Today in class we looked over a few questions from our past homework. I'm going to show the questions we went over.

Pg 43.

We had a math quiz about algebra. We had 10 question and those questions are very easy. I want to share four questions with u, here is my scribe and I also show you how I solve those questions with verify.





My four questions are:




2.
2n - 9 = - 29
2n + 9 = - 29 + 9
2n = -20
2n/2 = - 20/2
n = - 10
2n - 9 = - 29
2(-10) - 9 = - 29
- 20 - 9 = - 29
- 29 = - 29




3.
- 4n + 16= 4
-4n - 16 = 4 - 16
- 4n = -12
-4n /-4 = -12/-4
n = 3
-4n +16 =4
-4(3) + 16 =4
-12 +16 =4
4 =4




5.
n/-5 +17 =-3
n/-5 -17 =-3 -17
n/-5 =-20
(-5)n/-5=-20(-5)
n =100
n/-5 +17 =-3
100/-5 +17=-3
-20 +17 =-3
-3 = -3




6.
12n +25 = -35
12n -25 = -35 -25
n = -60
12n/12 = -60/12
n =-5
12n +25 =-35
12(-5) +25 =-35
-60 +25 = -35
-35 = -35





so, those are the question I want to share with u. Isn't it easy!

Please leave your comments behind. thanks for reading my scribe.

Today in class, Mr.Harbeck went over yesterday's homework that were difficult for some people. We went over pages 43 and 44.

Today in class we went over we went over some questions from the homework yesterday. After that Mr. Harbeck told us all the questions that we were supposed to have in our multicoloured book, and here they are: on the 2 step equations part (the bottom part), on the left side, first page (additive) we were supposed to have 4 examples of your choice, (with out using algebra tiles) and on the next page on the left side still, we were supposed to have the following subtractive questions: 7x-2=61, and -8t-23=-15. On the next page after that, the multiplicative page we needed to have these questions: -n+4=-2, and 3n+5=55. On the equations side (the right side) we needed to draw these in algebra tiles: the additive page, 2x+3=9, and -2x+4=10. On the subtactive equations page we needed to have 2x-6=4, and -2x-3=9. On the multiplicative equations page we needed to have 2n+1=5. We also did alot of examples on the board, they were mostly divisive, but we did do one multiplicative review question with algebra tiles, which has already been done in previous scribes.


Today we learned all about how to do divisive 2 step equations. All the divisive questions that we did were supposed to go into our multicolored book. We did five questions in class without algebra tiles but I am just going to show you how to do 2 of them.

The first question that I will show you how to do is n/4+3=15.

(Here's a hint: always remember that the variable gets canceled 2ND!)

Here is the other question that we did, this one is a bit trickier, 1/4n+3=8


(Here is another hint that might help: just remember, fractions are division!)

-1/4 times a number.
-Think 1n/4, draw n/4.



-When you substitute, you substitute for n.

That was basically all that we did in class today, a few divisive examples, but we do have homework, it is to finish the rest of page 43, and the first 6 questions on page 44 from the purple book, and I don't think that you need to draw algebra tiles for these ones. We also have a quiz on Friday on 2 step equations.


For tomorrow's scribe I pick Melanie, because she was supposed to do it today anyways!

Please comment and tell me ANYTHING that I can change!

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.

Today in class we started on the 2 step equations.
On the inside of the blue, we wrote 2n+1=5.

You isolate the variable (2n)
Cancel constant (+1)
Balance
Cancel multiply (2n)
Balance
VERIFY

There are 2 cancellations.

You cancel the constant first. You get rid of the +1 with a -1.

2n+1=5
-1 -1
2n=4

You get rid of the variable second. You get rid of the times 2 with a divide by 2. n=2 After that, you verify.

-2n+1=5
-2(2)+1=5
4+1=5
-5=5

You don't need all 4 lines. Only the parts in blue.

After that, we went on to the next page on the front. We wrote 3n+4=19. We solved it 2 ways. The first way was the same with the last question. The other way, we just did the cancelling on the other side.

3n+4=19-4/3
n=15/3
n=5

The verifying is the same as the other way. After that, we switched to the 'equations' side (the front-right-bottom side) of the green where you draw the pictures. This is what we wrote.

