NUMBER FAMILY

NUMBER FAMILY

One day in Number Villa. There is two numbers. The one is the big number and other one is the thin number. They introduce each self. “Hay, my name is zero. I am nothing in the world. I don’t have reason to life a long time” said the thin number. The big number also introduces her self. “Hay, my name is one. Why you look very sad and why you said like that?”

Zero answer the one question while she is crying “hik.. hik.. Because if I add with other number like two, three or etc. I still do not exist. Hik... hik. Then when I multiple with other number. I am also does not exist”.

Because of the big number is very sad, so the thin number give motivation to him. He says that “don’t sad, zero. You are the part of whole number and integer number. You still have me. We can be family zero”

Zero is sadder. She says again “there is no one loves me, everyone hates me. Hik.. hik..”

One still gives motivation to Zero. She says again “I don’t hate you, I love you zero. You can be the part of our family”.

After few minutes, Zero asks to One “Are you sure. We can be family?’

“Of course Zero. From now we are family.” Said One. And they are hugging each other.

So finally Zero and One life together and they are always happy.

Earth Day Event

Earth day is one of the school events that held annually every March. One of the purposes of this event is to realize a sense of caring citizen of the school such as students, teacher, staff officer and parent to aware on earth. The theme of this event in this year is Consume, Aware and Tribute. After we use and consume everything from earth like food, electricity, oil, water and something like that, we should be aware and give something for our earth.  Because of that, we should be tribute something for earth by saving energy and reusing recyclable material. Besides that, in this event can be start from reuse activity that will invite parents, teacher, office staff and students to make recyclable material will be something useful. They will be work in-group consists of five students with their parent and one teacher or one office staff, each group minimal consists of ten peoples. After they do something useful from recyclable material, all group doing campaign in around school begin form school walk to the mayor officer and back to school again.  During the campaign each group bring their something useful that they needs before. After campaign, in school still there are games that related with concept of theme of this event.  Further information regarding this event we can see in a poster taped in the announcement board.

Zero and One

 There are two boys having talk in one of the room in Number Villa. They is Zero and One. Zero is feeling useless in family number. If he is adding with other number like one, two, and three and so on, the result is still that number not influence with him. Every number if multiple with him the result always zero.  Moreover, if every number divided by him then the result of course does not exist.  He said that if he is no reason to life. Because of that, he is very sad and crying. As the friends One, try to make cheer up his friends.

 After one hour ago, Number one said that if Number Zero also useful in Family Number, without Zero there will never be Number One hundred or two thousands.  Nevertheless, Zero still crying and said if number One always the best and everybody like him.  Number one also told to the Zero if number one always alone.  Zero said if he also alone and One said if they actually will not alone if they are always together. After Zero hear what One said he is smile and hugging One. After that moment, Zero aware if he has reason to life and he is not alone, he is has One as a friends.

Number Zero and Mr. One

One day, on the high building there was Number Zero. He looked so sad. Suddenly, he jumped from that building. Immediately, the ambulance rent him to the hospital. After a few hours Mr. One as a doctor came. He asked to number zero “Is there any problem?” and Number Zero said that he has a mathematics problem. After that, Number Zero told about his feeling. He said that he was nothing and he was not important thing, not like Mr. One because everyone wanted to be number-one. Immediately, Mr. One told to Number One “It is not true. Number one you have a something special, you mean something. You are the meeting point between x and y axis. We mean nothing without you. You never know about me. Actually, I am lonely in the word, because I am one.” After Mr. One told her feeling, number one felt that he is not alone. Every number has a special quality. He forgot that he is special like the other numbers. The last, Number One say thank you to Mr. One, and they were hugging each other.

Zero and one in an amusing tangent

            Once upon a time, there was a police that suddenly got a call from the Numberville apartment security officer. He told to the police that there was a number who was later known as zero will commit suicide by leaping from the upstairs apartment. The police still looked so curious and then asked to the security officer of what the reason behind that motivated zero took action like that. Shortly after that, the security officer told to the police that the reason is because zero has some problems in mathematics. The police looked so curious yet, but he didn’t want to spend any longer time by investigating the security officer only. In the meanwhile, he asked to his friend to send the wise number one out to the location where the incident took place because he thought that number one is expert enough to handle such things happen.

            10 minutes later, the wise number one arrived in the location where zero will commit suicide. Zero get shocked after knowing the number one behind him all of sudden. But, on the other hand the number one didn’t respond anything and just considered it as nothing happen. Shortly after that, the number one came closer to zero and asked about what problems happen to him actually. Without thinking twice, zero shared his problem to the number one in detail with no hesitation. He told that he got a lot of pain in mathematics. He blamed on his fate being number zero and felt like he is nothing because nobody wants to be with him. He said to the number one “you know right, whenever I tried to add myself in any group, they just stand up leaving me behind. Whenever I tried to get close with someone, I found that they just finally disappear. I’m really desperate having this kind of life and I think that I have no reason to live anymore. So, what? I’m definitely true with not existing and now I’m just going to kill myself.

