--------SCRIBE--------

What do we do in class today?

---We did some warm up questions about the sphere thingy but i dont get it..
but maybe tomorrow...and we also answer the yellow sheet, the adding and subtracting integers...and about the balance thingy..

What did we learn during these activities?

---We learn about mulipying integers..and we talked about the adding and subtracting integers
we learned that when the brackets are KISSING they are multipying and just multiply normally....and first count the negative signs...
EXAMPLE: (-4)(-4) =16
even amount=+ odd amount= -

Was this new information or something I've seen in math or another class before?

---i think some of the words...because some of them like the have and owe thingy? i just heard it here...and now..i understand oue lessons...:)

Was the material difficult or easy to understand?

---some of them are easy like the adding and subrtacting integers..but the sphere thingy..i dont get it....

Is there something that I still don't understand and could ask my classmates to explain?

---i think yes..i'll just ask them tomorrow..:P

Did anything else happen during class that would be fun to keep a record of?

---yes..the yellow sheet thingy...for me...atleast you try to solve the questions there..

Are there any links out there to explain the concepts taught in class?

---i think yes?.....hehehe....

The next scribe would be mharjoy:)

..SCRIBE :)

Scribe from Mr. Harbeck and then he passed it to Norielle and then Norielle pass it to me >=( j/k

1.What did we do in class today?
--Today in the class we did some corrections in adding and subtracting integers and we did some of it. After that, we did the cylinder, sphere thingy.. its hard but then now i get it. And then we started in multiplying integers. and with the brackets signs ( ) [] . Thats all we did today..!

2. What did we learn during these activities?
-- I learn how to solve the following algebra problems in easier way because last year we did it in a long way.

3. Was this new information or something I've seen in math or another class before?
-- Yes, I've seen it in math class just last year.

4. Was the material difficult or easy to understand?
--Its kinda creepy but then I do understand those things easily.

ScriBE...

It says there that as a scribe i have to answer the following Questions!!!

1.What did we do in class today?
Today in class we did some review about adding integers and we did some warm up questions...after that we checked some questions from our homework...Then MR.HARBECK taught us about adding and subtracting integers in the ORder of Operation...he give us some rules ...but then i forgot my notes in my locker so yeah...but as long as i remember...first you have to the do the questions from the brackets...then copy the operation..then do the one in the [ ]. So yeah that's all we did in our class today...

Example:

--->3(-3-7)+(10-4)

--->3-10+6

--->-7+6

answer: -1



2. What did we learn during these activities?
i guess that the activities that are mention in the question are the activities in yellow sheet..i guess i learn HOW TO ADD AND SUBTRACT INTEGERS IN STANDARD FORM...AND HOW TO ADD AND SUBTRACT DOING THE ORDER OF OPERATION...


3. Was this new information or something I've seen in math or another class before?
I've learn some of this information from our class last year...

4. Was the material difficult or easy to understand?
For me it was easy to understand...

5. Is there something that I still don't understand and could ask my classmates to explain?
i Guess there are still something that i don't i understand but then its hard to ask because i didn't find the question yet..i think..

6. Did anything else happen during class that would be fun to keep a record of?
Except for the lessons... iguess none...

Are there any links out there to explain the concepts taught in class?
i dont know...maybe...i guess...

Time To Scribe

Scribes in Mesopotamia used a stylus and clay tablet to keep track of may things. If you are the blog scribe you are to do the same for math class.

So... when it's your turn to be scribe, try answering these questions in your blog:

What did we do in class today?
What did we learn during these activities?
Was this new information or something I've seen in math or another class before?
Was the material difficult or easy to understand?
Is there something that I still don't understand and could ask my classmates to explain?
Did anything else happen during class that would be fun to keep a record of?
Are there any links out there to explain the concepts taught in class?

When you are done your post please pick another student to be tomorrows scribe.
Make this a fun assignment.

How much effort you put in it is up to you.

11. underline the question in the problem.

2. read it over and make sure you know what you are being asked.

3.create a simple sentence and answer it with a blank.

4.make a word ratio with part over whole.

5.fill in all of the information that u can. then cross multiply.

6.check your answer and make sure you have all of the right parts. and use all of the correct units in your answer.

