Sargent Park 8-17 Math

Time for a new home

2006-09-06T20:18:00.000-05:00

With much regret and yet excitement the Sargent Park Math Zone has moved to a new site. The reasons for leaving are that Blogger in Beta is a much better service. Please continue to use this site to see what happened over my first year of blogging.

Former students I encourage you to continue to use you classroom blogs as a way to communicate with each other and the math blogging community.

I enjoyed it and am looking forward to seeing what will happen this year. Below you will find links to the new Math Class blogs for Sargent Park School. To the seven wonderful people who have subscribe to this blog. Come on over to the new site and continue the journey. Comments are always welcome and appreciated.

New Homes for.....

Sargent Park Math Zone This will be the new class hub. Students will find out what they need to do for Blogging assignments and have the ability to be interactive in their learning.

816 The new class blog for this classroom. Its 33 students will become members and have opportunties online to reach new levels of learning.

817 The new class blog for this classroom. Its 31 students will become members and have opportunties online to reach new levels of learning.

841 The new class blog for this classroom. Its 32 students will become members and have opportunties online to reach new levels of learning.

873 The new class blog for this classroom. Its 31 students will become members and have opportunties online to reach new levels of learning.

Students will also post to their classroom wiki to create A Grade 8 Math Guidebook. This is a new and exciting opportunity to create a manual of everything that they have learned. The students will include problems and solutions, their scribeposts and growing posts.

The Scribe Post Hall of Fame will be a place to showcase the best class scribes.

The Growing Post Hall of Fame will house the best Growing Posts that the students create.

I hope you take time to visit our new blogs.

Mr. Harbeck
Thanks for watching our journey..... but it ongoing

A new year Dawns

2006-08-30T09:42:00.000-05:00

It comes time to say good bye to some very terrific blogs. These blogs will remain alive as former students come back and reminisce about the previous year. I hope that this years students use these blogs as examples to help them with this years work. Good luck to my former students who now are in grade 9 and welcome the new group of grade 8's who will be learning math in new exciting ways.

The new class blogs for 2006 are

8-16
8-17
8-41
8-73

I would like to thank the students for being such excellent learners and using technology to enhance their learning. I could not have done this without them.

In class today we learned how to figure out what the "c" is in a triangle.If you are confused I"ll show you a picture.(this is all coming out of my head so I dont know if this is right).Why are we trying to find "C" you ask??? Well we are trying to find C to make life easier and to put more questions in our math exam AHAH jk. Harbeck told us a story about a person named Pythagoras and he was sailing a boat. He wanted to get to one place to another. Since it probably took long to get from point "A" to "B" he would have just cut through. Here is another picture if you dont get it. AND he needed to know how far it was or else he would pull some bermuda triangle on his crew and be lost forever. AHAHAH jk.

There now I will show you how to figure out what "C" is.

2. How are improper fractions and mixed numbers the same?

3. Find a website or blog that explains how to create equivalent fractions or write fractions in lowest terms. create a link to it and a brief description of what the site has to off.

- http://www.aaamath.com/fra.html

This site as alot to off oin fractions and lots of other things about fractions. You can also learned alot from all the different links in this website. ENJOY !!!

4. A) Write a word problem that involves adding these two fractions with denominators of fourths and thirds and your answer is an improper fraction.
B) Write a word problem that involves subtracting two mixed numbers.

Answer A : I took 3/4 of my money in the bank and took 2/3 of money from the bank the next day. How much money did I took fromt the bank all together?

Answer B : While I was walking I had 6 1/2 of paper in my pocket and I dropped 3 1/2 of it. How much paper do I have left in my pocket after the accident?

5. Go to three peoples growing posts and answer their fraction problems by leaving comments. one of the three people cannot be from your homework!!
The posts that I have visited : Annalyn , Dhonna, Laramae all from room 16

1. This shape is a square that has side lengths of 5 cm. This shape represents 5/6 of a total. Use this square to show what the fraction 9/5. You can use diagrams, words, symbols to show your understanding.(copy the picture into your post and change it as you see fit!!)

