Marcio's Scribe

Today in class we made another Hamburger/Hotdog/whatever thingy. We covered Collecting like terms and most importantly, transposing.

Transposing is really easy once you learn.

6x + 5 = 2x +13

(From the notes)

"You transpose when there are variables on both sides of =

Move the variables to the left hand side (Letters Left)"

6x - 5 = 2x + 13
-2x +5 -2x +5

so that leaves...

4x = 18
/4 /4

then, you just do standard stuff, and your left with one variable and a number

x = 4.5 ! =D

TODAY IN CLASS

Today in class we learned about...
solving distributive properties. I'm terribly sorry about forgetting my notes at school. I am going to try my best to explain this to you.


Distributive Property
3(x+6)- two terms inside the brackets
this means 3 groups of (x+6)
(x+6)

x+6
x+6
x+6
-----------
3x+18

When you look at the question: 5(x+7), it means 5(x)=5. Then 5(7)= 35.

If you get confused, you can write it out like this: x+7
x+7
x+7
x+7
x+7
------------
5x+35
That's what we learned in class today. I don't need any help on this because I get it. So ya. If you don't get it, you can always ask harbeck for help.

Collecting Like Terms

Today in class, we talked about the magic of COLLECTING LIKE TERMS.(rainbow)

4x + 6x = 20

You would add like terms, to simplify;

4x + 6x (just add the numbers, because the variable will always be the same).

Now, with that you would cancle out, but what you do to one side, you must do to the other, So your left with one variable;

10x = 20
/10 /10
x = 2
Now, a bit harder;
5x - 3 + 4x = 24
add; 9x - 3 = 24
cancel; 9x - 3 = 24+3
/9 +3 /9
One variable left; x = 3
That's the just. Enjoy.

Collecting Like Terms


Today in class we learned how to solve like term questions. Terms that have the same variable parts are like terms.

e.g 1. 3x + 7x = 40
Add 3+7 = 10
10x / 10 = 40 / 10
x = 4
3(4) + 7(4) = 40

When solving like terms, you always want 1 variable and 1 integer term on each side.

e.g 2. 4x + 6 - 2x - 9 = 9
4x - 2x + 6 - 9 = 9
2x / 2 - 3 = 9 + 3 / 2
+3
x = 12 / 2
x = 6


And for those of you who missed class today, we created a parent quiz, which your parent/parents will take at . We will be heading down to the lab to type it into our power point presentations. In total, there will be 11 slides for math, that will show things on exponents, 1 step algebra, and its rules. They are: Isolate the variable, cancel the integer, balance, cancel what is attached to the variable, balance, and substitute to check.

The Alex Scribe

SCRIBE

Today in class we defined expression and equation and we also learned how to solve algebraic addition and subtraction questions by balancing.

An expression is a question with a variable.

An equation is a question with an equal sign.

E.G.1 X+5=10

You have to balance it.
If it's addition you turn it to a negative.
Then you add the negative to the end of the 10.
Forget the positive and negative 5's.
Focus on the question at the end.

X+5=10-5
-5

10-5=X
X=5


E.G.2 X-5=10

You have to balance it again.
Turn the negative to positive.
Add the positive 5 to the end.
Forget everything except the end.

X-5=10+5
+5

10+5=X
X=15

Solving Equations by Multiplying or Dividing

1.36w=144
w=144/36
w=4
36(4)=144

2.-7c=-112
c=-112/-7
c=16
-7(16)=-112
Divide each side by -7.

3.m/4=-8
m=-8(4)
m=-32
-32/4=-8

4.5.50t=4510
t= 4510(5.50)
t=820
5.50(820)=4510

5.5t=1375
t=1375/5
t=275
5(275)=1375

Janine's Scribe

I'll post this for Janine. Sorry it is late. There were many networking problems.

First thing we did today is: we filled out the matchmaker form for about 25 mins. Then he gave us some work to try in the overhead.
E.G1 3+x=9

x-9=14
x+3.2=6.7

Then we solved it together in the classroom.
Next we were going to learn the multiplication and division.
e.g 1
2/2 x 14/2 1} First isolate the variables.
x = 7 2} Cancel using the opposite sign.
2{7} = 14 3} Balance
4} subsitute to check




Then he assigned the class 3 pages of homework on dividing and multipliying.
After he let us do our homework pages 36 and 37. He also gave us as seperate work sheet to work on. On that page we have to do half of the multyping questions and the dividing questions.