After that, we went to the back of the bottom-left green part and solved -2n+3=9 both ways. We went back to the other part of green (the bottom-right-back) and drew this.

Our homework was in the purple booklet. Page 43, the multiplying questions only. I choose Zerlina to do the next scribe.

For today I was told to do a scribe about yesterdays test here is some of the questions that were on it.

Before winter break we've watched the movie "Pay it Forward".There's a task that we have to do and that is to do something that you can to pay it forward.In the movie there was a boy that believe that one person can make big difference.In this assignment we have to do any act of kindness.In order to solve that we have a couple of questions that we have to answer:



1.Who are you going help?
2.What are you going to do?
3.When are you going to do this?

During i the winter break i choose to... well i didn't really think of anything. So i had to find one. Well i found out my cousin was coming here to my house. So i figured i would babysit. Well it was the perfect time because my auntie was going to leave my cousin here because she had to go to work. But my mom had to go somewhere.Well i volunteered to do it and she said yes. So she left my little cousin here. It was pretty easy because he was already 5 and he was really fun , like we played video games and ate because my mom left some food for us to eat in case we get hungry. When my mom came back from the groceries there was a big mess, well me and my cousin cleaned it up when they came. When they came my parents took care of them because i had to go. it was really fun helping my aunt and babysitting my little cousin. I was really happy at the end.

The question was if ONE PERSON CAN MAKE A DIFFERENCE to my the answer is yes, anyone can make a difference no matter who you are, so start helping anyone out there who needs help!

Today in class we went over are homework that we got on Friday all 50 questions in the pink booklet. Then we got 10 more questions for homework and sorry thats all that I can remember.
these are some of the questions that we got for homework
1: -30n=180
2: -n/3=6
3: n-6=14
4: 25=-12+n
sorry I have no time to put on the answers and good luck on the test.

Today in class we went over our Math homework from the pink thingy he gave us. After doing all of those stuff he gave us a homework to practice for our test/quiz tomorrow. i will list all of them and i will answer four of them.

here are all of them :

1) N-6 = 14


2) N+9 = -4


3) - 9 + n = 17


4) 25 = - 12 + n


5) N - (-6) = 15


6) -N/3 = 6


7) -30 N = 120


8) 1/4 N = 12


9) - 1/3 n = 10


10) 12 N = 48



the questions with the slash in them are suppose to be horizontal because it's being divided by.

Here are the Four that i will answer

Here is my first one


n+9=-4

n+9-9=-4-9

n=-13

n+9=-4

13+9=-4

-4=-4


Here is my second one


25 = -12+n

-12+12+n=25+12

n=37

-12+n=25

12+37 = 25

25 = 25


Here is my third one

9+n=17

-9+9+n=17+9

n=26

-9+n= -17

-9+26= -17

17=17


And here is my Last one


n - 6 = 14

n [-6 + 6] = 14 + 6

n = 20

n – 6 = 14

20 - 6 = 14

14 = 14


Everything i answered might be wrong so just comment. Be ready for the test tomorrow study, these scribe might help so read it. And that's about it . For the next scribe i choose no one yet because i dont know who didn't do it yet . Or am i suppose to choose anyone? Anyways study and comment please!!!

Before winter break the teacher made us watch a movie its called Pay It Forward.
And we watch it and there was boy who believed that one Person can make a difference.
And they gave us home work question.


1). Who are you going to help?
2). What are you going to do?
3). When are you going to do this?
4). When are going to do this?

During the break I went outside and I shovel the snow.It was cold and my hands was frozen so i went inside my mom made soup so i can get warm.I shovel in front and back of the house and outside of our garaged.I did this for 1 week.My Sister help my mom doing washing cloths and more stuff. My dad was listening no music,and I help burn a CD,I put music old music.

Then the question we need to answer is CAN ONE PERSON MAKE A DIFFERENES
and my answer is yes.

Today in class we went over our questions from the pink booklet. We had to do 50 questions before the week end was over. After we went through the ones that were tough we got our home work to practice for out test tomorrow. We had 10 questions I am going to list 4.

Before winter break we've watched the movie "Pay it Forward".There's a task that we have to do and that is to do something that you can say pay it forward.In the movie there was a boy that believe that one person can make big difference.In this assignment we have to have act of kindness.In order to solve that we have some couple of question that we have to answer:



1.Who are you going help?
2.What are you going to do?
3.When are you going to do this?

