Adding Fractions and Subtracting Fractions

How?

-You change the denominators if they are not the same, then add the numerators.
Eg.























-If it's mixed numbers, you do the same thing and add the whole numbers too.
-In subtracting you change the denominators if they are not the same, then subtract the numerators.
Eg.
























-If they are mixed numbers, you do the same thing and subtract the whole numbers too.
Eg.


























Multiplying Fractions
How?
-You multiply the numerator by the numerator, and the denominator by the denominator.
Eg.



















-When you multiply mixed numbers, you change them into improper fractions then you multiply the numerators and the denominators, then change it back.
-When you multiply a whole number by a fraction, you put the whole number over one and do the same thing, multiply the numerator by the numerator and the denominator by the denominator.
Eg.
























Dividing Fractions

How?
-You could find the reciprocal of the second fraction and then times both of the fractions together.
-Or you can make a T chart (but it may not work every time).
Eg.






















-But before you do this, make sure you ask the question: How many groups of __ are in ___?
-When you divide a mixed fraction number, you have to change it into a improper fraction, then when you get an answer, you change it back.
Eg.























-When you divide a whole number with a fraction, you put it over one and finish the process of dividing fractions.
Eg.

Today in class we went over our homework, the 4 adding fracion questions and the 3 word problems. Here are the correct answers:



1) She can make the cake whole again.


5/8 + 1/2=9/8 or 1 1/8


5/8 + 1/2 change to 4/8= 9/8 or 1 1/8













2) 1/2 fraction of a package of buns is needed for the hotdogs.

12/8 = 1 4/8 = 1/2




















3) She has 1 7/20 L of punch.


3/5+1/2= 1 1/10


1 1/10+1/4=1 7/20


















We also added a few mixed numbers.

















For homework we got subtraction questions.


3/4 - 3/8=


Subtracting fractions is just like adding fractions, you change the whole but instead of adding you subtract.

Here are the rest of the homework questions.

5/8 -1/3 =

4/5 - 1/2 =

13/15 - 4/5=

The Pythagorean Theorem

5:44 PM

(0) Comments

I will be talking about Pythagoras and his Theorem.

This was the first artifact.

Pythagoras was born in 569 BCE. He was greek and a vegan. He was the father of mathimatics, the father of geometry, the father of music, the father of harmonix, father of merchant, father of philosiphy, which is love of wisdom, father of vegetarians of Egypt, and the founding fourth father of western civilization. He was a very smart man (because he is the father of almost everything). He discovered mathematical relationships for the musical intervals, harmontix ratios, and the overtone series. He thought that using harmatic frequeceis and sound, that you could heal the sick. He was the first person to think of music, as medicine. He aplied priciples of harmonix to everything such as music, art, architecture, ect. He lived for about 100 years. He discoverd the theorem - a^{2}+b^{2}=c^{2}. He was the first known westerner to clear, earth round. He discoverd that the earth was a sphere. He discoverd lots to do with the solar system and the sun. He lived in Egypt for most of his life. (Was he ever smart!)



This is the second artifact.
-If you know the meausurement of at least 2 sides of the triangle (a,b or c) you can find the third side using this theorem.
-Pythagoras discoverd this theorem.
-His theorem required a right triangle (R.A.T).
-He discoved that the sum of the square on the two legs are equal to the square on the hypotenuse.




This the third artifact.


-This artifact is a right triangle (R.A.T).
-It is part of the theorem that Pythagoras proved.
-The right triangle has one 90 degree angle.
-The triangle is half of a rectagle or a square.
-The whole triangle equals 180 degrees.
-Theta and beta = 90 degrees





This is the fourth artifact.




-This artifact is a square.
-It has four 90 degree angles.
-This square is 2 right triangles (RAT) put together.
-Is a quadrilateral
-Is a total of 360 degrees
-supplementry


Vocabulary:

Hypotenuse- the longest side of a right triangle (the side across from the right angle)

R.A.T- Right Angled Triangle (a triangle with a 90 degree angle)

Theorem- a mathimatical statement that is demonstrated

Greek-a person who is from Greece.

Legs- are the sides of a right triangle that form a 90 degree angle


Problem 1

This diagram shows the game plans for a game designed by Harbeck Toys INC. The board is made up of a square and four identical right triangles.

