2. What happens when you multiply fractions? Use both a numerical and pictorial example to show our understanding of this concept.

MULTIPLYING FRACTIONS

THINGS TO REMEMBER:

The product will be less than what you started with.
multiply the numerator to numerator then multiply the denominator to the denominator
All whole numbers have only 1 part so they are written as 4/1 or 326/1
when multiplying mixed number change all mixed numbers into improper then multiply

Example:

3/4 x 4/5 = 12/ 20 or 3/5

Steps:

Multiply the numerator to numerator--> 3 x 4 = 12
Multiply denominator to denominator --> 4 x 5 = 20
change to lowest term if possible; if improper change to mixed number--> 12/20 or 3/5

MIXED NUMBER EXAMPLE:

3 1/2 x 5/6= 35/ 12 or 2 11/12

Steps :

change to improper --> 3 1/2 = 7/2
multiply --> 7/2 and 5/6 = 35/ 12 ; numerator to numerator; denominator to denominator
change it to mixed number again and in lowest term if possible -->35/12 or 2 11/12

3. Find a website or blog that shows you how to multiply fractions. Create a link to this fraction site (highlight a word you want to be a link, click the link button, paste your url into the pop up that appears). Be sure to leave a brief 3 sentence description to the site.

Site for multiplying fractions ; this site has a quick explanation on how to multiply fraction. Then there's a quiz that test your skills on multipling fractions. Try this site to know how fast your can multiply fraction. TRY and LEARN!!

4. What happens when you divide fractions? Use both a numerical and pictorial example to show our understanding of this concept.

DIVIDING FRACTIONS

" Yours is not to reason why? Just invert and multiply"

THINGS TO REMEMBER:

How many groups of _ are in_?
Invert the second number
Reciprocal- two numbers whose product is 1; example: 1/2 x 2/1 = 2/2 or 1
To divide by a fraction, multiply by its reciprocal
write the mixed numbers as improper fractions, then divide
Change to lowest term or mixed number if possible

Examples:

2/3 ÷ 1/5

Steps:

Invert or find the reciprocal of the second fraction --> 1/5 turns to 5/1
Change division to multiplication--> 2/3 x 5/1
Multiply--> 2/3 x 5/1= 10/ 1; numerator to numerator; denominator to denominator
Change to mixed number or lowest term if possible--> 10/1 or 1

Dividing with mixed numbers:

3 1/2 ÷ 1 2/3

Steps:

Change fractions to improper fractions -- > 7/2 ÷ 5/3
Invert or find the reciprocal of the second fraction--> 5/3 turns to 3/5
Change division to multiplication--> 7/2 x 3/5
Multiply--> 7/2 x 3/5= 21/10
Change to mixed number again and change it to lowest term if possible--> 21/ 10 or 2 1/10

5. Find a website or blog that shows you how to divide fractions. Create a link to this fraction site (highlight a word you want to be a link, click the link button, paste your url into the pop up that appears). Be sure to leave a brief 3 sentence description to the site.

Site for dividing fractions; this site has a brief explanation on how to divide fractions. this site has an activity on how to divide fraction. Try it and see how good you are in dividing fraction. TRY it and LEARN!!!

6. Choose 4 peoples post which deserve to be in a Growing Post Hall of Fame. You must choose 1 from each class. Give a brief description of why you chose that person's blog to highlight. Create a link to that person's post.

8-17--> Myla she did her post and explain her answers. Her answer is easy to understand. She did a very great visuals.

8-16--> Helen she did a very nice work on her post . She has a colourful post. She did a very nice explainations

8-41--> Jenny coz she explain her work and answer the qeustion that is being ask. She has a pretty nice illustrations

8-73--> Ingrid coz she did a very good job on her growing post. There's an animation posts. She answer all the question properly. Guess she really deserve to have her post be posted in the growing post hall of fame.

7. Create a word problem that involves fractions. The word problem should have a picture in it ( a garden with 4 equal parts etc.). Answer someone elses word problem with a link back to the origional question.

