SINCE ADDING SIDE A AND SIDE B GIVES YOU SIDE C, TAKE AWAY SIDE A FROM SIDE C TO GET SIDE B

OR

C² - A² = B²

WITH THAT YOU CAN THIS:

C² - A² = B²...FORMULA
10² - 6² = B²...REPLACE A & C
(10X10) - (6X6) = B²...SQUARE A & C
100 - 36 = B²
64 = B²...SUBTRACT

YOU ARE NOT DONE YET. YOU FIVE B², YOU ARE LOOKING FOR B. YOU STILL HAVE TO FIND THE SQUARE ROOT OF YOUR ANSWER TO FIND B.

THE SQUARE ROOT OF 64 IS 8 (8X8=64).

B = 8

Finding C

One of the most famous mathematicians who has ever lived, Pythagoras, a Greek scholar who lived way back in the 6th century B.C. (back when Bob Dole was learning geometry), came up with one of the most famous theorems ever, the Pythagorean Theorem. It says - in a right triangle, the square of the measure of the hypotenuse equals the sum of the squares of the measures of the two legs. This theorem is normally represented by the following equation: a2 + b2 = c2, where c represents the hypotenuse.

With this theorem, if you are given the measures of two sides of a triangle, you can easily find the measure of the other side.




Example

1. Problem: Find the value of c.

Accompanying Figure

Solution: a2 + b2 = c2 Write the Pythagorean
Theorem and then plug in any
given information.

52 + 122 = c2 The information that was
given in the figure was
plugged in.


169 = c2 Solve for c By finding the square root of the number
c = 13







2. Problem: A ladder 12 meters long leans
against a building. It rests on
the wall at a point 10 meters
above the ground. Find the angle
the ladder makes with the ground.

Solution: Make sure you know what is being
asked. Then use the given
information to draw and label a
figure.




a2+b2=c
12,2+10,2=c
c2=144+100
c=244
square root of 244 is 15.62
c=15.62

This unit was pretty easy. In the beginning of the unit I was lost, but now I understand fractions, completely. I need to do better in the quizzes. I work during class and usually complete my homework on time. I worked hard on the unproject with my partner but it was a few days late.

Required Information:
1. Did you like the unproject.
It was okay.
2. Did the unproject make you work harder than you usually would?
No because this was on done on the computer and it's much easier.

Creating questions for the quiz.
4. What would you change about the next unproject?
Nothing.
5. Did the unproject make you learn more because you were doing a different type of project?
Yes, I learned how to use tools on the internet such as creating slideshows and using wikispace.

B.O.B

I think i did really good on this unit about fractions. I found it easy to learn how to add, subtract, multiply and divide correctly. I completed all my purple sheets, big sheet and my unproject. I think i will get a good mark when take the test.

Did you like the unproject?
I liked the unproject because it prepares me and others for the test.

Did the unproject make you work harder than usually do?
I tried the best i could like on most of my projects.

What did you like about the unproject?
The best part was when i was done because i was happy =)

What would you change about the unproject?
nothing i guess

Did the unproject make you learn more because you were doing a different kind of project?
I learned to add and subtract a bit easier but thats all.

Monday, April 09, 2007

BOB

I think this unit was easy. I learned how to divide and multiply fractions, which i never learned about before. I had a lot of practice by using the purple booklet. I finish my work, and i got good marks on my test.

1.) Did you like the unproject?
Yes, I did like the unproject, I thought it would get me ready for the next teset.

2.) Did the unproject make you work harder than usually would?
Not really, it just took a long time to finish.

3.) What did you like best about the unproject?
The thing i liked the best about the unproject was putting it all together.

4.) What would you change about the next unproject?
I would put a little more work into it and make it look creative.

5.) Did the unproject make you learn more because you were doing a different type of project?
It was more of a review of adding and subtracting fractions.

B.O.B.

Overall the fraction unit was easy. I knew how to do the adding and subtracting. Multiplying fractions wasn't that hard either. Dividing was the hardest but I understand it know. One of my problems that I had in this unit was I would forget to convert mixed fractions into improper fractions when I needed to.


