Yeah, we're, well, you can just use the pen and mark the point on the pin on the number line.
10,538
23
[]
student
What
10,538
24
[]
volunteer
There's a pen tool
10,538
25
[]
volunteer
it's
10,538
26
[]
volunteer
uh
10,538
27
[]
volunteer
right around here. Looks like a pen or a pencil.
10,538
28
[]
student
You would plot it uh
10,538
29
[]
student
right.
10,538
30
[]
student
Oh I
10,538
31
[]
volunteer
Yeah, yeah. You use the eraser, but that's
10,538
32
[]
student
Yeah, right here.
10,538
33
[]
volunteer
that's it. OK.
10,538
34
[]
volunteer
So
10,538
35
[]
volunteer
what is the decimal for 1. 1.5.
10,538
36
[]
student
1.5.
10,538
37
[]
volunteer
Right.
10,538
38
[]
volunteer
So if they said plot 1.5 on the number line, that's where you applaud it.
10,538
39
[]
student
OK
10,538
40
[]
volunteer
And it's always going to be guessing unless they have the
10,538
41
[]
volunteer
the decimal points marked on the line.
10,538
42
[]
volunteer
But like if they said 2.1.
10,538
43
[]
volunteer
then
10,538
44
[]
volunteer
you might say it's about here.
10,538
45
[]
volunteer
and 3.9 might be around here like that.
10,538
46
[]
student
OK
10,538
47
[]
volunteer
So you, um
10,538
48
[]
volunteer
you said you kind of understand decimals
10,538
49
[]
student
Yeah
10,538
50
[]
student
Can you also work on uh negatives.
10,538
51
[]
volunteer
on negatives
10,538
52
[]
student
Yeah, negative decimals.
10,538
53
[]
volunteer
When negative decimals are
10,538
54
[]
volunteer
gonna be, let me move all of this a little bit.
10,538
55
[]
volunteer
and extend the number line.
10,538
56
[]
student
Yes
10,538
57
[]
volunteer
so we need a 0.
10,538
58
[]
volunteer
OK
10,538
59
[]
volunteer
Now, let's see
10,538
60
[]
volunteer
So the negatives
10,538
61
[]
volunteer
are going
10,538
62
[]
volunteer
down from 0, right
10,538
63
[]
student
Yeah
10,538
64
[]
volunteer
So
10,538
65
[]
volunteer
like
10,538
66
[]
volunteer
uh, OK.
10,538
67
[]
student
Yeah
10,538
68
[]
volunteer
writing.
10,538
69
[]
volunteer
1/2.
10,538
70
[]
student
Mhm
10,538
71
[]
volunteer
Now that would be minus 1/2 and
10,538
72
[]
volunteer
down on the
10,538
73
[]
volunteer
2 and 3 would be minus 2.5.
10,538
74
[]
volunteer
because it's halfway between -2 and -3.
10,538
75
[]
volunteer
or decimals, the same as decimals. So it'd be minus 2.5 minus 1.5
10,538
76
[]
volunteer
and so on
10,538
77
[]
volunteer
because the larger the when it's negative
10,538
78
[]
volunteer
the, the numbers that look larger are smaller, right?
10,538
79
[]
student
Yeah
10,538
80
[]
volunteer
So
10,538
81
[]
volunteer
minus 2.5 1.5
10,538
82
[]
volunteer
minus 0.5.
10,538
83
[]
student
Mm
10,538
84
[]
volunteer
So it looks something like that
10,538
85
[]
student
Uh, can you give me one second? I need to go get my headphones.
10,538
86
[]
volunteer
Sure.
10,538
87
[]
student
OK
10,538
88
[]
volunteer
right
10,538
89
[]
volunteer
So does this all make sense?
10,538
90
[]
student
Yeah
10,538
91
[]
volunteer
OK
10,538
92
[]
volunteer
Let's see. What else you
10,538
93
[]
volunteer
uh,
10,538
94
[]
volunteer
you said negative numbers, fractions and percents, oh.
10,538
95
[]
student
Yeah
10,538
96
[]
volunteer
So if you take a percent is just a way of
10,538
97
[]
volunteer
talking about any number.
10,538
98
[]
volunteer
It's not something different.
10,538
99
[]
volunteer
and
10,538
100
[]
volunteer
a percent is 0.01 times whatever number you're talking about.
10,538
101
[]
student
Mhm
10,538
102
[]
volunteer
So if our number is
10,538
103
[]
volunteer
1
10,538
104
[]
volunteer
then that makes 100%.
10,538
105
[]
volunteer
and 0.1
10,538
106
[]
student
OK
10,538
107
[]
volunteer
is gonna be what, that's 100 times 0.1.
10,538
108
[]
student
0, 1%
10,538
109
[]
volunteer
Well, at
10,538
110
[]
volunteer
0.1 means a 10th, right?
10,538
111
[]
student
Wait
10,538
112
[]
student
10%
10,538
113
[]
volunteer
Right.
10,538
114
[]
volunteer
So whatever you have on, like, if you had 0.01, that means 1% because you have to multiply it by 100.
10,538
115
[]
student
Mhm
10,538
116
[]
volunteer
And that's uh
10,538
117
[]
volunteer
OK
10,538
118
[]
volunteer
So if you had, if, if you divided say
10,538
119
[]
volunteer
1/3
10,538
120
[]
volunteer
you get 0.3333.
10,538
121
[]
