Carrie's Last Fraction Post

Monday, May 11, 2009
The first thing you have to do when adding fractions is to find the common denominator. Then you add together the numerators and add the denominators together. The last step is optional, you reduce or simplify your answer (the fraction) if you can.
















When you're adding mixed fractions you can add just the whole numbers right away or you can convert the mixed fraction into a improper fraction. Once you've done that you have to find the common denominator, and then add all the numerators together and the denominators together. If you converted your mixed fraction into a improper fraction for your first step, you will have an improper fraction as your answer. You shouldn't have an improper fraction as an answer, so convert it into a mixed fraction. The last step is to reduce or simply your answer if you can.
















Subtracting fractions. The first thing you're going to do is to find the common denominator. The second thing you have to do is to subtract all numerators together and all or the denominators together. And the last thing you have to do is to reduce your answer or simply it if you can.
















Multiplying fractions is the easiest! All you have to do is to multiply numerator by numerator and the denominator by denominator, and reduce your answer if you can.
















Multiplying mixed fractions is almost the same as multiplying proper fractions, except you have to convert the mixed fractions into improper fractions. You do the same thing, like in multiplying proper fractions where you multiply numerator by numerator and denominator by denominator. Then you have to simply reduce or simplify your answer and convert it into a mixed fraction.
















When you divide fractions you have to find the reciprocal (the reciprocal is the fraction fliped up-side-down, what makes it a whole number.) Then use multiplication, multiply the numerators and denominators together. Reduce if you can.
















The first thing you have to do when dividing mixed fraction is to convert any mixed fractions into improper fractions. Then do the same first 2 steps in the previous explanation, then you convert it into a mixed fraction. If you can, reduce or simplify your answer.















I chose to do problem 2 & 3















Scribe Post for April 17, 2009

Sunday, April 19, 2009
Hi guys (: THERE'S ONLY 9 MORE DAYS UNTIL THE MUSIC TRIP ! YAAAAY (: Anyways, I'm doing one of the scribes for April 17. I'm going to show you how to do 6 questions from our assignments, and I'm going to the page where it says "Did You Hear About..."


The first question I'm going to do is letter C because it's the first letter of my name! Haha.
Okay so here's the question:
C. 9/10 + 1/2

- First you have to find the common denominator!



















The Second question I'm doing is letter F.
Here's the question:
F. 7/10 - 1/5

- The second step is to multiply the numerator with what you multiplied its denominator with then subtract or add the numerators together.



















The Third question I'm going to do is letter K

Here it is:
K. 9/16 + 15/16
(This question is really easy!)
- The third step is to reduce the fraction if needed.






















The fourth question I'm doing is letter L.
L. 7/10 - 8/15
(I sort of got confused with the subtraction and adding symbols, it's a subtraction question by the way!)
- Review: The first step you have to do is to find the common denominator between the two (or more) denominators. The next step you have to do is to subtract or add the numerators together. And lastly, you have to reduce the fraction if you need to.






















The fifth question I'm doing is letter M.
Here's the question:
M. (7/8 - 1/4) + 1/2

- This question is different from the others because there are brackets. When you have brackets you have to do what's in the first, then whatever is outside the brackets. Remember B.E.D.M.A.S.




















And for my last question I'm doing letter P.

Here I go:

P. A BigBurger has 1/4 pound of meat. A SuperBurger has 1/3 pound of meat. How much more meat is used for the SuperBurger?
P. 1/3 - 1/4

This question is simple, just use the steps I gave you.


I hope that my scribe wasn't that bad, and didn't have a lot of mistakes. Now I have to finish my other homework... So bye! Oh and before I forget, since there are 2 scribes I'm going to chose who's going to the next scribe at school (: bwuahah. ttfn.

