Opening of the "Week of Mathematics"
Dedication to mathematics. Arithmetic! Even in stone Age A person addressed you. Without you it is impossible to count objects, it is impossible to build bridges where something complex and new must be created, Best friend you become. If before you had to be alone a lot difficult questions to decide, Now in the vastness of the big planet You are with us mother of many children. Geometry, algebra are your children, With them we make dreams come true, But remember: huge success You owe yours to the Man.Important knowledge. Nowadays, in order to build and drive a machine, you first need to learn mathematics at school.
Whether in a modern war, or in years of peaceful labor, Mathematics is certainly needed when making calculations.
Without an account there will be no light on the street.
Without counting, a rocket cannot rise.
Without an invoice, the letter will not find the addressee,
And the boys won’t be able to play hide and seek.
Our arithmetic flies above the stars,
Goes to the seas, builds buildings, plows,
Plants trees, forges turbines,
It reaches right up to the sky.
Count, guys, count more precisely:
Feel free to add a good deed,
Get rid of bad things as soon as possible.
The textbook will teach you accurate counting,
Hurry up to work, hurry up to work!

Tuesday Crafts Competition " Interesting numbers
And figures"
Students in a technology lesson make a panel “Interesting Numbers and Shapes.” The basis is taken on a cardboard blank in the form of a geometric figure (circle, oval, rhombus, etc.). Then the children sculpt numbers from plasticine and attach them to a shaped base. The works are bright and unusual.
The work completed in the classroom is used to create an exhibition. At the end of the week, the children choose their favorite panels, and the teacher presents a certificate of “People's Choice Award”
Wednesday Exhibition of drawings “Who makes friends with numbers”
Hello, a new game! Mathematical!
Exhibition of drawings “Who makes friends with numbers” In an art lesson, students draw any number in the form of any object that it resembles. For example, 1 – a person standing sideways, 2 – a swan, a standing snake, 3 – a bird in flight, 4 – an overturned chair, 5 – a unicycle, etc. Hello, new game! Mathematical! Game "Naughty One" Students stand in a semicircle in front of the teacher. The teacher goes around them and quietly places a unit (plastic or paper or other material) into someone’s hands. This man becomes naughty one. When counting: “One, two, three, One, come out!” the one with the number must run out of the row. And, those who stand next to this student must hold him back. The one who kills the one running out first becomes the leader. Game "Find a Pair" One person is number two. In five minutes, the number two should divide some children into pairs so that: Both are fond of the same sport. Both of the couple were the same height. Both had the same hair or eye color. Both had the same color clothes. Both went to the same circle. Both sat on the same row at school, etc. The game is played several times. The winner is the one who manages to collect the most pairs in five minutes. Game "Calling numbers" Students are divided into two teams with the same number of participants. Calculated by numbers. Each team has 1, 2, 3, etc. that stand next to each other. In front of the teams in the middle, 3-4 meters from the first number, there is a pin. The teacher calls out any number, and students with such numbers from one and the other team must run out and take the pin. The team that takes the pin first most often wins. Game "Mathematics from pencils" To play this game you need colored pencils. Two teams compete. Students in teams stand in pairs. In front of each team, at the same distance, there are pencils (10-15 pieces) in a small gift bag. The teacher names the number, figure and others mathematical concepts, and a couple from the team runs to the bag with pencils and lays out the named definition.
For example, a triangle - 6 pencils, a broken open line - 5 pencils, three - 4 pencils, plus - 4 pencils, cm - 7 pencils, x(x) - 4 pencils, pentagon - 7 pencils, 12 - 7 pencils, greater than sign - 4 pencils, 85 – 12 pencils.
Thursday Intellectual marathon

Mathematical tales
"Proud Number One"- Hello rocket! - exclaimed Number One, seeing a sharp-nosed rocket in the sky. I'm Number One like you! You are alone in deserted space and you are not afraid of anything! I love counting those who are alone! The one who is alone is the most important! “I’m not alone, there are astronauts inside me, and stars around me,” the rocket objected. “Number One, let’s go for a walk,” called Unit her neighbor Number Two. - I want to walk alone. “The one who alone is the most important,” Unity answered proudly. – There is one sun shining in the sky and a person has only one head. “But a person walks on two legs and does everything with two hands,” objected Two. “The most important thing in a person is his head,” Unity repeated stubbornly. “But two eyes and two ears,” objected Deuce. - Can the head work well without them? Teacher: Guys, help the numbers decide who is more important: One or Two?
