Hello again everyone! I'm the scribe for November 5, 2008 (as the title also states). In today's class we had a guest teacher in the room, Mr. Backe. While he was asking us what we were learning in class and what we knew about the topic, (as if he didn't already know) Mr. Harbeck was handing out giant blue and white papers. Mr. Backe then instructed us on how to actually fold the papers into the shape you'll see below. He also told us to write positive and negative signs on it just like a coordinate grid.

He then told us what the paper was for. It's going to be used to write things we learn about multiplying integers and later dividing them on the white side...the back which you can't see. After all this we started to write things on the actual piece of paper.

You probably can't see those things up there so I'll tell you what the open flaps say. The two middle ones were homework but we'll get to that later.

On the right flap (the positive, positive flap) we wrote the question (+2)(+3)= and underneath wrote When the brackets touch they multiply (in Mr. Harbeck's words they kiss and then multiply). After that we solved the question by figuring out what the question is saying. It was saying 2 groups of (+3). Then we wrote that next to the question in algebra tiles. Afterwards we put the answer to the question after the equals sign (as we always do). There's a picture of it all below if you're too lazy to read this....

Then we had to write something on the left flap (the negative, positive flap). We wrote the question (-2)(+3)= and underneath wrote This question says... Then underneath that we put the words Remove two groups of (+3) because when you have a negative first it means remove. Next, under remove we put (-) and under two we put 2. After that we put algebra tiles under it. There's a picture for it all...don't worry.

That's all we did in class today...yes, it was a relatively easy class...except for...

Homework

Don't cry! It's easy. All you need to do is make up a question like the ones on the flaps but this time you write them on the insides (what's under the flaps when your paper is closed).

That's all for today so...goodbye! Oh! Except for who's the next scribe. The next scribe is Carlo (he asked so...his wish is my command I guess)!

Today in calss we worked on bedmass and integers. The bedmas was used in the integers .

(8-17)-(4+6)=
(-9)-(10)=
-9-10=-19

This would be an example of a bedmas question. One of the integer questions we did together in clas is.

-(-2)-(-6)-15 = -7



The homework that Mr.H asigned was part 2 the odd questions and part 3 in the green booklet .
Here are 3 questions from part 2.

1. 8 - (-7) +3 - (-5) = ?
3. 8 - (-4) + 7 -(-2) = ?
5. 12 - (-3) + 6 - 9 = ?

Here are 3 Questions from part 3.

1. (-9-3) - (-15) =?
5.(-5-3) - (-1-3)=?
4. (8-17) - (4+6) =?

Here is a video of integers.
And I choose Karen for next scribe :)

In class we learned about how to subtract integers
But execpt you dont subtract you ADD THE OPPOSITE.
for example:(-8)-(+2)
(-8)+(-2)=+10


You never subtract.here are the answers to pg46

k, Well today in Harbeck's class we have been learning about integers, just today was different because he gave us a booklet that didn't have brackets around each integer "Inetegers in standard form" That meant we had to learn all this new stuff, I personally thought it was standard enough but anyway



-4 -3=-7 6+8=14

owe 4 owe 3= -7 have 6 have 8= 14



When Do You Add The Opposite ?


8-(-7)+3-(-5)=+23


8+7+3+5=23


pretty much whenever you have to negatives or "uhhh ooos" i think ?



you guy if anyone even lokks at

this can get the answers from john

or carlos i think any way i

feel like poo soo good night

p.s. i couldnt get pictures so i

did the best i could with the

font sizes an that stuff

Today at October 30 2008 in class at period 3 we just got a green booklet but it wasn't an ordinary booklet, it was a booklet of integers. And in that integer booklet, there were problems, subtraction and addition. But they were not any ordinary problems, they were simple and straight forward problems but with no training wheels or brackets if you prefer. Now here is a hint for all y'all people, if you see a bracket in a problem with two integers it's just tricking you. but if you see a bracket in a three or more integers in a question y'all just have to do the simple rules of the addition or subtraction problem. If y'all just look at the bottom of this paragraph.










Dudes here's another.
