It's great to see you today, everyone.
We hope that you'll have a great time today here with us on Let's Talk in
English.
My name is Nathan.
I am one of your teachers here.
Today we have a new topic - SHOPPING.
And our lesson is called Math Problems.
Math Problems.
Uh, why are we talking about math for a SHOPPING lesson, Katie?
Well, Nathan, sometimes when you go shopping, you have to use math.
You have to know how much money you're spending, and that is a kind of math.
Hi, everyone.
My name is Katie, and I think that this lesson will be very useful for you
today.
We'll practice some math later, but let's practice our reading by reading
today's Read It now.
Mark brought a bag of apples to share.
Megan brought apples to share, too.
Fifteen apples plus 15 apples is 30 apples.
That's a lot of apples.
They will give 16 apples to their friends.
Thirty minus 16 equals 14.
They can divide the leftover apples by two, but will they each take half?
Well, we all need to use math for some things.
It's very useful for counting how much money you need to buy things at a store.
And today we will learn that we often need to use math when we want to share
things.
Megan and Mark both brought apples to share.
But how many apples should they give everyone?
Do they have enough?
Well, I think they do.
Together they have thirty apples.
I wonder what they decide to do with them.
But before we start our conversations, let's talk with our word lady about
today's key words.
Hello.
(Chinese).
Hey, Megan.
I brought some apples to share.
I brought apples, too!
Did you go to the sale at Freeway Supermarket?
I did!
I bought a bag of 15 apples.
How many did you get?
I also got 15 apples.
That means we have 25 apples to share!
Uh, no!
Fifteen apples plus 15 apples is 30 apples.
Oh... That's a lot of apples!
(Music).
Mark is right.
They have a lot of apples to share.
If I bought thirty apples to eat by myself, I would have them a long time.
Oh, maybe too long.
If you keep fruit for a long time, it can go bad in your refrigerator.
Uh, that would be too bad.
It would be a waste of money and good fruit.
But if you share 30 apples, everyone can have some.
And they can finish them before the apples go bad.
But why did Megan and Mark bring so many apples anyway?
Well, Mark didn't know that Megan bought apples, and she didn't know he bought
them, either.
They found them at a sale.
Oh, that's right.
They bought them because they were cheap at Freeway Supermarket.
And they brought them to share.
That's very nice of them.
Do you understand that pattern "bring something to share," everyone?
Well, if not, let's get a little help with it from Christina.
(Chinese).
So Megan and Mark both bought more apples than they needed.
They wanted to share them, but now they might have too many.
Maybe.
Mark and Megan both bought one bag of apples.
Each bag has fifteen apples.
And 15 plus 15 equals 30.
Plus and equal are English words, but they look different in math problems.
Like this: 15 + 15 = 30.
But we read it the same both ways.
I think we'll get some more practice with math problems later today.
Hey, Katie, why are they called math problems anyway?
Well, for math, questions are often called problems.
When you do your math homework, you are answering a lot of math problems.
But "problems" makes the question sound bad.
I guess they are bad for people who really don't like math.
Well, if you have a question, you need to find an answer.
And problems are the same - they need an answer.
Oh. Oh, that's true.
Now do you all remember how many apples they got?
That's very important for our lesson today.
And it's a lot like our... Calendar Phrase.
How many did you get?
How many did you get?
(Chinese).
I bought some cookies.
How many did you get?
They are very good.
How many did you get?
They are very expensive.
How many did you get?
I bought a big bag to share.
Have some.
Thanks!
Hey! You got more than I did.
How many did you get?
How many did you get?
(Chinese).
(Music).
Let's give four apples to Carol.
We can also give four to Susie.
We should give four to Rob and four to Jim, too.
OK. Good idea.
Then we'll have 20 apples left.
No! Thirty minus 16 equals 14.
Oh... Sorry, I'm not very good at math.
You might not be good at math, but you are good at sharing!
(Music).
Well, are you good at math?
Math is easy for some people, but it's hard for other people.
What kind of person are you?
Oh. Math is harder for me.
I was OK at math when I was in school.
But it was not always easy for me to learn or remember.
Is math hard for you, too, Katie?
Oh, yes, just like you, Nathan.
Math was also hard for me in school.
I was not very good at it.
So if you have trouble with math in school, you are not alone.
A lot of people think that math is one of the hardest classes in school.
But if you're not good at math, I think you might be good at a different class.
Practice this sentence, everyone.
I'm good at something, like science or history.
Oh. I'm good at writing.
I really liked that class in school.
But you also use that sentence for other things, not only your classes.
Sure.
Maybe you're good at baseball and maybe you're good at dancing.
Some people are good at cooking.
Other people are good at eating.
See? There are so many ways to use that sentence.
Now speaking of eating, let's get back to all of these apples.
Megan and Mark won't eat all thirty apples themselves, so they want to give four
to each of their friends.
Yes.
Four for Carol, four for Rob and four for Jim.
But are you sure they will give all of them four apples, Nathan?
Well, that's what they said, Katie.
Of course they will.
Megan said let's give four apples to Carol.
"Let's" means "let us." We'll do this together.
So Carol will get apples.
But they only said that they can give four to Susie.
Well, yes. They can and they will.
They have a lot of apples.
They just said it a different way.
Just like they should give apples to Rob and Jim, too.
Oh, so they should and they will.
I see.
And if they give all those apples away, they will have 14 apples left.
Christina can help us understand that a little more.
(Chinese).
Well, we only have a few seconds left before our break, and now they're gone.
We have more to learn.
So come back in a few minutes.
(Music).