2 . what percent is 56 pounds of 140? 56 is the part and 140 is the whole. 56 over 140. ? over 100%. then i cross multiplied. 56 multiplied by 100 divided by 140=40. 56 pounds is 40% of 140 pounds.

3 the area of the door when it was doubled question. i got that wrong because i did not double it width wise. the answer is actually 32. 8x4=32.

4 i understand i'm supposed to ask fer help. but i cant think of anything i need help on. but thanks anyway.

5 i like how jemimah has been doing her blogs, they're very organized. keep up the great work.

there, i'm done the blog.

...

1.
1)write a simple sentence answer
2)underline the information you were given and think about what it's telling you to do
3)make a word ratio
4)do the cross multiply method to find your answer
5)check back to see if your answers are correct

2.
#3 The original price of the sofa was $500. It is now on sale for $440. What was the percent of decrease?
Answer: The percent of the decrease is ___%
P = DISCOUNT = $60 = ___%
W = REGULAR $ = $500 = 100%

600 x 20 = 12,000 / 100 = 12
So:
The percent of the decrease is 12%

3.
#9B If you enlarged the original diagram to twice its size, what would be the area of the door?

My mistake: THE AREA WOULD BE ___ SQUARE CENTIMETRES.
P = NEW AREA = ____= 200%
W = OLD AREA = 8 = 100%
8 x 200 = 1600 / 100 = 16

Correct answer: The are would be 32 square centimetres.
width x length = new area
or
4 x 8 = 32

P.S. If something is wrong in this post please leave a comment and tell me how to do it properly and if there is any other solutions if you could please share it with me. Thank You

QUIZ QUESTIONS
1.The steps needed in successfully solving % problems are:
-write a simple sentence answer
-look at the information you were given and think about what the question is asking you
-make a word ratio with part/whole
-make a fraction and cross multiply to find your answer
-make sure to include your unit of measurment in your answer
2.A question i got correct on my quiz was number 2.
56 pounds is____% of 140 pounds.
part pounds 56 40% 56x100
whole = pounds 140 = 100% 140 = 40
56 pounds is 40% of 140.

3.A question I got wrong was number 8.
I wrote- cards given away 280 46 2/3 280 x 100
all cards 600 = 100% 600 = 46 2/3
My mistake was forgetting to subtract my answer from 100.
The answer should be 100-46 2/3=53 1/3

Thanks for reading!

My Quiz Blog by ANON

1. To successfully do percent problems you need to know the following:

1. What is the question.
2. Answer the question using a simple sentence answer (using a blank for an answer)
3. What is the part and the whole? Create a word ratio.
4. Set up a proportion that looks like this part/whole = %/100%
5. The last step is to ask myself does my answer look right? If it does I can use the cross products to check if my answer is correct!

Correct Question
On an aritmetic test John received a grade of 80% He solved 24 problems correctly. How many questions were there on test?

John's test was out of __________.

On an aritmetic test John received a grade of 80% (The percent) He solved 24 problems correctly(The part because it is not the complete test!!). How many questions were there on test?

The word ratio is
questions correct/total questions
24/? = 80%/100 b therefore 24 x 100/80 = 30
There are 30 questions on the test. (30 x 80 = 24 x 100)



A question I got wrong was
The original price of the sofa was $500 It is now on sale for $440. What was the percent decrease?

The percent decrease was _______.

The original price of the sofa was $500(The whole) It is now on sale for $440(The Part). What was the percent decrease (The UNKOWN)?

sale price/origional price = percent of sale $ /100% 440/500 =88%/100%

My Mistake was to say the 88% was the percent decrease. I needed to subtract the 88 from 100 to get a difference of 12%. There fore the percent decrease between the sale and origional price is 12%.

This is an example of what your post can look like. Please restrict your use of colour to one and its use is to show important ideas inside your post.

Work hard and make this post work. Comment on other peoples work. If they are confused and cannot answer their question show them how. We all must work as a community.

Post away.

Answer for Lucky 13 assignment!!

