Poem "At the lesson"

I sit in class, staring at the ceiling.

When will the long-awaited bell ring?

I had no time to teach lessons,

Repeat paragraph one hundred and one again.

At first my brother and I played together,

Then I listened for a long time to "Jester with the King",

Then I watched the series for forty minutes,

Then I played football with Romka.

And the poor textbook lay on the shelf.

Only at nine o'clock I ran home.

But it was too late: I already wanted to sleep.

And here I am sitting at the desk in the lesson,

I can't find a solution to the problem

And, apparently, I'll get a deuce again

But I'm bad at math.

The mother will be upset, the father will scold,

Computer games will end...

Why did I walk so long yesterday?

It would be better to read the hundred and first paragraph:

It's time to change your attitude to learning!

And mathematics, friends, must be respected!

How much do you know

Secrets, riddles you will solve,

You will become more educated

Just don't be lazy.

Chorus: Ah, you learn the rules

Ah, the formulas are bison,

Ah, don't be lazy, repeat everything,

Ah, don't forget anything.

Well of course, well of course

If you're so lazy

If you're so cowardly

Nothing you want to know

Don't solve your problems

Do not solve an example for you

Will be a problem for you]

Learn mathematics.

1. In the history of science, it is customary to call HIM the first mathematician from the city of Miletus - a Greek merchant, traveler and philosopher (VII century BC). Of course, there are earlier Egyptian and Babylonian sources containing a variety of arithmetic and geometric information, but they do not even have a hint of evidence. The first mathematical theorems are attributed to HE (Diameter divides the circle in half, theorems on the equality of vertical angles, on the equality of angles at the base isosceles triangle etc.). He made a number of discoveries in the field of astronomy, set the time of the equinoxes and solstices, determined the length of the year. HE was numbered among the group of "seven wise men". 2. OH ​​(III century BC) - an ancient Greek mathematician, author of the work "Beginnings" in 13 books, which outlines the basics of geometry, number theory, a method for determining areas and volumes. He selflessly loved science and never allowed insincerity. One day the king asked him if there were more shortcut to know his work. To which he proudly replied that "there is no royal road in mathematics." In history Western world his book was published after the Bible largest number time and more studied.


A bit of history… 3. HE (VI century BC) – ancient Greek philosopher and mathematician, transformed mathematics from a collection of formulas and recipes into an abstract deductive science; he is credited with studying the properties of integers and proportions, proving the aspect ratio theorem right triangle. According to legend, in honor of the discovery of his famous theorem about the legs and hypotenuse, the scientist sacrificed 100 bulls. But later it turned out that this theorem was known to the ancient Sumerians. To date, about 150 proofs of this theorem are known. 4. OH () - Swiss mathematician, physicist, astronomer, worked in Russia and Germany. Contributed to number theory, geometry, mathematical analysis, deduced a theorem on the connection of edges, vertices and faces of a polyhedron. He made a great contribution to topology, a branch of geometry that studies the properties of a figure that does not change under continuous deformations.

Mathematical KVN

“We are not yet Archimedes…..”

(for 9th grade students)
Tasks:

Frontally repeat educational material mathematics;

develop logical thinking, speech, attention and memory;

Expand the horizons of students;

Cultivate an interest in mathematics.
Motto: "The road will be mastered by the one who walks, and mathematics by the thinker."
2 teams take part in the game: the "Radius" team (joyful, active, friendly, inventive, smart, courageous) and the "Figure" team (physical culture initiative, competent, skillful, cheerful, reckless).
Program:


  1. Team greetings.

  2. Warm up.

  3. Mathematical kaleidoscope.

  4. Captains competition.

  5. Competition "Who is more?"

  6. Homework(musical competition).

  7. Summing up the results of games, competitions KVN.

Between competitions musical breaks and contests with fans.

The whole game is evaluated by a jury, which includes teachers of mathematics and one representative each from the students of the class that participates in the game.
Event progress.


  1. Introduction by the teacher.

Music sounds - an introduction to the television game KVN.


Dear guests and participants of the game! Of course, you all know well this musical introduction to the KVN television game: “We are starting KVN - for whom, for what?...”

For whom are we starting KVN today? Of course, for you, my students. So that today you get a little distracted and have fun, get to know each other's talents and abilities better (and you have a lot of them), think about questions and answers, show solidarity with the teams, increase your intelligence, get infected with a sense of healthy excitement and competition, in general - time to good use.