If the central square has an area of 225 square centimetres what is the perimeter of the board game? Show how you know.



My Answer:





















and the perimeter.




















p=s+s+s+s+s+s+s+s+s
p=15+15+15+15+21.213+21.213+21.213+21.213
p=144.852


Problem 2:

Today in class we had to move to Mr. Penner's room instead of Mr. Harbeck's. Mr. Harbeck had an inservice so we had a substitute. We went over our homework. He called up a few of us to write some questions on the board. Let's review from yesterday.


1. Isolate Variable

2. Cancel Constant

3. Balance

4. Cancel Multiply

5. Balance

6. VERIFY


eg.













And with tiles it looks like this.



















We didn't do much in class, just reviewed abit on algebra tiles. We had homework though. It was the white sheet our substitute gave us. Section 10.2 Extra Practice.















We had to choose 2 questions from question 1 and 2. The rest of the questions we had to do all of them. We had to draw all in algebra tiles.
For next scribe post I choose Melanie! Thanks for reading, please leave a comment!

Pay it Forward

11:05 AM

(3) Comments

We watched a movie at school called Pay it Forward. The message in the movie is that one person can make a difference - but can someone really make a difference? We don't know, that's why I'm going to do a project; I'll Pay it Forward. We have to do one act of kindness this holiday. So who should I help? I should help my little brother. I saw he had a hard time reading. What am I going to do? I decided to help him read. Where am I going to do this? I was thinking about a quiet place, where no one could interrupt when he was reading. When am I going to do this? I would help him everyday over the holidays so he will get it right and improve.



















Here is a picture of me helping him.

I've been helping him ever since the beginning of the holidays. He improved and got better at reading. He was happy that I helped him and I was too. He asked what to do in return I said, "Pay it Forward." He didn't know what Pay it Forward was so I told him. I said I help him and he has to help someone else and they help someone and so on. He told me that is too big of a job but I said it could be anything simple. I told him you could Pay it Forward when your older but don't forget the idea. He was stunned at first then thought about it, he told me he liked the idea that he would Pay it Forward.


So can one person make a difference? I believe one person can make a difference. If you can find the time to make someone feel happy that is something huge, you just made a difference. When the person asks what to do in return tell them to Pay it Forward. When that happens, it will go on and on and on. So yes, one person CAN make a difference and WILL.

Adding Integers: Picture

















































Subtracting integers: Haiku



minus, decreasing

Quotative Division: Free Verse










Quotative Division,



is not like addition.



Everyone knows that,



except for a rat.



There is a plan,

How many integers



are in an integer?



You found the quotient,



your independent!












Partitive Division: Free Verse

Partitive Division,
can be so very tricky,
but if you use it properly,



it will be less sticky.



if you learn how,



and come across a question,



you'll get through it easily,



and Partitive Division is what you'll be best in.



Try an integer,



such as positive eighteen.



Cut it into six groups,



and you'll get positive three.






If you followed,



the steps I told you,



you'll find the quotient,



and you can say "I know it!"







The Rule for multiplying integers: Free Verse










Multiplying an odd,



amount of negatives,



the product is negative.






Multiplying an even,



amount of negatives,



the product is positive.

The First video:







