817 Math Blog

Today in math class, we were given sheets of papers that had 10 algebra questions on them. We had to only do 8 of those. For today's scribe, I'll help you with 4 questions of the 8, so you will only have to do four.

1. A certain number plus 26 equals 51. What is the number?
The number is __
Let N = number
N+26=51
N+26-26=51-26
N=25
Verify:
N+26=51
25+26=51
51=51
The number is 25

2. Three more than twice a number is nineteen. Find the number.
The number is ___
Let N = number
2N+3=19
2N+3-3=19-3
2N/2=16/2
N=8
Verify:
2N+3=19
2(8)+3=19
16+3=19
19=19
The number is 8.

3. Six times a certain number minus eight is forty. What is the number?
The number is __
Let N = number
6N-8=40
6N-8+8=40+8
6N/6=48/6
N=8
Verify:
6N-8=40
6(8)-8=40
48-8=40
40=40
The number is 8.

4. Terry has a certain amount of money and Rick has three times as much. If together they have $2.60, how much did each boy have?

They each had ___ dollars/cents.
Let N = Dollars/Cents
This one is different, so we must first identify what we know about each person.
Rick: 3N(We know that he has 3 times as much as Terry)
Terry: N (We don't know how much Terry has or anything about it)

3N+N=2.60
4N=2.60
4N/4=2.60/4
N=0.65
Verify:
4N=2.60
4(0.65)=2.60
2.60=2.60

They each had $0.65 cents.

That is all for today, I don't think we had any other homework.

(SORRY IF MY WORDS ARE LARGE, SOMETHING IS WRONG WITH MY COMPUTER)


Today in Class we did computer Stuff. So I'm going to show you step by step where to do and what to do.

- Electronic Portfolios

- First you go to http://spmath81708.blogspot.com/
- Than at the top their should be something saying E-Portfolios
- Click On E - Portfolio than at the left side - bar click on Math
- Than make a new Tab (Open a new internet)
- Than do the same on the first 2 step but now you scroll down and click on room 17
- Than you click your name
- Click on Edit this Page
- Now you Copy down what you need to do on Math.
- (example: Parent Information Heading 2 ) So you just type in Parent Information in as Heading 2

It already stopped though. Lol. So I miss everyone! Okay I better go just in case anything else happens. I MISS YOU GUUUYS!
Talk to you soon.
Bye.

Today in Math class, Mr. Harbeck showed us how to turn an algebraic problem solving into an algebraic equation and then answer it. I have chosen the last 3 algebraic problem solving from page 45 on the purple booklet, because a some people were having trouble answering them.

Here is my first example from page 45, letter C.

C. Three desks and a bookcase together weigh 157 lb. The bookcase weighs 34 lb. How much does each desk weigh?

First you have to write a simple sentence like: Each desk weigh ____.
To complete this sentence, you have to figure out the equation for this problem solving, and answer it then verify to see if it's correct.


3x + 34=157
3x + 34=157-34
3x= 123
3x/3= 123/3
x= 41

Verify:
3x + 34=157
3(41)+34=157
123+34=157
157=157

To finish it you will have to complete the sentence which is: Each desk weigh 41 lb.

Here is my next example. This example is also from page 45, letter O.

O. Oshgosh would like to buy a new pair of skates for $115. So far he has saved $40. If he earns $7.50 per hour, how many hours must he work until he can buy the skates?

For this kind of algebraic problem solving, we will do the same thing which is to write a simple sentence. The sentence would be: Oshgosh will have to work for ___ hours to buy the skates.
To complete this sentence you will have to figure out the equation for this algebraic problem solving, answer it and then verify to see if it's correct.


Now you will have to solve the algebraic equation.
7.50x + 40=115
7.50x + 40=115-40
7.50x= 75
7.50x/7.50=115/7.50
x=10

Verify
7.50x + 40=115
7.50(10)+40=115
75+40=115
115=115
To finish this equation you will have to complete the sentence for this algebraic problem solving. The sentence will be: Oshgosh will have to work for 10 hours to buy the skates.

Here is my last example. This example is also from page 45, letter T.

T. Mr. Piper's plumbing needed repairs. The plumber charged $98 for parts plus $45 per hour for labor. If the bill totaled $458, how many hour of labor wee required?

To answer this algebraic problem solving, you will have to figure out what the equation will be for this, and complete a sentence. The sentence will be: ___ hours of labor were required. Also, as always you will have to answer it and verify to see if it's right or wrong.