Did you like the unproject?
I didn't really like the unproject but it wasn't bad either. It was alright.

Did the unproject make you work harder than you usually would?
I think the unproject did make me work harder than I usually would.

What did you like best about the unproject?
The best part about the unproject was when it was done.

What would you change about the next unproject?
I guess I would put more effort in the next unproject.

Did the unproject make you learn more because you were doing a different type of project?
I don't think it made me learn more but it was sort of like a review.
APRIL T'S BOB
On this Fraction unit, i had a hard time with dividing fractions and knowing when to divide or multiply in a word problem. I'm still struggling with that. I think the easiest for this unit was adding, subtracting and all those other ones we did. My purple booklet was fun to do. HEHE (:

Did you like the unproject?
Yes, I liked doing the unproject because in a way it was fun, and educational at the same time.

Did the unproject make you work harder than you usually would?
Yes, it did make me work harder than usual because i wanted everything to be perfect so i required a little more work.

What did you like best about the unproject?
I liked making pictures and making the quiz. It was fun because we could put any number we like on the quiz.

What would you change about the next unproject?
I think i would start it when he assigns it to us so it wont be late.

Did the unproject make you learn more because you were doing a different type of project?
Yes, it made me learn more because as i explain about what to do when adding and subtracting, and also multiplying and dividing it made me learn as i was working.

BOB

This fraction unit was sort of easy, multiplying and dividing fraction was probably the part in the unit that was sort of hard. I finished my purple book on time, but in some of the pages the answers don't really seem like their right. I did pretty good on all of my tests and quizzes. Adding, subtracting, finding lcd was pretty easy.


Did you like the unproject.
Yeah I liked doing the unproject because in a way it was fun.

Did the unproject make you work harder than you usually would?
Yes the unproject made me work harder than I usually would work because it took a lot of effort just to make it how I wanted it to be and it's worth ten percent of your mark.

What did you like best about the unproject?
The most thing I liked about doing the unproject was making the pictures.

What would you change about the next unproject?
I would add more pictures and explain the things a bit better.

Did the unproject make you learn more because you were doing a different type of project.
Yes the unproject made me learn more about fractions.

BOB

The fraction unit was easy. I found adding easy. I found dividing hard at first. I didn't do my purple sheet on time which was my weakest in this unit. I liked the unproject. The unproject made me work harder then usually. The best thing about the unproject was doing the questions. If i had a chance to change my unproject i would put more creative stuff. The unproject made me learn because i did different type of project.

BOB >> Blogging On Blogging !

In unit wasn't easy for me at first. But once I got help I got the hang of it. The adding and the subtracting was easy for me to do, but I did ask for help on the dividing and multiplying parts. I did my work on the purple booklet but in some parts I didn't put in how I got the answer. I also put in some of the notes in my big paper.



1.) Did you like the unproject.
- I didn't really enjoy it as much as I thought of, but I did learn stuff on my topic.


2.)Did the unproject make you work harder than you usually would?
- No, this unproject assignment didn't really make me work harder than I usually did for my math and other subject assignments.


3.)What did you like best about the unproject?
- The thing I liked best about this unproject assignment was making pictures. "I like doing things on paint!" :D


4.)What would you change about the next unproject?
- Well I think what Alyssa and I have done is pretty well done. I would also want to put on a quiz on our wikispace as well too. :)


5.)Did the unproject make you learn more because you were doing a different type of project.
- Yes, while doing this unproject assignment I learned more about fractions.


B.O.B

This unit (fractions) was pretty hard for me in the beginning of the unit then i started to do well. I learned alot of things that i didn't learn when i was in grade 1 to 6 like for adding i sometimes forget how to do it then i remember how to do it. I have problems for dividing because i always forget the process of doing it so i have to look it over before tests and the exam. Also multiplication i still have to work hard on that. Adding and Subtracting is okay for me.


BOB
Did you like the unproject.
I enjoyed doing the unproject i learned alot about fractions and how to explain them.
Did the unproject make you work harder than you usually would?
Yes it did i stayed after school and at lunch times to finish it up and Joshua and me completed it and finished before the deadline.
What did you like best about the unproject?
I liked the part where we did the definitions about the fractions and drawing the pictures for the fractions.
What would you change about the next unproject?
I would probably do another unproject like a movie or an animation because that looked very interesting to do and looked fun.
Did the unproject make you learn more because you were doing a different type of project.
Yea it made me learn more about fractions.

