Jocelyn's Term two reflection

This term we learned about percents. Percents were alright they weren't the greatest but I could at least understand what I have to do in order to do good on percents in the final exam. We also learned about surface area and volume. Surface area and volume are sort of similar but surface area you want to find the area of the whole shape, where as volume you only have to find the "inside" area. I struggled with both of these when we first started these units because it was sort of new to me but now I get the hang of it and I understand it better. Math was definitely not the best subject this term but I'm going to work twice as hard so that I'm able to complete assignments and get good test marks.

Jocelyn's great book of Integers

Chapter 1 :

-3-(-7)=4

-3-7=-10

3-7=-4

3+7=10

Chapter 2:

Multiplying Integers

(+2) x (+3)= 6
(+2) x (-3)= -6



(-2) x (+3)= -6

(-2) x (-3)= 6

(+2) x (+3) = 6

(+2) x (-3) = -6

(-2) x (+3) = -6

-2) x (-3) = 6

ODD- If there are an odd amount of negative numbers(-) the product will be NEGATIVE

EVEN- If there are an even amount of negative numbers(-) the product will be POSITIVE

Chapter 3:

The same rule applies for Dividing integers

Dividing Integers


(+2) x (+3)= 6


(+2) x (-3)= -6

(-2) x (+3)= -6

(-2) x(-3)= 6

(+2) x (+3)= 6

(+2) x (-3)= -6

(-2) x (+3)= -6

(-2) x (-3)= 6




Chapter 4:
Order of Operations with Integers



Steps to solve (+5) x (-3) + (-6) ÷ (+3)=
1. Put square brackets around the operation that has to be done first (multiplication, division) 2. Solve the problem in the brackets and add the rest of the problem using the new number from the"brackets" 3. Next step is the same if there are anymore multiplication or division signs left 4.If there are no more multiplaction or division signs then you could finish by solving the rest of the problem using the addition and subtraction signs

Jocelyn Leclaire Percent Video Post

A percent can be very useful in our life today. If we didn't have a percents in our life, our lives and business would be just horrible! It would be confusing, and well just plain out dufficult. One of the ways and the most easiest way to figure out a percent is to figure out the "silver bullet" as Mr.Harbeck calls it of a number.

Cylinder & Volume Post.

Height = 10cm
Diameter = 20.3cm

r= d/2 r = 20.3 / 2
r = 10.5cm

v = π x r x r x h
v = 3.14 x 10.15 x 10.15
v = 323.49cm2
v = 323.49 x 10
v = 3234.9cm3

Height = 10m
Diameter = 0.8 (inside) and 1 (outside)

Inside -
R = d/2
R = 0.8/2
R = 0.4

V = π x r x r x h
V = 3.14 x 0.4 x 0.4 x h
V = 0.5 x 10
V = 5m

Outside -
R = d/2
R = 1/2
R = 0.5

V = π x r x r x h
V = 3.14 x 0.5 x 0.5 x h
V = 0.78 x 10
V = 7.8m

Final Percent Post Jocelyn Leclaire

In the chapter of Percents, Mr.Harbeck has taught me many things. He taught me that Percents are basically needed in the society of ours. He taught me about taxes, he taught me math and even some things about the real world! We learned about adding percents, estimate percents and like I said finding the tax on items and many other things in this unit.

Definition : A percent is a way to express a number into a fraction of a hundred.

Jocelyn leclaire's pay it forward

Jocelyn Leclaire's Pay it Forward!!

Part 1:What is pay it forward?

Pay it forward is doing a good deed for someone and expecting nothing in return. All the grade 8's watched a movie called "Pay It Forward". It was about a little boy named Trevor that gets assigned an assignment to try and change the world. Trevor helps the homeless, his teacher and one of his classmates.



Part 2: What I Did to pay it forward

I gave hampers to families that aren't able to have a christmas dinner or don't have presents for their children. The families that I helped have kids that go to Tec Voc and Know my auntie,which helped with this project by finding kids at her school, that aren't able to have a good christmas. I chose this project because I know that their are alot of kids at schools that have families that aren't able to afford food or presents and because my auntie works at Tec Voc, I thought that it would be better knowing that she could ask kids that she knows are going through tough times.We both donated together, which means that I got someone to pay it forward.

Part:3 What happened when I payed it forward

I know that I did a good deed because of the reactions that I got when I gave the families the hampers. The first family wasn't caught up on paying bills and couldn't afford food, so my aunt and I gave them a hamper and they started to cry in joy. The second family is dealing with the fact the father had just past away and when they recieved the hamper from us they were very appreciative by saying thank you and smiling. The third family had four children, no money, food , or clothes so my Family gave clothes that don't fit us anymore and we also gave them a food hamper with a $50 gift certificate for the Bay.

Part 4: Why is paying it forward important?

Paying it forward is important because the little things we do can change a persons life. I believe that what I did for pay it forward will have an impact on these families I helped because I payed it forward to them, they might do the same for others. Pay it forward could help the world change, if everyone did a little deed for someone else, creating a chain reaction that will spread, making many peoples lives easier.

Scribe 5.

I have to do questions number: 18 and 20 and 22 on page 86.

Alright, let's get started. (:

Question #18.




If you can't really see that, the question states.
A floor mat for gymnastics is a square with a side length of 14. What is the area of the floor mat in square meters?
One of the methods that you can use to find this problem out is:
Drawing it.



So, It said a side length is 14, right.
So we would show it like this:

So.
This is the formula to find the area

.

If you can not read that, or unable to read that.

The formula is:

SxS=A
14x14=196

196=Area

A=Area.

S=Side.

So the answer to question 18. -

A floor mat for gymnastics is a square with a side length of 14. What is the area of the floor mat in square meters?

is - 196 metres squared.

Question 20:

If you don't like how it says. It states:

Adam’s uncle has instructions for building

a shed. One page of the instructions,

shown below, is not very clear.

a) What is the area of the rectangle?

b) What is the side length of the square?

The formula to get the area is :

Or in another form.:

SxS=A

4x9=36

36=A

A=Area
S=Side.

What is the area of a square:

The area of a square is: 6 cm

Question 22:

If you can't read that , it says :

The world’s largest city square is

Tiananmen Square in Beijing, China.

It has an area of 396 900 m2.

a) What are the dimensions of the square?

b) If the square had dimensions of 629 m

by 629 m, what would be the area?

c) If the square had an area less than

394 000 m2 and greater than

386 000 m2, what are all of the

possible whole number dimensions

that it could have?

I looked and looked and asked many questions, but I do not know how to get the dimensions, I am very sorry about this, but I can not find it anywhere, I am very very sorry.

Jocelyn's math profile

I tell people that I like math. The best part of math that I did was learning about the french fries because it was funny and it makes me more interested in math. My best unit was integers because it was easy for me to understand. I struggled with my blog stuff. I could not struggle as much by keeping my brother off the computer. I will stay focused and keep up with all my work.