45x + 98=458
45x + 98=458-98
45x=360
45x/45=360/45
x=8

Verify (Always verify)
45x + 98=458
45(8)+98=458
360+98=458
458=458

Now, to finish off this algebraic problem solving, you will have to complete the sentence for this. The sentence will be: 8 hours of labor were required.


REMEMBER TO STUDY ALGEBRAIC PROBLEM SOLVING FOR THE MATH TEST ON MONDAY! (IF YOU NEED MORE HELP, JUST ASK MR. H).

Algebra Quiz 3

So, today in class we all had a math test/quiz (Whatever you want to call it) At the end of the quiz we corrected the answers.

On January 20th, 2009, in class, Mr. Harbeck taught us how to solve multiplicative algebra equations. He also reviewed how to solve adding and subtracting algebra questions. Thes are some of the questions he gave us to do in class and for homework.

Remember:
Isolate the variable
Cancel using
Opposite
Balance
Verify

These are some of the following questions that i am going to help you with:
3n+8=20

3n+8-8=20-8 (add the opposites and what you do to one side you so to the other)

3n=12

3n/3=12/3

n=4

verify

3n+8=20

3(4)+8=20

12+8=20

20=20

7x-2=61

7x-2+2=61+2

7x=63

7x/7=63/7

x=9

verify

7x-2=61

7(9)-2=61

63-2=61

61=61

Today in class we talked about what we are going to do for the quiz tomorrow. For the quiz, Mr. Harbeck is going to take some of the questions we did on our homework on page 43. We also corrected our homework from page 43, and 44. Today, our home work is page 46, and 45 in our purple book. On 46 we only have to do 6 questions, and on 45 we have to do E to W. Below you are going to see some examples of the kind of questions that you might see on the quiz tomorrow.

-The slashes that you see in the questions are dividing symbols.

1. -4y+16=4
-4y+16-16=4-16
-4y=-12
-4y/-4= -12/-4
y= 3

Vefification
-4y+16=4
-4(3)+16=4
-12+16=4

Hello people! I am the scribe yet again on this fabulous Tuesday! Today in the class of mathematics (math class) we were in Mr. Penner's room because it's day 6 and we do that from now on. Anyway, we went over one question that somebody had problems with. Then we worked on our *trumpet fanfare* Multi-Coloured Book (which is shown below)!

HEEEEY GUYS . Im supposed to write like a journal thing . (; So I will . lol .

I pick ... hmm , CAMILLE ! XD

Over the winter break we had to do something that is called "Pay it Forward", for my "Pay It Forward" i did was I take care of my Auntie son so yeah... Later on he was crying so i dint know what to do good thing i found a toy that is a car and he stopped crying.


Well it was okay for me because sometimes i do it while my Auntie is at work. I felt really proud of my self because i made my Auntie son stop crying.


Yes, anyone can make a difference just by making other people feel happy or proud of you.

Hi, my name is Richard for "Pay it Forward"I shoveled my neighbor's front yard. Well I didn't tell them to pay it forward because I don't really talk to my neighbor's my dad is the only one in the family that know him very well.

Well shoveling their front yard got me pretty cold, but then it didn't really matter to me because I'm use to it. I felt very proud of my self because i shoveled someone front yard.

Yes, i think one person make a difference because if you did something good for someone they would do the same for others.

COOKIES <3

Me and my cousin junelle. I didn't want to take a picture with a stranger soo.. yea
PAYING IT FORWARD.
for paying it forward i went bowling with my cousins and family. I handed out a pamphlet and 2 home made cookies to strangers who worked at the bowling alley. My pamphlet said " Little things can make a BIG difference". I told the people who worked there to pay it forward. They took it the wrong way because i said "pay it forward like asking for money or something", but i told them to keep their money and just give it to a shelter or to poor people, or kids ineed. They said they would. The reason why my cousins, family and I went bowling was because it was mine and my aunties birthday the next day and it was already school so we couldn't celebrate it. After my birthday party with my family was over they gave me money for a present almost 80$. Instead i decided that i didn't really need anything so i put most of the money in a donation jar in the bowling place. I felt really good because some of my money can be a good help to other people. Also in my uncles church we save a lot of money every year helping the kids in the Philippines its called "ga-wad kaling-a" gaaa- waaaad-kaaa-liiing - AH ''. Its for kids my age who dont have enough money to go to school and also babies who are really sick and dont have money to pay for medicine

For Pay It Forward I went out side and shoveled my yard and my 2 neighbors yard. I baby sat my little sister and my younger cousins . My youngest cousin is not such a patient kid she is hyper doesnt listen and so on. While i was doing these i was offered some money i said no thanks and just to Pay It forward .They asked me how to pay it forward i told my mom and i told my auntie and they both said they would . When i shoveled i went inside and made a letter or a card the card was saying " Hi i did your drive way no need to pay me Just Pay It forward. If they asked how to pay it forward i left a message on the other side responding to what Pay It Forward was .Doing these good deed made me think if people help one by one everythingcould change if we use the system Pay It Forward. I did enjoy doing this project.

