0:00:00.470,0:00:01.660
- What we're going to do in this video

0:00:01.660,0:00:04.800
is get some practice writing[br]reasonably large numbers

0:00:04.800,0:00:06.850
in different ways.

0:00:06.850,0:00:09.920
So, for example, let's[br]say we had this number

0:00:09.920,0:00:12.570
and I'm going to not say[br]it out loud on purpose.

0:00:12.570,0:00:15.723
So, this number right over here.

0:00:16.600,0:00:18.090
What I wanna do is think

0:00:18.090,0:00:21.130
about how would I write this out in words?

0:00:21.130,0:00:22.970
And I encourage you to pause this video

0:00:22.970,0:00:24.720
and try to figure that out on your own

0:00:24.720,0:00:25.610
before we do it together.

0:00:25.610,0:00:28.110
And if you take out paper[br]and actually write this out,

0:00:28.110,0:00:29.823
how would you write this number?

0:00:31.080,0:00:33.150
Well now, we can do it together.

0:00:33.150,0:00:35.220
Actually before I even[br]write it out in words,

0:00:35.220,0:00:37.700
I'll write this out in a place value table

0:00:37.700,0:00:39.350
'cause it might help[br]us, or it just helps us

0:00:39.350,0:00:42.910
break down exactly what[br]this number represents.

0:00:42.910,0:00:45.310
So, just as a bit of a refresher,

0:00:45.310,0:00:47.960
if you're not familiar[br]with place value tables.

0:00:47.960,0:00:50.660
You think of a column for[br]the different place values

0:00:50.660,0:00:52.210
and here we're going from the ones place

0:00:52.210,0:00:55.390
all the way to 10s, 1,000s, 10,000s,

0:00:55.390,0:00:57.734
so we're going to have a 10,0000s

0:00:57.734,0:00:59.456
place right over here.

0:00:59.456,0:01:03.930
We're going to have a 1,000s[br]place right over here.

0:01:03.930,0:01:07.110
This is just an S here, so[br]ten thousands, one thousands.

0:01:07.110,0:01:08.760
Sometimes you'll see it written out.

0:01:08.760,0:01:12.045
This is the 100s place.

0:01:12.045,0:01:15.280
This is the 10s place.

0:01:15.280,0:01:17.650
And this is the ones place.

0:01:17.650,0:01:20.710
And so, how many 10,000s do we have?

0:01:20.710,0:01:22.300
Actually, let's start at the ones place.

0:01:22.300,0:01:23.580
How many ones do we have?

0:01:23.580,0:01:24.413
We see it right here.

0:01:24.413,0:01:26.720
We have five ones.

0:01:26.720,0:01:28.220
How many 10s do we have?

0:01:28.220,0:01:29.053
We see it right there,

0:01:29.053,0:01:31.610
actually, we have zero 10s.

0:01:31.610,0:01:34.280
How many 100s do we have?

0:01:34.280,0:01:36.930
We see it right there, six 100s.

0:01:36.930,0:01:38.610
How many 1,000s?

0:01:38.610,0:01:39.837
We go to the 1,000s place

0:01:39.837,0:01:42.160
and we see we have two 1,000s.

0:01:42.160,0:01:45.460
And then, how many 10,000s we have?

0:01:45.460,0:01:46.390
Well, we see right there,

0:01:46.390,0:01:48.510
we have eight 10,000s.

0:01:48.510,0:01:50.660
So now that we have this representation,

0:01:50.660,0:01:51.493
let's write it out in words

0:01:51.493,0:01:53.030
and you don't have to do this every time,

0:01:53.030,0:01:54.380
but I am just trying to make sure we see

0:01:54.380,0:01:57.200
every possible way of thinking about it.

0:01:57.200,0:01:59.698
So, you could say eight 10s,

0:01:59.698,0:02:04.140
two 1,000s, six 100s, and five ones,

0:02:04.140,0:02:07.260
but that's not exactly how[br]people would say it out in words.

