Nino's Great Book of Integers

Chapter 1

Grade 7 Integer Review

(+4) + (-2) = +2
Positive (4) and Negative (2) = positive 2
have 4 and owe 2 = have 2
Standard Form: 4 - 2 = -2
Making zero pairs:

-16 = +16, -5 = + 5, +6 = -6, -2 = +2,

-10 = +10, +3 = -3, +11 = -11, -9 = +9

Chapter 2 Multiplying Integers

Sign Rule:
Even: When you have an even amount of Negative factors, the product is Positive.
Odd: When you have odd amount of Negative factors, the product is Negative.

(+2)x(-3)=
2 groups of (-3)= -6
- - -
- - -
(+2)x(+3)=
2 groups of (+3)= +6
+++
+++
(-2)x(+3)=
remove 2 groups of (+3)= -6
- - -
- - -
(-2)x(-3)=
remove 2 groups of (-3)= +6
+++
+++

Chapter 3 Dividing Integers

Sign Rule:
If you have no negative or an even amount of negative signs in a division question, the quotient is positive.

There are 2 types of division:

Partitive Division:
Making parts

EX:
6/2=3

6/-2=-3

Quotative Division:
Sharing you total with groups

EX:
(-6)/2=-3

(-6)/-2=+3

Chapter 4 Order of Operations

Brackets
Exponents
Division
Multiplication
Addition
Subtraction

(+5) x (-3) + (-6) / (+3) first you always follow BEDMAS so division is first in the question

after you do the multiplication and finally you do the addition.

example.

(+5) x (-3) + (-6) / (+3) = ( -17)

(+5) x (-3) + (-2)

(-15) + (-2)

(-17)

Term 2 Reflection

In term 2 I've learned a lot about 3 D Shapes and the formulas for finding there volumes and areas.
EX: Volume of Cylinder =Pi x Radius x Radius x Height, Area of Prisms = Length x Width, Volume of Rectangular Prism = Length x Width x Height. We also had to learn how to make nets, 3 D shapes.

I mostly struggled on the formulas because there were a lot of them and I had to remember all of them, but with some practice I finally remembered all of them.

Next term I will try to focus on my homework and study more about what we will learn. I will also try to get my grades higher and continue doing a good job on tests.

I've learned so much from term 2, that the surface area of a shape is the sum of all the areas and can and can determine the Surface Area and Volume of a 3 D shape. And that Volume is the amount of space a 3 D shape has, and probably a lot more about 3 D shapes.

Chapter 7.3


a)V=A of BxH
V=78.5cm2x23cm
V=1805.5cm3

A of B= pi x r x r
A of B= 3.14 x 5 x 5
A of B= 78.5cm2

b)V=A of BxH
V=615.44cm2x12cm
V=7385.28cm3

A of B= 78.5cm2
A of B= 3.14 x 14 x 14
A of B= 615.44cm2

c)V=A of BxH
V=0.785m2x1.5m
V=1.1775cm3

A of B= pi x r x r
A of B= 3.14 x 0.5 x 0.5
A of B= 0.785m2

Chapter 7.4



Inner Tube:

r=d/2
r=8/2
r=4cm

V= pi x r x r
V= 3.14 x 4 x 4
V= 2009.6cm3

Outer Tube:

r=d/2
r=10/2
r=5cm

V= pi x r x r
V= 3.14 x 5 x 5
V= 3140cm3

3140cm3 - 2009.6cm3 = 1130.4cm3

Winnipeg Harvest

During The Tour

When we got to the building we sat and a person from the Winnipeg Harvest told us about a bunch of stuff. He showed a map of where the different food banks were around Manitoba. The the top things that they needed were:

1. Canned Fish & Poultry
2.Canned Fruits & Vegetables
3.Canned Stew, Chili, Brown Beans
4.Baby Food
5.Whole Grain/Wheat Pasta
6.Peanut Butter
7.Rice
8.Canned Spaghetti Sauce
9.Cereal
10.Canned Soup

Who Do They Help?

The Winnipeg Harvest send food to the "Hungry" or poor people and people in poverty.
They get the food from kind people and also themselves. Stores that have food products that they do not need send a lot to Winnipeg Harvest.

During The Volunteer

When we were volunteering we had many boxes of canned food in a table and in another there are many big bags. Some people would stay in a table to put 3 different kinds of canned foods in a plastic bag and close them. On the other table when they send plastic bag full of canned, we would take 7 of the plastic bags and put them in 1 big bag and tape them shut. It was a lot of work but it was to help since we were doing it for the people.

Nino's Pay It Forward

Part 1:
In my thoughts, paying it forward means doing a random act of kindness knowing that you are getting nothing in return. Doing a random act of kindness can be giving your place in line for someone in seems in a rush or opening the door for someone who seems to be loaded with bags. Doing a random act of kindness will let people recognize how to do the same thing to other people which will lead to paying it forward.

Part 2:
My pay it forward act of kindness were helping people shovel their yard, donating to The Salvation Army, and putting up flyers around Brooklands School. We chose these activities because it seems helpful and fun at the same time. We helped people to shovel their yard and helped people who are in need with the donation. We shoveled people's yard, donate to The Salvation Army, and put flyers around Brooklands School. We did out act of kindness in December 18th, 19, and the 20th.



Part 3:
It went pretty smooth but it wasn't all fully groups. Everyone did their job and stuff but in different times. I felt good inside, knowing that I did a good cause in this community. They reacted suprise to see people like us helping them clean their yard up. We didn't really ask to pay it forward since we were kind of nervous.

Part 4:
The idea of paying it forward is important because it lets people be nice to another and to do the same thing to other people which will lead to paying it forward. We think it did since it will tell people to helpout one another and be nice to eachother.

Nino's, Math Profile

Hi my is Nino. To me math is kind of fun, but even better if the teacher is really funny. I actually like learning math, but not homework since we already have to do lots of work in school. I don't really like doing much work, because I also want to have fun. I really like solving because some of the problems are new to me, and you get learn the ways of it. Elementary was way different and much easier.

Last year, we did integers. It was easy, and we also used chips as an example on how use integers and the tests would be like free marks since it was so easy. I also liked areas of circles and squares, because we did the formulas and they were new to me. But I was kind of struggling on it since there were lots of formulas to remember.

This year I think I will do well on integers, since it's easy, but not on algebra. Algebra was kind of confusing and I did really do well on it last year, but this year i 'm going to try studying on it.

Last year when I was a blogger I got kind of confused on how make one, but the teacher helped me so I finished it on time. Blogging was actually kind of fun, and it felt good doing it for the first time.
