1
00:00:00,470 --> 00:00:01,660
- What we're going to do in this video

2
00:00:01,660 --> 00:00:04,800
is get some practice writing
reasonably large numbers

3
00:00:04,800 --> 00:00:06,850
in different ways.

4
00:00:06,850 --> 00:00:09,920
So, for example, let's
say we had this number

5
00:00:09,920 --> 00:00:12,570
and I'm going to not say
it out loud on purpose.

6
00:00:12,570 --> 00:00:15,723
So, this number right over here.

7
00:00:16,600 --> 00:00:18,090
What I wanna do is think

8
00:00:18,090 --> 00:00:21,130
about how would I write this out in words?

9
00:00:21,130 --> 00:00:22,970
And I encourage you to pause this video

10
00:00:22,970 --> 00:00:24,720
and try to figure that out on your own

11
00:00:24,720 --> 00:00:25,610
before we do it together.

12
00:00:25,610 --> 00:00:28,110
And if you take out paper
and actually write this out,

13
00:00:28,110 --> 00:00:29,823
how would you write this number?

14
00:00:31,080 --> 00:00:33,150
Well now, we can do it together.

15
00:00:33,150 --> 00:00:35,220
Actually before I even
write it out in words,

16
00:00:35,220 --> 00:00:37,700
I'll write this out in a place value table

17
00:00:37,700 --> 00:00:39,350
'cause it might help
us, or it just helps us

18
00:00:39,350 --> 00:00:42,910
break down exactly what
this number represents.

19
00:00:42,910 --> 00:00:45,310
So, just as a bit of a refresher,

20
00:00:45,310 --> 00:00:47,960
if you're not familiar
with place value tables.

21
00:00:47,960 --> 00:00:50,660
You think of a column for
the different place values

22
00:00:50,660 --> 00:00:52,210
and here we're going from the ones place

23
00:00:52,210 --> 00:00:55,390
all the way to 10s, 1,000s, 10,000s,

24
00:00:55,390 --> 00:00:57,734
so we're going to have a 10,0000s

25
00:00:57,734 --> 00:00:59,456
place right over here.

26
00:00:59,456 --> 00:01:03,930
We're going to have a 1,000s
place right over here.

27
00:01:03,930 --> 00:01:07,110
This is just an S here, so
ten thousands, one thousands.

28
00:01:07,110 --> 00:01:08,760
Sometimes you'll see it written out.

29
00:01:08,760 --> 00:01:12,045
This is the 100s place.

30
00:01:12,045 --> 00:01:15,280
This is the 10s place.

31
00:01:15,280 --> 00:01:17,650
And this is the ones place.

32
00:01:17,650 --> 00:01:20,710
And so, how many 10,000s do we have?

33
00:01:20,710 --> 00:01:22,300
Actually, let's start at the ones place.

34
00:01:22,300 --> 00:01:23,580
How many ones do we have?

35
00:01:23,580 --> 00:01:24,413
We see it right here.

36
00:01:24,413 --> 00:01:26,720
We have five ones.

37
00:01:26,720 --> 00:01:28,220
How many 10s do we have?

38
00:01:28,220 --> 00:01:29,053
We see it right there,

39
00:01:29,053 --> 00:01:31,610
actually, we have zero 10s.

40
00:01:31,610 --> 00:01:34,280
How many 100s do we have?

41
00:01:34,280 --> 00:01:36,930
We see it right there, six 100s.

42
00:01:36,930 --> 00:01:38,610
How many 1,000s?

43
00:01:38,610 --> 00:01:39,837
We go to the 1,000s place

44
00:01:39,837 --> 00:01:42,160
and we see we have two 1,000s.

45
00:01:42,160 --> 00:01:45,460
And then, how many 10,000s we have?

46
00:01:45,460 --> 00:01:46,390
Well, we see right there,

47
00:01:46,390 --> 00:01:48,510
we have eight 10,000s.

48
00:01:48,510 --> 00:01:50,660
So now that we have this representation,

49
00:01:50,660 --> 00:01:51,493
let's write it out in words

50
00:01:51,493 --> 00:01:53,030
and you don't have to do this every time,

51
00:01:53,030 --> 00:01:54,380
but I am just trying to make sure we see

52
00:01:54,380 --> 00:01:57,200
every possible way of thinking about it.

53
00:01:57,200 --> 00:01:59,698
So, you could say eight 10s,

54
00:01:59,698 --> 00:02:04,140
two 1,000s, six 100s, and five ones,

55
00:02:04,140 --> 00:02:07,260
but that's not exactly how
people would say it out in words.

