Joseph's 2 Minutes to Make a Difference

Tuesday, May 19, 2009
This was a Vietboyz Production(Joseph, Liem, Kevin and Vincent).
Our video was about what obesity can do to you, how to get rid of obesity and what not to do. It was trying to get people to stop their bad habits and to become healthy, or to make someone help someone they know has a problem. It also talks about the good things that come with obesity. Please enjoy and take action!

Pythagoras

Tuesday, February 24, 2009

Okay, well Mr.Harbeck apparently fell, hit his head and suffered Amnesia! Don't worry he's probably okay except he thinks that we are ALIENS! Oh, there were some things in his backpack, in which he was going to teach us in class. We need to figure out what these artifacts are and how they are connected to each other. All of that, before he regains his memory!!!!!!










This is a right angle triangle(R.A.T). You know it is because it has that little square that tells you its 90°. Well the 90° is mde by two parts of the triangle( theta and beta). Those to angles make the L shape (complemetry angle). The side left over is the longest side (the hypotenuse) It is often labeled as "C". The two smaller sides are labeled as "A" or "B", it doesnt matter which one is labeled what, but usually the base is "B." The sides labeled "A" and "B" are called the legs of the triangle. REMEMBER THAT: LEGS!


This is a special type of rectangle. It's a square! A square has 4 equal sides. You can tell that it has 4 equal sides because it has those lines on the sides(lines of symmetry). A square is made up of four 90° angles, one at each corner. The whole square makes 360° because of the four 90° angles. In this square, there are 2 right angle triangles. You know this because if you cut a line from one corner to the opposite corner and it'll make the 2 R.A.Ts.



This is the Pythagorean Theorem. So, there was this guy named Pythagoras and he came up with the theorem to find out the length of a side of a right angle triangle. Well what the theorem means is that, if you know side "a" and side "b", then all you do is square them. From there, you will need to add them together, which will leave you with side "c" squared. Find the square root of the answer and 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. You seem interested so I will tell you more. He is known as "The Father of Mathematics and Geometry", 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, and not suprisingly he spent a lot of time in Egypt! Pythagoras liked to work with harmonics just as much as he liked math, and he died at around the age 90-100.






So now is the time to see how all these item are related to each other. I'll start with the R.A.T, it is related to all these artifacts because two right angle triangles make a square, the Pythagorean Theorem is used to find the length of a side for a R.A.T, and Pythagaros is the one who made the theorem fo rthe R.A.T.


The square is related to the right angle triangle because you can cut the square to make 2 right angle triangles. It is related to the Pythagorean Theorem, by the fact that when you add the side squared it's like and is the same as adding two squares together.


The Pythagorean Theorem is related to the R.A.T because the theorem is used to figure things out for the R.A.T. It is related to Pythagoras because he's the great man that made the theorem. It is related to the square because it is used to add the sides together.


The statue of Pythagoras is related to the R.A.T because he made the theorem for R.A.Ts. It's related to the square because it's part of the theorem he made and it'srelated to the Pythagorean theorem because he the one that made it.



Now it is time for 2 problem/question:







For this question you need to find out how long the base is of the connected triangle. But to do this you need to solve for one of the triangles first. Then after you get that, you just times it by two and you'll get the length of the 2 triangles put together.







This is the question: 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?


First, 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. Now, like a normal question find the length of the hypotenuse ( "C" ). Once you get that you can label the triangle and add up all the sides to find the perimeter. Remember the answer won't be precise because we stop at the thousandths place and remember to make a short sentence answer!




Here are 2 videos explaining the Pythagorean Theorem:










Pay It Forward

Pay It Forward

The morning after a very snowy night, I went outside to shovel my neighbour's walkway and around my house. When I looked at their walkway, it had already been done, so I just did my own house, so my parents wouldn't have to.






At first, I was going to shovel my neighbour's walkway and around my house because my parents weren't home. I decided to do my neighbour's walkway because I haven't seen them for a while and I heard that one of them was ill. As soon as I got outside, I saw that my neighbours had already cleared their pathway. I decided to just do my own house(front, back, and driveway) and make it look very clean, like a professional snow shoveller did it. It took a little longer than I had expected, but I still got it done. After I finished shoveling I felt a little cold and my fingers were numb. When my dad got home he told me that he didn't feel so well. He checked the mailbox and happily told me someone had secretly helped him shovel the snow around the house. Therefor I felt happy that my dad didn't have to shovel the snow, while he wasn't feeling well.


I think that one person can make a difference because it's like a dollar. If a charity was buying food for people with donation money. And there was a package for $1000, but they only had $999 because someone didn't donate their extra dollar, then that's a big difference for the starving people that don't get to eat once again. Now, besides just donating money to charity's, you could help people yourself and take nothing in return except for them to help other people. If everybody in Winnipeg or anywhere else did this than it could reach to the whole world, and that would give everyone at least one happy moment in life. Every person helping counts!

Chapter 1: Integer Poetry

Adding Integers (Haiku):
Increase the total
Two numbers becoming one
coming together

Subtracting Integers (Picture):
When you have money$$$$$$$
Don't even play with this math!
When you do, say buh-bye.........