Rainer's B.O.B. [@_@]

I think this unit was easy. I learned a lot from the pages in the purple booklet. I learned to divide and multiply fractions. I did all my work and stuff. I did good on the test and some quizzes.

Did you like the unproject.
- I guess it was alright.
Did the unproject make you work harder than you usually would?

- Not really. It just took time to finish.
What did you like best about the unproject?

- Making the pictures for the links.
What would you change about the next unproject?

- The whole project.
Did the unproject make you learn more because you were doing a different type of project.

- It is more like a review for adding and subtracting fractions.

Bob

This unit was really easy for me.In the start i was confused and everything but after we learned more and we had so much homework from the purple book i got to learn it. I find adding and subtracting and multiplying fractions easy too. But i'am not so good in dividing fractions , i know how to do it but sometimes i get mixed up.

Did you like the unproject?
-Yes I kind of enjoyed it because it was really easy for me.

Did the unproject make you work harder than you usually would?
-No because i knew everything about adding and subtracting fractions which made it easy

What did you like best about the unproject?
-The best part for me was making the game because it was fun and easy to make.

What would you change about the next unproject?
-I would not change anything but i would add in a little more information.

Did the unproject make you learn more because you were doing a different type of project.
-No it didn't really make me learn more it just was like a review for me.




These are my notes for my test:

When dividing fractions you have to reverse the second fraction then times them.
If the fraction has a whole number you have to make it into an improper fraction.

When Multiplying fractions you just times them but if it has a whole number make it into a improper fraction.

How to Subtract fractions:If the denominator is the same you just subtract.
If the denominator isn't the same you have to find the lowest common denominator.
If there is a 1 whole number you leave the whole number and subtract the fractions.
If there are 2 whole numbers you subtract both whole numbers along with the fractions

To borrow you take one number away from the whole and add the denominater with the numerator to get the numerator.

Did you like the unproject.

No I didn't because i had so much other stuff to do that i had to do it the last minute and i go it done yesturday April 6. which was do on april 5 thurs.

Did the unproject make you work harder than you usually would?

well not really it just wasted my time just kidding. but i did learn my lesson, I really did. And it did kind of make work hard on it because it kept on bugging me that it wasn't completed.

What did you like best about the unproject?

I thought the best part was making the links and the new pages, because at first i was clueless what to do untill Jullie came to help me.
What would you change about the next unproject?
Did the unproject make you learn more because you were doing a different type of project.

Yes it made me learn more and understand. I'd make a big improvement for the next uproject by planning it and getting started on it.

Bob
This unit on fractions was difficult for me because there was so many steps for the different kind of fractions. For example subtracton frc., adding frc.Sometimes i'd mixed them up. I'd understand what to do but I get nervous whenever the tests and quizzs would come. So i guess I can say i did poorly on that. But this week we are learning dividing fractions and i'm actually working and doing the homewok to get some practise on that.

BOB ( BloggingOnBlogging)

This unit was doing alright with me. It was not to hard and not to easy it was just right. I learned quite a few things that i didn't learn in elementry. Like for subtracting I learned how to borrow numbers from a mix number, although i have problems sometimes on that. I have problems for dividing still because I wasnt there when he taught the class so i have to learn from someone FAST. Also multiplication, i still have to work on that. Adding and Subtracting are easy for me I have no problem with that.



Did you like the unproject?
Yeah, I did like the unproject and especially with abdul! Couldn't do it without him! Haha I also liked how you can learn something and still have fun on that unproject.

Did the unproject make you work harder than you usually would?
Actully yes it did. But i work harder then anything when I work on computer because thats what I mainly do at home anyways so i can just work on something and still chat on msn while working :D.

What did you like best about the unproject?
The thing i like best about the unproject was messing with the HTML , like putting songs and banners. But I could do better but then theres some HTML that dont work with it so I had to leave it out. But the graphicy stuff is just for fun, whats important is that we got the information needed.