1) The problem solving techniques that you were teaching is first highlight the question that needs to be answered in the problem. Then make a simple sentence and creat a word ratio and finally answer it.
2)Haley has enlarged a 3" by 5" picture so that both the length and the width are tripled. By what number must the original area of the picture be multiplied to get the enlarged area?
The original area must be multiplied by_____.
1st multiply 3 by 5: 3 x 5 = 15 <----- area of the original picture
Since the sides are tripled multiply each of them by 3:
3 x 3 = 9
5 x 3 = 15
Multiply 9 by 15: 9 x 15 = 135
then divide the answer by the original area.
135 / 15 = 9
So now you will put it in the simple sentence.
The original area must be multiplied by 9.

There are___girls than boys are in the class.

P = G = n = 75
W= ts= 35 = 100

Note: 3/4 is same as 75 but out of 100

35 x 75 = 26.25
100

n=26.25

35
-26.25
8.75 round it off so it going to be 9

so, There are 9 girls than boys are in the class.

this question is quite hard...but i try...

1) a) The difference between discount and sale price is that discount is the amount of money you subtract from the regular price and the sale price is the total amount.
b) This is how you caculate these 2 amounts:

50% of 200

change the 50% into a decimal and multiply it by 200
which looks like this:

.50x200= 100

2) a) 50% of 70

70/2 equals 35 so the answer is 35

so therefore 50% of 70 = 35

b) 35% of 80

change the percent into a decimal

0.35x80 = 28

just do it on a caculator or in your head it's easy!

1. Question what is the difference between Discount and Sale Price? How do you calculate these two amounts?

Discount is amount subtract from the cost or the price while Sale Price is the total amount

to calculate a discount:
example: 25% of 40

2 ways:

1. using a calculator: .25 x 40 = 10
2. using a mental percent:
100% = 40 divide it by 4 to get 25%
25% = 10

2. How do you calculate mentally percetages without going insane. What is 50% of 70?What is 35% of 80?

To calculate mental percent:
example:
a) 50% of 70

100%=70 divide it by 2 to get 50% or half
50%=35

so, 50% of 70 is 35

b) 35% of 80

100% = 80 ......look for an easier way to get 35%
get 25% first then add 10% so...
25%=20
+10%=8
35%=28

so, 35% of 80 is 28

1. Sami decided to park her car at Park&Go for her four-day trip. The cost is usually$8 per day or partial day. However, Sami has a 20% discount coupon for her entirebill. How much did Sami’s parking cost?

Answer:
$8 x 4 =32 <-- total payment

Discount: 20% of 32 to get 20 % of 32:
100% = 32
10%=3.2
+10%=3.2
20%=6.4
so you have to subtract 20% of 32 from the total parking fee:
100%=32
- 20%= 6.4
25.6

So, Sami's parking cost is $25.60




Français/French Deutsch/German Italiano/Italian Português/Portuguese Español/Spanish 日本語/Japanese 한국어/Korean 中文(简体)/Chinese Simplified Tagalog/Filipino

Answer for You call this homework! (just bored so i did it anywayz)

Discount is the amount that gets subtracted from the regular price. Sale price is like the regular price but minus the discount.

Example
If a $100.00 jacket had a 50% discount, then you would multiply 0.5 by 100.

So 0.5 x 100 = 50

$50.00 is your discount. Then you would subtract the discount price from the regular price.

$100 - $50 = $50

So then you would have to pay $50.00 which is the sale price.
__________________________________________________________

50% of 70 = 35
Just divide 70 by 2, because 50% is also known as 1/2.

35% of 80 = 28

100 = 80

10 = 8
10 = 8
10 = 8
5 = 4
+ ____
35 = 28

Respect in the classroom

I have heard many replies to my past "adventures" on the blog referring to math and noodles. I am issusing a deep apology for my actions on the day of January 10, 2006. I was foolish, and am deeply sorry to the math nerds that I've disrespected. Forgive me for what I have said, but I still stand by my past comment, and are a stiff believer of math being unamusing, but alas, it was no way to act. My people are ashamed.

When you enter your blog space create a post that answers any questions that are being asked. I will post one every week. If you are the class scribe you need to tell the class what happened in class that day
-what concepts were being taught
-give examples to help explain what was going on.
-find links to sites that are helpful to your math understanding.

You can read your classes blogs and leave comments so that they can get help from you.

Remember this is a public space and an extention of the classroom. Act and write appropriately.