Partitive Division (Free Verse):
Partitive Division
Used for dividing
In quadrant one or two
To use this technique
Just ask one simple question
That I think your math teacher should know
If he doesn't and you come to me
I'll scream in your ear and say
Look at your barn doors
Good grief

Quotative Division (Diamante):
Quotative
Fun, simple
Circling, counting, drawing
Learn, to pass school
Question, think, answer
Math, art
Division

Ron's Rule (Free Verse):
If your a negative integer
And you want to dance the multiplication pop
Learn from the master of cool
That created Ron's Rule
His name is unknown pogi
He might teach you for some candy
If you throw in a chocolatebar
You might be there listening
To him rapping out this old saying
You need to have an even number of negative integers
If you don't have that, you're just plain queer
When you do have that simple need
The crowd is sure to give
You a positive applause
Don't even think to go learn from
Pratt's Law or Mel's Rockpile
Cause there's only one
Multiplication pop

Fred: Hi

Jack: Sup
Fred: Are you ready for the math test tommorow?
Jack: I was born ready! Did you study?
Fred: No, I forgot to. I was out partying last night.
Jack: Billy Bob's party?
Fred: Yeah.
Jack: Well, I was studying last night. You should start studying now.
Fred: Of course, lets begin.
Jack: After an hour of studying. Are you ready now?
Fred: Yeah, I probably know everything already.
Jack: I bet you a dollar that you'll get this question wrong.
Fred: Sure, more money for me.
Jack: Okay, how about an algebra question?
Fred: Bring it on!
Jack: Hmmmm, n+3-5n+12. Simplify that question.
Fred: That's -6n+15.
Jack: Wrong! You just made one little mistake. This is how you answer it.
n+3-5n+12
n-5n+3+12
-4n+15
Fred: Oh, I get it now. I multiplied n with -5n, instead of adding them together.
Jack: Hooray, I get a dollar! Now, try this question 2+4(3n+8). Simpilfy it again.
Fred: Is it 12n+10?
Jack: You made the same type of mistake. This time you multipled the 2 with 3n, instead of
4 with 3n. I'll just explain the whole thing.
2+4(3n+8)
2+12n+32
34+12n
Fred: Yes! I finally understand! It's a miracle, I can simplify algebra things. I forgot what they
call those things.
Jack: So, your good for the test?
Fred: Yeah, you know how I roll. This is a very touching moment for me. I'm so lucky to
have a friend like you.
Jack: I love you to man!
Fred: Okay, don't go to far with it. HaHa!
Jack: Well I'm going to go home to get some sleep now.
Fred: Okay, peace out bro.
Jack: Peace.
Fred: At school, the next day, after the math test. Hey, Jack how was your math test?
Jack: I think I aced it. How was yours?
Fred: Same here, just because I studied yesturday.
Jack: Yeah, well I need to go to my next class now. See you at Joseph's party?
Fred: Yup, I'll see you there.
Jack: Bye

Hi, during class today we learned a lesson about multiplicative inverse. We also needed to add work in our barn doors on the division side in the positive & negative section(quadrant 4). To answer a division question with a positive then a negative integer, you must use multiplicative inverse.


hmmmm.....lets do 12 divided by -4. It seems impossible to do right? Well as a matter of fact it is possible. Try to do that question on your calculator. No, don't worry your calculator won't blow up! It works!

From what I understand, there are 4 easy steps to doing Multiplicative Inverse. First write the question using the division sign. Step 2 switch the answer(N) and the first integer and change the division sign to a multiplication sign. Step 3 Find the answer to N. Then fill in the question.



Your probably wondering what's wrong with just using partitive or quotative division. Well I'll tell you what's wrong: They don't work!

Quotative: How many -4's are in +12? It doesn't work because we can't make groups of -4 in a positive number.

Partitive: How many equal parts are in -4 groups when we have +12? It doesn't work either, because you can't draw -4 groups.

Let me think...........................................the next scribe is Maeddah!!!!!!!!!!!!!!!!!!!=P

Joseph's Integer Story

Friday, October 24, 2008
There once was a boy named Joey. He was very good looking, was not single, and was the very best Taekwondo fighter in Winnipeg! He was so good that he decided to join a tournament to see if he was the best in Manitoba. Joey trained everyday until he couldn't walk anymore. When he got to the tournament at the University of Manitoba, he saw that he would be fighting 4 different people. Joey went to the gym to get ready, when he overheard other competitors saying that the judges didn't know how to add up the fouls and points(integers). And to get your medal you had to add up the scores, a different way for every person you fight . Joey was so happy because he knew how to add integers in 4 different ways. What a coincidence!

About 30 minutes later, he was called to the ring. His first competitor was some guy named, no one even knew his name! Joey was winning like crazy, but then he "accidentally" hit the other guy in the groin area. Joey got a 2 point deduction. There was one more round left and Joey thought he was winning by far, so he left his guard down. Out of nowhere he got kicked like 10 times(pretty hard to do). They finished fighting and Joey got his score to add up. He thought about it and decided to just do "the math" for this round.