And why are we starting KVN? So that none of you ask such a familiar question to all teachers of mathematics: “Why do I need mathematics? I won't need it in my life." The word "mathematics" came to us from ancient language: comes from the ancient Greek words "mathematice" and "mathema" - "knowledge, science." Mathematics is the science of quantitative relations and spatial forms of the real world. And if there are exercises for the development of the body, then mathematics is designed to develop logical thinking, attention, and train the brain. No wonder it is called “mind gymnastics”.

I want you to be convinced that mathematics is a wonderful, not dry science and that doing it is just as exciting as playing KVN.

So, we start KVN.

For all.

Question. This theorem is studied in high school and is called the "bride theorem". Formulate it.

Hints:


  1. The theorem is proved in the course of geometry and is considered one of the most important theorems of the course.

  2. The theorem is used at every step in the study of geometric questions.

  3. The scientist who formulated this theorem was born on the island of Samos. In his youth, he traveled around Egypt, lived in Babylon, where he had the opportunity for 12 years to study astronomy and astrology from the Chaldean priests.

  4. This scientist, in addition to this theorem, is credited with a number of remarkable discoveries, including the theorem on the sum of the interior angles of a triangle.

  5. Particular cases of this theorem were known to some other nations even before its discovery.

  6. In construction practice, the Egyptians used the so-called "Egyptian triangle" - a triangle with sides 3, 4, 5. (The Egyptians knew that the indicated triangle is rectangular and the ratio 3 2 + 4 2 \u003d 5 2 is fulfilled for it, i.e. just what the Pythagorean theorem states).

- Homework (music competition)
Teacher. And we have the last competition "Homework" (musical). Each team needs to sing a song and show a skit.
First part of homework.

1 leader.

The fairy tale is not simple, but mathematical

You will now be shown without embellishment.

Maybe there will be something fantastic.

Well, we begin to listen to their story.


One team shows a dramatization of the fairy tale "The Legend of Chess".
The characters are the leader, shah, vizier, sage, accountant.
There is twilight on the stage, the shah lies on the carpet, on the pillows. He's bored. The Shah's guard fans him with fans. From behind the curtain, the voice of the presenter is heard.

Leading. A wise man invented the game we now call "chess". He explained the rules of the game to the shah, and he liked the game very much. Shah decided to generously reward the sage.

Shah. (screams loudly). Vizier! Vizier!

Vizier (runs in and falls to his knees). I hear and obey, my lord.

Shah. Reward the Sage, give him whatever he wants. I am rich enough to be generous.

Vizier (shouting) Call the Wise Man! (Sage appears, looking like an astrologer) What do you want, Sage, for your game?

Sage. Oh Great Shah! I will not ask for gold and jewels. I want one grain to be placed on the first square of the chessboard, two grains on the second, four grains on the third, and so on up to 64 squares, constantly doubling the number of grains of the previous square.

Shah (laughs). Do I look like a beggar? What, I can't give you what you deserve? Ask for something else.

Sage. Oh mighty lord! Don't be angry, but I don't need anything else.

Shah (displeasedly waving his hand). Vizier, give him what he asks.

Leading. Several days have passed. Shah played chess all day and thought about the Wise Man.

Shah. Vizier! Vizier!

Vizier (runs in and falls to his knees). I am here my lord!

Shah. Awarded the Sage?

Vizier. Oh no, Great Shah! All state accountants count grain.

Shah. How could you disobey? Call the accountant here! (Accountant crawls on his knees, bowing incessantly) Why hasn't the sage been rewarded yet?

Accountant. Oh, great and bright sovereign! In your entire state there are not so many grains, on the whole Earth there does not grow such a quantity of grain that the Sage wants to receive.

Shah. How much should he give?

Accountant. Here is the number: 18446744073709551615. If 10 grains weigh one gram, then you must give him 184 billion 467 million 440 thousand 737 tons 95 kilograms and 516 grams of wheat, my lord! If on the whole Earth 2 billion tons are grown per year, then in order to give it all the grain, it needs to be grown for 92 years. But the Earth has never grown 2 billion tons of wheat, oh lord!

Shah. A wise man is always a wise man!

Leading. The Hindu king Sheram (Indian prince Siren) learned to play chess and admired the wit and variety of positions in this game.

18 quintillions 446 quadrillions 744 trillion 073 billion 709 million 551 thousand 615. if the king could sow wheat on the entire surface of the Earth, counting the seas, and oceans, and mountains, and the desert, and the Arctic and Antarctic, and get a satisfactory harvest, then, perhaps in 5 years he could pay off.


Another team shows a staging of the fairy tale "The Man and the Merchant".
The characters are the host, the merchant, the wife, the man.
There is a table on the stage, a samovar, a bench on the table, a merchant's wife and her daughter are sitting at the window, a merchant enters.
Merchant. Listen, wife, I met a stupid man in the market and made a good deal with him.

