FINDING "B" in a TRIANGLE

I volunteered to make the scribe for "FINDING B". Our lesson in math now makes me so interested about it. Honestly, for the first time, I understood our lesson and I was amazed that I was'nt struggling anymore!!! I really payed attention to it because I really wanted to learn. And now, here I'am scribing and sharing all the things that I know to find the "B" in a triangle.

To be able to find the "B", you MUST know the FORMULA first:

After knowing the formula, you now have to FIND the "B". Look at the triangle below. It shows that "B" is ?.

*Please get a piece of looseleaf. Try to find the "B" in the picture given below.

Good job for you if you did it right!!! But if you don't, its alright, just try your best next time. Here is the proper way of substituting. You may copy if you wish.

So, that means that "B" is equals to 17.3 cm.

Thank you for participating and hopefully that you learned something. Also, thank you very much for this opportunity.

How to find "A" in a Right Triangle =)

Yesterday (05.09) and today (05.10), we learned "Finding A,B, and C in a Right Triangle"


I am assigned to scribe about "Finding A." Follow along with this steps:

1.) For you to be able to find the missing side which is A, you must know the formula first:


2.) To begin with, you must know what the given numbers are:

Now you know that:
(Hypotenuse) C = 10
(Base) B = 6
(Altitude) A = ?

3.) Once you've gathered information, we begin to substitute:


--
Hope this helped you though it's short. It's really easy! But you MUST ALWAYS know what the formulas are for you to be able to substitute all the way to the answer. Refer to your foldable paper, it's a good source for reviews!

How to find "A" in a Right Triangle by Andrea Tria, 817 =)

Boeun's Scribe Post 04/17/07

Today in class (day 6 - period 6),
we corrected our blue sheets and got our homework. (blue sheet).

What we corrected (blue sheet):
LEGO
TRIANGLES (OR DIAMONDS)
I AM AN UPSIDE DOWN L

I'm explaining the LEGO one.

1. Draw out the next two patterns in the space below.

This is the answer for the question #1



Well, I can't actually explain you this right now. There isn't enough information. Let's go to the question #2.


2. Make a table to show the results of your investigation.



This is question 2. The answer is right below. =)



Here are my explanation:

The pattern is that the x row is starting at 1, getting larger by 1, and also in the numerical order. You could also see that the y row starts at 6, getting larger by 3 and the multiples of 3. This could be the answer for the question 3, which says to describe the patterns found in each row.

3. Describe the patterns found in each row.

x row
- starts at 1
- increases by 1
- numerical order

y row
- starts at 6
- increases by 3
- multiples of 3

Now, it's time to explain question 3B.

3B. Describe why the patterns increase the way that they do.

- The pattern increases by 3 because you are adding 3 legos to the edge to create the next figure.

My explanation is exactly the same as my answer for the question 3B.

4. Describe the relationship between the two columns.

- y is larger
- you have to add (+) or multiply (x)
- three times (figure #) plus 3
- 3n + 3


Here is my T chart.



4C. Write an algebraic equation to show this relation ship.

n = figure #
3n + 3

5. Predict what the 20th, 35th, and 99th diagram will look like.
(DO NOT PANIC)

20th -
n= FIGURE NUMBER
3n + 3 =
3(20) + 3 =
60 + 3 = 63
63 = 63

35th -
n= FIGURE NUMBER
3n + 3 =
3(35) + 3 =
105 + 3 = 108
108 = 108

99th -
n= FIGURE NUMBER
3n + 3 =
3(99) + 3 =
297 + 3 = 300
300 = 300

6. Predict which diagram will use 30, 50 and 125 blocks.
(Well, you have to change 50 into 51, change 125 into 126)

30 legos -
n= FIGURE NUMBER
3n + 3 =
3(9) + 3 =
27 + 3 = 30
30 = 30

51 legos -
n= FIGURE NUMBER
3n + 3 =
3(16) + 3 =
48 + 3 = 51
51 = 51

126 legos -
n= FIGURE NUMBER
3n + 3 =
3(41) + 3 =
123 + 3 = 126
126 + 126

For this question, as the questions says, you have to predict. Sometimes it takes long time to predict. There is short cut. Mr. Harbeck will teach us someday.^^
For example, let's figure out 30 legos.

n = figure number

3n + 3 = 30
......- 3.....- 3
3n = 27
..............27/3 = 9
3(9) = 27
27 = 27

This is a correct way to solve this kind of problems.

FINALLY THE LAST QUESTION! =)

7. Make a graph for the first 6 terms and label the line according by it's equation.

You have to make a graph for this question.



HOME WORK:

Today's homework is to finish up 2 blue sheets.
One is called Pyramid power and the other one is called Build me a house #2

This is just to show the pictures together.

