Josef's Scribepost for December 3

Today in Math, we talk about square root in the foldables and our textbook.We need to answer questions : 6,9,11,13,15,17,19,20,21,22 and 25.

11)What is the square of each number?
a)9
-The square is 81. Because you multiply it by itself.9 squared or 9x9=81

b)11
-The square is 121. Because you multiply it by itself.11 squared or 11x11=121

17)A fridge magnet has an area of 54mm squared. Is 54 a perfect square? Use prime factorization to find the answer?

54

/ \
2 27
/ / \

2 3 9
/ / / \
2 x 3 x 3 x 3

54=2x3x3x3,54 is not a perfect square because it has an odd number of factor of 2 and 3

Vicky's Scribepost, December 2nd

Today in math Ms. Usiskin told us to do the questions in the text book, or we can finish our number line inside our foldables. I chose to do the number line.

Sorry for the super bad quality, the quality got bad when I put it in blogger... idk why. & sorry if the pictures are so small,if i made them any larger it would've been too blurry to see. I probably didn't complete this part of my foldable either. Sorry :)

Well, I didn't know what else to label, so thats all I could think of. Sorry if its so plain.

COMMENT PLEEASE ! :)

Today in Math class, Ms. Usiskin handed out are math quiz she graded it with letters:







Ms. Usiskin was talking about it for a bit, then we had to try to revise our quiz.



Then we started to go over the homework, which was the foldable on the numberline. Then after that we started to talk about "square roots". Which is the second flap in the first foldable.





sorri if i didn't say everything we did in class i kinda forgot.


THE HOMEWORK: Finish revising quiz and finish your number line (with fractions, with decimals and with your calculator) . REMEMBER to press SQUARE ROOT for the calculations.

Today on math most of us has to revise our quiz.

After that we started to work on our foldables.

- answer yesterday homework to fill fractions and decimals.

This is kinda what you need to have on your foldable at Square root section.>>>>>>>>>

Then we discussed about square roots, and how to get them in a calculator. Square roots, side measure of a square the number I can to get the area of a square.

After that we have homework to fill in the number line on our calculator. (with calculator)

Scribepost for November.30

Today to start off the class we had a simple quiz about Squares.

After that we started to work on our foldables.

We made a number line looking like the picture above on our yellow piece of paper , after that we talked to our parnters and tried to figured out different patterns that we saw showing on the number lines.
Patterns: The numbers between the perfect squares increase by 2

For homework you need to fill in what the next two numbers are.

Today in math we had a quiz.

The quiz was about squares it was pretty simple so most of you should've got it.

After the quiz we got to work on our foldable.

This is kinda what you need to have on the yellow part of the foldable >>>

Then we discussed with out partners patterns with the numbers bwetween the perfect square numbers. We found some patterns like the numbers between the perfect square increase by 2 and the spaces between the perfect square go up by 2.

After that we all had homework to fill in the little number line thing up to 16.

Have Fun :).

At math today we finish the "Building the Squares" and the chart.















As for Homework we did have to find how many perfect square can you make with 4 squares.

Sorry for being late.

Our homework was this:

We learned today that you can make squares by cutting the square.

we also added the other square to our square
It should now look like this:


now that we have that finished our chart should look like this now:

This is pretty much all we did in class

Sorry for being late

BUILDING SQUARES

the girl told us to cut out 2 perfect 10x10 squares and 2 10x8 squaresand 2 2x10 squares. Then he told us to colour the 2 10x10 squares . Then put a 10x8 square with a 2x10 square and colour it a different colour . Then we had to put the perfect 10x10 squares away and keep the 10x8 squares along with the 2x10 squares.

And after you need to glue the paper in the yellow sheet. Then right 0.1 beside the paper that you glued in the yellow paper.

To find the area of a square, you must square one of the sides.

E.g 2 squared = 4

Squaring a number means to multiply a number by itself.

In class, we had to find out what was the biggest square we could make with 2 squares.

I found out that a 1.4 by 1.4 square is the biggest square we could make. I had four squares left over.

Alexander's Post for November 16

What we did on November 16 was learn about prime factorization we had numbers like 164, 196, 150, and 225.

We also learned how to identify perfect squares. The prime numbers in a perfect square repeat themselves and can be divided evenly.


That is what we did that day, if I'm missing anything please tell me because that's all I can remember.

Jerick's scribe for november 20

On November 20 , 2009 we did more things on squares, factor trees and on our foldable.

These are the things we did on factor trees.





The thing i learned is that , you know a number is a perfect square when you are able to equally divide its prime factors .








This was the homework that was given...