Wife. What?

Merchant. Every day he will bring me 100,000 rubles, and on the first day I will give him a penny. Do you hear, a penny for 100,000 rubles! In the second - 4 kopecks and so on whole month will wear every day for 100,000 rubles.

Wife. How does this fool get so much money?

Merchant. It's none of our business. One thing I regret is that I signed a contract for only one month. I'm afraid that this eccentric will realize that he is being deceived, and will not bring his money.

There is a knock. The wife looks out the window.

Wife. There someone came.

Merchant (looks out the window) It's him!

A man enters.

Man. Get your money, merchant, and give me a kopeck!

Taking his penny, he leaves.

Merchant. How I was afraid that he would not come. What if he doesn't come tomorrow? Or will he come and take his money?

Wife. Calm down! If he didn’t understand today that he was being deceived, I don’t think he will understand it tomorrow. They say: "If you're a fool, then for a long time."

Merchant. So it is, but it's still scary.

Leading. Every day a man brought 100,000 rubles and took his pennies. At first, the merchant was happy and did not think about how much he was giving to the peasant. On the 24th day he gave 83,000, and on the 25th - 166,000, and on the 27th day - 671,000 rubles.

Merchant. Woe to me, woe! The man was not so stupid. After all, he gave me only 3 million, and received 10 million rubles from me! What a fool I am! Was it possible to make deals in the market!

Leading. See how unexpected results can be when you don't know math. Probably, neither the shah nor the merchant would have found themselves in a hopeless situation if they knew at least a little bit of mathematics.

The second part of the homework.

1 leader.

And stands in a wonderful land

New city with a palace

And in the golden-domed palace

Signs live there together,

The signs guard the towers,

They sing a song together.
The first team performs to the motive of the song "My Bunny".
You are my plus, I am your minus,

Cosine you, - I am your sine,

You are an axiom, I am a theorem,

You are the consequence, and I am the lemma.

Ma-te-ma-ti-ka my ...

Chorus: I don't sleep well at night

I love math so much

I have loved math for a long, long time.

I don't sleep during the day,

I don't sleep at night

I'm learning, learning, learning, learning, learning.

Knowledge is you, I am a cheat sheet,

If you are zero, then I am a stick.

You are the ordinate, then I am the abscissa,

You are a corner, I am a bisector.

Ma-te-ma-ti-ka my ...

Private you, I am a divider,

You are the denominator, I am the numerator.

You are my circle, I am your sector,

You are my module, I am your vector.

Ma-te-ma-ti-ka my ...

The sum is mine, and I am the difference,

Dolny you, and I - multiplicity,

You are the hypotenuse, I am your leg,

Enough terms for you and me.

Ma-te-ma-ti-ka my ...


2 leader.

Beyond the high mountains

Beyond the blue seas

In the thirtieth state

A beautiful country lives

Mathematics.


The second team performs a song to the tune of the song "Communal Apartment".
Oh, my native country

Land of mysteries and wonders!

Where else is happiness

Where else is this progress?

Under one huge roof

More spacious and lighter.

We don't need a separate house,

Together will be more fun.

It's mathematicians, mathematicians flat,

This is mathematicians, mathematicians country.

Rustling sheets in the morning,

The people are gathering

Pythagoras washes his pants

Euler takes the integral,

Gauss extracts the roots,

Newton makes a binomial.

Someone sets axes

Archimedes sits with a number.


By the evening they all can not sleep,

Brig looks at logarithms,

Bradys is fiddling with the table,

Euclid measures the world.

Bezu himself is there without a trace

Divides a complex polynomial.

We don't need a separate house,

Together will be more fun.


1 leader.

And from now on every day

We will definitely be together

glorify math

And honor her.
Both teams sing the anthem for mathematics (to the motive of the song "What do they teach at school?")

Hymn to Mathematics

Solve equations, calculate radicals -

Algebra has an interesting problem!

Extract integrals,

Fraction divide and multiply

Try hard and good luck will come to you! (3 lines 2 times)


Geometry is needed, but it's so complicated!

Now the figure, then the body - you can’t figure it out.

Axioms are needed

Theorems are so important

Learn them - and you will achieve results!
All sciences are good

For the development of the soul.

You all know them yourself, of course,

For the development of the mind, mathematics is needed,

It was, it will be, it is forever.

  1. Final word from the teacher.

Mathematics is a tool with which a person learns and conquers himself the world. To make a discovery in mathematics, one must love it as each of the great mathematicians loved it, as dozens and hundreds of other people loved and love it. Do at least a small part of what each of them did, and the world will forever remain grateful to you. Love math!


Rewarding teams for victory and participation.
