My reflection about the proportion and ratio table unit:

My favourite part in the unit was doing the things in the blue book. Like doing the fractions, and finding the percents by doing ratio tables and x k y charts. I thought it was really easy. But sometimes when i do ratio tables, I get confused with what numbers I put for the Part and Total.

What i find that's difficult in the unit is making shapes larger or smaller without changing the shape. I don't understand the steps in doing that. So i should ask someone who knows how to do it before the test, or else I won't do good on my it.

I learned alot of new things this unit. Learning how to do these questions many different ways sometimes gets me confused. But doing these charts helps make work easier.

In this unit I learned alot! My favorite part of this unit was using the ratio tables and equivalent fractions. By using those it made it much more easier and clearer to understand.

The hardest part of the unit for me was the xky charts cause I didn't really understand them but today Mr. Harbeck explained it to me and now I understand.

February 05 / 2007 MORNING scribe

okay .. today we started off with a test

There was only ONE question .. but two parts :
A. Use the Graph Paper below to reduce this diagram to half its original size.

heres what I did :
First i found the area of the biggest rectangle by length times width. so that 6 X 8 = 48 .
Second I found the area of the triangle on the top . Finding the area of a triangle needs one more step . So the triangle's width is 4 and length is 8 .. so 4 X 8 = 32 BUT a triangle is HALF a square/rectangle .. so you have to do 32 divided by 2 =16
Third I did the chimney all i did was count , because part of the chimney was covered by the triangle and the area of that is equal to 6.
Fourth I added all the numbers together. 48 + 16 + 6 = 70 so the area of the house is 70
Fifth I divided 70 by 2 and i got 45 . Then I divided each section by 2 (e.g 48/2 , 16/2 and 6/2) then i drew it on the other side of the graph paper




B. What would the area of the door be if you enlarged the diagram to twice its original size? Show how you solved this question.
First i got the area of the door .. which is 8
Second I multiplyed the door's area (8) by 2 to DOUBLE the size
Third .. to make sure I got the question right .. i just made sure that TWO doors could fit in that one door.



P.S. DONT COPY WHAT I JUST DID .. its just what I did .. not EVERYTHING i do it right .. in class today Mr. Harbeck said something about people that do good in the class would not do good in this test or something xp i forgot









then for the rest of the class we talk about "BlogginOnBlogging" where we had to type a reflection on the math unit for 4 EASY marks . Then we worked on our booklet thingys for the rest of the class.

I WOULD do the aftn class but thats "UnKnowN J." 's job

hmm .. maybe he should pick tomorrow's scribe , becuase i dont know who to pick xp

This is my reflection on the past math classes and the white book:

During the past few classes we have been learning about different ways to solve questions like: the x k y chart, the t-chart, the part over total chart, and the cross multiply chart. I think these charts help a lot because they make work easier to see/understand and it helps your work look neater.

I think my work on the questions we got today in class really helped me understand more because we had to use at least two different ways to find the answers. It helped me understand more on how to use the different charts, and the amount we had to do really helped to understand questions and how to use the charts.

The thing I found hard about the white book is figuring out the length and width of things. Like question #1. What I also found hard was solving the missing measurement and putting it into the charts. Also, at the beginning of the subject I didn't understand how to figure out were to put the numbers in the x k y chart and how to work the t-chart but I'm slowly understanding how to work the different charts.

The thing I will try and do next time is if i don't understand something in class I will ask Melissa or Thyrza to help me understand, even though they help me in class I will go to them earlier in time so I understand everything in class.

Scribe Post for this afternoon

Today in math class Harbeck gave us a quiz in the morning. In the afternoon Harbeck told us about the test that he's going to give us. The test is out of 36 but there is going to be 4 bonus quetions. So it makes the test out of 40. Harbeck also told us about a BOB. BOB stands for Blogging On Blogging, which doesn't makes sense. Anyways, in this post you will write a reflection on this whole unit that we have been doing for a month now. You must lable this post BOB or else Harbeck will get mad. In this post you must write/type a reflection on how you think you did in this unit. An example would be: I think I did well on ____________ since we started the blue book because____________. I think i could of done better on ___________.

Oh i also remeber than in class Harbeck was yelling at Sarika for making him repeat was he said over again cuz she has "bad hearing".

Here are the answers the the first 5 questions:

1. lbs/$ = 6/9 = 21/31.5

2.ft2/$ = 5000/24 = 30 000/114

3. ft/$ = 20/180 = 300/2700

4. inches/feet = 1/5 = 8.5/42.5

5. sales tax/purchase = 4/50 = 96/1200

Unfortunately i coudn't get the rest of the question done. Sorry for making the pictures hard to see! Oh and the next scribe is Ardia! bwahahahahahahah!

Thyrza's BOB !!!

This is my reflection about the proportion and ratio table unit .

This unit was interesting and also very challenging. My favorite part was answering questions by using x k y chart, ratio tables and equivalent fractions. By using those things it made my answers really clear. If you use one of those things you could also use the other two to check if your answer was correct.

The hardest part on this unit for me is increasing something or even decreasing it. Until now, I’m still confused because I’m not sure if I’m supposed to double the dimension or the original area. I’ll try my best to learn how to do it correctly before our big test on Wednesday. This unit, I sure learned something! I learned that I shouldn’t make a simple question complicated because I would get the question wrong. I hope we all do well on the test on Wednesday to make all our marks higher.

If anyone has any questions or is having some trouble with something like ME, I suggest you ask someone in your class or Mr. Harbeck before the test come so you’ll do well on it.

MAKING MISTAKES IS NOT WRONG BUT CONTINUING TO MAKE MISTAKES IS! SO DON'T BE AFRAID TO ASK!

Scribe Post!!

Yay! It's my turn to make another scribe post! ^^ Okie Dokie....Today in math.... *opens eyes* I woke up and saw on the board... *eyes widen* A math starter! Mr. Harbeck asked us, "Okay, children.. Find a way to beautifully answer this question."

Okay, okay...I know I'm over reacting...But I can't help it! Everytime I do a starter I get hyper. *ahem* I'll continue..

This was what was on the board:

What is the best deal?
20ft area rug $105
10ft area rug $60
40ft area rug $220

This was how the class solved the problem:

Okay. Another thing that I remember doing in math today is that booklet. Yes. The one questions...the project...Yesh that's the one! hehe. I remember Mr. Harbeck saying something about question 8. He said to call the figures A and B.



















The answer is 12.

Right next to that diagram, put down:












The answer is 16.5.

*spins in circles* Sorry if I'm missing things... My mind is so overwhelmed right now. I owe so many things to ppl...(drawings mostly) and my computer is giving me a hard time. *starts panicking* I'm sorry Mr. Harbeck if I don't get all my homework done. My to do list is flooded. My siblings are also bugging me. Homework reasons, and I just can't take much more! Hopefully I'll get everything done by tomorrow...But, from the way things are right now, I could tell that I'm gonna have to be an insomniac tonight...-_-"