« What does number 2 dream about? One day, Number Two met a swan and told him: “I look like you, and I dream of learning to fly.” “I don’t want to fly anymore,” the swan answered sadly. “My swan fell into a hunter’s snare, and I’m sad without her. “I’ll help you free the swan,” promised Deuce. Soon two beautiful swan bowed to number Two and said: “Thank you for your help, you look like us and are as kind as us.” “But I don’t know how to fly like you,” Deuce sighed. - Take these two white feathers from us as a souvenir, they will fulfill your most cherished wish, - suggested the swan. The next day, Number Two proudly soared in the air on two large wings. “The swans gave me two feathers, but when they flew away, the feathers turned into wings,” Deuce excitedly told the numbers. “Whoever dreams of flying will definitely fly,” the numbers decided. Teacher: guys, what else do you think number Two dreams of?
"Who is number three friends with" Number Three has a cheerful friend, Traffic Light. He stands at the intersection and winks at all cars and pedestrians with three multi-colored lights: red, yellow and green. Number Three likes red best. While it burns, she treats the traffic light with her delicious triangular cookies. Traffic light eats a cookie and tries to guess what it is made of: - Raisins, almonds and rice. “No, I treated you to such cookies yesterday,” Troechka laughs. “Cherry, peanuts and oats,” Traffic Light guesses again. Triangular number three cookies always consist of three products: fruits, nuts and grains. But it is difficult for Svetofor to guess what exactly it consists of. Teacher: What else can you cook from three products?

With the help of numerology, you can calculate not only love, but also friendship. It is always useful to know how best to communicate with a particular friend (girlfriend), which qualities are worth paying attention to, and which ones are better not to pay attention to. Such an approach to friendship makes relationships comfortable and long-lasting, relieves you of the burden of petty grievances and allows you to better understand the person you are letting into your life and soul.
In order to general outline to learn how to behave with this or that person, it is not at all necessary to be professional psychologist or watching this person for many years natural environment. The number of his Name will tell you this after short and not troublesome calculations.
Calculating Friend's Number
If you have already calculated your Number, then you know how to do it. If not, then take the full name of your friend (girlfriend) and convert the letters into numbers, consistent with the table.
1 2 3 4 5 6 7 8 9

Today, as an example, let’s take the name Anastasia Valerievna Bokova.
Anastasia: 1+6+1+1+2+1+1+6=19=1+9=10=1+0=1
Valerievna: 3+1+4+6+9+3+6+3+6+1=42=4+2=6
Bokova: 2+7+3+7+3+1=23=2+3=5
Add further: 1+6+5=12=3
So, the Number of the Name for Anastasia Valerievna Bokova is 3.
If, as a result of the final addition, you get 11 or 22, then further reduce them to prime number no need - these are Master Numbers, and they have their own definitions.
Now look at how best to build relationships with a representative of a particular Number.
If your friend’s Number is 1, then remember that this is a leader person, and you should not fight with him for this very leadership. Give in to him, even condescendingly, try to put up with the fact that he considers himself right in everything. This strong personality, so you will only benefit if you treat your friend Unit with respect and reverence. He will not leave you without help; by force of character he will pull you out of any troubles and out of the blues. And if you need to accept volitional decision, he will push you to this, and he will do it in such a way that you will be sure that you made this decision on your own.
This is a wonderful friend. He is a priori charged with partnership, so he listens to your mood, your opinion, and your desires. Answer him in the same way, and then after many years you will be able to say that closer than a friend you didn't and don't. Just remember that no matter how your friend treats you, no matter how much he gives you his whole soul, he will not tolerate playing with one goal for a long time. So try to fit in. With such a friend you can not only have fun and share problems, but also, if necessary, live under the same roof as family.
A person whose Name Number is 3 tries to express himself in all ways available to him, including at the expense of friends. Therefore, be prepared for the fact that such a friend, without even noticing it, will periodically set you up, involving you in various kinds dubious enterprises. And at the same time, he won’t care how you get out of it. But with such a friend you will never be bored. They will always tell you fascinating story, they’ll be ready for another adventure. Just try to succumb less to the charm of your friend-Troika and think about your interests.
Four as the Number of the Name makes a person a boring and limited friend. Not only will he himself constantly observe all the rules and try not to violate generally accepted commandments, but he will also not give you peaceful life. However, sometimes such people get skidded around corners, and they go into all sorts of troubles. But it’s up to you to clean up the consequences of the spree. Friendship with such a person is not easy; in order to tolerate him next to you for a long time, you need to love this person very much. Although there is a huge advantage in such a friend - he will never leave you in trouble, he will serve you faithfully. The main thing is to be patient.