Henry bought 234 marbles at the Mini Store and put it in his bag. On his way to Jerry's house he didn't notice that 4/7 of his marbles were gone. When he arrived at Jerry house how many marbles were left?

Fraction growing post!!!!! OMG I'm actually doing this

2006-05-09T12:57:00.000-05:00

the diagram shows 11/13 that's 11 pieces out of 13 that you own !

Improper fractions and mixed numbers are the same because they equal each other

5 4/5 is an mixed number
29/5 is an improper fraction
to get 29/5 to 5 4/5 you times the denominater by the whole then add the numerator
5x5+4=29/5
to get 5 4/5 you must see how many times 30 can go into 5 and put what's left as the numerator 1/3=2/6=3/9 the all end up as 1/3 =) >>>>>>>>>:( GGGGGGGGGGGGRRRRRR
7/8+2/8 is a bad example...................
(Coffee break.....................................*slurping noises*.............................)
ok! 1/3 + 1/3 = 2/3 but if the denominator is different like...........................
1/3+3/6 you have to find something the denominators both go into
OMG i'm done part 1
(Coffee break......................................*slurping noises*...............................)

1)

2) improper fractions and mixed fractions ar the same because an improper fraction can be inverted into a mixed fraction and vise versa with the mixed farction.

3) http://www.lessontutor.com/sv1.html once you get there click on the Equivalent Fractions link and it will take you to a site that explains how to do it. for wrinting fractions in lowest terms just click on the Reducing Fractions to Simplest Form link and yah same thing read it follow get it in your brain... maybe.

4) B) if you had 1 whole and 1 half of a pizza and your friend ate a quarter of your pizza how many do you have left? (if this doesn't make sense im sorry case im so sleepy)
A) if you add 5/4 and 2/3 what will you get? (again sorry if it doesnt make sense too tired)

6)http://www.lessontutor.com/sv1.html. once you get there just click on the Fraction Addition link and it will take you to a site that tells you what to do. for the subtaction you just do the opposite of adding so its pretty easy.

BobBert likes melons. He bought 2 melons out of a package of 4. Jogurt also likes melons. Who wouldn't? Anyways, he buys 2 out of a package of 3. Their friend, Steak, is a neat freak and wants everything in wholes. BB and J (BobBert and Jogurt) want to give melons as a gift. They decide to add them:

2/3 + 2/4 (You find a common denomenator between both of them, which is 12)

2 x 4 = 8 + 2 x 3 = 6 8 + 6 = 14
3 x 4 = 12 + 4 x 3 = 12 12

So adding both packs of melons, they concluded that a case between them would be 12, and still have melons left over for their own, many, uses.

A fraction in lowest terms is a fraction that can't get any larger.

An improper fraction is a fraction that has a numerator larger than the denomenator. A mixed number is a fraction with a whole number

http://www.aaamath.com/fra.html

this site tells you all kinds of things that have to do with fractions. It tells you what are equivalent fractions and everything else in the grade eight coarse. This is a good site if you need help on fractions.

An ELF lost 3/4 of her JAM in the fridge and had 2/3 of her HAM missing. How much is this all together?

I lost 6 3/10 of my JAM to an ELF and won 2 1/2 back. How much jam does the elf still have?

Subtracting Fractions

subtracting fractions means you must need to create the same size parts or COMMON DENOMINATORS.

6/4 - 3/4 = 3/4

Becky's scribe
sorry it's late!

There are two parts to a fracton, there is the denominator and a numerator.

The denominator is the bottom part of a fraction It tells you how big or small the parts are

The numerator is the top part of a fraction. It says how many parts of the whole

If the numerator and the denominator are the same then you have 1 whole.
If the numerator is larger than the denominator than it is an improper fraction, or you have more than 1 whole.

(The first one is halfs the seccond is thirds, and the third is eighths)

As the denominator gets bigger the the equal parts get smaller

2006-04-25T20:52:00.000-05:00

Kay uhhhh in class we learned about Equivalent Fractions.