You are supposed to make a perfect square with 2 tiles . Make a perfect square with 3 tiles and so on.
( you are allowed to cut the tiles to make smaller tiles)

Raquel's Scribe Post For Squares

Okay, so in math class on November 20 2009, we corrected the pages we did for homework in the Math Links Homework Book.The pages were 24 & 25. We corrected it by doing factor trees.

So, all we did was do factor trees for each question to show our work. We also wanted to find the prime number so we can determine if it is a perfect square. For example 3 x 2 x 3 x 2. These 4 numbers are prime factors. It is a perfect square because if the prime numbers can go into a number evenly.

After all that, we started working on our FOLDABLES-
So, in class you should of done the labeling already and so, all we did was we folded the paper in half after that, you fold the sides into the middle which will make 4 sections.
So, it will look like this.

The next thing we did was that we opened the part where it says " What I Need To Work On " and we put lines on the top and bottom section. After we have done that all we did was with a ruler we marked 2 cm which should be marked evenly. Then mark each tick 1 - how much ticks you have. After that we put in the 5 perfect squares.
" one= 12, four= 22, nine= 32, sixteen= 42, twenty-five= 52 "

That's it for the foldable. Now for the homework

HOMEWORK-
All we had to do is make a perfect square was 2 tiles, 3 tiles, 4 tiles and 5 tiles.

THE END. THAT'S ALL WE DID ON NOVEMBER 20, 2009 FOR MATH CLASS. ANYWHO, THANKS FOR READING AND COMMENT PLEASE IF YOU DON'T I'LL FIND YOU. (:

Prime Numbers and Prime Factors

What we did Today:

HOMEWORK QUESTIONS ANSWERS

Notes
What are factors?: A factor is a whole number which divides evenly into a whole number leaving no remainders. A whole number is a number without decimals in it like 2.50

What are prime numbers?: A prime number is a whole number greater than 1 that has only 2 factors: 1 & itself. 1 is not a prime number. Some examples are prime factors are 2,3,5,7,11,13.

What are prime factors?: Prime factors are factors that are prime numbers. In my words, its putting a whole number into its lowest prime numbers also known as Prime Factorization. A way to use this method is to use a Factor Tree. Lets use an example like the number 12. Find factors of 12 and put it into the lowest prime numbers you get. Here is an example of a factor tree for 12.

Prime numbers and prime facotrs.

What we have learned today:
1.) Square numbers (perfect squares) are the product of a whole number when it is multiplied to itself. Eg. 4= 2x2. Therefore 4 is a square number.

2.) Factors are whole numbers that divides evenly into a whole number, leaving no remainder.
Eg. Factors of 16:
1 2 4 8 16

3.) Prime numbers are whole numbers greater than one, that have only two factors, which is one (1) and itself.
Examples of prime numbers are 2, 3, 5, 7, 11.
PS: One (1) is NOT a prime number. Why? Because it only has one factor, which is itself.

4.) Prime factors are the least possible factors of a number; must always be a prime number. The Prime Factorization method is used to get the prime factors of a number. (factor tree)
Eg. 18
/\
9 2
/\ \
3 3 2 = Prime factors.

Richard 8-73 squeares and rectangle

1. First of all, the sides of the rectangle are not equal.

2.But they can be equal. And if there all equal you get a square.

3. So a square can be rectangle.

4.But a rectangle can't be a square.

If you want to find Perimeter you must follow all the steps i give you.

Example: Length of 8 and the Width with 6.

P=8+6+8+6
P=28

If you want to find Area you must also follow all the steps I give you

Example: Length of 8 and the Width of 6

A= L x W
A= 8L x 6W
A=48

Introduction to rectangles, perimeters, area

What Do We Know About Rectangles ?

- All 4 sides are not equal
- But they can be equal which is a square
- So a square is a rectangle
- But a rectangle can't be a square or is not a square

(Because square sides are all the same and equal , at the mean time at a rectangle only the length and length are the same and the width and width are the same)

Perimeter
-Perimeter is the space around an object or a shape (going around)
How Do We Get The Perimeter ?

We follow simple steps to find the perimeter :
P= s+s+s+s

eg. A rectangle has the length of 4 and the width of 5. What is the perimeter?
P=4+5+4+5= 18

Area
-Area is the space that is inside a shape or an object
How Do We Get Area ?

We follow a simple step to find area :
A=l(x)w(x)h

eg. A rectangle has the length of 4 , width of 5 , and height of 8. What is the area?
A=4(x)5(x)8
=160

After a brief introduction to what we know, we did some work with what we then learned

#Tiles Is it a square or no ? Area
1 yes 1
2 no 2
3 no 3
4 yes 4

Then for homework we had to do the following :

Side length of square Area of square
1 1
2 4
3 9
4 16
5 25
6 36
7 49
Reminder : The way we find the answers are just like the times table. n by n (nxn)