The pictures that where taking could not be uploaded today but will be uploaded soon.

So for my pay it forward i shoveld my grandma and grandpas driveway because my grandma was out of town and my grandpa pinched a nerve in his rib so it was the least i could do. So i threw my jacket on but since i was at my grandma and grandpas i had no gloves so i askedmy grandpa for gloves and he could only find one so im out side shoveling there huge drive way with no touque and one glove but i didnt care cause i was helping my grandpa but after i was done i didnt think it was enough so I got out the snow blower and shoveld 5 more houses telling all the people to pay it forward even though i coulda made 20 bucks i refused the money and just told them helping other people would be good enough so they said they would and thats how i payed it forward

Well, I kind of forgot to do the scribe post for yesterday. But, here it is. :)

Todayyy in Class we worked with something called algebra tiles ^^
here is a video i made on youtube about what we did : D
it will be used with alot of different animations from a game that I play so enjoy.




if this doesnt work here is the link to it

uhmm so yea :D

Before the break we were all assigned to do this thing called ' Pay It Forward ' To be honest I'm not that type of kid who's going to do something without getting paid but whatever. To help pay forward i helped my dad shovel our lawn after his hard day of work, well apparently i did all the work because after 5 minutes he gave me the shovel and went inside watching me through the window. I was shoveling for about an hour since it was freezing cold last night. I told my dad not to pay me, well he wouldn't anyways but instead i told him to ' Pay it forward ' He asked me what's that? and i told him ' Instead of paying me back do something nice for someone else ' and he did, he did the laundry for my mom, haha. The other thing i did to pay it forward was find old clothes i don't usually wear anymore and give i to my mom, and fold it together so we can send them to the salvation army. I also told my mom to pay it forward and she was like ' ano ba yan ' which meant ' what's that ' and i told her the same thing i told my dad. Instead of paying me back do something nice for someone else, and i guess she did by giving clothes to the salvation army.

I didn't really have any idea of what I was going to do but I was not aware I had to do this. But over the break my Aunt, Sarah was moving out of my cousin's house so i helped her load the car with all her stuff. There was alot and we had to move quite a bit but I guess that that is a good thing to do. I also scraped the snow off my dad's car a few times. I dont know thats not much but thats what I did without asking for anything in return. I also helped my cousin with a few things but not really that important. When helping I felt good because i helped another person and I was happy that i was spreading a little bit of happiness.

Hi my name is Jai. Over the Christmas Break, I had to do an assignment called pay it forward. Pay it forward is an idea that sombodey had to improve people's lives. to complete this idea one person has to give an act of random kindness to 3 people. Then you will tell each of the 3 people that they have to the same thing that you did for them to 3 other people. The thing that inspired our teachers to even think of doing this is a movie called "Pay It Forward". All of the grade eights got to watch it on the last day before Christmas Break. In the end of the movie, it becomes sad because the kid who thought of pay it forward died when he was trying to help another kid in his class that gets bullied a lot. Below, you will see pictures of what I did for this assignment. It includes before and after pictures.

BEFORE











AFTER












To pay it forward I shoveled my grandma and grandpa's drive way. I decided on doing that because I slept over there. One more thing that I did for this assignment was give money to my uncle. Below, you will see the proof. The proof is a picture.










So now you see what I have done. Try this idea just for fun. Maybe you will see the beauty that we have created. If you carry on this thing we call pay it forward.

Hello and if you don't now me I'm Carlo. And I did this project called "Pay it Forward". Well at the holidays I didn't do anything that special, so somewhere close to New Years, December 31 to be exact. I did something super special asome in my house, then my cousins. Well I had to babysit my cousins.