Pythagaros

Thursday, February 26, 2009

The first artifact is a a right angle triangle, also known as 'R.A.T'. The square in the corner is the right angle, and it's not called a right triangle because it's on the right side (in this case its not on the right!) The right angle is an angle of 90 degrees. The triangle is made up of legs: A and B, and the longest side of the triangle or the part of the triangle that is diagonal from the right angle is called the hypotenuse. The acute angles are going to be Theta and Beta. Theta and Beta are called complimentary angles because together they form a 90 degree angle.






This second artifact is a square, this is a special type of rectangle. A square has 4 equal sides. Those 4 equal sides are called lines of symmetry. A square is made up of 90° angles, one at each corner. So the square makes 360°because 4 x 90° = 360°. In this picture, there are 2 right angle triangles.




This third artifact is the Phythagorean Theoem. This means that, if you know side "a" and side "b", then all you do is square them. So, you have to add them together, which leaves you the c" squared. Then find the squar root of the answer from your calculator, that will give you the length of side "c".

This is a statue of Pythagoras. He is the great greek man that made the Pythgorean Theorem and many more. He was the first known westerner to say that the Earth revolves around the sun. He was the only westerner to be allowed in pyramids, only one to speak fluent Egyptian language.


Pythagoras: The greatest genius ever lived. He is a "uber" smart mathematician, he was a Greek geek. It wasn't for sure that he was really alive or even existed.

Legs: These are connected to create the right angle of the right angle triangle a.k.a sides "A" and "B". They are also smaller than the hypotenuse.
Hypotenuse: The hypotenuse is the longest side of the right angle triangle, its the opposite side of the right angle also.
R.A.T: stands for Right Angle Triangle.
Greek : A person that from ancient modern Greece, also means that you lives or was born in Greece.
Theorem: A theoretical proposition, statement, or formula, something to be proved from other formulas.

PROBLEM#1:
In this problem that Mr.Harbeck gave us, we had to find the base of the triangle. This picture explains how I solved 'c'.

Problem#2:
First, you need to find out how long each side of the square is. Then that will give you side "A" and "B" for the triangles since they're both the same length. Okay so, like a normal question find the length of the hypotenuse, which is 'c'. Once you have gott that you can now label the triangle and add up all the sides to find the perimeter.

Scribe Post for January 9, 2009

Well I guess I'm the scribe today (: In class we were talking about a few questions . Here are some of the questions we talked about .




1st step: Is to rewrite the question.




2nd step: Group! Then you find the answer.




Here's another question we worked on. -2n=6


I was stumped on this question, and I think I still am, but im going to try my best to explain.



















First of all you CAN'T have a negative 'n'! It's like nothing = something, it's not right!

So, you have to change it to a positive. How? You switch negative 'n' to positive and and change the positive 3 to a negative 3.



"If you have a '-n' that is (-1)n. You must multiply each side by (-1)"



(-1) - n = 5 (-1) and that equals: n = (- 5)



Other than the stuff about changing negative n to positive n, there's one more thing that I almost forgot.



1/2n=5 ..&.. n/2=5 : They are the same thing. Just simplify, it makes it easier!



I'm soo sorry if you guys don't like my scribe post :( It was rushed, I'm soo busy. Please let me know if there's any mistakes, because I know there are many! I, myself don't like my scribe post so I'll update it when I have time. I'm sorry if it didn't meet your expectations... I still need to study it, so I can understand it better.



Well, ANYWAYS .. The next scribe is .... Ben, if you didn't already do one.



Pay it Forward

Saturday, January 3, 2009
For my act of kindness, I'm going to help anonymous people like the elderly, children, and the homeless. Some of my ideas to pay it forward was to help at an old folks home, help at the Children's Hospital, babysit for free, volunteer at a Christmas cheerboard, shovel someone's driveway, do community service, do chores at home without being told, and to donate money, clothes, or toys. I thought about going to the Children's Hospital or Calvary Place. I'm going to pay it forward during the break.

























