A Few Words About MATH


Here we offer a sample of what we are learning in math. We found out that writing about math can be as challenging as doing math!

Commutative property - by the unknown Head

Changing the order of the addends or factors does not change the sum or product!
Some examples are:

9+3=12

5+6=11

4 x 2=8

3+9=12

6+5=11

2 x 4=8


Hey, it's not too bad in here!


Inventing a story problem to go with the equation 12 + Unknown = 18.

X and Y Coordinates
By Daija and Eli

Point x and y marks the spot!!! Our article is about the x and y coordinates. An orderd pair is just a pair of numbers. The x scale is the horizontal direction. The y scale is the vertical direction. The vertical line runs up and down and the horizontal line goes side to side. The first number you move is horizontal. The second number moves vertical.

If we had a bunch of orderd numbers and we had to connect them we would have a line graph. We would have a line graph because if we had to connect them together with dots and lines you would see if it is going vertical or horizontal. Like if you were tracking money and if you made alot it would go up. Here are some resons why we should learn this is because it can give information for keeping track or raising profit. Next, it can help children for going on field tripes by colecting money. Next, it can be used for getting new school supplies.

Calculators and Triangles by Jordan S and Emily
Calculators and Triangles!!! This story is about calculators and triangles. There are
three angles in a triangle and if you add all of the degrees in the angles you get 180 degrees. To find out the missing angle of a triangle you add the 90 and the 45 and you get 135. Next you subtract 135 from 180 and you get 45 ,So the missing number is 45. This is how you use a calculator . First you press the on button. Next you type in the numbers, then you press the plus button. Next you press the equal button , then you get your answer to the triangle. A triangle with all equal sides and angles is an equilateral triangle. The angles on an equilateral triangle would have to be 60, 60, and 60. Try it yourself!


Pattern Block Puzzles by Jordan I. and JuWan
Pattern blocks have pretty colors!!! Our story is about pattern block puzzles. We learned using pattern block puzzles on January 15. We used a trapezoid and a little triangle to make a three-sided figure with three angles because it is a bigger triangle. On a trapezoid two sides are parallel and two sides are intersecting if you drew the lines longer. A rhombus may look like it is intersecting, but it isn't. A rhombus is slanted but it is parallel either way. Two trapezoids make a hexagon because if you put the bottoms of two trapezoids together you get a hexagon.

 

 

 

How to Multiply - by Jordan S and Lashelle

Multiplying is very fun! Our story is about How To Multiply. Look at our problem. The problem is 12 x 12. Here are the steps!
(1.) 2 x 2 =4
(2.) 2 x 1 =2
(3.) shift over and put a zero under the four.
(4.) 1 x 2 =2
(5.) 1 x 1 =1 (
(6.) Draw a line and add the 24 and the 120 so you should get 144.

 

We knew the answer to the problem this before we did this problem. Students should already know the problem 12 x 12 becaues it is a special square. You will use multiplcation when you grow up with your money that you will get when you get a job to know if you buy some stuff from Wal-Mart so no one will rip you offf. Jordan was ripped off at a garage sale.

 

 

How to Divide - by Eli

Let's get ready to divide!!!!! To do division you must know how to multiply. For example will 5 go into 1? no. but will it go into 14? yes. How many times? 2 so you put the 2 above the 4 then you multiply by 5 and that answer is ten. So you put the ten under the 14.

Next you subtract and get 4. Then you drop the zero. Will 5 go into 40? Yes it will go into 40 eight times. Then you put the 40 under the other 40 and subtract. And the whole problem's answer is 28. The divisor is the 5 or the number in front of the division line.

 

 

I think when I grow up I will use division for lots of things.

 

 


Using Protractors by Aushalique and Justin
How do you measure corners? A protractor is for measuring angles. A protractor is shaped like half of a circle and it has numbers on the protractor. The numbers on the protractor go 0 to 180. You put the protractor on the lines that come together. All the angles in a triangles are less. You get the number 180 degrees when you add all of them up."I think parents should use protractors to build houses because you would not be able to get the corners strait" Kyrell said.

Math Patterns by Allen and Levi

The story is about the math patterns. Last week we studied patterns. For a example there can be letter, numbers or shapes. The pattern I know is abc cab abc cab abc cab abc. Here is one of our patterns we want you to solve. 2 4 8 10 __ __ __ __ __ good luck for solving our pattern.

 

Square Root by Shelby and Chelsea
Our story is going to be about square roots. A number times itself makes a perfect square for an example 4 times 4 = 16 because 4 goes into 16 4 times. If we were to draw a picture of a number multiplied by itself by using little circles we would describe it like this. We would see 4 circles in a row across the top and bottom. And 4 circles in a column going down on the sides. A square root is another sign for what times itself is the answer to the number that is already down in the square root. The square root of 25 is 5. The square root of 36 is 6 because 6 goes into 36 6 times. What is the square root of 144?

 

 

Algebra by Kyrell and Molly

We are learning algebra, It is fun! A math variable is a n, x or a shape that stands for an unknown number and it changes because another number changes. We used triangles, sqaures and circles to stand for an unknown number. Mr. Smith said that when we do math problems like that it's called Algebra. A triangle plus a triangle equals 10 so a triangle equals 5. So if triangle times square equals thirty then you take the 5 from the last problem because it's all one big problem and the square is a 6 because 5x6=30 and the answer is thirty. Algebra is really good for your brain because you will use this in your life when your older.

 

Pictographs
by Glen and Chelsey
The bar graph is different because it has bars and the pictograph has pictures. The most important thing to look at on a pictograph is the key because you've got to now what to count by. You have to have a title so you know what it is about. If you have 19 birds and they all equal 2 you would draw 9 and a half pictures.

 

Congruent and Similar by Travis and Chelsea
We were studying math when we were learning Congruent and similar. Congruent means that it has to be the same size and same shape. Similar means that it has to be the same shape. We colored the ones that are the same size and same shap blue because they are Congruent. The ones that just are the same shape we color yellow because they are Similar. There were the same circels on the sheet and the same Hexagon on the sheet too. there were big and littel similar Triangle and congruent Hexagons. It was easy because Mr. Smith explained it to us when he was teaching. We listened to the teacher that's how we know it is easy.


Lines of Symmetry By Matt and Kyrell
Do you know what a line of symmetry is? A line of symmetry is when we draw a shape and then cut it out. We use our rulers. When we cut it out we had to draw a line and then we put line of symmetry. A ball has line of symmetry and a butterfly does too. We have to put the line in the middle so they both are equal. The letter "A" has a line of symmetry up and down.


 
Math Combinations by Brant and Allen

A combination is how many sets of thing you can make of other things. For an example we had a red shirt and green shirt and yellow pants and black pants and white pants. So we could see how many sets we could make. 

We found 6 combinations you could wear of the shirts and pants. RS-WP, RS-GP, RS-YP, GS-WP, GS-YP, GS-BP.For the cars we found 12 combinations. For the animals we found 30 combinations.
