Okay so today there is two different scribes. I will be doing the fraction word problems. The first one is the easiest one to do.

So the first part is that the theme of these question are that Betty is planning a birthday party for her little brother.

Here is the question and the work:

Just click it to make it bigger if you find it hard to see. Anyways as I put on the page that if you ruined 3/8 of something you need to use the 1/2 for the ice cream in the tub to fix it, right? So then you would have to add what is left of the cake to what you have of the ice cream that could be used to remake it.


I don't get problem number two. The whole hot dog thing. I couldn't turn it into a equation. Which I think is really dumb but what can I do. So to anyone that does know what to do I hope that you make a comment on this Scribe Post and tell us your theory. We would love to hear it.

Anyways onto the last question. I was a bit confused on this one to but I think I get it and if I don't again the whole comment thing. People like to correct their mistake or at least know what they are, thank you very much.

So as you can see I like to do things the hard way but I did simplified it in the end. This one was kind of hard because of the 3 fractions but I did it the way one of my friends suggested. It looks right to me. Anyways that is all I had to do. I hoped it helped you.

Okay so Mr. Harbeck asked us to make a post relating the words and the pictures to all make sense in the end. Here is my post.

I'm going to start with the Right Triangle.

So as you can see it the picture above it labels are 3 out of 5 vocabulary words that were need to use and one picture. I'll explain them a bit better.

Hypotenuse- The Hypotenuse is the longest side in every right triangle. It is always located across from the right angle and would be label 'c' in the equation(later in the post).

Legs- They make up the 90° angle and are always labeled 'a' and 'b'(Later).

R.A.T- R.A.T means Right Angle Triangle.

Next that last two words explained and two more pictures.


Okay so the word Greek is related to the whole thing because that statue is of a Greek mathematician, Pythagoras. Pythagoras has a theorem 'a² + b² = c²' named Pythagoras' Theorem.



This man proved that he could turn four right angles into a square and vise versa.

So this is the idea.
This is the Theorem. Now the idea is to make it into a whole bunch of triangles like so:
Here are a couple of videos that Jordan and I made in class.
The first movie explains how a² + b² = c² and the second on explains how to find out what b² is.


Movie One:



Movie Two:

I don't have any pictures to share because my camera is broken.

This year for the first time since I have moved to Winnipeg I was home for the winter break and not in Ottawa. I planned on shoveling a few of my neighbours walkways each time it snowed heavily. I would start as soon as possible.

What happened was that my next door neighbour was going away to Alberta for the holiday and she asked my mother if she could watch over the her house. Like collect her mail and shoveling her walkway. I volunteered to do it for her. It was nice to be able to do something for like this for my neighbour. She is in her late 80's or early 90's so I didn't ask her to 'Pay it Forward' like I should have because she is very old and I wouldn't be surprised if she has done favours for others with out anything in return.

One person can make a difference. Atleast that is what I think. If you work hard enough it can happen one wat or another and it all has to start with one person for it to get anywhere at all.

Rule for Multiplying: (Free Verse)
If you Multiply a Odd amount of Integers,
makes a negative product.
Multiply a even amount of Integers it will make a....
Positive Integer?!
'Is this true!'
'Does it work?'
Yes it does,
So do not doubt it,
Do not mock it,
But you may use it,
Unless of course you want to fail.


Subtracting Integers: (Picture Poem)

Well I have been away for a while so here I am stuck in the room 17 until I finish my work and this happens to be one of the things I have to do. So I shall be doing this post on the subtraction of integers because....

Lights were flashing every where, people were scattered around having fun, eating and laughing. It was noisy, very noisy but what could you expect when at a Carnival. People were always laughing and screaming on rides or with friends.

Anastasia, our main character here was celebrating her birthday with her friends, which names are Emily and Danielle. They were having so much fun. They had just ridden the biggest and fastest roller coaster an even eight times. Now they were hungry and wanted to try there luck at the games.

They headed over to the nearest food stand. They where going to get some pizza and drinks. "Hello. What can I get you?" Said the kind man in the trailer, at the cash.

Anastasia, being the person she was always planned out her what she order so she knew what she was paying and what she would get back. Looking at the board she decide she would get a medium pizza and three drinks which would be seven dollars. "I would like a medium cheese pizza and three canned drinks please." She replied only about a minute after.

"Sure. That will be seven dollars." He said with a smile, then turned around and started to make the pizza. She pulled out a ten dollar bill.





When the man turned back with Anastasia's order she handed him the ten dollar bill and received the food and the change back. They all head for the nearest clear table and sat down. Anastasia put the pizza box on the table then took the drinks off the box and in front of each girl and herself. They ate and chatted about nothing special for a while.
