Video

Today we saw a video with 2 ?s about s.f., perimeter, and area. The video had an old man teaching us the opposite way, but he was really brilliant. He thought us the very long way to solve a problem. I was confused and so were other people. It was hard to understand, but I realized it was worth listening to. At last it all made sense to what he was saying. I already knew s.f., perimeter, and area, but when he was teaching us he made more work and good at teaching.

Scale Factor Questions

Today we had to write sentences about scale factor and our sentences needed to have very informative information. We needed to have vocabulary, why it is important, examples, and how you solve it.

Similar Figures, Proportions Scale Drawings

Today we reviewed some of the things Mr. Sudo already thought us. The things he already thought us were similar figures, proportions, and scale drawings. I learned that scale means a ratio between two sets of measurements. I also learned that similar figures means same shape not size as the short way to remember it. I also learned that proportions means two ratios must form equal. Everything will be used for the rest of the year. That is what I learned today.

Similar Figures and Triangles

Today we learned about mostly triangles and the definition for Similar Figures is
Similar Figures- Figures that have the same shape
     - Corresponding pairs of sides of similar figures that are proportional
The types of Triangles we learned today are
Isosceles- Tri. w/ congruent sides
Scalene- Tri. no congruent sides
Right- Tri. w/ a 90% angle
Obtuse- Tri. w/ 1 angle larger than 90%
Acute- Tri. where all angle's are less than 90%
Equal lateral- Tri. all sides are congruent
Today was a review for me. I already heard about all these triangles, but I might of not of known what the names of the triangles meant.                                                 (Tri means triangle)

S.F. Foldable

On Friday we did a foldable were we had to make it about S.F. I really did not know what to put on my foldable but then I remembered that i had all the information I needed in my notebook. I put the 8 ways to write a proportion, WBD DO, KHDmDCM, KFC, examples, and the definitions of similar and proportions. That is all I remember of what I put on my foldable.

Brain Pop Quiz

Today we took a quiz over S. F. I got a 7/10 which = 70, The ones I missed were the last 3 questions and now I know why I missed the questions. I did the calculations wrong in my mind. It was just because of 1 # that I missed that 1 question. I also read the the question wrong and I thought the S. F. was another #. Today we took a Quiz and went over every single question.

Similar and Scale Factor

Similar- Corresponding sides and not alike.
Today we had similar triangles. One triangle was bigger than the other. On 1 side of the big triangle their was a 4 and on the smaller triangle their was a 2. The scale factor was dividing by 2. On the big tri. there was a 9 & 6, and on the small tri. there was a X & a Y, so I divide it by 2 & got X=4.5 and Y=3 as my answer. I wasn't there for the rest of class so I don't know what happened the rest of class. THE END

Proportion and KHDmDCM

Today we did Pro. and that is when you put a number over a fraction bar and another number under it. This is suppose to help you understand a problem easier. Converting a measurement to another. Make the #'s bigger.
EX: 10cm/3m = 10cm/300cm = K l H l D l m l D l C l M
                                                     l     l     l 3  l  0 l 0 l
A Pro. is kind of a fraction and kind of not. Partly a fraction and partly not a fraction.
King                  Drinking
Henry   merely   Chocolate
Died                  Milk
Step1: Variable     Step2: Isolate     Step3: Diagnally Multiply
In problems for proportions you get to increase, decrease, use operations, you can use dilation and reduction.

Excel & S.F.

Today we learned how to do a excel. First you go to google docs & go to spreadsheet then it opens and you get started. We also learned S.F. which has a big and small shape. Their is a # on 1 side of a shape and on the other  similar shape on the same side their is a variable. Same thing on other sides. Then using the knowledge you know   you can figure out what the S.F. is. The S.F. is the number that you multiply with a number of a side to find the # of the other similar shape were the variable is.

WBD DO

Today we did What is Being Done Do the Opposite.
EX: 2x+8=9  WBD | DO
           -8         *2   | divide2
        2x=9-8    -8   |  +8
      2/2x= -1/2
         x=1/2

Coordinate

Today we learned about how to coordinate distance, but I already knew the stuff so I finished fast. We tried to figure out the distance in a park and we needed to put posters of something on the trees. 1cm = 100m and the first distance was 300m, but it didn't work. But we knew it was right so we went to the next problem. The next answer was 800m, but it still didn't work. By that time it was time to go, so we left without finishing. But I knew we3 were right.

Scientific Notation

On Friday we played a game were the computer spun the dice and there were three numbers. We could use any operation we wanted to get a number. We lost. Scientific Notation is when you either add zeros to make the number bigger or smaller. The answer will be a decimal. You can do the opposite.

EX: 3.45 x 10negative2nd = .0345

EX: .03/100 + .004/1000 + .0005/10000 = 3/100 + 1/250 + 1/2000 = 60/2000 + 8/2000 + 1/2000 = .0345