Friendship with a person who has a history of “A” promises exciting adventures, trips and “away” parties. The main thing is not to try to dampen his enthusiasm, otherwise he will easily leave you sitting in front of the TV and find himself a more suitable company for fun outings. And you shouldn’t expect frankness from such a friend - he will tell you exactly as much as he considers necessary so that he private life remained only his property. Open on the outside and closed on the inside - this is the kind of friend a Five person makes.
Such a friend is characterized by a responsible attitude towards everyone around him. That is, be prepared for the fact that they will look after you, guide you and try to protect you from mistakes. It is difficult to quarrel with such a friend; he is always ready to compromise, but not because he does not have his own opinion, but because he seeks harmony in everything, including in friendly relations. The most harmonious friendship will be with such a person if you are connected with him common cause or a hobby, if you have one with him common interests. But do not try to brush aside the concern of such a friend - if you offend him with ingratitude, it will not be easy to restore the relationship.
Sevens are reluctant and infrequently make close friends; they prefer loneliness. But if things work out with such a person friendly relations, then be prepared for the fact that your every action will be subject to analysis, every secret of yours entrusted to such a friend will be carefully examined, and in the most meticulous way such a friend will try to understand the motives of each of your actions. That is, you will simply become a “guinea pig” for him for his mental exercises. It’s just that such people perceive those around them solely as subjects for experimentation, and if they are friends with someone, it is only because they cannot figure out this person.
Friendship with the Eight will be harmonious if it is built on financial equality and the same mutual assistance. Best of all, a person with a Name Number of 8 understands the language of numbers. There may be some commercialism in the relationship, but if you build with such a friend general business, then you will only gain - both morally and financially. But don’t try to outwit the Eight - he will quickly “count” you, and you will be left with nothing. But any of your problems related to money or payments, your friend will solve for you quickly and with pleasure. For a bottle of cognac or champagne. Well, or for a chocolate bar.
It is easy and pleasant to be friends with a person whose Name Number is 9. On the one side. Without demanding anything in return, he will be devoted to you, will be sincerely interested in your affairs, and will help you even when you don’t ask for it. A friend will serve you as one serves a beloved mistress. But won't such service seem intrusive to you? Relationships with a Nine must be strictly regulated; rare meetings will not allow your friend to interfere unauthorizedly in your life and will make communication mutually pleasant.
A relationship with the owner of Master Number 11 will force you to improve, you will involuntarily fall under the influence of his character, and you will want to correspond to him in everything. Whatever your friend does, you will want to imitate him, follow him, become, if not equal to him, then at least just a step lower. It's tedious at times, but very rewarding. Such a friend will never leave you in a difficult situation; he will find a way out of any situation. difficult situation. And he will be a teacher, a nanny, and a confidant for you.
A friend with Master Number 22 will help you build your life. He thinks big, so it's easier for him to understand your true purpose, understand what you want. It’s worth listening to such a person; he brushes aside emotions, so he sees real picture. If your Name Number is not 22, then do not try to be on an equal footing with it, accept its superiority, and your life will become orderly and prosperous.
Friendship is a mutual process, but each of us strives to get something specific from a friendly relationship. Someone just needs to be listened to and sympathized with, someone is looking for economic gain, and someone needs a like-minded person and ally. And if we want to get what we want, we must take into account the character of the friend. After all, one person will be happy to give you what you expect from him, and another will give it to you once, twice, and then send you to deal with your problems on your own. This is why you use it, because if you give your friends what THEY expect from you, then they will answer you in kind over and over again.

Hello, new game! Mathematical!
Game "Naughty One".
Students stand in a semicircle in front of the teacher. The teacher goes around them and quietly places a unit (plastic or paper, or other material) into the student’s hands. This person becomes a mischievous One. When counting: “One, two, three, One, come out!” the one with the number must run out of the row. And, those who stand next to this student must hold him back. The one who kills the one running out first becomes the leader.
Game "Find a Pair".
One person is number two. In five minutes, the number two should divide the children into pairs so that both are interested in the same sport; both in the pair were of the same height; both had the same hair or eye color; they both had clothes of the same color; both went to the same circle; both sat in the same row at school, etc. The game is played several times. The winner is the one who manages to collect the most pairs in five minutes.
Game "Calling numbers".
Students are divided into two teams with the same number of participants. Calculated by numbers. Each team has 1, 2, 3, etc. that stand next to each other. In front of the teams in the middle, 3-4 meters from the first number, there is a pin. The teacher calls out any number, and students with such numbers from one and the other team must run out and take the pin. The team that takes the pin first most often wins.
Game "Mathematics from pencils".
To play this game you need colored pencils. Two teams compete. Students in teams stand in pairs. In front of each team, at the same distance, there are pencils (10-15 pieces) in a small gift bag.

