Skills Assignment: Fractions


Pythagoras
Pythagoras: The greatest genius ever lived... A "uber" smart mathematician also philosopher from Greek. But, nobody knows for sure if he EVER existed because nobody has found any evidence about his existents.For this assignment we were also given a list of (important) vocabulary words;
- 1.Legs
- 2.Hypotenuse
- 3.R.A.T
- 4.Greek
- 5.Theorem
Hypotenuse: The longest side of the "right" triangle, and is the opposite side of the right angle.
R.A.T: Which is the meaning of Right Angle Triangle.
Greek: A person born or living in ancient or modern Greece.
Theorem: A formula or perhaps a theory that can be proved.
Also for this assignment we are suppost to explain the artifacts Mr. Harbeck had posted for us.

-Pythagorean Theorem (One of the artifacts)
This artifact is also known as a right triangle, or so R.A.T (Right Angle Triangle) The right triangle has a 90° angle, which is the little square inside the triangle in the corner. Together the triangle is in total 180°
Now, this artifact, as you can see is a plain square, The lines on each of the 4 sides show that each of those sides are equal to the others. This square has 2 right triangles, which looks like the first artifact. Also, this square has 4 90° angles... So, the angles equal to 360° To get that you go 90°x 4 = 360°These pictures/artifacts are linked and connected because it all just has to deal with his theorem called PYTHAGOREAN THEOREM, and PYTHAGORAS himself!
The vocabulary helped to explain the artifacts because... as I said, it all has to do with the theorem, and Pythagoras.
YES, we DO care about Pythagoras, and his theorem in grade 8 math because he created this formula.
c²- a²= b²
36= b²

Script;
Bill: Hey Alice
Alice: Hey Bill
Bill: What have you been up to lately? You seem a little down. Are you okay?
Alice: Not much. Just busy with school work and No I'm not okay. I'm having some problems with my math homework...and it seems hard.
Bill: Oh. Well, I'm pretty good at math...here, I will help you.
Alice: Well sure, it's algebra homework combining like terms and distributive property. I only have a couple questions I am not understanding. See here, look the question is n+3-5n+12.
Bill: Yes. It does seem a bit hard.
Bill: Okay, well, first of all what was the answer you got?
Alice: I got -6+15 but I am kind of confused with it all.
Bill: Okay, how did you get that answer?
Alice: Well, I combined like terms because there is more then one variable and constant and that just means there is more then one letter and integer. So, I put the variables together, the "n" and the "-5n" and then I just added them together which equaled "-6n". Then I put the constants together which is the +3 and +12 and that equaled 15.

Alice: And a variable by itself means one...am I right?
Bill: Well, yes sure, but I got something a bit different from what you got. My answer is -4n+15.
Alice: Wait, that doesn't make sense at all to me! How did you get that answer?
Bill: Well, okay here, I will explain.
Bill: First, I circled the variables which are "n" and -5n and then I circled the constants which are +3 and +12.
Bill: Next I grouped the variables and then the constants then I took "n" and subtracted -5n which equaled -4n, then I took 3 and 12 and added them together which gave me 15, so, that's how I got the answer.
Alice: OH! I guess I get it now but I still have one more question and it looks harder then the first.
Bill: Okay, what is the question then?
Alice: It is 2+4(3n+8) and I got 12n+10 for the answer.
Bill: Well, no but good try. You have to multiply 4 by 3n which us 12n and then you multiply 4 by 8 which is 32.
Bill: Then you would bring down the +2 and add it to 32.
Alice: So, the answer is 12+34?
Bill: Yes!!
Alice: Oh! I get it now! Thank you!
Bill: Anytime. I am glad I had the chance to help you understand.

Scribe Post October 30th.
So, Today in math we had a 10-15 minute integer test by the time the test was done and over with Mr Harbeck gave us a "green" booklet, and just told us to forget about the "yellow" booklet for now. Inside of the "green" booklet there is integer questions some with brackets: example: 11 - (8)= 3 aka.. ( ) Training Wheels, and some without the brackets. Also in class we were doing the integers in standard form which means (NO MORE TRAINING PANTS!!). (:

Correct Question: -4 -3= -7
Wrong Question: -4 - (-3)=7

7-(-12)+5(-2)
* make it into a addition question.
7+(+12)+5(+2)
here's a example :

okay well that's my scribe , oh and if I made a mistake well then I'm sorry (:
The Backyardigans Journey Through Integers (:

They once again went walking down the path. A few moments later a raccoon walk out from behind a bush and stoped right infront of them. As they drew closer to the raccoon it looked as if the raccoon was smiling at them. The raccoon said aloud and clear "Hi there, this is your second question", and looked at Austin. (-5)+(+7) said the raccoon. Austin looked down at the ground and saw 5 small rocks that would represent the negatives and 7 large rocks that would represent the positives, he thought of the rocks as "Chips". Austin shouted the answer is "+2"! The raccoon said excitedly "Terrific, that's correct, you may now follow through".

They were so excited they almost begun running down the path. Tasha yelled "look, its the next animal with our next question", and they rushed down the path. When they got near to the animal they could all see it was a fox. The fox said "Nice to see you, here is your third question", and the fox glanced at Tasha. (-15)+(+10) the fox said. Tasha invisioned a numberline in her head with the (-) negatives on the left, and the (+) positives on the right. She said in a questioning voice "-5". The fox immediately said "Yay! Good for you, now you may reach your fourth question."

They all started running at full speed down the path to know what the next question was going to be, and to see the next animal. They finally reached the animal and which the animal was a friendly bear. The bear said "Hello, I'm pleased to see you this far, here is your fourth question...hm..." The bear look at all of the backyardigans, and then pointed at Tyrone. (+6)+(-6) "here you go" said the bear. Tyrone mumbled "its a zero pair, so its "0"! he yelled! "Good job, now you better hurry along to see your next question" said the bear.

Will the backyardigans get to the magical castle and complete the task ?
TO BE CONTINUED ... (:

The End.. (:
Courtney's Measure of Central Tendency
- Arrange in ascending order.
- Add all the numbers.
- Then the number you got divide by.
how many numbers are in the data.
- With an outlier the mean is less accurate "average".
Median - Arrange in ascending order/numerical order.- Middle number in data.
- Great to use if there is an outlier.
Mode- Arrange the data in ascending order.
- There can be more then 1 mode.
Range- Arrange the data in ascending order.
- Subtract the smallest data from the largest number.
- Large range = outliers.

Here is a video of mean median and mode..
