as the quiet rages....

I’m sitting here while my students are taking their midterm and I feel the tension in the room. I could cut it with a knife. For lack of something to do I’ve decided to watch them. Watching someone take a test is like watching them in a private moment. They are not connected to this class. They are not aware of their surroundings. This allows me to watch, to peek at them when they are unaware or unconcerned that others are watching. Their facial expressions and their every thought is displayed across their face. I can even tell when they are having a problem with a question….oh, there goes one right now. I see her confused expression….and there goes her hand. (Be right back) So back to my watching, it’s almost obscene the way I observe them. I can’t help it. I am intrigued by their thought process. Is it wrong to sit them down in front of me to “perform” in this way for my own observations? Of course not. They are gaining their education and I am gaining insight.

Perhaps I can predetermine grade ranges based on how they react to the test. Interesting…

Kid: (looking at a quadrilateral with equal sides....a square for anyone who missed that lesson in school...) "how can I find x?"

Me: Well, if all sides are equal and this side is 2x + 5 and this side is 4x - 3 then how can we make an equation to solve for x?

Kid: (blank stare)

Me: So if this side is EQUAL to this side how can I make an equation, which has something EQUAL to something else, so I can solve for x?

Kid: (blank stare)

Me: So let's just say this side was 2x (points to one side) and this side was 10 (points to consecutive side) how would I solve for x?

Kid: (blank stare) ......x is 5

Me: GREAT! Now how did you get x = 5?

Kid: (blank stare)

Me: Just try your best.....

zero?

I suppose you can break down -(infinity) + (infinity) to = 0, but then you run in to all sorts of complications. Like (infinity) is a limit. It is approaching something, which would certainly be an idea that doesn't relate to a typical, numerical value. However, if you go number by number: starting with 1 and add -1 and 1 and continue to (infinity) then I could certainly gain my original answer of 0.

Yeah, I know: this idea is either extremely simple or extremely boring, but I wanted to actually start this impromptu blog with the answer to it's title. The rest of the posts will just be funny or interesting anecdotes about being a math teacher. :D
