### Scribe Post for January 30, 2009

Today in math, our class started off with Number of the Day which was 2 969.402

1. 6 - 3x = -6
2. 5x / 4 + 3 = -7

3. x / 5 = -3 / 4

These are pretty hard questions to answer so Mr. Isfeld told us steps to answer them.

Step # 1

Take away not needed numbers by doing their opposite operation so you can cancel them out and what you do to one side of the equal sign you do to the other.

Step #2

Step #3

Find what the letter is.

After finding everything, verify by writing down the equation and then replacing the letters by the answer.

Here are some of the practice questions Mr. Isfeld gave us:

1. b - 2 = 4

b -2 + 2 = 4 + 2
b = 6

Verify

b -2 = 4
6 - 2 = 4
4 = 4

2. a + 3 + a = 5

a + 3 - 3 + a = 5 - 3
a + a - 2
2a / 2 = 2 / 2
a = 2

Verify

a + 3 + a = 5
1 + 3 + 1 = 5
4 + 1 = 5
5 = 5

3. 3d = 9

3d / 3 = 9 / 3

d = 3

Verify

3d = 9
3(3) = 9
9 = 9

4. 4 / f = 4

4f / 4 = 4 / 4
f = 1

Verify

4 / f = 4
4 / 1 = 4
4 = 4

After doing the algebra, our provincial folders got handed back to us and we finished doing our worksheet about ordering fractions and decimals in ascending (least to greatest) and descending (greatest to least) order. We also had to put down a goal about ordering the fractions.

Today in class we started with number of the day which the number was: 1245.839(Onethousand twohundred fourty-five and eighthundred
thirty-nine thousanths) and went into a test on the 'Balancing Act'

I made a sample picture for people who would like to see how it was . We also did a easy algebra question .

Today's class we worked on number of the day, 1269.584

Then Ordering Fractions Strategies.

1. Using landmarks, landmarks are things everybody should know.

eg. Let's meet at polo park.

I live near the forks.

bold words are landmarks

Fraction landmarks include:
1/10, 1/5, 1/4, 1/3, 1/2, 2/3, 3/4, 1/1

Practice: which is larger 11/15 or 7/10

Using our second strategy finding common denominators we see that 11/15 equals 22/30 and 7/10 equals 21/30. There for 11/15 is greater.

Third startegy is converting to decimals. Decimals are always over or out of one. So we follow the same steps as equivalent fractions only this time our equivalent fraction must be over 1.

For example: 3/5 converts to 0.6/1. We must divide 5 by 5 to have a denominator of 1. Therefor we must also divide the numerator by 5. So we get 3 divided by 5 equals 0.6

Things to remember a fraction is a part of a whole.

The line seperating the numerator and denominator means divided by.

In today's class we did Number of the Day . Today's number was 3269.148 .

After Number of the Day , we did a balancing act .
The total for today's balancing act is 48 .
Here is a picture for the people who didn't
have enough time to draw it down .

We also worked on our provincial folders .

We had to order fractions from ascending and descending .

ascending - to order numbers least to greatest .
descending - to order numbers greatest to least .

### Scribe Post For Jan 23

Today in class we had to go over yesterdays homework.

The homework was the balancing act.

It looked like this:

The total for the whole balancing act is 160.
Here is the answer for the people who
didn't get a chance to write it down
during class.

Also, today we started our provincial folders.

For the first segment of proof that we had to put in our folders

eg. Put the following decimals in order from least to greatest.
1.3 0.9 0.2 0.8 1.2 1.6 1.8 0.1

In order the numbers would be:

0.1 0.2 0.8 0.9 1.2 1.3 1.6 1.8
If you got something like this right on the sheet you would have to give yourself one check mark and put the date next to it. if you didn't get to put any check marks on your sheet, you would have to come another day and try to get it right a second time.

Today at Math class, my class had a test ! The test had 42 questions and it was about percent, decimals, fractions, outliers, range, mean, and mode. After the test, we had to do Number of the Day. If we finished Number of the day and still had some time, we had to do a balance question. It looked like this :

Sorry if I made some mistakes in the picture. Those looked like the shapes that I copied down.