What I ended up doing was I made cards with Abby, Alyanna, Arielle, Gelli, Sutchai, and Tracy. The cards we made were about paying it forward, explaining what pay it forward is, why we are doing it, and how others can help. We all participated and equally shared the work by thinking, writing, drawing, and coloring. On the front of each card said, "Pay it Forward" and to read before thinking to even throw it out or something similar. If you think about it, do you think you'd read something handmade made by anonymous people in the mail? Would you throw it out without even reading it? I honestly probably wouldn't take the time to read it, but maybe if it said something like, Please read before throwing out." or "Before you even think of throwing this out, please read it." I'd probably read it. We also drew pictures on the front of the cards like flowers, cartoons, and forward symbols like the ones on a VCR. In the inside of the cards basically covered the who, what, when, where, why, and how. We also drew diagrams of just one person paying it forward to three other people, each of the three paying it forward to three other people, and so on. We showed how it can spread quickly to many people and around the world. We also attached a lollipop to each of the cards to show our appreciation to pay it forward. We put the cards into mailboxes of unknown people. I felt that I have done a good deed by spreading the message to others. I also felt like watching someone open their door and read what we had left in their mailbox and how they would react. I think the people whom I have given it to would have probably had a happy feeling reading the card and had a smile on their face wondering who had made the cards. I'm hoping that the people who received the cards actually read it and don't tend on throwing it out.
I hope that they also pay it forward to help us spread the message.Do I think that one person can make a difference? I know someone can make difference, it may not be a huge difference like to stop global warming but everyone counts. Even if that difference is very little, it will continue to grow no matter how small if may be. It is almost like a tree, it'll start out small and it will take time for it to grow, but in the end it is a large beautiful tree, and all the waiting really paid off. I think if you really believe in yourself that you can make a difference in our world and that you never give up, you will make a difference. No matter who you are. Age? Size? Culture? Ethnicity? That all doesn't matter, what matters is what is in you! Every little difference can make a HUGE DIFFERENCE! EVERY PERSON COUNTS!
I also volunteered somewhere for Pay it Forward. I'm not sure if volunteering at an old folks home counts for Pay it Forward because I don't know how they could pay it forward. But I am a regular volunteer at Calvary Place, on Erin St. Lester and I volunteer together with Roldan Sevillano Jr, a casual at Calvary Place. Junior as we call him is the funniest guy ever!




















We learned how to push someone in a wheelchair so that we could transport residents to the Activity Room. In the Activity Room they have exercises where they stretch, have trivia games, BOWLING, concerts and entertainment etc. During the games I would most of the time be a scorekeeper or if someone wanted to go back to their room I would take them.

Lester and I have had some bonding time with residents, one in particular, Louise. She is the nicest lady, we walked with her around the 1st floor and there were only a few moments of silence. We found out that she went to school at Sargent Park! We talked about how nice it was at Calvary Place, she said it was kept very clean and that the nurses and volunteers are very kind.

We've been very familiar to most of the residents attending the activities even though Junior himself can't remember all of their names. Clara is a resident that stands out the most to me, she is so tiny, fast and energetic. Junior one day, decided to play a trick on me! He gave my bag to Clara saying he bought it for her... And he was like, yeah go ahead and look inside! I was like oh my gosh, and I didn't want to take it from her because that would be rude! Then Junior being Junior... takes a picture of Clara and himself, and then Clara figured that it was my bag. That's why she has that look on her face, she was saying that Junior should know better than to take someone else's things! ;P

Since we only helped out for the activities which finished quickly, we'd help them organize things like fixing a new calendar for the new month, which was what I did.