Once upon a time there were two brothers
Triangle with square.
The eldest is square,
Good-natured, pleasant.
Junior - triangular,
Always dissatisfied.
Square: Why are you angry brother?
He shouts to him:
Triangle:"Look,
You are fuller and wider than me.
I only have three corners
You have four of them!”
But the square answered:
Square:"Brother!
I’m older, I’m a square.”
And he said even more tenderly:
Square: It’s unknown who is needed more!”
But night came and to my brother,
Bumping into tables
The younger one climbs stealthily,
Cut corners for the elder.
As he left, he said.
Triangle:“Have a nice
I wish you dreams!
When I went to bed I was square,
And you’ll wake up without corners!”
But in the morning younger brother
I was not happy about the terrible revenge.
He looked - there was no Square,
I was speechless... I stood there without words...
So much for revenge! Now my brother...
Eight brand new corners!
Mathematical tales.
"Proud number one."
- Hello, rocket! - exclaimed Number One, seeing a sharp-nosed rocket in the sky. I'm Number One like you! You are alone in deserted space and you are not afraid of anything! I love counting those who are alone! The one who is alone is the most important! “I’m not alone, there are astronauts inside me, and stars around me,” the rocket objected. “Number One, let’s go for a walk,” called Unit her neighbor Number Two. - I want to walk alone. The one who is alone is the most important,” Unity answered proudly. - There is one sun shining in the sky and a person has only one head. “But a person walks on two legs and does everything with two hands,” objected Two. “The most important thing in a person is his head,” Unity repeated stubbornly. “But two eyes and two ears,” objected Deuce. - Can the head work well without them? Teacher: Guys, help the numbers decide who is more important: One or Two?
“What does number 2 dream about?”
One day, Number Two met a swan and told him: “I look like you, and I dream of learning to fly.” “I don’t want to fly anymore,” the swan answered sadly. “My swan fell into the hunter’s snare, and I’m sad without her. “I’ll help you free the swan,” promised Deuce. Soon two beautiful swans bowed to the number Two and said: “Thank you for your help, you look like us and are as kind as us.” “But I don’t know how to fly like you,” Deuce sighed. “Take these two white feathers from us as a souvenir, they will fulfill your most cherished wish,” the swan suggested. The next day, Number Two proudly soared in the air on two large wings. “The swans gave me two feathers, but when they flew away, the feathers turned into wings,” Deuce excitedly told the numbers. “Whoever dreams of flying will definitely fly,” the numbers decided.
Teacher: Guys, what else do you think Number Two dreams of?
"Who is number three friends with?"
Number Three has a cheerful friend, Traffic Light. He stands at the intersection and winks at all cars and pedestrians with three multi-colored lights: red, yellow and green. Number Three likes red best. While it burns, she treats the traffic light with her delicious triangular cookies. Traffic light eats a cookie and tries to guess what it is made of: - Raisins, almonds and rice. “No, I treated you to such cookies yesterday,” Troechka laughs. “Cherry, peanuts and oats,” Svetofor guesses again. Triangular number three cookies always consist of three products: fruits, nuts and grains. But it is difficult for Svetofor to guess what exactly it consists of.
Teacher: What else can you cook from three products?

Team presentation. Mathematical relay race.
Examples for 4 teams are written on the board. Each student comes out and writes an answer. The winner is the team that solves faster and more correctly 2+9 48-40 55+5 16-8 70-50 9+8
In the depths of centuries...
The teacher makes a short introduction to this competition. He shows and talks briefly about ancient number systems. After the story he offers a task.
“In ancient times, there was no single accounting system for all countries.
Just some 500 years ago, there was no single account even in enlightened Europe, not to mention some in Africa or America. But, nevertheless, people still wrote down the numbers somehow. Each nation had its own or borrowed from a neighbor system for recording numbers. Some used letters, others - icons, others - squiggles. For some it was more convenient, for others not so much. Later, man learned to use symbols to different units accounts. He would draw a line or other mark for any item he was counting, but he still had no words to indicate the numbers. Even later, man began to count using his fingers.
The counting system we use today was invented in India a thousand years ago. Arab merchants spread it throughout Europe by 900. This system used the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0. These are decimal system, built on the basis of tens. Since we have 10 fingers, this has led to the use of the number 10 in counting systems.
Slavic Cyrillic decimal alphabetical numbering. This numbering was created together with the Slavic alphabetic system for translating sacred bible books for the Slavs by the Greek monks brothers Cyril and Methodius in the 9th century. This form of writing numbers became widespread due to the fact that it was completely similar to the Greek notation of numbers. Until the 17th century, this form of recording numbers was official in the territory modern Russia, Belarus, Ukraine, Bulgaria, Hungary, Serbia and Croatia. Until now, Orthodox church books use this numbering.