During the break i want to give my family a little help.For the first time i will woke up 5:30 even though i've sleep in 2:00 in the morning.I will do lots of things in our house to pay my parents forward for what they do to us every day.I've started in 5:40 and clean up the living room and the washroom. Then 8:00 i was the dishes and make our breakfast.Ive wash the dishes once again and take a bath because have a practice in 11:00 to 12:30.After my mom picked me in school i shovel snow and clean our car.I'm kind a tired and i started to sleep but i have to do somethingelse to help my parents but my mom said thank you.And i was like so sleepy and i fall down on the bed and started to rest.I enjoyed time doing those things.I feel great that i do a little help for my parents.Showing kindness can really make a Big difference.

Today in class we did fill out our yellow barn door.Mr Harbeck give as some question and we try to answer it in Algebra tiles.




Here are some example of what we did today:


2n = 10
2n=10


2n = 10
2 2

n = 5

2n = 10

2 (5)= 10

10=10

Using Algebra Tiles

2n = 10













Sorry for the Mistakes")
For the next scribe i choose Sebastian

Before winter vacation we watch a movie " Pay it Forwad " . In winter vacation many immigrants came here and some from my country. In beside my house there are one family came from a muslim family just like me and they want help to know about this country and the buses time table that they can travel by bus. So I decided to help them. I told my mom can I help them than my mom said " yes! you can " so I go for visit their house and I saw a girl just like me I mean same age and I help her for admission in Canada's school and help her parents too and in some days I get a really good friend like her and such a nice family fot pass my leisure time. It just like that story I see " Pay It Forward ". In that movie a girls help another girl to know something special. I help the girl to know the country and the people and I won her friendship and she is a really good student too, we always help other for study about something and made so many plans that we want to do that summer and my mom and her mom also get friend. Oh! I forgot to tell her name, her name is mouli and she is from my country too. now she tell me first I fill really a outsider! but now I am fill very good to have a friend like u and I told her me too!
I just tell myself some question
why her family don't want to stay here?
Is that Bangladesh is better than Canada?
Is that Canada is better than Bangladesh?
Is that good for our future to stay here?

Today in class, watch a movie about Additive Equation and Subtractive Equation.
Then Mr. Harbeck answering the question from homework yesterday by using the Algebra tiles for Additive and Subtractive Equation.Mr.Harbeck give some assignment about the Algebra Equation solving.

Right now disscused the part of Algebra Equation Solving like a Additive Equation.

Here are some Example for Additive Equation:












After disscused the Additive Equation now is Subtractive Equation. The subtractive Equation is the same step of the Additive Equation.


Here are some example of Subtractive Equation:












Sorry for the mistakes!!!
For the next Scribe I pick Gerico Lacap.

Before the winter break we watched a movie entittled "Pay it Forward". In the movie there was a boy who believed that that just one person can make a big difference. We have a assignment that we have to act kindness. And we have answer this questions.

1). Who are you going to help?
2). What are you going to do?
3). When are you going to do this?
4). When ar going to do this?


During the break my aunt needed someone to take care of her kids because she to go to work and their babysitter can't come. I volunteered to look after them. I played with them, helped them with their needs, prepared their food and did a little house cleaning.

I enjoyed my time with them. I felt great with what I did.I can say doing things, even simple things, showing kindness and giving help could really make a difference.

Today in class Mr. Harbeck went over the homework we had to do on pg.41in our purple booklet.
Then Mr. Harbeck showed us how to use algebra tiles to answer additive and subtractive questions. Next he wrote some questions down for us to do in our colorful booklet.
What are algebra tiles.
Algebra tiles are things you draw to show how you explained it instead of just answering it.

Here are some.
Now Mr. Harbeck showed us how to use Algebra tiles with a Additive equation and Subtractive.
I will be showing you a picture later but now I am going to tell you the steps first.

In a equation the rectangle is N,so don't put in the sign and the cubes are regular numbers.