What would you change about the next unproject?
I would change the quiz , the quiz was a bit difficult to make because you got one right answer, then you have to make up some other possibilities and its just hard cause its a smile question. So if i had the chance to i'd change the quiz and make like a game or something.

Did the unproject make you learn more because you were doing a different type of project?
No not really because i already knew more about Adding and Subtracting so it didnt really make much of a diffrence.

B.logging O.n B.logging

I found this unit on fractions quite easy, although I'm still having a bit of trouble on subtracting fractions and diving fractions. On subtracting fractions, I don't know how subtract with a fraction that has a whole number and on divding fractions as well.

Finding the LCD or lowest common denominator quite easy. I also find multiplying and adding fractions pretty easy as well.

In this unit I find the tests hard. Although I got good marks in some, I occasionally get lower mark.


  1. Did you like the unproject? Well it was alright. It was sorta hard to make a good wikispace
  2. Did the unproject make you work harder than you usually would? Not really. It was like the wikispace we had to make for our parents, so it wasn't really that hard for me.
  3. What did you like best about the unproject? Putting in the fnishing touches. Like all the color and extra links.
  4. What would you change about the next unproject? I would start a lot ealier so I can get the job done and try different ways to present my unproject.
  5. Did the unproject make you learn more because you were doing a different type of project? I'd make a quiz on the topic instead.

Blogging On Blogging [Fractions & Unproject]

This unit was one bbbiiiigggg review for me. I just forgot division, and that was the hardest to remember. Honestly,this was one of the easiest units of the year for me.


  1. Did you like the unproject? It was , messing with HTML was the most fun.
  2. Did the unproject make you work harder than you usually would? Eh, not reallly.
  3. What did you like best about the unproject? Messing with HTML. ;P
  4. What would you change about the next unproject? I'd start earlier, so I could experiment more.
  5. Did the unproject make you learn more because you were doing a different type of project? Nope, not really.

Bob meng

I messed up on most of the fraction tests. I guess because i didn't understand it that well until now. Now i get adding, subtracting and multiplying fractions. But i'm still geting used to dividing fractions. I hope i do well on the next test.

1. Did you like the unproject. Yah it was kinda easy because i knew what to do.

2. Did the unproject make you work harder than you usually would? Nope i always work hard on blogs and stuff like that.
3. What did you like best about the unproject? Puting music and other applications on it.
4. What would you change about the next unproject? I don't really no wat i could.

5. Did the unproject make you learn more because you were doing a different type of project.

B.O.B

Hey
Alright this unit was alright i got the adding,subtracting thing rilly fast. It sorta messed me up when we did the mutipling thingy but once i understood how to get it, ther was no problem. The LCD was easy 4 me.I did most of the work that was given. When we started to do the division paart that messed me up and i still sorta have trouble with it. Overall this unit was okay

  1. Did you like the unproject. -The unproject was alright I am just glad it is done
  2. Did the unproject make you work harder than you usually would? -Yes, it did make me work harder cuz i had to some in early and get it done
  3. What did you like best about the unproject? -The best part about the unproject is the finished product cuz atleast its done
  4. What would you change about the next unproject? -I would change how it a was made i could have made it better.....
  5. Did the unproject make you learn more because you were doing a different type of project. -Sorta i learnt how to use the computer better

SUBTRACTING FRACTIONS .

When you want to subtract fractions that are a mixed number you should convert the mixed number into an improper fraction, then subtract them as fractions.Heres an example 5 1/8 - 2/3 = ? .. convert the mixed number into an improper fraction. which is 41/8 find the most common denominator and that is 24. your fraction now is 123/24. SINCE 8 x 3 = 24 and 41 x 3 = 123. The other fraction is 16/24 because 8 x 2 = 16 and 8 x 3 = 24. Then subtract 123 from 16 and that equals 107/24.. if you want to convert it back to a mixed number you have to see how much 24 goes into 107 . which is 4 times, then how much remains and that would be 11. mixed fraction is 4 11/24...
If the fractions aren't in a mixed number.. heres the way to do it.
2/3 - 3/5 = 10/15 = 9/15 = 1/15 .. multiply the denominators by each other ( 5 x 3 =15) .. then cross multiply 2 x 5 = 10 and 3 x 3 = 9 .. fraction is now 10/15 and 9/15 then subtract 10 from 9 and that gives you 1/15 ..
If the fractions have different denominators
1) Find the least common denominator.
2) Find the equivalent fraction using this denominator.
3) Subtract the fractions, if you could reduce then you should.