Lester and I have had so much fun volunteering there and are absolutely going to continue volunteering there when we have free time! (:

-Chapter 1

Adding Integers; Cinquain
Adding
Easy, Simple
Combining, increasing, solving
The answer is called a sum
Addition
Subtracting Integers; Tanka
No such thing as subtracting
You end up with a minus
You invert the sign to plus
Last you add its opposite

Partitive Division; Free Verse
It's staring you right in the face
Partitive, partitive , partitive
And you dont know what to do
Just follow along with me and learn
It's simple you see,
You need to share pieces equally
You make some groups
You make some tiles
Hand them out one by one
Until you're left with nothing, nada, none
So really it's just sharing equally (:

Quotative; Haiku
Circle groups needed
In the group of tiles
See how many groups

Ron's Rule; Free verse
Ron's rule as we call it, hard?
Not at all. Easy is much better!
All you have to do is listen
Multiplying an odd number of integers
Will give you a negative answer
Multiplying an even number of integers
Will give you a postive answer
Thanks for listening!


Chapter 2 Combining like terms and the Distributive Property

SCRIPT:
Lucy: Hey, how are you doing with the math work?
Vince: I'm doing pretty good! What about yourself?
Lucy: Well actually I was wondering if you could help me with this one algebraic expression... 'n+3-5n+12'.
Vince: Hm, it's not that hard you see. All you have to do is organize the terms, you circle like terms then regroup all of it. Then you simplify.
Lucy: I think the answer is '-6n+15', am I correct?
Vince: You circled 'n' and '-5n'... You regrouped, so then the expression should be 'n-5n+3+12'. Then simplified it should be '4n+15'. There's where you went wrong! Instead of adding a positive 'n' to '-5n' you added a negative 'n', that's how you got '-6n+15'!
Lucy: Oh really?! Wow, I never realized that I have made that mistake, and the answer should be '-4n+15'? ... Thanks for helping me, if you need some help I'll be there!

*A few minutes after working in silence.

Vince: Hey, since you said you'd help me if I needed it, could you help me with just this question... '2+4(3n+8)'. I came up with the answer '12n+10'.
Lucy: This uses the distributed property: '4(3n+8)' and you use bring down 2. You have to identify your terms inside the brackets, which are '3n' and 8. Then the next step you multiply '3n' by the number 4, and 8 by 4. Then if it's properly simplified the question should now read: '2+12n+32'.
Vince: That's what I wrong! I see now, continue please.
Lucy: You then circle the like terms 2 and 32. Reorganize the expression, then combine like terms! Then answer should be '12n+32'.
Vince: Oh! Thanks for helping me solve the question!
Lucy: You're welcome!
Vince: Hey, wait!
Lucy: Yes, what?
Vince: Do you want to go to lunch together?
Lucy: Sure, of course. Thanks!

The day passes..
THE END!



Chapter 3: One Step Equation Solving

Additive Equation: The first thing I did was isolate the variable by adding it's opposite; (-4). The next thing I did was to balance the equation by doing the same thing you did to one side to the other. The equation should now look like this: -4+4+n=6-4. Then I cancel out the zero pairs! Now you should be left with n=2. Verify is the next thing you do, replacing the variable with 2.














Subtractive Equation: Isolate the variable by adding the opposite of the constant; (-4). Balance it out doing the same thing to the other side: x-4+4=8. Cancel out, and you should be left with x=12. Don't forget to verify.













Multiplicitive Equation: Isolate the variable, divide by 2 on both sides so they're balanced! Then all your left with: n=8. Now all you do is verify, you replace 'n' with 8: 2(8)=16. Does that work? YEAH! 16=16









Divisive Equation: The first thing you have to do is to isolate the variable just like all the previous ones. What's the opposite of dividing by 5? Multiplying by 5! Then don't forget to balance the equation out, by doing the same thing to the other side. Zero pairs should be gone now! The last step is to verify, to make sure it's correct. 2=2

Today we talked about SUBTRACTING INTEGERS!! We did some questions in our yellow booklet, and I'm supposed to talk about what we did during class. These are the notes I took down during our class.

Subtracting Integers
-you do NOT subtract integers ... Mr. Harbeck says there is no such thing as subtracting ^o)



.. You know what to do? You add its opposite! LOOK!













Using integer chips you do this, look at it carefully:














Hopefully, I did this correctly and that my explanations were clear.. ;S I rushed this because I have a ton of homework -.-' I better get started on that, and before I forget ... The next scribe is ... (suspense) NICOLE N. sorry dude, I picked randomly!!