Additive Example:
After you have drawn the Algebra tiles for N+3=5, you now add the negative cubes.
( ones with arrows). (Which is 3, because you add the opposite of + which is - )
Then you circle the zero pairs (red and white cubes) and put a x through them.
I didn't because its a picture but you can if you are writing it.
Now they are nothing.
Next you only have the rectangle and the = sign on the left and+2 on the right.
After that you combine them both so its reads rectangle = 2 positive cubes. N=2
Now here is a picture of what I just said


Subtractive Example:
After you have drawn the Algebra tiles for -3+N=7, you now add the positive cubes.
( ones with arrows). (Which is 3, because you add the opposite of - which is +)
Then you circle the zero pairs (white and red cubes) and put a x through them.
I didn't because its a picture, but you can if you are writing it.
Now they are nothing.
Next you only have the rectangle and the = sign on the left and +4 on the right.
After that you combine them both so its reads rectangle = 4 negative cubes. N=4
Now here is a picture of what I just said

I pick Justin.A for the next Scribe. Please comment

In class we watched a movie about a kid who believed that he can make a diffrence, he thought of a plan that could change the world, his plan is to help people who needs help then those people need to help other people, you get the idea. That movie is entitled Pay it Forward. This movie is an inspiration for all of us and i wish all people would follow this example.

During the holidays we were ask to show kindness and to help people who needs help. This holiday I help many people but its hard to keep record every time so i choose the top 2

This was the first image. at this time im helping my mom fold the towels














this is the second picture. at this time Im the one who is wiping the table.














When I did this kind of stuff it kind of makes me feel good because you can make someone happy.
But the question is CAN ONE PERSON MAKE A DIFFERENCE? the truth is yes, any one can make a difference it doesnt have to be something big as long as you help someone you can make him or her happy

Before the winter break, we watched a movie called "Pay it Forward." The movie was about someone who believes that one person can make a difference. After watching this movie we were ask to do a random act of kindness and ask who ever we helped to Pay it Forward. What I did to pay it forward was I shovel snow and cleaned around the house(wash dishes, clean my room, etc).
I helped my parents do all that stuff after New Year.
I felt really good that I helped out my parents. I think my parents were happy that I helped so that they wouldn't do as much work around the house and get tired. I think one person can really make a difference just by do something to help another.

Today in class, we made a colorful booklet or a barn or booklet thingy. The colorful booklet's cover is blue so in case it gets lost people could easily recognize that the booklet belongs to someone from the room 8-73. Mr. Harbeck also gave us a purple booklet full of Algebra questions.

In class we watched the movie "Pay it Forward", it is about a person that believes that just one person can make a difference. After watching the movie, we were asked to do a random act of kindness over the holiday's and ask them to "Pay it Forward". I was thingking about shoveling so two days before new year me and Andrew chose to go to my friends house. then me and Andrew started acting out some kindness by shoveling our friends yard. Like Andrew said it was cold that day but me and Andrew still chose to Pay it Forward.












1) Who are you going to help?
2) What are you going to do?
3) Where are you going to do this?
4) When are you going to do this?


I felt happy that I helped my friend shovel his yard. So you ask if one person can make a difference, my answer is yes! it doesn't have to big as long as you do something good and it makes the person happy and might even do it for someone else.

Before winter vacation we had watched a movie called "Pay it forward", which is about a boy who had a social studies assignment to change the world by helping people then telling them just to pay it forward. Our assignment was to do an act of kindness. Here are the questions.
1) Who are you going to help?
2) What are you going to do?
3) Where are you going to do this?
4) When are you going to do this?


This winter the task I chose is to put up most of the decorations inside and even outside my house. On the day before Christmas Eve my dad and me had went to buy new Christmas light for the front yard and some Christmas tree decorations. When we got home the first thing i did was to check if all the lights worked and put them up. By the time i had finished i started Putin up the tree and putting on the decorations.
Here's a picture.

( picture is not uploading ) ill try to get it up tomorrow.

Then from there I told my dad to pay it forward and he helped my neighbour put up some of there lights and then after new years my dad told me half of my street got " payed forward " and it had started with just 1 person. When he told me i got very surprised and I felt good inside.

The Question we had to answer was can one person make a difference?
I think 1 person can make a difference from the experience i had this winter made me thing alot about this question so yes one person can make a difference.
Happy new years .

We watched a movie called "pay it forward" at school, its about a person making someones life.