After that, we corrected our tests. That was pretty much what happened in Math today.

Here is a Math video. It is called Mathmaticious ( Math-ma-tish-iss ). This video is about math and it has the tune of Fergie's song called Feralicious. I put this video on the blog because it's funny and it mentions some math that we have been doing. The video actually starts at 30 seconds. I hope you like it.

Thank you for visiting my scribe post! I hope you liked it !

Today we did math link page 437-439 1-16We have a Quiz tommorow jan 22 2009 its about

Decimals-A linear array of digits that represents a real number, every decimal place indicating a multiple of a negative power of 10. For example, the decimal 0.1 = 1/10 , 0.12 = 12/100 , 0.003 = 3/1000 . Also called decimal fraction.

Fraction- a number expressed as a quotient, in which a numerator is divided by a denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator. If the numerator is greater, it is called an improper fraction and can also be written as a mixed number — a whole-number quotient with a proper-fraction remainder. Any fraction can be written in decimal form by carrying out the division of the numerator by the denominator. The result may end at some point, or one or more digits may repeat without end.

Percent-, a quantity can be increased by any percentage but cannot be decreased by more than 100 percent. Once pollution has been reduced by 100 percent, for example, it ceases to exist. In defiance of this logic, however, advertisers sometimes refer to a 150 percent decrease in lost luggage or a new dental rinse that reduces plaque on teeth by over 300 percent. Presumably what is implied by the latter is that the new rinse is three times as effective as some other rinse, but such constructions are still subject to criticism as illogical.·Percent can take a singular or plural verb, depending on how the quantity being described is viewed. Very often what determines the form of the verb is the noun nearest to it. Thus one might say Eighty percent of the legislators are going to vote against the bill or Eighty percent of the legislature is set to vote the bill down. In the second sentence the group of legislators is considered as a body, not as individuals. When percent is used without a following prepositional phrase, either a singular or plural verb is acceptable.
Measures Of Central Tendancy
mean- The MEAN is the arithmetic average, the average you are probably used to finding for a set of numbers - add up the numbers and divide by how many there are:Eg(80 + 90 + 90 + 100 + 85 + 90) / 6 = 89 1/6.

mode-The mode of a set of numbers is the one that occurs most often. So, in the set {1,5,7,5,9}, the mode is 5 because there are 2 fives and only one of each of the others.Now here is a problem for you: Find the mode of this set of numbers:2 6 9 0 5 2 4 1 6 4 5 2

median- Median is the middle value of the given numbers or distribution in their ascending order.Median is the average value of the two middle elements when the size of the distribution is even.

Range-Example 1:The Jaeger family drove through 6 midwestern states on their summer vacation. Gasoline prices varied from state to state. What is the range of gasoline prices?\$1.79, \$1.61, \$1.96, \$2.09, \$1.84, \$1.75Solution:Ordering the data from least to greatest, we get:\$1.61, \$1.75, \$1.79, \$1.84, \$1.96, \$2.09highest - lowest = \$2.09 - \$1.61 = \$0.48Answer:The range of gasoline prices is \$0.48.

Outliers- For a set of numerical data, any value that is markedly smaller or larger than other values. For example, in the data set {3, 5, 4, 4, 6, 2, 25, 5, 6, 2} the value of 25 is an outlier.I

In class today we learnt from our abusive math teacher (Do'nt hurt me) He decided to let someone not so abusive teach us named Mr.Piliske .Mr.Piliske taugh us today to play a game in this game everyone has a card . On that card there was either a equivalent fraction , Percent, Improper Fraction, or a Picture Representation.

Eg.

I have two and a half 2 1/2. Who has an picture representation of one third ?
I have one third who has Equivalent fraction of 0.25? I have 1/4 .Ext....

After that our abusive teacher assigned us to do some textbook work on page 437 starting at number one going on to whatever number we could possibley get to before the class was over.

Here are all of the questions on page 437 :

1)In you words explain what a range and a outlier is?

