11
00:00:01,406 --> 00:00:05,594
A lot, a lot of just kindof

2
00:00:05,594 --> 00:00:07,027
giving up on the idea

3
00:00:07,027 --> 00:00:09,406
of tracking everything all at once,

4
00:00:09,406 --> 00:00:11,000
I'm just getting points. 

5
00:00:11,000 --> 00:00:12,718
So a lot of people

6
00:00:12,718 --> 00:00:15,669
that fell into that... I don't know, comfort zone, almost

7
00:00:15,669 --> 00:00:18,435
of just going step by step

8
00:00:18,435 --> 00:00:21,231
and plotting step by step the points. 

9
00:00:21,231 --> 00:00:23,533
Okay, I didn't see as much of this

10
00:00:23,533 --> 00:00:24,530
as I would like.

11
00:00:24,530 --> 00:00:26,686
So everybody, for me, right now

12
00:00:26,686 --> 00:00:28,138
we're going to do this together,

13
00:00:28,138 --> 00:00:30,442
to make sure we're all thinking about it 

14
00:00:30,442 --> 00:00:32,389
the way that we want you to think about it. 

15
00:00:32,389 --> 00:00:34,420
and don't do it on your paper, do it in the air. 

16
00:00:34,420 --> 00:00:36,655
That way I can watch you and see what you are doing. OK?

17
00:00:36,655 --> 00:00:39,572
And by the way, we are on

18
00:00:39,572 --> 00:00:41,290
activity two right now. 

19
00:00:41,290 --> 00:00:44,060
So we are tracking distance from start

20
00:00:44,060 --> 00:00:46,747
So, we're students and it says track the timer along

21
00:00:46,747 --> 00:00:49,155
the horizontal axis using your right index finger. 

22
00:00:49,155 --> 00:00:50,780
So that is all you're gonna do. 

23
00:00:50,780 --> 00:00:52,848
All I want you to do right now 

24
00:00:52,848 --> 00:00:55,811
is using your right index finger, you're going to track

25
00:00:55,811 --> 00:00:59,389
time and time alone. 

26
00:00:59,389 --> 00:01:00,561
You with me?

27
00:01:00,561 --> 00:01:03,874
Time and time alone. 

28
00:01:03,874 --> 00:01:06,656
Ready? Fingers in the air!

29
00:01:06,656 --> 00:01:09,349
Track time and time alone. You're mark, set 

30
00:01:09,349 --> 00:01:12,248
Danielle? [oh, sorry] You're mark set

31
00:01:12,248 --> 00:01:13,655
time and time alone, go!

32
00:01:18,263 --> 00:01:20,936
 Just time Brianna.

33
00:01:24,450 --> 00:01:26,530
My arm's all over here.

34
00:01:26,530 --> 00:01:29,325
Okay, so the time is which way?

35
00:01:29,325 --> 00:01:30,591
Horizontal or vertical axis?

36
00:01:30,591 --> 00:01:32,165
[vertical][Horizontal]

37
00:01:32,165 --> 00:01:35,072
Horizontal, horizontal! It's this one.

38
00:01:35,072 --> 00:01:37,170
OK, so your time finger did what?

39
00:01:37,170 --> 00:01:38,451
[It just went like this.]

40
00:01:38,451 --> 00:01:39,545
It just went like this.

41
00:01:39,545 --> 00:01:41,591
You just track the time, and that's it. 

42
00:01:41,591 --> 00:01:44,233
That is not a very hard one to do, perhaps. 

43
00:01:44,233 --> 00:01:47,280
Now forget that one, bust out your distance finger. 

44
00:01:47,280 --> 00:01:50,216
OK, your distance finger goes which way?

45
00:01:50,216 --> 00:01:52,030
[Up and down] Up and down. 

46
00:01:52,030 --> 00:01:53,858
If your finger goes up that means...

47
00:01:53,858 --> 00:01:55,670
[It's increasing?]

48
00:01:55,670 --> 00:01:57,316
The distance is increasing from where?

49
00:01:57,316 --> 00:01:59,051
[From the start] From the start.

50
00:01:59,051 --> 00:02:01,826
If your finger goes down, that means...

51
00:02:01,826 --> 00:02:05,466
decreasing or... Katie?

52
00:02:05,466 --> 00:02:07,388
[Getting closer] Getting closer to the start. 

53
00:02:07,388 --> 00:02:09,748
So forget time, bust out distance finger. 

54
00:02:09,748 --> 00:02:12,061
All you're moving is distance, up and down. 

55
00:02:12,061 --> 00:02:13,780
Mark, set, go!

56
00:02:20,498 --> 00:02:23,393
Whoa, okay, I saw fingers get confused. 

57
00:02:28,498 --> 00:02:32,419
Okay, ready. We're tracking distance from... [start] start. 

58
00:02:32,419 --> 00:02:34,155
Greg, you with us? [yeah]

59
00:02:34,155 --> 00:02:38,311
Okay just again distance finger. Mark, set, go!

60
00:02:50,014 --> 00:02:52,998
Okay. Gromick what did you do?

61
00:02:52,998 --> 00:02:55,169
[I kept going up] Why did you keep going up?