Ancient Chinese number system. This system is one of the oldest and most progressive, since it contains the same principles as the modern “Arab” one that we use. This system arose about 4,000 thousand years ago in China. Assignment: you need to translate numbers from ancient Chinese into modern Arabic and find the result. Each team receives a card with written mathematical expressions with ancient Chinese numbers.
Mayan number system. This system is very interesting because its development was not influenced by any of the civilizations of Europe and Asia. This system was used for the calendar and astronomical observations. Characteristic feature hers was the presence of a zero (an image of a shell). The base of this system was the number 20, although traces of the fivefold system are strongly visible. The first 19 numbers were obtained by combining dots (one) and dashes (five).
Exercise:
Roman number system. This is the most known system, after the “Arab”, it arose more than two and a half thousand years ago in Ancient Rome. Numbers in this system, just like ours, were written from left to right, from largest to smallest. Roman numerals have been used for a very long time. Even 200 years ago, in business papers, numbers had to be denoted by Roman numerals (it was believed that ordinary Arabic numerals were easy to counterfeit). We encounter it quite often in Everyday life. These are chapter numbers in books, century indications, numbers on a watch dial, etc.
Exercise: you need to convert numbers from the Mayan number system to modern Arabic and find the result. Each team receives a card with written mathematical expressions with ancient Chinese numbers.
New or Arabic numbering. The counting system we use today was invented in India a thousand years ago. This is the most common numbering today. The name "Arab" is not entirely correct for it, since although it was brought to Europe from Arab countries, but she was not native there either. Arab merchants spread it throughout Europe by 900. This system used the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0. It is a decimal system built on the basis of ten. Since we have 10 fingers, this has led to the use of the number 10 in counting systems. The ancient image of decimal digits is not accidental: each digit represents a number by the number of angles in it. For example, 0 - no corners, 1 - one corner, 2 - two corners, etc. The writing of decimal numbers has undergone significant changes. The form we use was established in the 16th century.
The most attentive.
All teams simultaneously for 3 seconds. a card or presentation slide is shown.
Exercise: find the sum of the numbers. The card (screen) shows the following figures: square, circle and triangle. They contain numbers respectively: 7, 9, 3. Each team is given Blank sheet to answer questions. The answers are then submitted to the jury for verification (correct answer - one point). After viewing, the teacher asks next questions:
What number is written in the square?
- What color is the circle drawn?
- In what figure is the number 9 written?
-Which figure stands last?
Which figure is the largest?
Logical endings.
The teacher formulates the first part of the sentence to each team in turn.
1. If the table is higher than the chair, then the table...
2. If the river is deeper than a stream, then the stream...
3. If 42 >41, then 41...
4. If the sister older than brother, then brother...
5. If right hand right, then left...
6. If Sasha left the house before Seryozha, then...
7. If a tiger is stronger than a wolf, then the wolf...
8. If 1 segment is shorter than 2, then 2 ...
Artists' competition.
1. Draw with both hands at the same time: one a circle and the other a rectangle.
2. At the leader’s command, draw with eyes closed square, oval in the middle, triangle on the right.
Geometric puzzles.
On the screen or on the board, the teacher shows mathematical expressions made up of geometric shapes. Each figure contains numbers hidden: 0, 13, 3, 7. You need to distribute the numbers so that you get true equalities. Note: identical figures -same numbers, different ones have different ones.
Interesting questions for captains.
Competition for team captains. Each captain answers 2 questions. Questions are written on cards, and contestants draw cards one by one and answer them immediately.
1. 16 pears ripened on the pear, and 3 on the willow. How many pears ripened on the willow?
2. If at 11 a.m. it's raining, then is sunny weather possible in 24 hours?
3. Four played dominoes for 20 minutes. How many minutes did each player play?
4. The stick has 2 ends. If one is cut off, how many ends will remain of the stick?
5. What is lighter than 1 kg of iron or 1 kg of cotton wool?
6. The girl has 5 apples. She ate all but 3. How many apples does she have left?
7. There are 4 corners in the room. There is a cat in every corner. Opposite each cat sits 3 cats. How many cats are there in the room?
8. Six potatoes were cooked in a saucepan in 30 minutes. How many minutes did it take to cook one piece?
Number pyramids.
The conditions of this competition are as follows: having examined the first three numbers on the first pyramid, children must understand the principle of forming the third number from the first two and continue recording. The third number is formed by adding the first two numbers, etc., next number is formed by adding the two previous ones.