            Suddenly, the number one shouted very loudly to zero to stop doing the silly thing at the moment. Zero stood directly paused and at the same time the number one seemed to be compassionately against zero’s story for just a moment. Later, he tried to break down some zero’s argument that consider himself as nobody that adequate to be proud of and definitely true with not existing. He convinced zero that he’s just the absence and there’s nothing to be ashamed of. Furthermore, the number one added some statements to the zero “you should be proud of being zero”. As known that some numbers are likely confused with their positions. Sometimes they turned to be negative and on the other time turned to be rational and then turned down right at. Don’t you think that you meant something? Without you there will no decimal point. You are special and persistently you have a crucial role to act as a place holder in a number line. You have to be confident. Everybody needs you, zero”.

            On the other hand, zero still cannot 100 % believe in what the number one said to him. He still eager resisted against the number one’s opinion and said “where do you know it is true, Mr. popular? Do you lie to me? Don’t you remember that you are the number one? You are loved by anyone, you are better than I am and I think you could never understand about my pain”. Suddenly, the number one looked so sad. He explained to zero that he could understand his pain very well because he also has the similar problem with zero. The number one talked to zero “Do you ever know how to be the lowliest and loneliest number? You may argue that I’m perfect number than anyone wants to get the number one. But, you don’t know that being number one is the saddest experience you will ever know. One is the lowliest and loneliest number you will ever do and it is always much worse than two, three, four and etc. So, can you also understand how much pain that I felt?”

            At the moment, zero immediately embraced the number one. But, what happen after that? The number one just disappear all of sudden. Zero forgot that he has not to do that. Zero felt remorseful and finally end its life by leaping from the upstairs apartment.

When I make a worksheet

After I tried making a worksheet in UET class yesterday, I have many ideas to make interesting worksheet for students.   Before that, when I made a worksheet I just write a question or problems that related with topic at the time. I did not show the figure or graph that can help students to understand the problems in the worksheet. Like my worksheet beside, it was show the figure that there are in daily life. That is show if the trigonometry is useful in daily life to calculate the high or length of the ladder.  But my instruction in that worksheet is not really clear and just a simple one. The question that I use in worksheet beside is not really problems in daily life that was just like calculate the high of the triangle. After I shared and seen my friend’s worksheet, I got many information again about making a worksheet. I can use the problems I daily lives like go to the market and buying something.  That is can guide students to think that the problems there are in daily life and we can use mathematics concept to solved that. And below I show the new worksheet about Pythagorean theorem.  I try to use a story to tell students the problems in the worksheet. and students should find the solution. In addition in the worksheet above are not the space for students to write the solution of the problems. For making simple I give students space in the paper of the worksheet so they can write their solution.

Ladder Problems

Joni and Johan were twins who like doing anything together. One day they want to paint a tower so they need a ladder. As the father, Mr. John wanted to buy two ladders for them. But, at the market, the price of a single ladder is very expensive and Mr. John could only buy one ladder because Mr. John has not enough money. Therefore, so Joni and Johan can Paint the tower together Mr. John bought a ladder and make the same ladder at home.

The Ladder is like the figure beside. The length of the spacing between rung of the ladder is 30 centimeter and the distance of the bottom rung with the rear pole is 1 meter. Mr. John could not measure the rear pole of the ladder because are too high, in the figure showed by white arrow. Can you help Mr. John to calculate the measure of the rear pole using Pythagoras Theorem that have we learned? Please explain your answer!

Buying a Car Worksheet

Actually there is none comment from friends about the worksheet, because I and my friends just look each others worksheet and there is not enough time for discuss about each worksheet when pair chat. 

But looking others and then trying the worksheet to my students, I have to revise it for making it's beautiful and meaningful. Firstly, I revised the directions because I think it better to make it step by step so the students will follow the instruction easily. Then I totally revised the story because there just a few information used from the story, so I put some information about credit and cash system. The last, I simply the questions because the basic information was explained at the story. 

My worksheet (Snake and Ladders)

In this activity, you must play snake and ladders until finish. After that you must answer the question in below

a.    How many second you need to finish this game?

b.    How many minutes you need to finish this game?

c.    How many hours you need to finish this game?

d.    How many second you need if you are in the third line till fifth line ?

e.    How many minute you need if you are in the forth line back to the first line ?

After that you must complete this table.

No	Hours	Minutes	Seconds
1	....	65	...
2	3	...	...
3	...	...	180
4	...	...	800
5	....	115	...

