Hello students, my name is Alexandra.
Let's learn about large English numbers.
This is for advanced students,
so if you haven't seen my basic and intermediate numbers videos,
please check them out first.
In this lesson, I will teach numbers from 10,000 to 1 trillion
and how to pronounce them correctly.
I know some of you are worried or have trouble expressing large English numbers,
but it's not that difficult.
We will do it together.
I promise by the end of this video, you will be able to say large numbers easily.
After you watch this lesson, be sure to check the description for homework, worksheet, PDF's and tests.
Let's get started.
We're going to talk about the power of commas to help you read and understand large English numbers.
Let's have a look at these first three.
1, 10, 100.
Those are easy.
We don't need commas.
We don't need to do anything more.
But look at this one 1000.
Now it starts to be a few more zeros.
So let's add a comma to help us read and understand it quickly.
You can add commas starting from the right and adding one comma for every 3 zeros.
1-2-3
Comma.
1,000
I know that when I see one comma, it means 1000.
Let's try another one.
1-2-3. Comma.
This one.
10,000
Because when I see one comma, it means 1000.
Let's keep going.
1-2-3 comma.
This one 100,000.
Next one.
1-2-3 comma.
This number is 1,000,000.
And I know that because when I see two commas,
I know it means million.
Let's try again.
1-2-3 comma.
So this is 10 million.
Because we know that two commas means million.
1-2-3 comma.
Oh, so this is 100 million.
Let's try again.
1-2-3 comma.
Oh, so that's 1 billion.
Because we have 3 commas.
I know that every time I see three commas, it means billion.
So I can see billion quickly and easily because it has three commas.
Let's try the next one.
1-2-3 comma.
Wow, so this is 1 trillion.
It has four commas.
So I know that every time I see four commas, that means trillion.
This one is 1 trillion.
All right, that's how you can use the power of commas
to help you read and understand English numbers quickly.
Good work.
All right, let's have a look at these numbers.
And practice using the commas and seeing the pattern.
So this number is 10,000.
We know that one comma means 1000.
Next in the pattern would be 10,001.
Then 10,002 and so on.
This number 25,100.
Next in the pattern,
25,101.
25,102.
And so on. It keeps going.
Now the numbers are getting a little bigger.
240 000 we know this comma means thousand. 450.
Next in the pattern would be 240,451.
240,452.
Let's practice with this number.
880,809.
Next in the pattern.
880,810.
880,811.
All right, this number’s got two commas.
So we know that this comma means million.
And this comma means thousand.
So we can read it quickly and easily.
2,124,433.
Next in the pattern.
434, 435, and so on.
Have a look here this number. All right, it's got 3 commas.
So we know that first comma means billion.
Second comma means million.
Third comma means thousand.
1,332,290,076.
Next in the pattern. 77, 78, and so on.
I know these are some large numbers.
I know they take some practice,
but with lots of review we can get it.
We have learned the pattern to express numbers from 10,000 to 1 trillion.
In this extra practice, you will see random numbers on the screen
and I want you to try and say the numbers quickly and correctly before I do.
Here we go.
14,544.
551,310.
3,130,000.
62,343,222.
8,792,554,543.
1,323,290,076.
And what's this big number?
1 trillion and 10.
I know that was a little difficult.
But I also know you are diligent students and will keep practicing.
Let's move on.
I'm now going to give you a quick listening test.
I will say 10 advanced numbers.
I will say each number twice.
These numbers are large, so use a pen or pencil to write them down.
Please listen and try to hear the correct number.
Number one.
10,002.
Number two.
66,000.
Number three.
1,000,100.
Number four.
5,500,500.
Number five.
120,000,010.
Number six.
802,202,020,002.
Number seven.
155,043.
Number eight.
999,999.
Number nine.
66,050,000.
Number ten.
1,000,100,000.
That's the end.
Please check your answers.
How did you do on the test?
I'm sure you did well.
Now you know how to express very large numbers in English.
Let me know how you did on the listening test in the comments below.
It is important to keep practicing.
