### Scribe Post for November 25, 2008

Today's homework is page 7 numbers 19 and 23 , and page 8 numbers 1 to 18 .

page 7 ,

page 8 ,

This is some of the homework , and if i did anything wrong feel free to leave a comment . And tommorow we will also have a quiz on what we've been doing so far. I guess this is the time for me to pick the next scribe , the next scribe is KATRINA (:

Then we had to decide if either it was a partitive division, Quotitive division or neither. Mr.Harbeck told us that if you picked Quotitive you would go to the left side of the room , If you picked partitive you would have to go to the rigth side of the room, then for the people that picked neither was at the back and for the people that didn't know went to the front of the room . Well most of the people were at the back of the room because it was neither . And in the end of the discussion all of us where convinced to go to the back of the room because you cant share a negative numbers and you cant share a negative group. And all you can do is the multiplicative inverse.

The home work for today was page 7 , from 10-17 . The next scribe is GIAN !!

*"barn doors"*(barn doors are the one we have been working on for the past month. but this time we are using the white barn doors). -12/ 4 fits in the 2ND quadrant (negative and positive). Then, he asked us how to write -12/4 in a different way. You could write it by what he calls

*"gasinta"*(means goes in to).

*"Quotitive"*(its when you make a number into equal s,and how many groups there are) for example: 6/2

And

*"Partitive"*(its when you share the number into equal groups, and how many are inside each group) for example: 6/2

*"Quotitive and Partitive"*

Quotitive; how many groups of 4 are in 12?

Can you do Quotitive in this type of numbers? answer is no. because you cant divide a positive if there are no positives. But someone asked, why cant you use zero pairs? Because you cant put zero pairs if you have something in there, and in -12 you have something.

*"Quotitive".*because in

*"Partitive"*you cant share a negative with anything. Then, we have to put the integer numbers in a

*"multiplication inverse"*-6 / - 2 = 3 : 3 x -2 = -6

*"booger book",*we have to do page 7, 1-9 but only answer the 6 question that fits for the 3 quadrants we already went through. And then draw only 3 of any questions. (the 6 questions that i thought fits are 1,3,4,5,7,8) I'm only going to show the 3 with drawings. (its 3,4,5). And we have to put if you could use Quotitive, Partitive or Both.

3. -6/ 2:

*"Partitive"*share -6 into 2 groups, how many are in each group?

*"Quotitive"*How many groups or -1 are in -5?

*"Partitive"*Share -14 into 2 equal groups, how many are in each group?

Hello everone! I'm today's Scribe again. Today I'll be talking about what we did in class and homework. It's so nice to be the Scribe again.

First off, we worked on our

**"barn doors",**we did quadrant 2. We learnt how to express a division integer question. There are a lot of ways to do that.

**EXAMPLE:**

-6/2

Fraction way:

Division way:

Quotative: How many twos are in negative six

Partitive: Two groups of negative three.

For homework we're supposed to do quadrant three. In quadrant three and quadrant four. In quadrant three and four we were supposed to the same thing as I have shown you in the picture. We're supposed to express it in the division way and the fraction way; then we were supposed to write it in words which is quotative and partitive.

That's all we did for today. Do the homework. Please also don't forget to put a comment after reading this. Tomorrow is iPod day and Mp3 day don't forget to bring a dollar! >;P next scribe is.. (drum roll) Chinn! I mean Christian ;). Good luck Chin! Well I'm almost done. One more reminder if you need help in math, math room's always open during lunch if you need any help. Well I sure had a lot of FUN doing the Scribe can't wait 'till the next. BYE! I left a video and a link to help you.

On Friday we did several things. The first thing we did was correct our homework from the day before. The next thing we did was add to Pratt's Integer Law to help us with our home work. So far this is what Pratt's Integer Law is:

When multiplying an even amount of negative integers, the product will always be a positive. On the other, when multiplying with an odd amount of negative numbers, the product will always be a negative. Also, when multiplying a zero, the answer is neither a positive or negative but just a zero.

After discussing this, we learned about what this really means:

Mr. Harbeck then gave us homework, which was 19 to 36 (basically finish the section). I'm now going to show you how I answered 3 of the questions for homework.

Question #18

(-8) (-1) (-2) (-1) =

Before we left he gave us 3 questions that we should try and figure out how to answer. To help me with this, I used B.E.D.M.A.S. (Brackets, Exponents, Division, Multiplication, Addition, Subtraction). This is the ORDER OF OPERATION!

This is how I think they are answered.

Question #1

2 (-3) + 2 (-3) =

So for the next scribe, let's ask the lawmaker, Pratt, to tell us what is going on. Alright? Good!

This is what the paper looked like:The rule is called the Pratt's Integer Law (:

- When you multply an EVEN amount of negative integers the product is always positive.

**IT LOOKS**

**LIKE THIS:**

For the questions on page 5, i chose number 5, 7, 8, and 11.

**5) (6)(-2)=-12**

**7) (-5)(-4)=+20**

**8) (6)(9)=+54**

**11) -12(3)=** -36

That's all we did in class today, i hope u learned something. I'm sorry if there's any mistakes.

**THE NEXT SCRIBE IS!!!!**

**MELISSA!!!hahaha...GOOD LUCK ON THE NEXT SCRIBE MELISSA....**

### scribepost for november 6, 2008

Yesterday (Nov. 5th) we talked about each quadrant having 2 operations such as quadrant 1 with + and +. These are integers. Mr. Backe gave us questions yesterday and we all solved them in quadrant 1 and 2. For example, in quadrant 2, the question was (-2)(+3). We didn't see any signs of operations, but we remembered that last year we found out that if 2 brackets touched then we multiplied, but how do we do this? Well, -2 is just like saying "remove 2" and if we're multiplying we say "remove 2 GROUPS of". Now that just leaves the +3. "Remove 2 groups of +3) Well how can we remove anything if we don't have anything? Mr. Backe helped us with this and told us that we can take as many zeros as we can (zero pairs) and THEN take away whatever you need to take away.

We had homework on this and we were supposed to make up our own questions just like this one and solve it for quadrant 1 and 2. People shared their questions and we all solved them. Then we noticed that when you multiply a positive and a positive, then your product is also positive. We figured this rule would also go with the rest of the quadrants but with different products so we tried it out. We came up with a sentence for each quadrant.

We had a very long discussion about this and somehow it kept going 'till the end of class...which I was very happy about...no work....:)

Time for me to pick a scribe and get back to my Xbox360! ..hmmm.....

...*ahem*....yea, Bobby it's your turn >.> ...........

.....*ehem* PURPLE *cough*.... <<<<<< pretend that's purple 'cause I can't change my font color. The font color menu thingy won't open up -___-" oh well....
