Hello I am today's scribe

The first fifteen minutes of class we corrected some questions from page 43 and 44
.


After that we learned how to do word problems. It's the first one on page 46.

Example One

1. Ken is thinking of a number. Nine more than the product of 4 and the number is 73. Fine Ken's number?

Ken's number is _______.

*For word problem you always have to write one simple sentence to get the mark.)


First you have to fine the constant
n = 73
next you have put the 4 by the n
4n =73

And then you add the 9
4n + 9 = 73
AND WE ARE FINISHED THE FIRST PROBLEM..... YEEYAAAH....!!!!! :)

Remember there is a TEST tomorrow and it's based on your homeworks you've done this week.... and your homework for today is to finish page 43, 44. Plus you have to do page 45 (ONLY THE EQUATIONS).

and from page 46 you have to do any 4 PROBLEMS....

and the next scribe is Spiderman.... just kidding.. or the next scribe can be Mickey Mouse... jokes never mind the real next scribe is Casey.. GOOD LUCK ON IT....( Jordan says hi to everyone and me too) Hope you enjoyed my scribe!!! :)

Today we looked at Subtractive and Multiplicative Two-Step equations. So remember, isolate, cancel using the opposite, balance, cancel using the opposite, and verify. Also, Pizza(the constant), hides in the closet, and gets caught first, then chicken wing (the variable), hides in the bed, and gets caught second. Also, the proper way to use the shortcut is: 
Oh, yeah, and I forgot to show it here, but you need to verify also. For the next scribble I choose Ben, unless he already did one.

Today in class, Mr.Harbeck gave us a white worksheet to complete. We had to pick two questions for part 1 & 2, and do every question for 3, 4,5. We had to draw algebra tiles to solve the equations. Then add and make sure you read the questions carefully because they don't all ask you to draw algebra tiles, but you do need to VERIFY!

1. Draw balance scales and blocks to represent each equation.



2. Draw algebra tiles to model each equation.



3. Solve each equation.

4. Show whether x=6 is the solution to each equation.

HEEEEEELLLLLLO!
Today, in class we went over a couple of questions from the weekend's homework. We've been given ten more questions to do for homework today. I've been asked to do any four of those questions.

The first question I choosed was, n-6=14. So first, I isolated the variable. Since there was a -6, I put a +6, and since I did it to the left side, I must do it on the right side. -6 and +6 cancel eachother out, so we get n. And on the right side, 14 and +6 = 20 so, the equation is now n=20. We have to verify, so first, write the original question down, n-6=14 and then instead of putting n, write down what n equaled to. 20-6=14, both of them equal 14, so then at last, put 14=14.
The second question I chose was 12n=48.

Okay, I'm going to simply draw the steps since I pretty much explained it to you already on the first question that I chose.

The third question I chose was n+9=-4.

And the last question I chose was -9+n=17
Okay, so I've explained to you how to Isolate, Cancel Out, Balance, and Verify. I've taken pictures for you to see my examples. I think I'm pretty much done. OH! AND! I found out from Maeddah that there are three test questions that Mr.Harbeck posted in the comments on his stuff that he posted today. I'm sorry if you don't get to see this. I know I'm doing this really late. It's actually 11:11 now. LOL! Well, I guess your wondering, who is the next scribe? Umm... Hmm... I pick...Aleksander Schuman. I just picked a random person off of the scribe list. Well, tata for now ! :)

Hello classmates from 8-41 ! (: Well, today I'm the scribe. Anyways. today in class we corrected the homework from yesterday. It`s the ones from the barn door booklet. Here are some of the questions.


Here are the steps for solving an algebraic equation:

First, you must isolate the variable.
Second, you must cancel by using the opposite.
Third, you must balance so the other side is the same as the other.
Finally, you must verify (substitute).
















Here's another one.























There`s more questions but I just pick 2. One`s an additive and the other`s subtractive equation. :) After correcting the questions, Mr. Harbeck gave us homework. Talking about homework, we have to answer these questions before 9:00 o`clock TOMORROW!






I hope you guys liked my scribe! (; If you see any mistakes, please comment on this, thank you! :) Now for the next scribe I choose is...........................................CARRIE ! :P HAHA, good luck !

Hello classmates from 8-41! (: Today I'm the scribe, HAHAHA! Anyways, today in class we started learning the words variable, constant, and terms. We also did work on simplifying expressions or equations, regrouping them, and circling the like terms.

This is what we did....

Variable:
- A letter that represents a number.
-examples: y,n,t

Constant:
-The integer in the question.
-examples: +9-6

Terms:
-parts of the expression or equation.
examples: 3n +6

What we did next:

We simplify by collecting like terms
or
what Mr. Harbeck would say " Let's go shopping!"

These were examples of expressions and or equations we did with Mr. Harbeck:






Homework: Pink booklet, page 6 and page 22. (:

I hope you guys liked my scribe! If you see any mistakes, please tell me by leaving a comment behind, thank you! (: Now for the next scribe I choose..........................JAYZIE! (: HAHA, good luck!

Hello EVERYONE! Today we did numbers 1, 5, 6, 7, and 10 on part B.

QUESTION 1:

Question 5:
Question 6:

Question 7:
Question 7:

Here's some extra things I decided to write down while Mr. Harbeck was talking:
  • x's in algebra have to be in handwriting or it will look like multiplying
  • < = is less than . Must be all together. Can't be " is 7 less than "
  • If you see commas in algebra you just leave it.
HOMEWORK:
  • Pink booklet Part C # 1 - 24.
  • Finish Integer Poems by FRIDAY.
Please comment if I have any mistakes and I will fix them up as soon as possible. Now, the NEXT scribe I choose is ..................... ARIELLE SAY-YOU-KNOW! Good Luck! And be happy that I chose you because you have the whole weekend :)

Today in Math Class we started ALGEBRA.
We started the unit of by thinking of ALGEBRA WORDS: ADDING, SUBTRACTING, MULTIPLYING, DIVIDING, &
EQUALS.
ADDING
n+6
-increase by
-combine with
-plus
-and
-add
-gains
SUBTRACTING
n-6
-subtract
-minus
-takeaway
-diminished by
MULTIPLYING
3n (means: n+n+n)
-three times a number
DIVIDING
n/3
-means a number divided by three
EQUALS
n+6=8
-equals
-gives you
-is
-makes
-results in


We also learned the difference between algebraic expressions and algebraic equations.
algebraic expression: --> pattern
n+6
- number plus six
- there are many possible answers.
What is n?
- n is a variable
What is a variable?
- a variable is a letter that represents a number
algebraic equation:
n+6=8
-a number and six equals eight
-there is only one possible answer
Well, i'm done my scribepost. I hope you liked it! I liked it because it was very colorful :) For tomorrow's scribe, I choose MICHELLE! HAHAH :D Have fun Michelle.
