A teacher gives a classroom lesson, interacting with a projected double who appears on the board, then surprises students with a water bottle and Halloween candy.
0:00 Now, what's gonna happen if I step into here? 0:07 You can see me, but I can't see you very well. Let me see what happens if I step over here. 0:16 First of all, as a reminder that the paper's due October 31st at desk. 0:21 Let me erase this so I can show you. Oh, this is the wrong eraser. 0:25 This is the whiteboard eraser. Well, I don't need this. 0:34 Okay, so let's see what would happen if we start with this equation right here. 0:44 We would all agree that 1 equals 1, 0:50 or 1 equals 2. Hm, something stream- seems strange there, because that's not possible, right? 0:56 It's not possible for 1 to equal 2, otherwise there are 1 of me, and it could be, that would be the same as saying there are 2 of me. 1:07 Who are you? Who am I? Well, 1 equals 2, I have just as much of the right to exist as you do. 1:13 I, I can only think of one way to get rid of this. Let's see what happens if I erase this. 1:18 Wait, no, stop. 1:26 Oh, okay, good. Well, I'm done with this one. 1:32 Oh, I forgot. I was going to ask, does anybody have any questions about the homework? 1:38 Yeah, I do. When is the chapter 15 homework due? 1:42 Yeah, good question. 1:44 It's going to be due on Monday, so be sure and bring it to class on Monday. 1:48 So, okay. 1:53 Oh, look. I don't know what this is for. This is a water bottle. 1:57 I wonder if it works. 2:09 Whoa, what is that? Whoa, he's done. 2:13 Look around. 2:18 Seems okay. 2:23 Finally, I have a little quiz for you, just a little geometry problem here. 2:28 What I have put on the board here are two figures. I want to see if you guys can tell the difference, if they're congruent or not. 2:35 So look carefully at these 2 different triangles, and tell me if you see any difference at all between those 2 figures. 2:41 Look very closely. 2:58 And you found part of your 3:06 Okay, well, sorry for stealing. Halloween season after all, and oh, speaking of which, look, I found some candies. 3:13 Here, I'll give some to you guys. 3:20 I dropped one down here. 3:23 I found it. 3:30 With my, uh, video camera, I guess. Last, last day. 3:41 What are you doing here? 3:43 Nothing, I- nothing. I wasn't trying to do anything. 3:46 Go on, get out of here, get out. 3:47 Yeah, sorry.
