Finality!

Well, I gave my first two exams today: the Algebra I exam, and the Prealgebra exam. The results aren't in yet, I am about half done grading the first one right now.

Since I know that all of you out there are still using the Algebra that you learned in Algebra I, I would like to post 4 questions on this blog.

Post your answers in the comments. (If anyone can get all 4 of them right, maybe I will put an extra point on every Algebra exam... or something like that. Am I allowed to do that? Of course I am! I am the teacher! Ha, ha ha! Hmm... maybe if nobody can get all 4 of them right, I will take off points... Oh yeah! ...Wait a minute, hold those phones kiddies, I am just joking!)

Here they are:

1. Simplify this expression.



2. Solve this absolute value inequality.



3. Solve this system of linear equations.



4. Solve this quadratic equation.

    ok, here we go. i better get these right. or i will feel very stupid.

    1. y9/27x3
    [y to the 9th over 27 times x cubed]

    2. -9 greaterthanorequalto x greaterthanorequalto -1

    3. (-2,3)

    4. This is the one that I can't figure out....!?!
    -1 plus/minus squarerootof 65 all over 2

    or... 3.53 or -4.53

    I'm sure that's wrong, but I just finished my Chem2 final, you can't expect too much outta me.

    I'll give a try (my trig final is done).

    1) y to 9th power over 9 times x to the 3rd power

    2) x is greater or equal to -1 and less then or = 9

    3) x=-2, y=3

    4) -5 + or - radical 65 over ten. (and i don't know what that is simplified).

    The weird thing about math, is that it's rather relaxing. I can't cram one more spanish word or english poet into my head, but math is just like solving a puzzle. Its taking a bunch of random pieces and fitting them all together to make one simple equation!

    Matt,
    I can't do it. I don't know how to put thoswe expressions in the Google calculator. Besides, I majored in Psychology. We don't need no stinkin algebra in psychology; well, at least I don't. :-)

    Well, I think that Tirzah got it right. I will have to double check my answers, but I think that Stephanie made the "commom error" on the last one.

    I'm feeling very, very old right now. Can it possibly be decades since I even looked at such things???

The Seed and The Soil of Education (New Learning Project Part 1)

(This is my entry for the first part of my project for my New Learning course that I am taking.) Introduction Corn Fields in Illinois I have lived the majority of my life in the Midwest: mid-state Illinois to be specific. Where I live, farming is everywhere. My grandparents and great-grandparents on both sides of my family were farmers. My dad grew up on a farm and owned farmland, well into my own adulthood. But, even if it wasn’t in the family, I still would have been surrounded by farming. You can’t go more than a mile outside of my city’s limits without encountering miles and miles of fields. Most of our highways, and even interstates, are located between acres of farmland.

This too shall pass...

Gam zeh ya'avor (Hebrew) "This Too Shall Pass" Welcome!  According to Google Analytics, this is by far the most visited post that I have ever written.  If someone comes here from a search engine, most of the time they are looking for " this too shall pass quote " or simply " this too shall pass " on Google or one of the other search engines. I am sure that most of the time visitors are looking for the originations of this quote, but I have to wonder, why is this quote on people's minds? Why are they pondering the passing of events?   Here is my thought: It is probably because most of us have realized that the adult life is much harder than we ever imagined it to be. There is more pain and more sorrow than we had ever imagined as children, but we have learned that time keeps ticking. And as time continues to flow things pass. In fact, even the really big things and the really hard things will still pass. If you are here because you are thinking ...

The Minnesota Crime Commission wrote:

Every baby starts life as a little savage. He is completely selfish and self-centered. He wants what he wants when he wants it: his bottle, his mother's attention, his playmate's toys, his uncle's watch, or whatever. Deny him these and he seethes with rage and aggressiveness which would be murderous were he not so helpless. He's dirty, he has no morals, no knowledge, no developed skills. This means that all children, not just certain children but all children, are born delinquent. If permitted to continue in their self-centered world of infancy, given free reign to their impulsive actions to satisfy each want, every child would grow up a criminal, a thief, a killer, a rapist.