Surprisingly unaccepted happened, my cousins came to the house and jumped on me literally. While there mom is somewhere in the outdoor world doing something. While I babysat them they were playing with there own and Nintendo DS. Just for a short moment of time they actually escaped my clutches , that means the ran away somewhere in the house doing whatever they do normally, now if you are wondering what the do normally is to fight, yes fight. I had to separate them but i just got bamboozled by the little one not the older one of the brothers but the young one. After that little brawl I gave something free to them like a DS game or whatever plea shay thing they wanted. So I gave it to them. Now that's how generous I am. For the following hours my sisters were video taping them as they cause havoc around the house, eventually we got videos. If you look down at this paragraph there is one of the videos we captured. Now I felt super special good when I baby sat for them. My cousins reacted surprisingly enjoyed on what I did to them. I asked them to pay it forward but they didn't know what I meant. So when we had the celebration of New Years in my other cousins house I said these to all my relatives in there to pay it forward as I explained slowly. And there was About 20 relatives in there. So they tried to to the things I said.

Now you see the videos on how I did well, the results on how I took care of them is I had trouble on it, but if I rate it to easy-insane I'd say normal. And can one person make a difference, I'd say yes. If I can do this some other person can do it. Yeah, that's all I got now I'm done

Hello people! My name is Rinorm and I can not believe I actually did something for this project. For the holidays we were asked to pay it forward by doing anything to help the world. For me, I decided to shovel my cousin’s driveway and my own driveway without charge.

I decided to shovel my cousin’s driveway because on a cold snowy night they phoned my mom and said they were going somewhere. I realized that they were going on a holiday so I said to myself, "I'm going to shovel their yard tomorrow." And that’s exactly what I did. The next morning I put on my shorts, jogging pants, undershirt, t-shirt, 2 sweaters, a jacket, two pairs of socks and shoes. When I walked outside I was so cold because I have just learned that it snowed a lot early in the morning. I went to their back driveway and started to shovel. When I finished the driveway I decided to shovel their walkway too so I did. When I have shoveled everything I went back to my house. When I got inside my dad asked me to shovel our own driveway and that is what I did. When my cousins got home they phoned us and asked who shoveled and I said me and I said “Pay it Forward please!” and they said that they would try to. I was very happy.
As you can see from this picture that i actually did this and I was very, very cold. Well I hope that I have encouraged anyone to "Pay it forward." I have to go now. Peace Out dudes and dudettes.

On the last day of school, we watched a video called Pay It Forward, and we had to do our own act of kindness for someone we know, or a stranger. I decided to help my Grandma, by shoveling her sidewalk and front yard for her. The sidewalk was filled with a lot of snow, and I should've did this earlier, but I came on the day before school starts. When we got there it was already dark, because it's Winter and we came at 5PM. I started shoveling the sidewalk first, because it was hard to walk through with snow nearly up to your ankles, then I helped a bit with the front yard, but it was almost all clear already because she had cleaned some of it herself.













After I shoveled the sidewalk and front yard, I went inside. She thanked me and I asked if she could try to do a kindness for another person, and I told her about the Pay It Forward project. She told me she will try to do an act of kindness for someone she knows and tell that person to do one for another, and so on. After that, I felt glad that she did not have to shovel all of that snow herself.
























I believe that one person, can make a difference in the world. All they have to do is do an act of kindness, and pass it on, and keep going. It starts to affect more, and more people in a good way, it's still making a difference. As long as the acts of kindness keep passing on, it will soon make a big, big difference in the world. That's how I see it.

Have you ever thought of helping someone out , without getting anything back? I know most teens think "Oh that's a waste of time!" But really it's just a nice thing to do, especially if someone has done something nice for you.

On the last day of school, before winter break all the grade 8 students watched a movie called "Pay It Forward" about doing random acts of kindness for people. We were given an assignment to do a random act of kindness ourselves, there were many possibilities.



For my random act of kindness I shoveled the backyard for my dad. My dad said he was going to go shovel the backyard so i offered to do it myself and he was surprised because when he asks me to do it i say that it's to cold! I told him i would do it because i had to Pay It Forward. He asked me what pay it forward was and i told him about our assignment, I said because i was shoveling then he should pay it forward somehow too and he offered me money, but i didn't take it. I told him to do something nice for someone else. I thought it was really cold outside so I dressed up really warm so I was fine. It took be about an half an hour to finish the shoveling, which isn't that long, but i still did it because my dad has done a lot!

On the last day before winter break, we watched a movie called "Pay It Forward". The movie was about a boy who wanted to help change the world, one person at a time. We were assigned to help change the world as well. I wanted to do something special, something that can put a smile on someone's face. Like make treat bags and give them to the Children's Hospital, or help at a nursing home. But, I wasn't able to do so since my parents were busy with other stuff. Although I couldn't have it my way, I realized that doing something helpful still counts.