I'm finally done and I hope you actually understand it.

Please comment if you want me to change something. Thanks. =)

2. Make a table to show the results of your investigation.



3. Describe the patterns found in each row.
x = Gets larger by 1
= Numerical order
= Consecutive numbers
= Starts with one

y = Gets larger by 2
= All odd numbers
= Starts with 2

3.B. Describe why the patterns increase the way that they do.
-The pattern starts at 3 because it takes three tooth picks to create a triangle.
-It then goes up by 2 because there is already 1 triangle and you're just sharing a tooth pick.
-They are all odd numbers because...

4. Describe the relationship between the two columns.
= y is larger
= We have to + or x
= figure + figure + 1
= 2 times figure + 1
= 2n + 1
= n = figure #

4.C. Write an algebraic equation to show this relationship.
= n = figure #

2n + 1 =
2(30) + 1 =
60 + 1 =

5. Predict the 20th, 35th, and 99th diagram will look like.

n = figure #

20th -
2n + 1 =
2(20) + 1 =
40 + 1 =
41




35th -
2n + 1 =
2(25) + 1 =
50 + 1 =
51




99th -
2n + 1 =
2(99) + 1 =
198 + 1 =
199



6. Predict which diagram will use 31, 51, and 125 tooth picks.
2n + 1 = tooth picks

31 tooth picks -
2n + 1 = 31
2(15) + 1 = 31
30 + 1 = 31
31


51 tooth picks -
2n + 1 = 51
2(25) + 1 = 51
50 + 1 = 51
51



125 tooth picks -
2n + 1 = 125
2(62) + 1 = 125
124 + 1 = 125

Well fraction is kinda hard for me because you have to do the converting fraction and the reducing fraction... and I don't even know how to do it ...... so now I know how to do it because I always paying attention and I always focusing my work..... so when the test come, I am able to answer all the questions... and specially I practice it by answering the PURPLE BOOKLET... so the purple booklet is a big help to me. It help me to practice in addition, subtraction, multiplication, division, LCD , equivalent fraction and etc. Learning this thing could be apply to the lessons we will be learning in grade 9 and i am glad that they teach me this kind of topic.

THE UNPROJECT:

1. Did you like the unproject.
- I enjoyed doing the unproject, because I get to work with a partner.

2. Did the unproject make you work harder than you usually would?
- Well some of the question we didn't get it, but me and my partner we try our best to finish our work

3. What did you like best about the unproject?
- By doing the designing thing.. just like the glowing words on the wiki.

4. What would you change about the next unproject?
- I would put videos, and make it better.

5. Did the unproject make you learn more because you were doing a different type of project.
- I learn a lot of thing about fraction just like the reducing fraction and the converting fraction... before I don't know how to do the converting and reducing but now I really know how to do it and I am proud to myself.

Rina's Bob

In this unit, the easiest thing that I learned was adding and subtracting fractions. It was easy for me to understand and I got some help from my friends. The purple book helped me on how to add, subtract, devide and mulitply fractions. The hardest thing that I learned in this unit was deviding fractions and a little bit of multiplication. It took me a while to learn because I didn't really understand it very well, but my friends helped me. My goal for the next unit is probably to listen more so I can understand easily what I am being tought.

For the unproject, the best thing that I liked the most was was the backround information on all the different kinds of fractions. I liked this part the best because it was the easiest part, and I had the information about it on my big paper.

orange and green =)

Junebe's BOB

Fractions:
This grade eight unit of fractions wasn't that difficult for me. I sort of get fractions but the word problems I don't really understand. In word problems I get confused because I think its either multiplying, dividing, adding, or subtracting. The most easiest thing I learned this unit about fractions is multiplying. I think multiplying is the easiest, because I like it when I cross reduction it. My goal this year is to practice my word problems.

The Unproject
For the Unproject my partner was Rivka. We did a slide show explaining about Adding, and subtracting fractions. The thing that I like best for doing this project is when I was searching for pictures, and example questions. The part that I disliked about the project is NOTHING.! lol well I think thats all I have to saaay. LAATERZ

Maxine's BOB

So I found fractions a piece of cake. Though I did find word problems a little challenging. First we learned about all the types of fractions. Out of the four there are, proper, improper, mixed, equivalent and lowest common denominator. We made a big paper on these topics, mine is completed. Then we learned to add, subtract, multiply, and divide fractions. I found this all a piece of cake too. To help us we had to do pages on the purple booklet for homework or practise. I always did my homework, that's why I get it. On the purple booklet I was stumped on a few word problems but I got them after. I just get mixed up when it comes to dividing or multiplying in a word problem.