Adding Fractions for dummies Author abdul .s

There are 3 Simple Steps to add fractions:

Step 1: Make sure the bottom numbers (the denominators) are the same

Step 2: Add the top numbers (the numerators). Put the answer over the the same denominator as in step 1

Step 3: Simplify the fraction.


Example 1:

1 + 1


4 4

Step 1. The bottom numbers are already the same. Go straight to step 2.

Step 2. Add the top numbers and put the answer over the same denominator:

1 + 1 = 1 + 1 = 2




4 4 4 4

Step 3. Simplify the fraction:

2 = 1


4 2

(If you are unsure of the last step see the equivalent fractions page)


Example 2:

1 + 1


3 6

Step 1. The bottom numbers are now different. We need to make them the same:

1 = 2


3 6

Step 2. Add the top numbers and put them over the same denominator:

2 + 1 = 2 + 1 = 3




6 6 6 6


Step 3. Simplify the fraction:

3 = 1


6 2

Adding Fractions with Different Denominators

To Add Fractions with different denominators:

  • Find the Lowest Common Denominator (LCD) of the fractions
  • Add in the new numbers to the fractions to have the LCD
  • Add the numerators of the fractions
  • Simplify the Fraction

Example: Find the Sum of 2/9 and 3/12

  • Determine the Greatest Common Factor of 9 and 12 which is 3
  • Either multiply the denominators and divide by the GCF (9*12=108, 108/3=36)
  • OR - Divide one of the denominators by the GCF and multiply the answer by the other denominator (9/3=3, 3*12=36)
  • Rename the fractions to use the Least Common Denominator(2/9=8/36, 3/12=9/36)
  • The result is 8/36 + 9/36
  • Add the numerators and put the sum over the LCD = 17/36
  • Simplify the fraction if possible. In this case it is not possible

Equivalent Fractions

Equivalent Fractions are fractions that are equal or have the same value. They both represent the same pieces.

They are either a multiple or a divisor.

-This is like a multiple, you have a pie. Your sharing it with your best friend. So, each of you get 1/2 of the pie. The 2 pieces of the pie are too big for you two to eat. So, you went and cut the 2 pieces into half. Now you both have 2/4.
-To find a multiple of a fraction, you multiply both the numerator and the denominator by the same number.
-Example: 2/4 x 5/5 = 10/20

-This is a divisor, you have a pie. It was cut into 4 pieces. You and your friend are going to share it. So, you get 2/4 and he gets 2/4. You put your 2 pieces together and realize you have 1/2 of the whole pie.
-To find a divisor of a fraction, divide both the numerator and denominator by the same number.
-Example: 50/60 divide by 10/10 = 5/6

Improper fraction

Definition: A fraction with a numerator larger than the denominator


How to convert a improper fraction to mixed
Step one: check how much the denominator can go into the numerator. Then put the whole number for the mixed as how many times the denominator can go into the numerator.
Step two:The remaining numbers are the numerator and the denominator stays the same.

Proper Fractions

Proper Fractions
Definition : A proper fraction is a fraction with a smaller numerator then denominator.

Names used in fractions:
numerator - is the number to the left of the line. In the fraction 7/8 the numerator is 7.
denominator - is the number to the right of the line. In the fraction 7/8 the denominator is 8.

















Proportional Fractions - At the beginning of this page we defined the word fraction as a portion of the whole. We have shown that there is more than one way to write the portion that is half of the pizza. One half can be written as 4/8, 2/4 or 1/2. We say that these equivalent fractions are proportional fractions because they are the same portion of the pizza. Here are some different examples of proportional fractions using the integer bars. All of them are equivalent.