0:02:07.260,0:02:09.180
What is typical is that people would say

0:02:09.180,0:02:14.040
82 1,000s, 600 and five.

0:02:14.040,0:02:15.790
And so I'm gonna write it that way.

0:02:15.790,0:02:17.490
And when you write it out in words,

0:02:17.490,0:02:19.900
the standard way of doing[br]it is actually put commas

0:02:19.900,0:02:22.000
wherever you put the commas in,

0:02:22.000,0:02:24.430
this is right over here[br]written in standard form.

0:02:24.430,0:02:27.240
So what we would do is,[br]we would express this part

0:02:27.240,0:02:30.310
right over here as eighty-two thousand,

0:02:30.310,0:02:31.850
so let me write it out.

0:02:31.850,0:02:33.537
Eighty two thousand.

0:02:42.330,0:02:45.400
And then, put this comma there.

0:02:45.400,0:02:47.260
Eighty two thousand, comma,

0:02:47.260,0:02:50.940
and then we have 600[br]and then we have no 10s,

0:02:50.940,0:02:52.430
so it's 605.

0:02:52.430,0:02:53.800
If there was a one 10 here,

0:02:53.800,0:02:55.100
then it would have been 615,

0:02:55.100,0:02:56.820
but this is just 605.

0:02:56.820,0:02:59.980
And so I will do it in a different color.

0:02:59.980,0:03:01.730
Let's do it in this blue color.

0:03:01.730,0:03:06.730
So eighty-two thousand,[br]and then six hundred five.

0:03:10.560,0:03:11.810
And we're done!

0:03:11.810,0:03:13.433
Let's do another example.

0:03:14.670,0:03:16.770
So now I'm gonna write[br]out a number in words

0:03:16.770,0:03:18.340
and I want you to write[br]it in standard form.

0:03:18.340,0:03:22.983
So, the number is fifty[br]thousand, six hundred thirty-one.

0:03:35.310,0:03:38.240
And I want you to write[br]this in standard form.

0:03:38.240,0:03:40.120
So it's really just[br]write it out as a number

0:03:40.120,0:03:41.810
and put commas in the appropriate places.

0:03:41.810,0:03:44.073
Pause this video and[br]see if you can do that.

0:03:44.980,0:03:47.190
All right, now let's do it together.

0:03:47.190,0:03:51.120
So, this first part, fifty thousand,

0:03:51.120,0:03:53.420
well, we could just write that as,

0:03:53.420,0:03:55.150
actually, let's put the[br]place values out here,

0:03:55.150,0:03:56.621
so there's a 10,000s place,

0:03:56.621,0:04:00.843
this is a 1,000s place,[br]100s, 10s, and ones.

0:04:00.843,0:04:02.493
So, fifty thousand, so 50 1,000s,

0:04:04.080,0:04:05.350
you could write like this,

0:04:05.350,0:04:07.430
you could say that's five 10,000s,

0:04:07.430,0:04:09.849
or you could say this is 50 1,000s.

0:04:09.849,0:04:13.830
Then they say six hundred thirty-one.

0:04:13.830,0:04:18.410
So, six hundred, well that's[br]six 100s right over here

0:04:18.410,0:04:23.220
and then thirty-one,[br]that is thirty and one,

0:04:23.220,0:04:25.700
or three 10s and one one,

0:04:25.700,0:04:28.930
three 10s and one one, or 31.

0:04:28.930,0:04:31.240
And of course, you wanna put your comma

0:04:31.240,0:04:33.840
in the same place, and you put your comma

0:04:33.840,0:04:36.360
every three places, so[br]the first time you do it,

0:04:36.360,0:04:37.860
if you're moving from the right,

0:04:37.860,0:04:42.180
you put it between the[br]100s and the 1,000s place.

0:04:42.180,0:04:43.013
So, there you have it.

0:04:43.013,0:04:47.623
This is the same thing as 50,631.

0:04:49.080,0:04:52.593
This is that number written in stand form.