For example, 3+4 = 7 4+7 =11 7+11 =18 11+18 =29
On the second pyramid, the third number is formed by subtracting 5 from previous date. For example, 87-5 +82 82-5 = 77 77-5 =72 72-5 =67
Numbers in proverbs and sayings.
The teacher gives each team a card with missing numbers in proverbs and sayings. Behind certain time you need to fill in the missing numbers.
1. If you cut down a _______ tree, you plant ten.
2. _________ you can’t clap your hands.
3. The price for a braggart is ________ kopecks.

and figures"
Students in a technology lesson make a panel “Interesting Numbers and Shapes.” The basis is taken on a cardboard blank in the form of a geometric figure (circle, oval, rhombus, etc.). Then the children sculpt numbers from plasticine and attach them to a shaped base. The works are bright and unusual.
The work completed in the classroom is used to create an exhibition. At the end of the week, the children choose their favorite panels, and the teacher presents a certificate of “People's Choice Award”
Wednesday Exhibition of drawings “Who makes friends with numbers”
Hello, new game! Mathematical! Game "Naughty One" Students stand in a semicircle in front of the teacher. The teacher goes around them and quietly places a unit (plastic or paper or other material) into someone’s hands. This person becomes a mischievous One. When counting: “One, two, three, One, come out!” the one with the number must run out of the row. And, those who stand next to this student must hold him back. The one who kills the one running out first becomes the leader. A game "Find a Pair" One person is number two. In five minutes, the number two should divide some children into pairs so that: Both were fond of the same sport. Both of the couple were the same height. Both had the same hair or eye color. They both had the same color clothes. Both went to the same circle. Both sat in the same row at school, etc. The game is played several times. The winner is the one who manages to collect the most pairs in five minutes.A game "Calling numbers" Students are divided into two teams with the same number of participants. Calculated by numbers. Each team has 1, 2, 3, etc. that stand next to each other. In front of the teams in the middle, 3-4 meters from the first number, there is a pin. The teacher calls out any number, and students with such numbers from one and the other team must run out and take the pin. The team that takes the pin first most often wins.A game "Mathematics from Pencils" To play this game you need colored pencils. Two teams compete. Students in teams stand in pairs. In front of each team, at the same distance, there are pencils (10-15 pieces) in a small gift bag. The teacher names a number, figure and other mathematical concepts, and a couple from the team runs to a bag of pencils and lays out the named definition.
For example, a triangle - 6 pencils, a broken open line - 5 pencils, three - 4 pencils, plus - 4 pencils, cm - 7 pencils, x(x) - 4 pencils, pentagon - 7 pencils, 12 - 7 pencils, greater than sign - 4 pencils, 8 – 12 pencils.
Thursday Intellectual marathon
Theater for Young Spectators
Math Marathon
Preparation: colorful cards in the form of geometric shapes with the names of all students - 25 pieces; large letters “Math Marathon”; cards with questions: 15 pieces for round 1, 8 pieces for round 2, 5 pieces for round 3, 3 pieces for round 4, 2 pieces for round 5.
Rules of the game: All students participate in this game. The teacher invites two students, selecting them using name cards, and asks them a question. The one who answered faster and correctly advances to the next round.
For example: there are 25 people in a class, which means that all 25 people participate in the first round, 12 - 13 people go to the second round, 6 - 7 people go to the fourth round, etc. Whoever answered correctly in a pair takes a place for those who continue the competition, and whoever loses fills up the spectator seats.

Theater for Young Spectators
Triangle and Square
Author: Once upon a time there were two brothers
Triangle with square.
The eldest is square,
Good-natured, pleasant.
The youngest is triangular,
Always dissatisfied. Square: Why are you angry brother? He shouts to him:
Triangle: "Look,
You are fuller and wider than me.
I only have three corners
You have four of them!” "Brother!
I'm older, I - square". It’s unknown who is needed more!” But night came and to my brother,
Bumping into tables
The younger one climbs stealthily,
Cut corners for the elder.
As he left, he said. Triangle:“Have a nice
I wish you dreams!
When I went to bed I was square,
And you’ll wake up without corners!” But in the morning younger brother
I was not happy about the terrible revenge.
He looked - there was no Square,
I was speechless... I stood there without words...
So much for revenge! Now my brother...
Eight brand new corners!
