hi

student
Hello
17,904
2
[]
student
question
17,904
3
[]
student
right now
17,904
4
[]
volunteer
do that
17,904
5
[]
student
I need help comparing real numbers
17,904
6
[]
volunteer
ok great!
17,904
7
[]
student
Can you hear me when I talk?
17,904
8
[]
volunteer
yes sorry
17,904
9
[]
student
How do I show you what problems I NEED HELP WITH?
17,904
10
[]
student
do I draw it?
17,904
11
[]
volunteer
you can draw it on the whiteboard type it in the chat or screenshot it and but the screenshot on the whiteboard
17,904
12
[]
volunteer
this is a fun problem
17,904
13
[]
volunteer
the best way to do it would be to estimate squaroot 13
17,904
14
[]
student
Be it up with it right now.
17,904
15
[]
student
Yeah
17,904
16
[]
student
Did you do that?
17,904
17
[]
volunteer
so root 9 is 3 and root 16 is 4
17,904
18
[]
student
I don't know how to estimate the square root
17,904
19
[]
volunteer
so it is somewhere between 3 and 4
17,904
20
[]
student
OK
17,904
21
[]
student
between the
17,904
22
[]
student
16 is 4
17,904
23
[]
student
times 3 times
17,904
24
[]
student
3
17,904
25
[]
volunteer
pi is 3.14 so it is also between 3 and 4
17,904
26
[]
volunteer
we can manually square 3.14 and see if the result is bigger or smaller than 13
17,904
27
[]
volunteer
so find 3.14 times 3.14
17,904
28
[]
student
I don't understand how to do the first part
17,904
29
[]
volunteer
oh ok we are just finding between which integers the squareroot of 13
17,904
30
[]
volunteer
so we know that the sqaroot of 9 is 3
17,904
31
[]
volunteer
and the squareroot of 16 is 4
17,904
32
[]
volunteer
because 13 is between 9 and 16
17,904
33
[]
student
This is too confusing
17,904
34
[]
volunteer
we know that the squareroot of 13 is between 3 and 4
17,904
35
[]
student
You know the square root of 9 and 16 but I don't
17,904
36
[]
volunteer
oh, ok
17,904
37
[]
volunteer
so the square root of something means what times itself is that something
17,904
38
[]
volunteer
3 times 3 is what?
17,904
39
[]
student
9
17,904
40
[]
volunteer
therefore the squareroot of 9 is 3
17,904
41
[]
volunteer
because 3 times 3 is nine
17,904
42
[]
volunteer
so try and guess what the square root of 4 is
17,904
43
[]
student
2
17,904
44
[]
volunteer
good!
17,904
45
[]
volunteer
and guess what squareroot 16 is
17,904
46
[]
student
4
17,904
47
[]
volunteer
good, look at the board
17,904
48
[]
student
there isn't anything on the board
17,904
49
[]
volunteer
try scrolling down
17,904
50
[]
student
thanks
17,904
51
[]
volunteer
does this diagram makes sense
17,904
52
[]
student
so its like inbetween
17,904
53
[]
volunteer
exactly
17,904
54
[]
volunteer
and brobably about 3.5
17,904
55
[]
student
so would my answer be greater than, lesss than or equal
17,904
56
[]
student
?
17,904
57
[]
volunteer
because it is halfway between 9 and 16
17,904
58
[]
volunteer
well you tell me
17,904
59
[]
volunteer
is 3.5 greater than less than or equal to 3.14
17,904
60
[]
student
then I think it's greater than
17,904
61
[]
volunteer
Yep!
17,904
62
[]
student
this is the next one
17,904
63
[]
student
I think I need to change the % to a number or decimal but I don't know how
17,904
64
[]
volunteer
percent is super easy to change to a decimal, 25% equals .25
17,904
65
[]
volunteer
1% equals .01
17,904
66
[]
volunteer
100% equals 1
17,904
67
[]
volunteer
good!
17,904
68
[]
volunteer
now do long division to find 4/7
17,904
69
[]
student
so move it over two places
17,904
70
[]
volunteer
yeah, .55 is correct
17,904
71
[]
student
so it is equal?
17,904
72
[]
volunteer
no
17,904
73
[]
volunteer
you did the division wrong
17,904
74
[]
student
I will try again
17,904
75
[]
student
do I stop now?
17,904
76
[]
volunteer
yeah
17,904
77
[]
student
how do you know when to stop?
17,904
78
[]
volunteer
when you have enough digits to tell which one is bigger
17,904
79
[]
volunteer
so now you know that .55 is less than .57
17,904
80
[]
student
ohh
17,904
81
[]
student
So 0.57
17,904
82
[]
student
is bigger
17,904
83
[]
student
?
17,904
84
[]
volunteer
umm, yeah
17,904
85
[]
volunteer
its the same of 55 and 57
17,904
86
[]
volunteer
of which 57 is bigger
17,904
87
[]
student
ok
17,904
88
[]
student
Give me a second
17,904
89
[]
student
to get the next problem
17,904
90

student
Maya!!

[ { "pii_type": "PERSON", "surrogate": "Maya", "start": 0, "end": 4 } ]
volunteer
Hi Olivia
17,910
0
[ { "pii_type": "PERSON", "surrogate": "Olivia", "start": 3, "end": 9 } ]
student
Hi can you check my answer to this problem?
17,910
1
[]
volunteer
OK.
17,910
2
[]
volunteer
I'm reading...
17,910
3
[]
volunteer
Checking your result...
17,910
4
[]
volunteer
Your result is correct, but you can simplify it.
17,910
5
[]
student
?
17,910
6
[]
volunteer
You can divide top and bottom by 3.