Unproject
Well I had the bestest partner ever, CJ. We sang a song about topic #1. Which is about fractions. I think we did very well and we deserve a good mark. We did all the background information you need to know and our song is awsome, though I made like one major mistake and Mr. Harbeck said we could cut and paste stuff to delete it but nope, so you can laugh at my mistake because so do I. What I liked best about this project was practising singing the song. I had so much laughs with CJ. And I'll admit this project was a little harder than most of our assignments and CJ and I finished the night before so yea... and if I had to change anything about the next project I would change the marking rubric. SO THAT SLACKERS CAN'T GET GOOD MARKS!! Because it ain't fair! Different type of project definately and it did make me learn more because I had to know about it a whole lot to help with the lyrics. And did I like this project? Yessir!

Michael's Bob

To me fractions are alright for me. I know most of the things you have to do like converting fractions and reducing fractions. I had some trouble with this fraction unit but I would of been able to understand everything if I actully tried during school, not being lazy and pay more attention during class. The things that helped me learn this unit was by doing my purple book and my big paper.


I wasn't a big fan on doing the unassighnment. Actully, im not even done doing my project so it's late right now and I guess I lost a quite a bit of marks. The only thing i liked about while doing the unassighnment was making up the questions. This project was harder than all the others we've done so far because i decided to work alone without a partner so I had to do all of the work myself.



*michael alohhaa*

Paola's bob (fractions)

fractions for me is no prob!since i studied it in my elementary years. But when the word problem came in the scene(test), this is what makes me sooooo!!confused!I don't know how to solve it since there is no mathematical signs on it, instead they used words. so i focused on working in word problem. i practice it by answering the PURPLE BOOKLET!
PURPLE BOOKLET is a big help to me. It help me to practice in addition, subtraction, multiplication, division, LCD , equivalent fraction etc. Learning this thing could be apply to the lessons we will be learning in grade 9 and i am glad that they teach you this kind of topic.

The Unproject
This is the most fun unproject i ever did!!!!we chose to do a song, Camille and Me. I also enjoyed watching and seeing the unprojects of the other students from my class and from different class. The personal background is like doing a scribe because you put all the things you've learned in fractions and putting slides. I think that in this way of making projects, it would be easy and a big help for students like me to learn the topic but in different way that students are not only learning but also enjoying.

JOREL'S BOB

Fraction is kind of easy to me though I don't like it because you need to take so many step at some problems. Sometimes you need to convert, or reduce and stuff. But its still easy for me. But sometimes some of the question confuses me especially the word problems. I don't like word problems. OH YEAH we did an unproject.

I don't really like the unproject because I don't use wikispaces much. I really work hard on this harder than usual. The one I like best about the unproject is the one where I searched the definitions of some words like fractions, proper fractions, mixed number, etc. I guess next time I'll put the picture with the definition rather than putting it in a seperate link. I didn't really learn anything more when I look at the unproject because I already know all of them. I already learn all of them.

BOB fractions

fractions??? uh i think i started learning about fractions when i was in grade 1. but i strated learning adding, subtracting, multipying and dividing fractions when i was in grade 4. but i forgot all about it, like i forgot how to do it. anyway, in this unit, i learned about fractions again (kinds of fractions, how to add, subtract, multiply and divide fractions). when we started doing the 1st page on the purple booklet, i thought that i wouldnt be able to understand on how to do those things, but i actually do understand it. i have struggled in some of our quizes because i really get confuse of some fractions especially when it comes to adding and subtracting fractions. well, the purple booklet really helped me to understand everything. for me, i really think that i did a great job, because im not really having some problems in this term not like before.

lets talk about the unproject thingy, well i really had a great time working with my partner which is junebe. well the project that we did was a slide. we did it because we thought that was the easiest. in our project, we explained about our topic, our topic was adding and subtracting fractions. we also put some examples in each slides. its kind of hard though, especially when draw some pictures on paint =). but yeah, atleast me and junbe have done something and we really gave lots of efforts doing that. well i think thats all i can say about our project.


oh yeah!! thanks mr henley and mr harbeck for helping and teaching us about fractions!=)

Shawn's BOB

Personally, i didn't like the unassignment, actually, i didn't like the unproject at all. Well, there was one thing i liked and it was making the pictures, but putting the info wasnt all the great either. The unproject sure did make me work harder than all other assignments we did, but thanks to jake being there and helping me, he cut down the work.