(Yes I know this is VVVVVVVVVVVVEEEEEEEEEEEEERRRRRRRRRRRRRYYYYYYYYY late, but I need it for my portfolio! =D)

This unit (percentages) was alright, a little challenging, but good. Most of the work was easy. The hard thing was trying to place the fractions from the fraction lines to X.K.Y charts. >> I absolutely STUNK at doubling and reducing size. I know I did bad last term. xD

Thursday, February 22, 2007

Wiki thing

Mr. H
I went in at lunch and finished all of the question and answers but when i cheeked it at home its was all screwed up so it would be kool if u can fix that for me cuz i dont no what happened.

wes

Monday, February 12, 2007

I found this unit pretty easy, i think the ratio tables were the easiest for me but i got confused by the xky charts.
I think i should start doing more of my homework to help me understand it a little more.
I also had trouble doubling the area of a shape, and i think doing those warm up things at the beginning helped me.
I think i understood the proportion word problems when i did them.

Saturday, February 10, 2007

Bob

I think this unit was pretty cool, I learned a lots. The easiest thing for me was the part and total. The hardest thing for me was doing those xky charts. And I found out the white booklet a little tough.I think i did good in this term but i need to improve on doing my homework.

Cumulative Question 6

(6) Jacob has a record of winning 2 boxing matches for every 5 he loses. If he had 49 matches during the last year, how many did he win?

This questioned was changed yesterday in class if no one can remember.

First you must do this:
Favourable Outcome

----------------------- (<-this meaning a fraction line)

Total Possible Outcomes

Out of every 7, Jacob wins 2. So... 2/7

Now we have to find out how many times he's won out of his 49 matches.

7 goes into 49 7 times.




There's your answer.






APRILP - CUMULATIVE QUESTION #1

You have a notebook of 23 sheets of paper; and 3 of them are black. A page falls from your notebook; what is the probability it was a black sheet?

3/23
(3 is the favourable outcome and 23 is the total possible outcome)

3 divided by 23 = 0.13%

The probably it being a black sheet is 13%

Thursday, February 08, 2007

Josh's Cumulative Question # 7

Christina practices figure skating an average of15 hours per week.

Kayla practices figure skating an average of 1.5 hours for every hour Christina practices.

How many hours a week does Kayla practice?

Since Christina practices 15 hours a week and Kayla practices 1.5 hours (90 min.) for every hour Christina practices all you should have to do is multiply 90 x 15 = 1350 min. ( 22 hours and 30 min.)

Christina = 60 x 15 = 900 divided by 60 = 15 hours a week

Kayla = 90 x 15 = 1350 divided by 60 = 22 hours and 30 min. a week

Bob

I thought this unit was hard at the beginning. The easiest thing for me to understand was the ratio tables. The xky charts were difficult at first but I think I came around and got used to doing them. Doubling the area of a shape was confusing for me. I am getting better at it but still not perfect. I may still need some help in certain areas in math but I think I will get it over time.

APRIL'S BOB and cumulative questions

(5)
What is 20% of 156?
to find this answer you divide 156 by 100 and multiply it by 20 to get 20% of 156
156 (divide) 100 = 1.56 X 20 = 31.2
31.2 = 20% of 156
the fraction would be
31.2/156 = 20/100

30 is 29% of what number?
divide 30 by 29 , then multiply that answer by 100
30 (divide) 29 = 1.03 X 100 = 103
the fraction would be
30/103 = 29/100

In this math unit I've learned alot even though there were times where I was so frustrated on what to divide and multiply and that stuff. I had a hard time with doubling the area of a shape I still dont get it that much right now but i'll learn on the way. The X K Y charts and the ratio tables were a bit comfusing at first but as i started working on them they became a piece of cake.

Qtypies's Question 3

The police have cornered this criminal in a small 23 home community. If they have only 46 hours to find him, and they can fully search one house in 2 hours and 23 mintues, will they find him?

So first you want to change the time to one unit. So if you change it to minutes then 2 hours and 23 minutes will be 143 minutes and 46 hours would be 2760 minutes.
Math work:

converting 2 hours and 23 minutes to minutes









Converting 46 hours to minutes
60 x 46=2760
60 is 1 hour and 46 is how much time they have
Conclusion
Math work:

2760/143= 19.30( rounded 19)
no, the police won't find him. because there is 23 houses and in my answer above it calculates to 19.30(19) so they will only fully search 19 houses in 46 hours.
Please leave comments behind on what i did wrong and other things!