Carrie's Integer Story

Sunday, October 26, 2008
The day started as another typical day for Dora The Explorer, waking up in the mourning, getting dressed, and then leaving with Boots. Dora was told by her mom to bring her grandma some cookies because she wasn't feeling that well. She searched for the basket of cookies but she could not find them anywhere! Instead she found a note saying "To find the basket of cookies you must solve this math question: (-22)+(+16)+(-3)= ___ " Boots and Dora try their hardest to figure it out, and in a few minutes they solved it! Their answer was...



All of a sudden another note was found on the table saying "Your mother has just finished cooking them in the oven, they are on the ledge of the window cooling but you must put them into the basket." As Dora and Boots were taking the cookies and putting them inside the basket, they saw Swiper trying to sneak around to steal some cookies!! But instead of saying "Swiper no swiping" they gave him an integer question, dun dun dunnn ! The question read (+12)+(0)+(2)=__ . Swiper couldn't solve the question and ran away in fear! Dora and Boots solved the question just for the fun of it, the answer they got was...



Just as they were leaving the house Dora and Boots felt strange, like they were missing something... But they didnt know what it was! They left the house and closed the door thinking the strange feeling they were having wasn't important. They were walking on the sidewalk singing, as usual, and then Tico the squirrel comes running up to them panicing! Tico yells "RUN! RUN!" Tico is running as fast as he could down the hill, chasing after Boots and Dora. They run for their lives down the hill, and then ... Big integer chips are rolling down then hill! They have to count how many postive numbers are rolling down the hill and the negative chips too, and add them up to make them stop rolling down the hill. (-12) negative chips rolled down the hill and (+5) positive chips rolled down the hill. They figured the question was (-12)+(+5)=__. They added quickly using the integer chips, and finally figured it out! "We are saved!!!" they yelled in joy!
It is 9:30 in the mourning and Dora says there's is more time in the world to get to grandma's house! In the next few minutes, she checks her wrist watch to see the time, but then this time she looks up she saw Swiper again trying to get some delicious cookies! He used Dora and Boots' plan to get some, he gave them a integer question and only 30 seconds to do it because he was soo sure it was impossible!! (0)+(0)=__. and .... They solve in with 10 seconds to spare!! Again, Swiper runs away with fear and wondering how they solved it.




"Oh my gosh!!" Dora said. "I forgot my keys to my house! That was the weird feeling I had earlier! Ohh no, what am I going to do?" .... TO BE CONTINUED (;
Continuation:
We're almost there (Grandma's house!!) I have to hurry, before mom leaves the house for work!! They get to her house. Dora and Boots knock on the locked door, yelling "Grandma, open the door! Hurry." Grandma doesn't come to the door right away, while waiting a bird flies towards them and drops a piece of paper. It read: (-3)+(-12)+(+17)=__ You must answer this question and you will find the key that opens the door. Dora yells out the answer right away, "The answer is positive 2! Mysteriously Grandma opens the door.
"Grandma, we brought you some cookies! Oh yeah, we're kind of in a hurry and need to get back home soon! I just found out that I forgot my keys at home." Dora says quickly.
"You kids can use my phone! It is right there in the living room." replies grandma.
"Oh yes, I forgot that we could call home from here!!! Thank you!" said Dora.
Dora and Boots run as fast as they could, trying not to break anything valuable on the drawers. They find a note lying on the telephone saying "Sorry but the phone does not working momentarily, if you do want to connect it right now please hold 2 down."
Dora picks up the phone and listens for the dial tone. She hold the number 2 down, just like the note said to. There is a voice on the phone, a mans voice.
“If you want to connect the phone now please answer this question: (+4)-(+1)=__”
Dora knew this question right away!
“The answer is (+3)!”yells Dora.
She calls her mom, her mom is luckily there and Dora and Boots get home safely! The end... or is it?