To make an equivalent fraction you have to break the denomenator into smaller piececs. 1/2 = 3/6. You have the same amount but different sizes.

To make an equivalent fraction you need to change the numerator and denomenator equally. Like so...

1.
volume = Length x Width x Height = 1120 x .5 = 560 x 4 = 2240 m³

3.
5 x 5 = 25
25 x 5 = 125
25 x 5 = 125

then you multiply each by 2 because there are six sides.
25(2) = 50cm²
125(2) = 250cm²
125(2) = +250 cm²
-------------
550cm²

3. If you have five 5 cm by 5 cm x 5 cm aluminum cubes and superglue them together in a row, what is the surface area of the resulting shape made by the five cubes?

One cube is 150 cm so for 5 cubes it will be 750 cm... How? because 150x5=750 cm

Note:
Sorry thats the only one i can answer. the other ones are confusing and my brain is hurting...Harbeck! i dont know im my answer is right... just tell me 2moroe if its right or wrong ok? bye

bonus question thingy

2006-04-20T19:27:00.000-05:00

1) 1120 x 4 x .5 = 2240 m 3

2) 3.14(.3)(.3)
=3.14(.09)
=0.2826 x 3 = 0.8478 cm 3

i think it will only take about 1 second because if you estimate the voloume of the cylinder is .08 m3

3)
2x25x4 = 200
5 x 5 x 2 = 50

200+50=250cm2

mr. harbeck i cant post pics it wont work...nd i dont noe if dis is corect cuz the way you change the cm into m is confusing me

2006-04-17T16:43:00.000-05:00

To find the volume of a triangular prisim you multiply the base times the height times the length then divide by 2. To find the total surface area of a triangular prisim youfind the area of the base, sides and triangles then add theses together.

Then he gave us some works to do...
he showed us more examples so that we could understand it more.
i guess i covered all the things we did today in class...
Next SCRIBE NICOLE

To find the area of a rectangle you have to multiply length times width

Formula: A= LxW

To find the area of a triangle you have to multiply base times height

Formula: A = 1/2 x b x h

Day 1

To find the area of a rectangle you multiply length times width. (Formula L x W = A) To find the area of a triangle you multiply base times height and divide it by 2. (Formula : B x H = A) The relationship between the triangle and a rectangle is the triangle will always be part of a rectangle. For example, two triangles equal a rectangle.

Day 2

On day two we worked on different shapes and parallelograms.

Rectangles and triangles

Parallelogram
To make a parallelogram from a rectangle you take a triangle from one end and stick it on the other end.

Surface area
To find the surface area it is helpfull to draw a picture. I dont think there are any shortcuts....but i'm probably wrong.

Triangular Prisim
To make a triangular prisim you need to know that a prisim has 5 sides. To make the prisim you just have to make triangles and rectangles then put them together. Your 2 triangles will be the front and back of your prisim and should be the same size, 4cm, by 5cm by 6cm. Now you make 3 rectangles. 1 of them will have the side lenght of 4cm and a depth of 10. Your second one will have side length of 5cm and a depth of 10. Your third one will have a side length of 6cm and a depth of 10.

the total surface area is found like this....

6x10=60
5x10=50
4x10=40
4x6/2=12
4x6/2=12
60+50+40+12+12=174
total surface are is 174cm.

DAY 1
1) The formula is length times width or L x W = A.

2) The formula is base times height divided by 2 or
B x H
____
2

3) The relationship of the area of a rectangle and triangle is that a triangle is always half of a rectangle

DAY 4

I think the shortcut is multiplying by 2.

Mr. Harbeck i've been trying to upload the rest of the pictures for hours and it won't go, so far i can only upload this one after so many tries i will try sending it to the school and if it can't i'll try again tomorow... oh yah and i don't really know if that is corect

March 14

1. The area of a rectangle is found by multiplying its length and width. The formula would look like this: l x w = A

2. The area of a triangle is found by multiplying its height by its base. To find the height of a triangle look for a right angle. Once you multiply the base and height you divide the total by 2. The formula looks like this:

The relationship between the area of a triangle and the area of a rectangle is that every triangle is half of a rectangle.