Then finally he gave us 3 more examples so that we can understand the concept.

Lost Algebra

I created a post on the weekend all about the algebra you are doing. I am reposting it for your amusement. Please complete as much of this as you can and leave a comment behind about how you did.

Remember me Grade 8’s. Since I have been gone …only two days you must be missing me. Even if you are not missing me here are some excellent links to reinforce your learning.

The foundation to understanding algebra is to know integers. Here are two links that will reinforce what you need to know.

Try this Integer Quiz. If this is not familiar to you remember your order of operations and try again.

From this link you can see a movie on adding and subtracting integers. It is well done. If this link does not bring up the movie immediately click on the adding and subtracting integer link on the page.


Your first algebra lessons are dealing with words like term, variable, expression and equations.


Here are some helpful resources for you.
Extra help words to expressions
Extra help on variables and expressions

Here are three quizzes to see how well you did.

Substitution algebra
Solving Equations using Addition or Subtraction
Solving Equations using Division or Multiplication

Remember Leave comments to tell me how you did.

Scribes???

Being a class scribe is a serious responsibility. You need to recapture the class for that day and post it for all to see.

As Richard has said in his posts

” The purpose of a scribe is to inform the reader what your doing and by doing so you relearn what you learned that day making you just a bit more smarter. Also if the reader reads the scribe then they also relearn. To think about it. Scribing is all about learning and learning… etc.”

Try to scribe or comment daily.

Hi! I noticed that nobody has been doing the scribing lately. So i decided to help out and save Sheenqui from doing it.

1.Today in class we corrected some of the questions on the long white sheet. Then we got these two white sheets (5.2 and 6.1) We had some time to work on them in class and were supposed to finish them for tomorrow. It only takes about 10 minutes =)

2. During these activities we learned that an unknown is represented by a letter or symbol. We learned that when a number is squared you can also write it out like: (x)(x) but when your adding a number you can only write it out like this: x+x We also learned that when you see the word "is" it means equals.

3. Some of this was new information. We were only just told about it in detail but we had seen it in our math before.

4. The material was easy to understand, but only if you were paying attention.

5. I understand all of the things that we were learning today but it does get confussing when you have things like the product of 5 more than a number and 6 is thirty.

6. Well Mr.Pointon was yelling (as usual) however he managed to go through the whole class without calling me Becky once! Which is an improvment.

7. Yes there are, but Mr.Harbeck you spelt taught wrong.

hhmmm this was a hard decision to make, but its gonna be Alex. HA that's what you get for calling me Becky.

Look I'm Back

Sorry I haven’t been commenting or visiting lately. I’ve been crazy studying for exams… But now that Second Semester has started at Daniel Mac. I’m back. Hahaha. Now that I have seen that you guys are scribing. There are some excellent scribes going on and I assure you they will get better. You just have to push around each other on the blog. That’s the evolution of a blogger right there. You guys have to compete with each other to see who’s the best blogger out there. Hahahaha.

There are plenty of Examples of scribing.

Super (Secret) Scribe

Scribe or What

Scribe

Scribe Scribles

Yeah there all from the PC30S blog. Hahaha. Well you see. The purpose of a scribe is to inform the reader what your doing and by doing so you relearn what you learned that day making you just a bit more smarter. Also if the reader reads the scribe then they also relearn. To think about it. Scribing is all about learning and learning… etc.

So keep those scribes coming. And here’s a tip. Like in the examples that I posted. Try to use photos to make your scribe look even more better. Hahaha

Ricky Out.

Help the scribe

Some advise to bloggers. You need to be prepared to put a post up to the blog. People are counting on you to keep the scribe alive. If you are having difficulty post a blog and then go back in and edit the scribe.

To the scribes fellow classmates, If the scribe needs to have information added to it, post comments and add information you think will be helpful.

You all are doing a great job. I miss being at school. This is my link to you right now. Keep me informed and I will add comments if I can.

Keep scribbling.
