The Great Big Book of Algebra
Chapter One: Math Poems
Adding Integers (Haiku)
Adding Integers
when you add your integers
think about money.
Subtracting Integers (Haiku)
Subtract integers
Just remember that you must
add the opposite.
Partitive Division (Cinquain)
Partitive division
easy, simple
partitioning, grouping, sharing
sharing numbers evenly
partitioning.
Quotative Division (Free Verse)
Quotative division is easy to do,
for example the numbers six and two,
How many times does two go into six?
The answer is three (its as easy as cake-mix).
Make six into two equal groups,
If you said the answer is two, (oops)
The right answer is actually three
Now get it right, or you'll get stung by a bee.
Chapter two
Mr. Guy: Oh my, you look like a really sad clown. What's wrong?
Mr. Clown: Well you see, I was walking home from clown school and these two kids were laughing. They called me all sorts of things, but the one that got me the most is when they called me dumb. They told me that I couldn't do algebra!
Mr Guy: Mr. Clown, don't feel sad. Kids used to say that to me too, but when i grew up I became a teacher. That showed them!
Mr Clown: If you're a teacher, would you mind helping me slove these two algebra questions?
Mr. Guy: Of course I will, Mr. Clown. What are the two questions?
Mr. Clown: The first one is n+3-5n+12.
Mr. Guy: Easy peasy! The answer to that is -6n+15.
Mr Clown: Oh, but how do you know? What were the steps?
Mr. Guy:Well first of all, I did my grouping. That is when you combine like terms. For this equation, the like terms were -5n+n. Always remember that an "n" by itself always equals 1. So in this case, the answer to combining those like terms is -6n.
Mr. Clown: Hm, I get it! Well, sort of. Go on, Mr. Guy.
Mr. Guy: The same goes for the second part. We must combine like terms again. in the second part of the question, we are adding the numbers with no letter signs. That means we are adding +3+12. The answer to that is +15. That's how we get -6+n+15. Simple right?
Mr. Clown: Yes! I get it! But I don't think that my second question will not be as easy! It has brackets.
Mr. Guy: Don't worry. What's the question?
Mr. Clown: This question is 2+4(3n+8). Not as easy, huh?
Mr. Guy: Well easy enough! The answer is 12n+10!
Mr. Clown: Oh no, Mr. Guy. That doesn't look right. I think you're supposed to multiply 4 and 8, not add 8 and 2. It just doesn't look right the way you're doing it.
Mr. Guy:I thought you didn't know how to do algebra?
Mr. Clown: What? OH, i guess i just remembered from my years in normal school.
Mr. Guy:Well, Mr. Clown. The answer is 12n+34. You did good, now put a smile on your face!
Mr. Clown: Thanks , Mr. Guy! But about the smile part. I dont think i could do that, because this is the way my face is painted!

Today in class we answered the home work from last week and we also worked on our barn doors quadrant four.
Then we had to decide if either it was a partitive division, Quotitive division or neither. Mr.Harbeck told us that if you picked Quotitive you would go to the left side of the room , If you picked partitive you would have to go to the rigth side of the room, then for the people that picked neither was at the back and for the people that didn't know went to the front of the room . Well most of the people were at the back of the room because it was neither . And in the end of the discussion all of us where convinced to go to the back of the room because you cant share a negative numbers and you cant share a negative group. And all you can do is the multiplicative inverse.
The home work for today was page 7 , from 10-17 . The next scribe is GIAN !!