Carolina: I love this restaurant, Algebritic.
Daniel: Me too.
Carolina: What do you want?
Daniel: I’ll have a pie.
Carolina: Only a pie?
Daniel: Well it’s free if you can answer this question.
Carolina: What question?
Daniel: n+3-5n+12
Carolina: Oh. But you are not good at math you failed this year. You are going to summer school.
Daniel: You didn’t have to say that out loud and I was hoping you could answer the question for me instead of you paying an awful lot of money.
Carolina: It’s summer; don’t make me do your dirty work for you, besides I’ll just pay for it instead.
Daniel: 10 dollars for a piece of pie, go ahead if you want then.
Carolina: 10 dollars for one piece of pie?!
Daniel: Well yeah, we could just answer the question.
Carolina: Okay then but you try first, it’ll help you with your math skills if you try it, if you get it wrong, I’ll answer it for you, deal?
Daniel: Deal.
Carolina: First of all, you combine like terms, try doing it by your self first and see what you did wrong. The question is n+3-5n+12.
Daniel: Okay…I’m done.
Carolina: What did you get when you combined like terms?
Daniel: -6n+15
Carolina: No, you’ve got it all wrong, that’s the wrong answer.
Daniel: I’m not wrong!
Carolina: No Daniel, you are wrong. Walk me through, what did you do?
Daniel: Okay, I combined like terms like you said, n-5n and 3+12. N-5n is –6n and-
Carolina: See, that’s where you messed up.
Daniel: What? I was taught to do that though.
Carolina: You added instead of doing subtraction. N-5n is –4n.
Daniel: No, it can’t be, I’m…Right.
Carolina: Shhh, it’s okay, everyone makes mistakes. Picture n as 1.
Daniel: I already know that, I just don’t understand integers.
Carolina: What is 1-5?
Daniel: -4
Carolina: Exactly, all of the numbers and letters are screwing you up, just think of it the way I asked you.
Daniel: Okay, I’m starting to get it now.
Carolina: Good, you’ll do well.
Daniel: Thanks for helping me.
Carolina: No problem! Now lets get that pie!











Here is the second movie:







Daniel: So what are you getting?
Carolina: I don’t know what is there?
Daniel: Take a look at the menu.
Carolina: Okay…I guess I’ll have some fried chicken with fries.
Daniel: But there is another integer question.
Carolina: Ohhh, not again.
Daniel: The question is 2 + 4(3n+8)
Carolina: Oh no! Not again!
Daniel: I’ll answer for you if you don’t wa-
Carolina: Nah, you might get it wrong again.
Daniel: Fine then.
Carolina: Okay, I’ve got it, 12n + 10.
Daniel: No, that’s wrong!
Carolina: No, it’s not, I’m smarter than you!
Daniel: Yeah I know, but you make mistakes sometimes.
Carolina: Fine then but I doubt I made a mistake, show me Mr. I know more!
Daniel: Sorry but I’m just helping, anyways, for this question I use Distributive Property, 4(3n) is 12n.
Carolina: Yes, I know, I don’t see what I did wrong though.
Daniel: Wait let me talk. After that, 4(8) is 32. Son now we have 2+12n+32 we combine like terms, 2+32 is 34. And the way we simplify it, it turns out to be 34+12n.
Carolina: Man, where did you learn that all of a sudden, Daniel, I’m supposed to be the smarter one? But you were right for once. I’m not the best in Distributive Property, I didn’t get it but now, after you explained it, I’m starting to get it.
Daniel: Well, you helped me, so I helped you.
Carolina: Who said you helped me?
Daniel: Well, I did. You know, just because your smarter than me doesn’t mean you have to be all rude.
Carolina: Stay calm, I was just joking.
Daniel: Oh sorry about that.
Carolina: No problem. But I’m getting hungry now lets order our food!

Today in class, we talked about multiplying integers. We were recorded by the smart board. Mr. Harbeck and Mr. Baché gave us 2 pieces of paper. One was blue and the other one was white. (we only used the blue paper for today.) We had to fold it and make it into eight squares. We opened it up and only kept the 2 flaps folded in. We cut on the middle of the paper so there
would be 4 doors, 2 at the top and 2 at the bottom. At the end, it should look like this:

















On the first flap (++) we opened it and wrote:

(+2)(+3)

When brackets are touching we multiply

Make two groups of 3.














For homework in our (++) Multiplying Integers Sheet (blue) we had to make up a question draw a picture here is what I did:


(+3)(+5)

For next scribe I choose Shaneille. So I guess I am done now. Thanks for reading my scribe post. Please leave a comment!