56
00:02:07,260 --> 00:02:09,180
What is typical is that people would say

57
00:02:09,180 --> 00:02:14,040
82 1,000s, 600 and five.

58
00:02:14,040 --> 00:02:15,790
And so I'm gonna write it that way.

59
00:02:15,790 --> 00:02:17,490
And when you write it out in words,

60
00:02:17,490 --> 00:02:19,900
the standard way of doing
it is actually put commas

61
00:02:19,900 --> 00:02:22,000
wherever you put the commas in,

62
00:02:22,000 --> 00:02:24,430
this is right over here
written in standard form.

63
00:02:24,430 --> 00:02:27,240
So what we would do is,
we would express this part

64
00:02:27,240 --> 00:02:30,310
right over here as eighty-two thousand,

65
00:02:30,310 --> 00:02:31,850
so let me write it out.

66
00:02:31,850 --> 00:02:33,537
Eighty two thousand.

67
00:02:42,330 --> 00:02:45,400
And then, put this comma there.

68
00:02:45,400 --> 00:02:47,260
Eighty two thousand, comma,

69
00:02:47,260 --> 00:02:50,940
and then we have 600
and then we have no 10s,

70
00:02:50,940 --> 00:02:52,430
so it's 605.

71
00:02:52,430 --> 00:02:53,800
If there was a one 10 here,

72
00:02:53,800 --> 00:02:55,100
then it would have been 615,

73
00:02:55,100 --> 00:02:56,820
but this is just 605.

74
00:02:56,820 --> 00:02:59,980
And so I will do it in a different color.

75
00:02:59,980 --> 00:03:01,730
Let's do it in this blue color.

76
00:03:01,730 --> 00:03:06,730
So eighty-two thousand,
and then six hundred five.

77
00:03:10,560 --> 00:03:11,810
And we're done!

78
00:03:11,810 --> 00:03:13,433
Let's do another example.

79
00:03:14,670 --> 00:03:16,770
So now I'm gonna write
out a number in words

80
00:03:16,770 --> 00:03:18,340
and I want you to write
it in standard form.

81
00:03:18,340 --> 00:03:22,983
So, the number is fifty
thousand, six hundred thirty-one.

82
00:03:35,310 --> 00:03:38,240
And I want you to write
this in standard form.

83
00:03:38,240 --> 00:03:40,120
So it's really just
write it out as a number

84
00:03:40,120 --> 00:03:41,810
and put commas in the appropriate places.

85
00:03:41,810 --> 00:03:44,073
Pause this video and
see if you can do that.

86
00:03:44,980 --> 00:03:47,190
All right, now let's do it together.

87
00:03:47,190 --> 00:03:51,120
So, this first part, fifty thousand,

88
00:03:51,120 --> 00:03:53,420
well, we could just write that as,

89
00:03:53,420 --> 00:03:55,150
actually, let's put the
place values out here,

90
00:03:55,150 --> 00:03:56,621
so there's a 10,000s place,

91
00:03:56,621 --> 00:04:00,843
this is a 1,000s place,
100s, 10s, and ones.

92
00:04:00,843 --> 00:04:02,493
So, fifty thousand, so 50 1,000s,

93
00:04:04,080 --> 00:04:05,350
you could write like this,

94
00:04:05,350 --> 00:04:07,430
you could say that's five 10,000s,

95
00:04:07,430 --> 00:04:09,849
or you could say this is 50 1,000s.

96
00:04:09,849 --> 00:04:13,830
Then they say six hundred thirty-one.

97
00:04:13,830 --> 00:04:18,410
So, six hundred, well that's
six 100s right over here

98
00:04:18,410 --> 00:04:23,220
and then thirty-one,
that is thirty and one,

99
00:04:23,220 --> 00:04:25,700
or three 10s and one one,

100
00:04:25,700 --> 00:04:28,930
three 10s and one one, or 31.

101
00:04:28,930 --> 00:04:31,240
And of course, you wanna put your comma

102
00:04:31,240 --> 00:04:33,840
in the same place, and you put your comma

103
00:04:33,840 --> 00:04:36,360
every three places, so
the first time you do it,

104
00:04:36,360 --> 00:04:37,860
if you're moving from the right,

105
00:04:37,860 --> 00:04:42,180
you put it between the
100s and the 1,000s place.

106
00:04:42,180 --> 00:04:43,013
So, there you have it.

107
00:04:43,013 --> 00:04:47,623
This is the same thing as 50,631.

108
00:04:49,080 --> 00:04:52,593
This is that number written in stand form.