Scribe Post for October 29
Today in class, we learned about subtracting integers. In the beginning of class, Mr. H. talked about asking questions and not being shy. Then, he took a nap and gave us two integer questions to do with a partner, then some people went up to the smart board to solve the questions. Those questions were:
(+2) - (+6) + (-2) = ?
(+2) + (-6) + (-2) = -6
(-2) - (+5) + (-4) = ?
(-2) + (-5) + (-4) = -11
When we finished solving those questions, he gave us homework to do. Our homework is pages 48 and 49. For page 48, we have to do questions 21, 22, 23, 27, 29, 30, 37, 38, 39, 40. For page 49 we have to do questions 9, 10, 11, 14, 15, 25, 26. Here are two questions from page 48.
21. (-10) + (-8) - (-6) - (+2) =
(-10) + (-8) + (+6) + (-2) = -14
23. (+2) - (+6) + (-5) - (-9) =
(+2) + (-6) + (-5) + (+9)= 0
If there was a subtraction part, you have to change it to an addition statement then add the opposite.
(+2) - (+6) + (-2) = ?

(-2) - (+5) + (-4) = ?

Jessalyne's Integer Story
The Integer Genie
Once upon a time there was a little boy named Chris, and he was sleeping. Once he woke up he saw that he fell asleep without doing his homework. He didn't know what to do so he paced the floor nervously. Chris knew he couldn't stay home because his parents were going to be at work, and he didn't want to stay home. Chris knew that there was no time to spare. He got ready quickly, skipping his morning shower. He thought that with at least a little bit of time, he could get some homework done. Chris was sitting in the living room, trying to get some work done. It was no use. This work required some time, and Chris only had 30 minutes until he had to head off for school. Out of nowhere, a magic genie appeared.
"Solve this integer problem and I will have your homework done in a second!" The genie offered. Chris looked at the problem, and right away he knew what to do. Algebra tiles was the first thing that came into his mind.
"Yes! That's right!" Exclaimed the genie. "Your homework is now complete!" Chris jumped for joy at that thought. Now he could enjoy his breakfast. Later on, he was on his way to school when he spotted a small kitten stuck in a tree. He didn't know what to do. He had to get to school, but he knew he couldn't just leave when a kitten was stuck in a tree. Suddenly, the same genie appeared again.
"Solve this second integer problem, and I'll guarantee that this cat will be free from this tall tree." The genie said.
"I'll use a number line this time!" cheered Chris.
"That's right again!" The genie said cheerfully. With a blink of an eye, the kitten was falling to the ground, gently and safely. Chris cheered. He could make it on his way to school.
The day was going by smoothly. Chris was very happy.. that is, until he remembered that there was a new comic out of his favourite series, but the line started at 1:00pm and there was only 20 copies. Many of his friends said that they got their parents to line up for it, but Chris couldn't since his parents where at work. Then, you guessed it. The integer genie appeared yet again with another puzzle.
"Solve this one, and I'll have the comic appear right in front of your eyes." Chris was overjoyed.
"I need this comic so bad! I'll use have and owe."
"Good job, Chris! That's right again." The comic appeared right on Chris' desk. He jumped for joy! All of his friends wondered how he got it without even lining up. Chris just told them it was magic.
Soon enough, it was time to go home. Chris peered out the window, and it was raining hard. He had to walk 4 and a half blocks to get home, but he didn't want to if there was rain. He was waiting for the integer genie. Then, BAM. The genie appeared.
"Solve this, and you'll find yourself inside your house." Chris was so happy, and he decided to use mental math for this.
"I know the right answer for that!" Exclaimed Chris. "The right answer is...-1!"
"That's right!" Said the genie. "Now, go home!" And Chris was safe and sound in his own home.

Jessalyne's Measures of Central Tendency
Mean:
The mean is the average number in a set of data. To get the mean, you have to add up all the numbers in a set of data, then divide it the sum by how many numbers there are.
Median:The median is the middle number in a set of data. To get the median, you have to arrange the data in ascending order, then cross out the numbers two by two, starting each end, going inwards until you get to the middle number.
If there is one middle number, you are done with the median. If there are two, then you have to add them up, then divide that by 2.
Mode:The mode is the middle number in a set of data. It is the number that appears most often. To get the mode, you have to arrange the numbers in ascending order (to make it easier), then look for the numbers that appear most often.