Creating new worksheet

Comment:

            Actually there is no correction from the lecture and also from my friends related with the problem in the worksheet. The lecture, namely miss. puti and also most of my friends in my class said that it’s good enough. Yes, I am grateful of it. Suddenly, I didn’t know what problem I should take into the worksheet. I had no idea at that time. Then, I just tried to think spontaneously. I was looking for some pictures and the other resources that could catch my attention first. I didn’t know why I chose those pictures. I was just interested in those pictures and I thought I can use those on my worksheet. Finally I put those on my worksheet and started creating a problem. It was nice, fun and unpredictable. I could create something new. No cheating and yes, I am satisfied with the result.

            In spite of it, there are still some corrections from my lecture related with the grammar that I used in the worksheet. I am grateful of it because my worksheet seems to be perfect now.

Note: These are some corrections from miss. puti. You can check the corrections out below. 

Before the correction:

In Annie Avantie’s boutique, there is still a special offer for buying some spring session dresses that are design by the two most famous designers, Raf and Dolce.

After the correction:

In Annie Avantie’s boutique, there is still a special offer for buying some spring session dresses that are designed by the two most famous designers, Raf and Dolce. 

Here, you can see the worksheet after the correction. I make the new one of it. Check this out :)

 

How to draw a graph of a quadratic equation

How to draw a graph of a quadratic equation.

1.     1. We must know the quadratic equation. y=x²+bx+c

2.     2. Find intersection point in y axis. When x=0  then y= a(0)²+b(0)+c and we get point (0,C)

3.      3. The intersection point in x axis. When y=0 then 0=x²+bx+c  and we get two point  (X₁,0) and (x₂,0)

4.     4.Using the equation of axis symmetry is the line  X= -b/2a

5.  5. Find the vertex of coordinate using the formula are (x,y) is equal to  (-b/2a, -D/4a). D = b²-4ac

6.     6.The last we draw the graph based on the point we found.  Example we found the point are (0,-8), (-2,0) and (4,0), 1, -9)

Graphing a Quadratic Function

1.    First of all you have to know that the equation of quadratic function is y=x² + qx + r.

2.    Mostly the quadratic function has intersection with x-axis and or y-axis. So you have to find it to make you easily draw the graph.

3.    You will get the x-axis intersection by substitute the function you have using y=0. Maybe you will get one point, two point or not both. If you didn’t get any point, it means that the graph is located under the x-axis or upper the x-axis without have intersection with the x-axis.

If you get one point, it means the point you get is the vertex of the graph. And if you get two points, it means the graph has two intersections with x-axis. Because the normally found is two points, let us use it to be example. We called the intersection point with (a,0) and (b,0)

4.    Find the y-axis intersection by substitute x=0 to the function. The meaning of y-axis intersection that you get is similar with the meaning of x-axis intersection. Because we already choose two intersection points at the x-axis intersection before, so the y-intersection is just one point. Let’s called it (0,c).

5.    The next step of graphing is finding the vertex. Vertex can be found by using formula. But don not worry if you forget the formula, you may use this step; use the x-axis or y-axis intersection to count the vertex, in case axis has two intersections point with the grapd. For instance, if you get two intersections at y-axis you have to use it. And if you get two intersections at x-axis, let’s use that point to find the vertex. In logic, when the graph passing through two point at x or y, the vertex coordinate of x-axis or y-axis will be located at the central of the two point. As I already say that we will use the two intersection of x-axis as example, so we have point a and b at x-axis. Count the differences of that two, and then divide it by two. We called the result x=d.

6.    Finding the x-coordinate of vertex, substitute the x=d for finding the y-vertex coordinate. Then call it y=e. Hence we have the vertex coordinate at (d,e)

7.    You already have points: (a,0), (b,0), (0,c), and (d,e). Try to figure out that point’s to the graph.

8.    If you still doubt about your graph, substitute independent x point or y point to the function so you will get another coordinate for accurate the graph. 

Step to draw a Graph of a Quadratic Function

Hello students.

Today we will learn how to make a graph of a quadratic function. Are you ready?

1st step
*) We should find the intersection points of x-axis and y-axis. We can find the intersection of x-axis if y = 0. And  we can find the intersection of y-axis if x = 0.

2nd step
*) This step will help us to find the minimum or the maximum point of a quadratic function. If we want to find the point, we can use (x,y) = ( b/2a , D/-4a ). Did you know what is variable D? This variable represent determinant. We could find determinant by the root of b square-4ac..

3rd step
*) After we find all points, draw the points into a Cartesian diagram and then, we have to make a line that connect each point that we find.

This is the manual step to draw a graph of a quadratic function. If we want to draw a graph using software, such as geogebra or maple. We only type our quadratic function into the command column, and after that the software will show us how the graph of the quadratic function.

Thank you.