62
00:02:55,169 --> 00:02:57,733
[I wasn't paying attention] What should you have done?

63
00:02:57,733 --> 00:03:00,549
[Went down] Why? [Because he went back to the start.]

64
00:03:00,549 --> 00:03:02,061
Because he went back to the start. 

65
00:03:02,061 --> 00:03:04,014
Okay, so now you have this sense of...

66
00:03:04,014 --> 00:03:05,450
He's walking away, going back,

67
00:03:05,450 --> 00:03:07,217
walking away, coming back, right?

68
00:03:07,764 --> 00:03:11,264
But he is doing all of this over the course of time. 

69
00:03:11,264 --> 00:03:12,748
So guess what?

70
00:03:12,748 --> 00:03:15,358
We bust out both fingers. 

71
00:03:15,358 --> 00:03:18,108
OK, you're tracking distance

72
00:03:18,108 --> 00:03:20,092
You're tracking time.

73
00:03:20,092 --> 00:03:22,951
At the same time, both things are happening.

74
00:03:22,951 --> 00:03:25,044
Ready? Mark, set, go!

75
00:03:29,342 --> 00:03:32,655
[Oops, I went to fast]

76
00:03:32,655 --> 00:03:35,811
[I'm going the wrong way]

77
00:03:38,155 --> 00:03:40,076
OK, let's try that again. 

78
00:03:40,076 --> 00:03:42,436
One more time on that one. 

79
00:03:42,436 --> 00:03:43,747
No we're just separate right now. 

80
00:03:43,747 --> 00:03:45,587
This one's staying like this, this one stay like this.

81
00:03:45,587 --> 00:03:46,593
Don't worry about the over

82
00:03:46,593 --> 00:03:49,061
[Oh!] Yeah, just like this. 

83
00:03:49,061 --> 00:03:52,998
That's the next step. Just track distance

84
00:03:52,998 --> 00:03:56,026
And just track time. Don't worry about 

85
00:03:56,026 --> 00:03:57,092
The whole keeping it 

86
00:03:57,092 --> 00:03:58,717
over each other yet. 

87
00:03:58,717 --> 00:04:00,631
For now just try to get them both going at once.

88
00:04:00,631 --> 00:04:01,959
At little coordination here. 

89
00:04:01,959 --> 00:04:03,764
Ready? Mark, set, go!

90
00:04:12,461 --> 00:04:14,514
[Oh, I'm doing it wrong!] What did you do?

91
00:04:14,514 --> 00:04:17,394
[I didn't go up and down] And what were you suppose to?

92
00:04:17,394 --> 00:04:19,846
[Because you come back] Okay. 

93
00:04:19,846 --> 00:04:23,464
So you have a li-... you're-you know, you're getting better at this. 

94
00:04:23,464 --> 00:04:24,589
But now I'm going to make it harder. 

95
00:04:24,589 --> 00:04:25,795
Keep it over each other this time. 

96
00:04:25,795 --> 00:04:28,459
So as time goes by

97
00:04:28,459 --> 00:04:30,552
and your distance is doing whatever it's doing

98
00:04:30,552 --> 00:04:33,076
keep it above. 

99
00:04:33,076 --> 00:04:35,295
Okay? Keep it above. 

100
00:04:35,295 --> 00:04:38,889
Ready? Mark, set ,go!

101
00:04:46,586 --> 00:04:47,774
Guys!

102
00:04:51,201 --> 00:04:55,076
Okay, ready? Take your distance finger

103
00:04:55,076 --> 00:04:57,716
Dip it in the upper left hand corner of your desk.

104
00:04:57,716 --> 00:05:01,795
You now officially have dust all over your finger.

105
00:05:01,795 --> 00:05:04,874
You are- You are Tinkerbell right now. 

106
00:05:04,874 --> 00:05:08,218
OK? So every time that distance finger moves

107
00:05:08,218 --> 00:05:09,685
what do you leave behind?

108
00:05:09,685 --> 00:05:12,014
[pixie dust] A piece of pixie dust.

109
00:05:12,014 --> 00:05:13,107
So do it again.

110
00:05:13,107 --> 00:05:16,591
Only this time, imagine the trail you've left behind. 

111
00:05:16,591 --> 00:05:17,262
Ready?

112
00:05:18,413 --> 00:05:19,685
Mark, set, go!

113
00:05:31,122 --> 00:05:33,654
Now I want you to look at the graphs you created on your paper. 

114
00:05:35,100 --> 00:05:38,045
Does it look like your pixie dust you left behind? [course]

115
00:05:38,045 --> 00:05:40,295
Okay. But here is the difference

116
00:05:40,295 --> 00:05:43,502
if your graph, if your graph on paper

117
00:05:43,502 --> 00:05:45,889
has four points on it,

118
00:05:45,889 --> 00:05:47,310
ten points on it,

119
00:05:47,310 --> 00:05:49,139
are there really only four points?

120
00:05:49,139 --> 00:05:51,608
Are there really only ten points?

121
00:05:51,608 --> 00:05:53,233
[No] How many points are there?

122
00:05:53,233 --> 00:05:56,374
[A lot] Crap-load. You really want to count them?
