Event progress.
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, 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.
Conducting competitions and games.
- Greeting teams.
1 leader. So that we do not disturb the KVN order,
We are glad to hear your greetings.
Team "Radius" (to the melody of folk ditties)

Teacher. While the jury is counting the points, we have several interesting messages with hints.
2 leader. Who doesn't notice
He doesn't study anything.
Who does not study anything -
He is always whining and bored.
For all.
Question. This theorem is studied in high school and is called the "bride theorem". Formulate it.
Hints:
The theorem is proved in the course of geometry and is considered one of the most important theorems of the course.
The theorem is used at every step in the study of geometric questions.
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.
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.
Particular cases of this theorem were known to some other nations even before its discovery.
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 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! (the 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 understand 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. Take it easy! 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.

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.

Beyond the high mountains
Beyond the blue seas
In the thirtieth state
A beautiful country lives

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.

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.

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

Contest "Experts in physics".
N.V. : task 1.
And now each team will give the answer to the question and write it down on a piece of paper.
A lone physicist, scratching his head,
Measures length, mass and time.
A couple of physicists dream together
Measure temperature, density, volume.
Three physicists, lining up in a row,
Measure energy, speed, charge.
Four physicists in a good mood
Measure pressure, and in bad - acceleration.
Five physicists run out into the square,
Measure impulse, frequency, force and area.
So, question: How many physical quantities named in this poem? collect sheets, pass to the jury.
The teacher calls the correct result. (fifteen)
Task 2.
Here is the black box in front of you,
Think and calculate for yourself.
The ammeter will show you the current
A voltmeter will tell you the voltage.
Everything we need, they fix,
But how are the resistors connected?
There are only two in the box.
And two ohms each.
Contest "Experts in Mathematics"
O.V. :
Task 1.
Archaeologists of the distant future will someday unearth two petrified diaries with a large number of twos. In Misha's diary they will find 234 deuces, and in Tolin 2/3 of the number of these deuces. How many deuces will be found in 2 diaries?
- 234*2/3 = 156 - "2" in Tolin's diary.

Contest "Connoisseurs of logic"
N.V. : Problem with matches.
Match crayfish creeps up, Move 3 matches so that it crawls down.
O.V. : We ask the jury to check the correctness of the assignment
N.V. : And, finally, let's figure out who the captain is, because there is a competition of captains ahead.
O.V.: The captain is the head and senior coach of the team. Before the tournament, he works with the team like an ox, and during the game he fights with the jury like a lion. Captains competition
N.V. Captains, please come to me. You are invited to solve a problem about a turnip.
Answer and answer in writing.
Which of the captains will be ready to answer, raise your hand so that the jury can see that you are the first.
A task. The grandfather, holding the turnip, develops a traction force up to 600 N, the grandmother up to 100 N, the granddaughter up to 50 N, the Bug up to 30 N, the cat up to 10 N and the mouse up to 2 N. What is the resultant of all these forces directed along one straight line and to the same side?
Would this whole company cope with a turnip without a mouse if the forces holding the turnip in the ground are 791 N?
(Answer: The module of the resultant force, equal to the sum of the modules of forces, will be equal to 792 N. The contribution of a muscular mouse to this mighty impulse is 2 N, so things will not work without mouse Newtons!
O.V. : While the captains are solving the problem, there is a competition for the teams Stories with hints
You must guess the word. We give you hints, with each hint you lose one point. Maximum amount points that you can bring to your team's piggy bank 5 points.
