Chapter 1: Grade 7 Integer Review:

Integers are "negative" and "positive" numbers. They can be represented as integer chips or on a number line. You get a "zero pair" when you have a negative and positive of the same number, example: -3 and +3 make 0.

Adding and subtracting integers:
(-3) + (+9) =
owe 3 have 9= +6

(+7) - (-9)
have 7 owe 9= 16

Chapter 2 multiplying integers:

Sign rules: When you have an even number of negative integers the answer is positive.
When you have an odd number of negative integers the answer is negative.

(3)x (7)= 21
3 groups of positive 7 the answer is positive 21
+++++++ +++++++ +++++++

(-4) x (+2)
remove 4 groups of positive 2
++ ++ ++ ++ = -- -- -- --
-- -- -- --


Chapter 3: Dividing Integers:

The way of reading the dividing integers is:
- How many groups of (a) are in (b)?
- How many (c)'s go into (d)?
(+9) ÷ (+3) =3

Partitive Division - The making of groups or parts.
(9) ÷ (3)=
+++ +++ +++
3 groups of positive 3

Quotative Division - Sharing with groups.

The quotient of the two integers with the same sign is "Positive".
The quotient of the two integers with the different sign is "Negative".

Chapter 4: Order of Operation

B.E.D.M.A.S. is used to do the order of operations for integers which stands for:

Brackets
Exponents
Division
Multiplication
Addition
Subtraction

(+7) x (-2) + (-9) ÷ (+8) =
[(+7) x (-2)] + [(14) ÷ (+2)] =
(-14) + (+7)= -7

Term 2 reflection

What I did in term 2?
In term 2 i learned about surface area, percent, and volume. I learned how to do them thanks to Mr . Harbeck our math teacher. He taught us everything we need to learned. I learned the formula of surface area of rectangle which is (2lhx2lwx2wh), triangle (bxh/2) , cylinder (2xπxrxr)+(πxrxrxh).I also learned formula of volume of a rectangle (lxwxh), triangle (bxh1/2xh2)
and cylinder (πxrxrxh).

Did you do all your work?
Yes, I did all my work but i didn’t finish some of my homework.

What will you do better next term?
I will try to finish all my homework and do better on tests and quizzes and improve my marks.

Jam's Math profile

Hi my name is Jam and I am a math student in grade 8.I am going to ask you if you like math and if your answer is yes I might agree with you, because there is time that confuses me. Formulas are math problems that confuses me a lot.

Last year we studied a lot in math not in Sargent park but in my old school. Mean, median and mode are what i like th most. They are easy for me to solve and I can remember them easily.

I will need to study hard this year because I want to be successful for this subject.

I want to learn about algebra and formula this year. I find them hard for me to solve because you need to solve letters and numbers at the same time.

I only did one blog last year and its about how to be successful on final test that student do. this year we might do more blogging than last year.It is good for the student like me learn more staff that are familiar to us but don't really understand.