Part 1

That was where it happened. The death of my brother right in front of me. My brother, Michael, we never really got along that well. At the end we both discovered the meaning of life. It all started at home. I had this project at school. Micheal never liked school he always fooled around and never payed attention. I was a good Honor student. Micheal damaged my project and I got really mad. I told mom and she said
"He'll learn." She always says that its like she never cares. I redid my project it looked so bad and I only had 1 day to work on it. It was a math project. Math is my favourite subject because it is so simple to understand.
My brother says I'm a homework freak especially when it comes to math. Its true its just he tells all of his friends and they laugh. He is so popular at school. So when he tells them something it passes on around the whole school that's what I hate the most.
The next day I handed in my project and my teacher was disappointed in me. The whole class laughed and made fun of my new project. When ever that happens I always feel like I want to run away.
That night I snuck out and my brother followed. He found I was acting very very strange because I'm not really like that. I was walking toward an unusually looking tree. It wasn't just any tree, it was very huge. I went closer and closer. There was a huge opening and I went in to see what was inside. My brother followed me in and that was where I noticed him.
"What are you doing here?!" I said.
"I went to follow you because you snuck out your not usually like that, that's more like me."
Then all of a sudden I heard this voice. Micheal heard it too. It was very deep.
"Hello! You just entered a world of darkness. In this world you can never come out unless you are smart enough to get through good luck! Ha ha ha!"
"What was that all about do you know Micheal?!"
"Who knows we'll have to see for ourselves."
"Okay than. Here we go!"
Then we ran into a huge bright hole. At the other end there was a whole new world. A world of integers. We walked forward and there was a sign that said,












Then my brother went ahead and didn't care so I went along. If only I'd listen to the sign. If only I told my brother to come back maybe he wouldn't have died.
We kept on going and there was another sign that said,













We were stopped by an integer sign. It said,

















I called out the number 0 and my brother did too. Then the same deep voice came in the middle of now where.
"Correct you may pass."
"That was weird." Micheal said. "It seems like he wanted to strangle someone."
"I know." I said.
We walked for a long time and it was very awkward. My brother and I didn't talk because we were too weirded out of what happened so far. And I was too mad at my brother anyways. We just walked and walked hoping to come to an end. But it didn't - we just had more integer questions to solve. We couldn't move all of a sudden.
"I'm stuck." I said.
"Me too." Micheal said.
"Aghh we are stuck in a pit. How are we going to get out?" I said.
Than the deep voice said,
"You must answer the following question!"
"Aghhh not again!" Micheal said.











"I know this." Micheal said. "It's -17"
"Yeah it's -17." I said.
"Correct." The deep voice said. "You may pass."
Then the I started to feel my fingers as the sand came off my body. Micheal was out already as my feet were still stuck in the sand. I pulled myself out gasping for air. I was so exhausted.
We kept on walking and this woman was at a gate. She said you can't pass unless you can answer this question.












"That's easy!" I said. "+1"
"Yeah +1." Micheal said.
"Correct" the woman said. "You may pass."
"That woman looks so mad." Micheal said.
"Yeah but I wonder how many more questions there are I like math but not like this." I said.
We kept on walking farther and farther. Than all of a sudden my brother and I were stopped by this man. He said we'd had to answer this integer question and if we got it right he would let us go if we got it wrong he'd still let us go but I thought he was lying. He was very unusual, but I said fine and then he gave it to us.








"That's easy +20." I said.
"What about you." the man said.
" Its not +20 that one is easy its -20" Micheal said.
"The answer is +20 you were wrong. Then he took Micheal away and he came back after and said to him,
"You were wrong so BANG!" and he knocked my brother out and I yelled at the man.
"Are you crazy are you insane why did you kill my brother?!" I bursted to tears "He is only 15, and why did you kill him right in front of me?!"
"Well didn't you see the sign at first it said you should turn back danger is ahead remember! You have to know your integers to be able to leave this world plus you had many warnings!"
"Whatever but you will pay for doing that!"
And I ran off in tears seeing my dead brother on the ground just ripped me to pieces. I didn't look back.

To be continued............................



Part 2

I ran off hoping I could leave this integer world of darkness thinking about my brother how much I missed him already. Than all of a sudden the same man who killed my brother went up to me and said,

"You must answer this int-" I cut him off and said,

"Just go away, leave me alone you killed my brother just because he got 1 integer question wrong! You evil killer! GO AWAY!"

"Just answer if you want to get out! I did not make up the rules! I am controlled! I was stuck here because I didn't answer any questions. I was too depressed because my sister is lost in this world and I tried my hardest to get her out and I hadn't seen my family and sister for years now! So do you want to end up like me? Just answer the question already!" The man said.