Mathematical tales
"Proud number 1"
-
Hello rocket! - exclaimed Number One, seeing a sharp-nosed rocket in the sky. I'm Number One like you! You are alone in deserted space and you are not afraid of anything! I love counting those who are alone! The one who is alone is the most important! “I’m not alone, there are astronauts inside me, and stars around me,” the rocket objected. “Number One, let’s go for a walk,” called Unit her neighbor Number Two. - I want to walk alone. “The one who alone is the most important,” Unity answered proudly. – There is one sun shining in the sky and a person has only one head. “But a person walks on two legs and does everything with two hands,” objected Two. “The most important thing in a person is his head,” Unity repeated stubbornly. “But two eyes and two ears,” objected Deuce. - Can the head work well without them?Guys, help the numbers decide who is more important: One or Two?
« What does number 2 dream about? One day, Number Two met a swan and told him: “I look like you, and I dream of learning to fly.” “I don’t want to fly anymore,” the swan answered sadly. “My swan fell into a hunter’s snare, and I’m sad without her. “I’ll help you free the swan,” promised Deuce. Soon two beautiful swans bowed to the number Two and said: “Thank you for your help, you look like us and are as kind as us.” “But I don’t know how to fly like you,” Deuce sighed. “Take these two white feathers from us as a souvenir, they will fulfill your most cherished wish,” the swan suggested. The next day, Number Two proudly soared in the air on two large wings. “The swans gave me two feathers, but when they flew away, the feathers turned into wings,” Deuce excitedly told the numbers. “Whoever dreams of flying will definitely fly,” the numbers decided.
"Who is number 3 friends with" Number Three has a cheerful friend, Traffic Light. He stands at the intersection and winks at all cars and pedestrians with three multi-colored lights: red, yellow and green. Number Three likes red best. While it burns, she treats the traffic light with her delicious triangular cookies. Traffic light eats a cookie and tries to guess what it is made of: - Raisins, almonds and rice. “No, I treated you to such cookies yesterday,” Troechka laughs. “Cherry, peanuts and oats,” Traffic Light guesses again. Triangular number three cookies always consist of three products: fruits, nuts and grains. But it is difficult for Svetofor to guess what exactly it consists of. HWhat else can be prepared from three products?

Slide 2
Mathematical relay race.
Examples for 4 teams are written on the board. Each student comes out and writes an answer. The winner is the team that solves faster and more correctly 2+9 48-40 55+5 16-8 70-50 9+8In the depths of centuries...
The teacher makes a short introduction to this competition. He shows and talks briefly about ancient number systems. After the story he offers a task.In ancient times, there was no single accounting system for all countries.
Just some five hundred years ago there was no single account even in enlightened Europe, not to mention any Africa or America.But, nevertheless, people still wrote down the numbers somehow. Each nation had its own or borrowed from a neighbor system for recording numbers. Some used letters, others - icons, others - squiggles. Some found it more convenient, others not so much.
Later, man learned to use symbols for different units of counting. He would draw a line or other mark for any item he was counting, but he still had no words to indicate the numbers. Even later, man began to count using his fingers.
The counting system we use today was invented in India a thousand years ago. Arab merchants spread it throughout Europe by 900. This system used the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0. It is a decimal system built on the basis of ten.Since we have 10 fingers, this has led to the use of the number 10 in counting systems.Slavic Cyrillic decimal alphabetical numbering.
Slide 3
This numbering was created together with the Slavic alphabetic system to translate the sacred biblical books for the Slavs by the Greek monks brothers Cyril and Methodius in the 9th century. This form of writing numbers became widespread due to the fact that it was completely similar to the Greek notation of numbers. Until the 17th century, this form of recording numbers was official in the territory of modern Russia, Belarus, Ukraine, Bulgaria, Hungary, Serbia and Croatia. Until now, Orthodox church books use this numbering. Ancient Chinese number system.
Slide 4
This system is one of the oldest and most progressive, since it contains the same principles as the modern “Arab” one that we use. This system arose about 4,000 thousand years ago in China. Assignment: you need to translate numbers from ancient Chinese into modern Arabic and find the result. Each team receives a card with written mathematical expressions with ancient Chinese numbers.Mayan number system
.
Slide 5
This system is very interesting because its development was not influenced by any of the civilizations of Europe and Asia. This system was used for the calendar and astronomical observations. Its characteristic feature was the presence of a zero (an image of a shell). The base of this system was the number 20, although traces of the fivefold system are strongly visible. The first 19 numbers were obtained by combining dots (one) and dashes (five). Assignment: you need to convert numbers from the Mayan number system to modern Arabic and find the result. Each team receives a card with written mathematical expressions with ancient Chinese numbers.Roman number system.