Kimmie's Post for Question 5

Question 5 number 3 and 4

3) 44 is what percent of 62.

44 / 62 = .7096 * 100 = 70.96%

4) 55%of 26 is what number?

26 / 100 = 0.26 * 55 = 14.3%

Francis post for question 12

(12) Dave interviewed a number of students in his school regarding their favorite ice cream. Dave claimed that exactly 40% of the 37 students interviewed liked vanilla the best. Is it possible to determine whether David's claim is correct? Why or why not?

40/100 14.8/37
40/100x37=14.8

It is not possible that David's claim is right because 40% equals to 14.8 out of 37 people and there cant be a person that is .8 .

At the beginning of the unit it was a little hard but after I understood it, it was all easy. I learnt how to use x k y charts because i've never heard of one before. The hardest part of this unit was learning how to double the area of a shape. I still have a few problems with it. The easiest part of this unit was solving word problems, because im good at x k y charts and the t charts. Overall I think i did pretty well on this unit.

abduls question thingy

(6) Jacob has a record of winning
2 boxing matches for every 5 he loses. If he had 49 matches during the last year, how many did he win?
answer:
He won 14 matches out of 49.
To get this answer you have to add the total number of matches. He won 2 and lost 5 so the total is seven. To figure out the answer you have to divide 7 by 49 which is 7. Then multiply 7 by 2 which is 14. That is your answer

During this math unit, there's been a lot of confusion for me. First of all, I had a hard time trying to understand that " funny tic-tac-toe looking thing " which was actually the X K Y chart. But then I started working on it a little more. Plus, my group members were always helping each other out so that made things a little easier. The easy part was working on the charts. The hard part would probably be doubling the area of a shape. I learned a lot in this unit.

BOB Proportion Reasoning

As we did this unit it took me a long time to understand what we were learning. I learned how to use a X,K,Y chart and a ratio table and how to solve proportion word problems. I think the hardest part of this unit was how to double the area of a shape. I also found the white booklet was a bit easy as I started to understand what I was doing. Overall, I think I did a pretty good job in this unit.

I think this unit took a very long time to get through, but i learned a lot of things. The easiest thing for me was the part and total, and the x k y charts. The hardest thing was doubling the area of a shape without quadroupling it. I also found the white booklet a little hard. Overall, I'd say I did alright, but sometimes I didn't do my homeowork.

This unit was hard at the beginning, but once we worked on it. All of the work got easier and it made more sense to me. I would say that the blue booklet was the easiest thing out of this whole unit. The easiest thing in the blue booklet was the percents part and the page with the word problems on it. We learned how to make “xky” charts and “part and total” table; I find that the ratio table was the easiest to do. The white book was probably the hardest, but once I asked for help from people in my group it got easier and I finally knew what I was doing. I hope that I would do better in the next unit and term.

BOB

I think that this unit was hard,confusing and kept me learning all at the same time. I struggled for most part of the unit. The easiest thing of this unit was the House Proportions project or unit. The hardest part was the "XKY" charts and the ratio tables because they were confusing at first. I think that on the "XKY" charts and the ratio tables because I was doing good on that. For me on the unit I think I have to better on this unit and the others to come. I think that I did well in this unit, I hope... .

-Chris

BOB .!

In this unit I learned about "xky charts", and "ratio tables".

The parts that felt easy for me to do on this unit was the assignments in the blue booklet. I did well on the percent parts of this booklet where we had to shade in the percent.

The parts that felt hard for me to do on this unit was on some parts of the white booklet and the "part and total charts". Thanks to the help of some students that I got the hang of it.

In the next unit I'll try doing better and try to finish my assignments before the next math class.