4. Complex Figures

5. To find the area of a parallelogram you need to find the height and multiply it by the base. this is different than a rectangle. In a rectangle you have the height and base (due to the right angles in each corner). You multiply lenght times width. Here are three pictures that shows the relationship between the rectangle and parallelogram.

Hello people. I was supposed to blog yesterday, but i didn't get to go on the computer so im doing it now... The mistakes i made were leaving the question blank, and muliplying wrong. In question 9, i said 5(3) was 20 instead of 15. And in questions 4 and 8, i didn't put a final answer. I tried solving, it and showed my work, but i did't finish it, so it was kind of blank. I didn't complete the question. Man! i know i could do better. Oh well, theres always room for improvement right?

P.S. Megs says hi from 41! muhahahaha... ha.... ha!

THE TEST

2006-03-08T17:33:00.000-06:00

hello people of 8-17 and beyond. this is my post. Today we had a test, and the only thing that was marked wrong was translating the word sentence to algebra.
instead of putting 2x+2=24 i put x(2)+2=24.
then i find out that some ppl had it marked right because harbeck wuz being nice. what the heck.

Great Job and extra Algebra Help

Today in class we made another Hamburger/Hotdog/whatever thingy. We covered Collecting like terms and most importantly, transposing.

Transposing is really easy once you learn.

6x + 5 = 2x +13

(From the notes)

"You transpose when there are variables on both sides of =

Move the variables to the left hand side (Letters Left)"

6x - 5 = 2x + 13
-2x +5 -2x +5

so that leaves...

4x = 18
/4 /4

then, you just do standard stuff, and your left with one variable and a number

x = 4.5 ! =D

TODAY IN CLASS

2006-02-23T18:38:00.000-06:00

Today in class we learned about...
solving distributive properties. I'm terribly sorry about forgetting my notes at school. I am going to try my best to explain this to you.

Distributive Property
3(x+6)- two terms inside the brackets
this means 3 groups of (x+6)
(x+6)

x+6
x+6
x+6
-----------
3x+18

When you look at the question: 5(x+7), it means 5(x)=5. Then 5(7)= 35.

If you get confused, you can write it out like this: x+7
x+7
x+7
x+7
x+7
------------
5x+35
That's what we learned in class today. I don't need any help on this because I get it. So ya. If you don't get it, you can always ask harbeck for help.

Collecting Like Terms

2006-02-22T21:36:00.000-06:00

Today in class, we talked about the magic of COLLECTING LIKE TERMS.(rainbow)

4x + 6x = 20

You would add like terms, to simplify;

4x + 6x (just add the numbers, because the variable will always be the same).

Now, with that you would cancle out, but what you do to one side, you must do to the other, So your left with one variable;

10x = 20

/10 /10

x = 2

Now, a bit harder;

5x - 3 + 4x = 24

add; 9x - 3 = 24

cancel; 9x - 3 = 24+3

/9 +3 /9

One variable left; x = 3

That's the just. Enjoy.

Collecting Like Terms

2006-02-20T16:32:00.000-06:00

Today in class we learned how to solve like term questions. Terms that have the same variable parts are like terms.

e.g 1. 3x + 7x = 40
Add 3+7 = 10
10x / 10 = 40 / 10
x = 4
3(4) + 7(4) = 40

When solving like terms, you always want 1 variable and 1 integer term on each side.

e.g 2. 4x + 6 - 2x - 9 = 9
4x - 2x + 6 - 9 = 9
2x / 2 - 3 = 9 + 3 / 2
+3
x = 12 / 2
x = 6

And for those of you who missed class today, we created a parent quiz, which your parent/parents will take at . We will be heading down to the lab to type it into our power point presentations. In total, there will be 11 slides for math, that will show things on exponents, 1 step algebra, and its rules. They are: Isolate the variable, cancel the integer, balance, cancel what is attached to the variable, balance, and substitute to check.
