January 11th's Scribe

Today we worked in our blue book, we went over our homework pages 31 and 32. Our homework was to do the first three squares on page 33. We needed to find out the rest of the square. The first square was 1/4 then 2/3 then 1/5.

We also did two questions about portions/fractions/problem solving.

The first question was about a girl saving money.
Every time she would make a dollar she would save 23 cents of it.
The question asked how much would she save if she made $75 in a week.
So you would have to put your anwser in a line like...... Saved/Earned=0.28/1.00= ?/$75
You could cross mulitply- 75x.28=21/1.00=21
You could divide and mulitply- 1.00/75.00=75
1x75=75
.28x75=21
So it would be Saved=0.28=$21.00
Earned=1.00=$75.00
The second question was about running and time.
When you run 4 laps it would take 18 minutes.
The question was how many laps could you do in 1 and a half hours.
So you would have to put anwser in a line like........Laps/Time=4/18=?/1.5
You first need to find out the 1.5 time which would be 90 minutes.
You could cross multiply-90x4=360
360/18=20
You could divide and multiply- 90/18=5
5x4=20
So it would be laps=4=20
time=18=90(1.5 hours)
That is what we did and what I remembered.
The next scribe willlll beeeeee........... James G.

Scribe Post Jan. 9

Hi. This is my first scribe post, so there's a good chance it'll be terrible. Here goes.

TODAY
We had the Harbeck double-whammy. I get to cover part 2.

We started off with a bit more of the blue booklet. The number lines, page 32. It's pretty much self-explanatory. If you follow the instructions, you should get it quite easily.

After that, Harbeck handed out some question booklets to some people, and the rest had to read it off the overhead. The questions that Harbeck assigned were:

1. Seven of a baseball player's first 28 hits were triples. The baseball player had a total of 140 hits.

If the baseball player maintainted his rate of hitting triples, how many triples did this baseball player hit in all?

{A. 7}     {B. 14}     {C. 28}     {D. 35[]}

_____________________________________________


2. Alabama has 21, 653, 000 acres of forests and a total land area of 32, 480, 000 acres.

If a 210-acre farm has the same ratio of forested land to total land area, approximately how many acres of the farm will be forested?

{A. 140[]}     {B. 160}     {C. 180}     {D. 210}

_____________________________________________


Yep, Harbeck made a mistake. There's a box beside the right answer for every question in the booklet. But what Harbeck wants to know is how you get the answer.
AND REMEMBER:

1. WORD RATIO
2. PART
     WHOLE
3. LINE UP ALL INFO,
AND USE EQUIVALENT FRACTIONS.


If there's anybody left who hasn't done "the scribble", it's their turn. *coughcoughbrandoncoughcough*

HAVE A NICE DAY.

Yesterday in class we did the problem of the week and reveiwed the percents...
1. What is 35% of 90? 31.5?90 is equal to 35/100 90 divided by 100= 0.9/1= 31.5/35
2. what percent of 40 is 25? 25/40 is equal to 62.5/100 25 divided by 40 is equal to 0.625/1= 62.5/100
3. 33 is 10% of what number? 33/330 is equal to 10/100 33 didvided by 10 is equal to 3.3/1 which equals to 330/100
Then we did the first page of the blue booklet for homework.
Today we reveiwed the first page of answers for the first page of the blue booklet. For homework the second of the blue booklet due tommorow.

And whoever hasnt done scribe is the next scribe or if there is noone else than its whoever wants to go!

Earl's Scribe (January 8th, 2007)

Todays notes that Mr. H told us to write are the following:

Percent

-out of 100
-/100

Answer the following questions:
Questions:

1. What is 35% of 90?
2. What % of 40 is 25?
3. 33 is 10% of what number.

Answers:

1. 31.5/90= 35/100
90 divided by 40= 0.9/1= 31.5/35

2. 25/40= 62.5/100
25 divided by 40= 0.625= 62.5/100

3.33/100=10/100
This is the way you get the answer: 33 x 10= 330
and 10 x 10= 100

The following is the homework:

For homework we had to do the first page of the blue booklet. The questions are the following:
Questions:

A.Shade in 1/2 of the square at least six ways.

B.Shade in 1/3 of the rectangle at least six ways.

C.Determine what fraction of each flag is shaded.

James G's Percentage Growing Post (Question 6)

Question 6
Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.

a) 16 is 40% of what number?
40/40=1%
40/100=0.4
0.4x100=40
40/100 = 16/40

b)
What is 120% of 30?
120/120=1%
120/100=1.2
100=30
1.2x30=36
120/100 = 36/30

Earl's Growing Post

1.What is a good definition of percent? You should use words symbols, pictures and numerical examples in your definition.
A percent is a fraction out of one hundred. This is the percent sign %. Mr. H said it means 100 in French. For example 23/100 is 23%.

2.How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show your answer.
They are all the same because if you change them all into percents they will all be the same thing but in percents. For example if you had 3:2 and 3/5 if you change then 3:2 into a fraction guess what the fraction will be. If you said 3/5 you are right.Then another example is if you take 60% and 0.6 and change the decimal into a percent guess what it is. If you guessed it would be 60% you are right.

3.Show 3 different ways to find 35% of 80.
1.35 divided by 35 = 1%
35 divided by 100 = .35
0.35 times 80 = 28/80

2. 100 divided by 100 = 1%
80 divided by100 = 0.8

3.80 divided by 100 = 0.8
So each square is 0.8

4.Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review

5.The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.
There are more people in Ms. Stanzi's class than Ms. Lowrey's class. So I think she is correct.

Question 1:What is a good definition of percent? You should use words, symbols, pictures and numerical examples in your definition.
A percent is a fraction of 100. The symbol % means 100 in french.
example:55/100 = 55%

Question 2:How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show your answer.
They are all the same because if you make them all a percent it will be all the same. For example 3:2 and 3/5 are the same because when you convert 3:2 it will be 3/5. 3/3+2=5 then that is 3:2. 60% is the same as o.6 because 0.6 converted into a % is 60 and 60% converted to a decimal is 0.6.

Question 3
Show 3 different ways to find 35% of 80.
1. 35/35= 1%
35/100=0.35
0.35/80=28 /100

2. 100/100=1% 80 divided by 100 = 0.8

3. 80/100=0.8

Question 4:Find a link to blogs that deal with percentages. Leave a comment behind and add the link with review.http://linden8m.blogspot.com/2006/11/understanding-percentages.html#links

Question 5:The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not
I she correct because there is more children in Ms. Lowery's class.
20/40 = 50%
11/20 = 55%

Question 6
Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.
a) 16 is 40% of what number?
b) what is 120% of 30?

40/40=1%
40/100=0.4
0.4x100=40
40/100 = 16/40

120/120=1%
120/100=1.2
100=30
1.2x30=36
120/100 = 36/30