Well for math i thought i did okAY. i COULD' VE DONE BETTER. bUT I ALSO THOGHT I'VE LEANED ALOT. iN CLASS I ALWAYS TRY MY BEST AND TRY TO UNDERSTAND. THE LAST QUIZ THAT WE GOT I THINK I DID PRETTY WELL ON THAT . aT THE BEGINNING OF THIS UNIT IT WAS HARD FOR ME TO GET USE TO IT BUT NOW I THINK I GET. BUT I STIL NEED HELP.

I think this unit was a little too long. I think that I did good for the most part of this unit. The easiest thing in this unit was the blue booklet.The hardest thing was learning how to use the "XKY" and the "Part Total" charts but once I learned it, it wasn't so hard. I think that I am doing well this term and I hope to keep it up.

During this unit I learned how to make xky charts and proportion tables. i first found this unit hard and complicated to follow because there were so many things to learn, but when mr h explained things step-by-step i got a better understandings of it.

My favorite part of this unit are the xky charts; they seemed a little easier for me to do because all the information is there to see. also i enjoyed doing the blue booklet mr h gave us. it was easy and fun. it wasnt a pain to do it for homework. xD

i found the white booklet pretty hard. some of the questions were simple and easy while others were complicated and long. also a lot of the questions had something to do about "looking for lenghts" and i wasnt sure how to that either. i asked for help and i eventualy started to get a hang of it.

amalia's 5 questions

Today in class Mr. H gave the class a sheet of paper with 20 math problems. Frances and i had volunteerd to do at least 5 different problems.


question 7.
David read 40 pages of a book in 50 minutes. How many pages should he be able to read in 80 minutes?
Well the answer i got and solved it goes like this, So what i did was that I had divided 50
pages 40 x 80 / 40 = 1.25 x 80 = 100.
_____ = / _______
minutes 50 100


Questoin 17.
If three apples cost 29cents , how much do 45 apples cost?

Well i solved the way i had answer goe like this. How i got this answer is by dividing 29/3=

Proportion Unit

I learned a lot during this unit. At first, I had no idea why do we have to use ratio tables and "x" "k" "y" charts. I learned that these two strategies helped to solve problems with no happy numbers :(
These two strategies are exactly the same as answering a problem with two equivalent fractions. The numbers are all the same it's just where you put them. Overall this unit was pretty easy.

I think that this unit was a long stretch for my mind. I think that I did good for the most part of this unit.
The easiest thing in this unit was the blue booklet.The hardest thing was learning how to use the "XKY" and the "Part Total" charts but once I learned it, it wasn't so hard. I think that I am doing well this term and I hope to keep it up.

BoBby lee

I learned a lot of stuff this term. I learned ratios,percents,decimals and x k y charts and porportion table.I found nothing hard because i listen so much ,but i complain alot.I found that every thing easy once i started to get it.I liked using x k y charts and porportion charts. I hated all of the homwork and thats it. I like math its better than la, social and every other coarse.

BOB

I learned a lot of things threw out this unit. What i liked about this unit is making the p/t charts. The hard thing was doing the x,k,y charts because i still have a little trouble. But the hardest thing was where you had to times is by 2 but instead people times it by 4.

In the next unit i will try harder and listen and finish my homework.

MR H

I think that this unit was a long stretch for my mind. I think that I struggle for the most part of this unit. The easiest thing in this unit was the number lines in the blue booklet and the shading in the percent. The hardest part of this unit was learning how to use the "XKY" charts but now I know understnad how to do them. I think that I really have to try a bit harder. For me that how my unit went...i hope that I do better for the next unit.

Today in class we did questions and learnt about an upcoming assignment.
Questions we did in class :

Question 4:

Question 5:
If 25 DVD Rom cost $14.50, calculate the cost of 11 DVD Rom

I solved it using word ratios. 11 DVDs would cost $126.
DVDs 25 x.44 11
Cost $14.50 x.44 $126

Question 6:
If 5 tickets for a play cost $40, calculate the cost of:
6 tickets
14 tickets
20 tickets

I also solved this question using a word ratio. 6 tickets would cost $48, 15 would cost $112, and 20 would cost $160

5X8 = 40
6X8 = 48
14X8 = 112
20X8 = 160

We also learnt a bit about an assignment coming up that we will be doing on the internet later. Its a sheet of questions we'll have to answer later on.