"Okay then give it to me then, I just can't believe you." I said.

"You must answer subtraction integers but there is no such thing as subtraction good luck." He said. He gave me the piece of paper and it said,
















"How am I going to do this question if I can't subtract?" I thought. "Think, THINK. I've got it I'll have to add the opposite. I turned the piece of paper around and wrote,











"The answer is -4." I said.

"Correct you may pass." The man said.

I ran not looking back then the man was killed when I saw him fall to the ground all of a sudden. I was scared. I ran faster and saw this girl just standing there.

"Hello?" I said. The girl didn't answer. "Hello?" I said again. Then she started to cry. "Are you okay?" I said.

"I just can't seem to get out of this place. I found out that my brother died, I saw some one fall to the ground, I just know it was him." She said.

"Don't worry my brother died too not to long ago. I was just talking to your brother, he told me he was trying to save you but he is being controlled." I said.

"We can get through this together then." She said trying to hide her tears.
"We WILL get through this together." I said. "By the way what’s your name?"
"It's Lucy and yours?" She said.
"Margo." I said. "Nice to meet you." and we ran off together waiting to be stopped by another integer question, I just made a friend!



*******




We walked and walked and then that deep voice was there again.

"Answer the following integer question."

"Its that voice again have you heard it before?" I said.

"Yeah! Its freaks me out." Lucy said.

"What do you want?" I said to the sky. "LEAVE US ALONE!"

A paper fell from the sky it said,














"Shoot I've never really got algebra tiles." Lucy said.

"Don't worry I'll teach you." I turned the paper around and wrote,














"Oh I'm starting to get it." Lucy said. "The answer is 0."

"Yes, it's 0." I said.

Then the deep voice came again and said,

"Correct you may pass."

"Who are you?" I said.

"You must not talk back, my brother did that and was controlled and he was taken away from Me,” she said sadly. "I always think it's my fault for jumping into the tree."

"I know what you mean." I said. "My brother died because he didn't know an integer question, killed by your brother." I realized whom I was with! "Your the sister of the killer who killed my brother!"

"He isn't like that, I'm telling you!" She shouted, "He's controlled by the deep voice!" She started to cry. "I'm sorry! I know just how you feel! Margo, don't make me leave you because you’re just ignoring me!"

"I know. I'm just thinking what my parents are going to say when I come home with no brother." I said.

"You know the deep voice is a mystery. He has a voodoo doll of everyone! He only lets you out if you are doing well with the integer questions." She said.

"You've got to be kidding." I said, "There is no way to get out now."

"Lets get going then." She said. And we ran ahead. We kept on walking. Then we bumped into something huge.

"What could it be Lucy?" I asked. Then all of a sudden the huge mystery thing turned around and it was a huge elephant! But it wasn't just any elephant it was an evil elephant. It stomped its feet in anger.

"I think we woke it!" Lucy said.

"You think!" I said sarcastically. Then the elephant chased after Lucy and she ran and ran.

"HELP!" she yelled!

"I'LL SAVE YOU JUST STAY CALM!" I shouted. The elephant picked up Lucy and waved her around.

"HELP!" She yelled again. It tied her up and put her in a cage. The elephant yelled,

"You must answer the following integer question!" It was the deep voice!

"Let her go!" I yelled.

"Just listen to him he'll kill you!" Lucy yelled.

He dropped a piece of paper again. It said,












“Shoot he only gave me 10 minutes!” I thought! “I have to do this for Lucy.”

“HELP!” Lucy yelled.

“Don’t worry Lucy I’ll save you!” I yelled. I turned the paper around and started to write,










“Here! Now let her go you evil elephant!” I shouted.

“Margo!” She yelled.

“Just wait he’s checking it I’ll be there.” I yelled back.
“Okay but hurry!” She said. As the elephant was checking it, I felt so scared thinking that he was going to kill her like the man killed my brother – I’m not going to lose any more people any more.
“Correct but you didn’t show your work!” He said happily and joyfully.

“NO!” I yelled. I was so mad. I looked around and saw a knife. I ran toward the evil elephant in anger stabbing him rapidly making sure he’d fall. You don’t know how wrong I was.

To be continued………………………..