2)How can you determine the smallest value in a data set if you are given the range and the largest value? Use an Example to explain your response.

3)What is the range forthe data set of:
a.11,8,7,10,6,5,18,13
b.4,-5,3,-2,0,7

4)Determine the range of each set of data:
a.16,11,7,29,31,18,21,18
b.7,1,-1,-2,9,-7,4

5) Leanne timed how long she could hold her breathe under water.She recorded the following timings,in seconds:47,55,42,65,61
What is the Range of the data set above

6)What value(s)appear to be outliers in each data set:
a.6,9,9,37,8,7
b.24,34,46,26,32,43,115
c.48,32,67,61,47,95,89,888,1

7)Identify any possible outliers in each set of data
a.666,11,9,12,8,13,10
b.43,54,62,64,0,211,45
c.82,,75,7685,89,95,92,88,80

In class the other day we learnt from our super "cool" math teacher . We started class by doing our number of the day, then isfeld put this on the overhead

Total is 80. 1 shape weighs more than
9

It was kind of tough to figure out, but after about 10-20 minutes, we figured it out all together. and this is what we came to.

### Congrats to All of You! :D

Great job you guys!

It has only been 2 days since you were taught how to use Blogger (better), and you guys are using those notes pretty fast. It's also nice to see that a lot of people are leaving comments behind. Keep it up! If you do, we'll hopefully see more visitors checking out our blog (by looking at the Cluster Map). I'm sure that Mr. Isfeld and Mr. Harbeck are also very proud of you all.

Keep up all the great work!

### Scribepost for January 14 2009

Today in Mr Isfeld's class we talked about how to add a link,images,videos and how to change a font.

First, in the title you put Scribepost for and you put the date today
Eg. Scribepost for January 14,2009

And in the Labels you put your name and your room number and put Scribepost

Eg.Celdrick772, Scribepost

Upload an image- first you must click on the square picture that says add image. Then you click Browse and you look for the image that you like. You can also pick where to move it and you can also change the size.

Adding a link- First you highlight the word that you like to be linked, then you must copy the website that you chose, then you paste it on the URL and you click OK. Then the word will change colour and that's when you'll know when the word has been linked. Then you can click it and then the website will pop up in a new window or a new tab.
Eg. Median is the middle number.

Adding a video- First you can pick a wesite where they have a video. For example Youtube or Photobucket. You look for the video that you like.Then you copy the Embed and some of them might not have any Embed. Then you click on the Edit Html and you go all the way down and paste it. Then click Preview and you will see the video that you added.

Changing the font- First highlight the word that you want then click on the arrow where it says some fonts. For example Georgia. Then click outside the box and you will see that the font changed.

Changing the colour- First highlight the word(s) that you want to change. Then go at the Letter "T" with the colours. Then you click the colour that you want and click outside the box. Then the colur will change.

I pick Karra next.

Today in Mr. Isfeld's class we did our number of the day test. He looked at Celdrick's Post and we looked at the map and talked about how we want more people looking at our blog. We reviewed our homework from yesterday which was...
A. 23, 17, 24, 16, 23, 23, 7, 27, 22, 28

B. 7, 14, 8, 11, 8, 12

In the previous days Mr. Isfeld has taught us about the Measures Of Central Tendencies. There are Median Mode and Mean.

Mean-is the sum of a set of values divided by the number of values i the set.

Eg. 1,2,3,4,5 first add all the numbers and it all equals 15 then count how many numbers there are and then you divide it. 15÷5=3 that is the mean.

Mode- is the most frequently occuring number in a set of data.

Eg. The mode in 3,5,7,7 and 9 is 7.Modes of 2,2,4,6,6,8 and 11 are 2 and 6.The data 1,3,4, and 5 has no mode.

Median- is the middle number in a set of data after the data has been arranged in order.Eg. The median of 2,5,6,8 and 9 is 6.If there are two numbers in the middle you just add it and you divide it by 2.

Eg. The median of 1,3,6,8,9 and 10 is 7.6+8+1414÷2=7therfor the median is 7.