Joey won(of course).The next match up was Joey and his one and only enemy Arwen. He remembered it like it was yesterday. Joey got his first true girlfriend, Arwen was a really messed up kid. He was telling him lies, and "pretending" to mess around with his girlfriend. Joey couldn't take it anymore, so he beat the living $*&! out of him. When he was walking home a group of people and Arwen jumped Joey. He didn't know what to do so he just ran all the way home. Until this day Joey had never seen Arwen again. Just thinking about it made Joey mad. When they started the fight it seemed like Joey had pure adrenaline instead of blood. Arwen came in with a punch, Joey did a jump spin kick to the face, and knocked out Arwen to the ground, but while Arwen fell to the ground he managed to kick Joey once. From that kick Joey's knee fell on Arwen's head, giving him a 1 point deduction. Joey won by default, but he still had to count the score. Since they were small numbers he decided to use the "number line technique".



Of course Joey won again. He thought about which form of math and decided to use the "integer tile technique". He was fighting his former classmate Ricky that moved a year ago. Joey started the fight with a 360 degree spinning jump round house kick(tornado kick). It was so powerful that Ricky fell straight backwards and hurt his ankle. Luckily Joey knew that Ricky couldn't do that because his instructor taught him that kick the day Ricky moved. They continued to fight. They were about tied when the match was almost over. Ricky got a chance to look at the score screen and saw that they were both tied. He wasted time until there was only 10 seconds left. He risked it and tried to hit Joey with a triple jump kick. Joey just happened to do a side kick and knocked Ricky out before he could kick. Joey won at the last minute!



Okay, it was time for the last fight. Joey was versing the former champion Carlos. They both knew that either one of them could win the fight. They wasted half of the match just moving around, so they both got -2 points for not doing anything. Carlos had 6 points and Joey had 3 at 20 seconds left. Joey knew he would need to do a triple kick to tie. Luckily someone screamed, Carlos turned, and Joey had the perfect chance. He missed the last kick, and lost the match by 1 point. Joey did the last score with the "have and owe technique".





When they did a blood test they found out that Carlos had been taking steroids! That means that Carlos was disqualified and Joey was the best fighter in Manitoba! He will continue his journey to become the best in Canada


To be continued......


continued............



After that tournament Joey was so good that he had a chance to join the Olympics. Before he could, he had to fight the best in Canada. Joey had been training hard and had improved 10X better than before. He was lucky this time, he only needed to fight two people! Once again, the judges did not know how to find the answers for the scores and this time you needed to figure it out with subtraction and one mixed question.

The first round was a pretty boring match because no one wanted to lose. Finally, Joey did a kick and got kicked 3 times back. He thought" Dang this guy is fast!" Joey caught back up. Joey did a kick turn, kick turn, kick, on the last spin he got dizzy and hit the competiters groin(deduction). Then Joey was winning! He ended the match with the lead. Hopefully. Joey won, once again! As he drank some "water", he decided to use a simple subtraction method for this match. Let us take a look at his score.




Joey was still pretty tired when the last match up started. He was fighting the representative for Southern Ontario. Joey was keeping his guard up for now, but he was getting very weak! His coach looked at the water, then saw a bottle of sleeping water beside it. Joey must have drank the wrong bottle! His coach didn't know what to do. He thought and thought, when he remembered that he had a bottle of "Red Bull" in his pocket! He called a time out and made Joey drink some. When Joey finished he felt like he could actually fly! They started the fight and Joey was like a wild tiger. He was scoring point after point, none stop! By the end of the match nobody knew what the result would be.



Joey won by one point! He was the happiest guy in Canada! This year the organization was trying to pick a winner a different way. They had to add up their score from the last match with the previous to make it seem like one big fight. Let's have a look. It might look complicated at first, but you'll understand soon.


Lets see who gets to go to the Olympics for Joey's division. Representing Canada is Joey from Manitoba! The runner up is Arwen from Southern Ontario! Wow, Joey never recognized that guy as Arwen. Joey would now be going to the olympics with his enemy, maybe they will get one last fight in front of the world!

Today in class we continued on "The Gumball Machine" worksheet. Each table was given a cup with 10 blocks inside.(1 red, 2 Green, 3 Yellow, & 4 Blue.) We needed to select one cube randomly, tally what color it is, and put it back in the cup. We had to repeat this process untill we had reached 100 tallies!

For Homwork we are supposed to extend the tallies on the worksheet into one long one. Fill in the #5 question ( all 100 tallies). Then in question 6 we need to add up all the tallies for each catagory. After doing that you must take the number from each color put a percent sign at the end and fill it in, in question #7. For question 8 take the percents from question7 and plot them in the numberline for question 8.






We also went through the definitions of Theoretical and Experimental probability.


Theoretical Probability:is the ratio of favourable outcomes to the number of total possible outcomes (TPO's). ( Favourable/TPO)


Experimental Probability: is the ratio of favourable outcomes to the number of experiments.


Here is a video about probability:
