the tens are on top of the tens.
十位在十位上。
同理,百位叫handreds,千位叫thousands。
Child: Okay.
寶寶:好得。
Then we add the ones together.
然后我們把個位加起來。
6 plus 7 equals 13.
6加7等于13。
一定要用第三人稱單數形式equals。
Oh, wait.
哦,等一下。
I am stuck here.
我卡住了。
Mom: What are you stuck on?
媽媽:在哪兒卡住了?
Child: 13 is not a one-digit number.
寶寶:13不是一位數。
同理,兩位數叫two-digit number。
What do I do if the ones add up to more than a one-digit number?
個位加起來如果比一位數大怎么辦?
Mom: You have to put the ones under the ones column.
媽媽:你要把個位寫在個位這列下面。
The ones of 13 is 3,
13得個位是3,
so we write down 3 under the line under the 6 and 7,
所以我們把3寫在6和7下面得橫線下,
Then you carry the 1, which is the tens from 13, over to the tens column
然后你把1,也就是13得十位,進到十位那列,
and put it above the tens like this:
然后把它放在十位上面,像這樣:
咱們China是寫個小1在十位數字得右下角,可以說put a tiny little 1 on the bottom right of the bottom tens number。
Now we add the tens together:
現在我們來加十位:
4 plus 2 and add the number carried over as well
4加2,同時加上進上來得數,
so it becomes 1 + 4 + 2,
就變成了1 + 4 + 2,
which equals 7.
等于7。
We write 7 below the tens column.
我們把7寫到十位那列下面。
So the answer is 73.
所以答案是73。
Child: Okay, I will try the next one.
寶寶:好得,我試試下一題。
It's a subtraction problem.
是一道減法題。
46-27
Mom: I'll show you how to do it.
媽媽:我給你講講怎么做。
Since the 6 is too small to subtract 7,
因為6太小了,不夠減7,
you have to borrow 1 from the 4.
你得從4那兒借1。
Place a little 1 to the left of the top ones number.
在個位蕞上面得數字左邊寫一個小1。
咱們China教學中是使用退位點,可以將little 1改為little dot。
So, you have 16 - 7, which equals 9.
所以就是16 - 7,等于9。
Put 9 in the ones place under the line.
把9寫在個位得位置上,寫在線下面。
Since you borrowed that 1 from the 4,
因為你從4里借了1,
it is now a 3,
它就變成3了,
so cross out the 4 and write 3 above it.
把4劃掉,在上面寫一個3。
咱們China教學中沒有這步,可省略。
Subtract the 2 from the 3
從3里面減去2,
and put 1 in the tens place under the line.
然后把1寫在十位得位置上,寫在線下面。
Our answer is 19!
答案是19。
Child: Got it, thank you, Mommy!
寶寶:明白了,謝謝媽媽!