Slide 6
This is the most famous system, after the “Arab” one, it originated more than two and a half thousand years ago in Ancient Rome. Numbers in this system, just like ours, were written from left to right, from largest to smallest. Roman numerals have been used for a very long time. Even 200 years ago, in business papers, numbers had to be denoted by Roman numerals (it was believed that ordinary Arabic numerals were easy to counterfeit). We encounter it quite often in everyday life. These are chapter numbers in books, an indication of the century, numbers on a watch dial, etc. Assignment: you need to convert numbers from the Mayan number system to modern Arabic and find the result. Each team receives a card with written mathematical expressions with ancient Chinese numbers.New or Arabic numbering.
Slide 7
The counting system we use today was invented in India a thousand years ago.This is the most common numbering today. The name “Arab” is not entirely correct for it, since although it was brought to Europe from Arab countries, it was not native there either.Arab merchants spread it throughout Europe by 900. This system used the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0. It is a decimal system built on the basis of ten.Since we have 10 fingers, this led to the use of the number 10 in counting systems.
The ancient image of decimal digits is not accidental: each digit represents a number by the number of angles in it. For example, 0 - no corners, 1 - one corner, 2 - two corners, etc. The writing of decimal numbers has undergone significant changes. The form we use was established in the 16th century.The most attentive.
Slide 8
All teams simultaneously for 3 seconds. a card or presentation slide is shown. Task: find the sum of numbers. The card (screen) shows the following figures: square, circle and triangle. They contain the corresponding numbers: 7, 9, 3. Each team is given a blank sheet to answer questions. Then the answers are handed over to the jury members for verification (correct answer - one point). After viewing, the teacher asks the following questions: - What number is written in the square?
- What color is the circle drawn?
- In what figure is the number 9 written?
-Which figure stands last? -Which figure is the largest?
Logical endings
The teacher formulates the first part of the sentence to each team in turn. 1. If the table is higher than the chair, then the table...2. If the river is deeper than a stream, then the stream...3. If 42 >41, then 41...4. If a sister is older than a brother, then the brother...5. If the right hand is on the right, then the left.. 6. If Sasha left the house before Seryozha, then... 7. If the tiger is stronger than the wolf, then the wolf.. 8. If 1 segment is shorter than 2, then 2...Artists' competition.
1. Draw with both hands at the same time: one a circle and the other a rectangle. 2. At the leader’s command, draw a square with your eyes closed, an oval in the middle, and a triangle on the right.Geometric puzzles
.
Slide 9
On the screen or on the board, the teacher shows mathematical expressions made up of geometric shapes. There are numbers hidden in each figure: 0, 13, 3, 7. You need to distribute the numbers so that the correct equalities are obtained. Note: identical figures have the same numbers, different figures have different numbers.Interesting questions for captains.
Competition for team captains. Each captain answers 2 questions. Questions are written on cards, and contestants draw cards one by one and answer them immediately. 1. 16 pears ripened on the pear, and 3. how many pears ripened on the willow?
2. If it rains at 11 o’clock at night, is sunny weather possible 24 hours later? 3. Four played dominoes for 20 minutes. How many minutes did each player play? 4. The stick has 2 ends. If one is cut off, how many ends will remain of the stick? 5. What is lighter than 1 kg of iron or 1 kg of cotton wool? 6. The girl has 5 apples. She ate all but 3. How many apples does she have left? 7. There are 4 corners in the room. There is a cat in every corner. Opposite each cat sits 3 cats. How many cats are there in the room? 8. Six potatoes were cooked in a saucepan in 30 minutes. How many minutes did it take to cook one piece?Number pyramids.
Slide 10
The conditions of this competition are as follows: having examined the first three numbers on the first pyramid, children must understand the principle of forming the third number from the first two and continue recording. The third number is formed by adding the first two numbers, etc., the next number is formed by adding the previous two.
For example, 3+4 = 7 4+7 =11 7+11 =18 11+18 =29 On the second pyramid, the third number is formed by subtracting 5 from the previous number. For example, 87-5 +82 82-5 = 77 77-5 =72 72-5 =67 Numbers in proverbs and sayings.
The teacher gives each team a card with missing numbers in proverbs and sayings. Within a certain time you need to insert the missing numbers. 1. If you cut down a _______ tree, plant ten.
2. _________ you can’t clap your hands. 3. The price for a braggart is ________ kopecks.4. Without _________ corners, the hut cannot be cut. 5. The horse has ___________ legs, and even then it stumbles. 6. Don’t have ________rubles, but have ______friends.Ode to mathematics.
In 2 minutes, all team members must come up with adjectives praising mathematics, continuing the line Oh, mathematics, you... (entertaining, interesting, serious, developing ingenuity, beautiful, training the mind, necessary, difficult, fun, exciting, important, useful , helping people, etc.) Then, one by one, the teams name the written words and, the team that named the last word, is considered the winner of this competition.