What i liked best about the unproject was like i said, making the pictures because it helped me to use other programs to make the diagrams for our unproject. What i would change about the next unproject, is that i would choose a different selection for the choices we had to choose from. Like a video for example, it would be a great experience ;P. The unproject didn't really make me learn more about fractions because i was doing a different type of project because i think fractions are easy because my grade 6 teacher taught us well on fractions and i carried it to grade 7 and 8, so i think doing this unproject didn't really make me learn more, but it made me work harder.

tgeeehh boy this is SHAWN

Andrea's Fractions B.O.B. =)

Fractions. When I first heard that we're going to talk about fractions in Math Class, I first thought it's going to be easy. Because fractions are somewhat introduced to regular students at like, Grade 3. But half way through the lesson, I found some things complicated, like the borrowing part.

But of course, by listening attentively, the borrowing part is as easy as pie. It's just hard when you first look at it. And I find word problems really tricky. Thanks to the purple booklet! I practiced solving word problems in different types: addition, subtraction, multiplication, and division. The best part for me is the multiplying and dividing fractions. The things is, back in my elementary days, finding the LCD and cross-reductions became really hard for me. But now, I find it really easy and somehow very interesting.

The Unproject. I liked (and I still do!) the idea of the unproject because I think it's a very unique and smart way to show our knowledge and creativity. Different students picked different kinds of projects. Some did a movie, a song, and an animation. Depends on how they want their own abilities to be seen. I, myself, did a quiz that would be good for reviewing. When Mr. Harbeck announced that we're going to have unprojects, I was really weirded/freaked out because I thought it's really, really hard to do. But when I tried, I got really busy. Just so when I realized that the unproject isn't really that hard (I just had it inside my head), you just have to give it your all. It really got me all worked up because I was thinking that I was on my own, and I have nobody to rely on but myself. Though I actually didn't start the unproject until Spring Break's over (lazy bum!). But I'm pretty surprised that it turned out a lot better than I've expected :) But next time, I'll try to have my unproject done before the night of the due date, so I won't have to rush or stay up all night doing the unproject.

See for yourselves! Here's a link to my Wiki Unproject (though this is linked to my Background Info. Just click the link there to navigate to my actual unproject):

Janna's Blogging on Blogger a.k.a B.O.B

Fractions Unit:
Our fraction unit was complicated. I did learn how to add and subtract same denominators in grade 5 but not multiplying or dividing or even finding the LCD. I got the adding and subtracting right away. I also understood the multiplying and dividing too, I just didn't know when to do in a word problem. I still get confused while doing some word problems. The Purple book helped me practice the four types of fractions as well as finding the L.C.D. I mostly had my work done in the purple book when it was assigned, Otherwise my work was always completed.

The UnAssignment:
I really had a fun time while doing my UnAssignment. My sister helped me out and we had many laughs together while filming the video. It definatly took a lot of time (9-11 hours)but in the end I'm happy how it came out. Although I didn't actually start the project until 2 days before the project was actually due (I have a very bad procrastination problem hehe) It still came along. It took a lot of takes before it was right. The UnProject didn;t make me work harder than I usually work because when it comes to projects and test I always work and study really, really hard. (Although, I still can't beat Jake) The thing that I liked best about the UnProject was spending time with my sister. It also kept the information fresh in my head. I kept repeating all of the information and now I don't think I'd be able to ever forget this stuff. The thing/s I would change about the next UnProject would me be starting the project sooner so I wouldn't be rushing to do it. I would also have thought out everything before filming because it wasted some time. The UnProject was definatly different than any other project that I've ever done before. So... Of course I learned a lot more than a normal project would teach me. Basicaly I learned how to use Windows Movie Maker and I got experiance in acting like Ellen DeGeneres and Oprah. Also maybe someday I'll have my own talkshow. Well actually no, I don't think I'd want one!

Thanks Mr. Harbeck and Mr. Hanley for teaching me some really cool stuff and also giving me a chance to do such a unique project such as the UnAssignment!!!

John's BOB

In this unit we learned about fractions, how to add, divide, multiply and subtract fractions. I learned how to convert improper to mixed fractions and how to convert mixed to improper fractions. After that Mr. Hanley gave us the purple booklet to work on. We have to finish every page as we go on to our lessons. It help me to understand fractions more and learned a lot. I still get confused on word problems because of that there is no symbol just words and numbers. Fractions wasn't that hard when you know what your doing.


Unproject Reflection
1. Did you like the unproject.
I enjoyed doing the unproject, because I get to work with a partner.

2. Did the unproject make you work harder than you usually would?
Yes, me and my partner did our best.

3. What did you like best about the unproject?
I like the part when it was finish and complete.

4. What would you change about the next unproject?
I would put videos, and make it better.

5. Did the unproject make you learn more because you were doing a different type of project.
I learn a lot from the unproject because I get to do fractions and put everything there is to know about fraction.
