Logical questions for a child of 6 years. Children's tasks-jokes

Development of attention and ingenuity contribute joke tasks, puzzlescaution the child against hasty and unreasonable conclusions. They should not be solved as usual tasks using one or another arithmetic operation. These tasks should encourage children to reason, think, find the answer, using the existing knowledge.

By teaching the child to listen carefully to the condition of the problem, it is possible to propose a joke problem in which there are numerical data, but no arithmetic should be performed.

It’s not always easy for a child to find the answer, realizing that task with a "secret."  Let the adult be pleased only by the fact that the child will not rush to answer, but try to think, reason, give various arguments and disprove himself. Help him to find the right way of reasoning.

Using joke tasks  and intelligence tasks  can diversify and revitalize activities with children. In addition, tasks of this kind can be used during ma-thematic leisure, fun meetings of pre-school experts, KVNov. To conduct one lesson with children, you can take one or two tasks, and in mathematics leisure you should include no more than five or six tasks of varying complexity. Application mathematical material  outside classes with the whole group of children it is advisable when children are prepared from this point of view.

Tasks for ingenuity for elementary school

Golovina Tatyana Sergeevna, primary school teacher

Dear colleagues, I offer you a selection of tasks for ingenuity for use in class with pupils of primary school age.

I believe that from a very young age it is necessary to offer children similar tasks. Such tasks are usually very short in formulation. In order to guess them, the child must have a developed outlook, knowledge of the surrounding world. You need to start teaching with riddles. They teach the imaginative thinking outside the box that promotes the development of logic and ingenuity. It is necessary to offer children different puzzles and not be in a hurry to explain the answer to them. At school, the collective form of work is suitable for solving such problems - in pairs, in groups. And the puzzle will solve “one head is good, and two is better,” and learn how to work in a team. Well develop ingenuity rebuses, charades.

Interesting tasks for children and their parents

This material may be of interest to teachers of preparatory groups, primary school teachers, parents who are engaged in the formation of non-standard thinking in children. Tasks are available for children of preschool age, interesting for schoolchildren and even adults.
  Tatyana Pochayeva Anatolyevna, pedagogical psychologist of MBDOU "Kindergarten No. 2", Konakovo

Purpose:  development of child's abilities
Tasks:
  - to interest the child in solving non-standard tasks;
  - develop figurative and logical thinking;
  - to offer material for leisure activities in the family.

Working with children, I always tried to develop creative thinking outside the box in them. For this purpose, tasks that can be solved are not enough to be able to add or subtract numbers or to be able to count to one hundred. Finding such tricky puzzles is half the battle, making children interested in solving them is more difficult. It is difficult because the classes are time-regulated very tightly, they are not designed to solve non-standard tasks. I still manage to do something, but I always want more.

In the last school year, at the parents' meeting in the preparatory group, I proposed an option: at the end of the week, each child will receive an envelope with a task. This task needs to be solved within a week and in an envelope send me an answer. The point is voluntary, you want to participate - do not want your will. Of course, they wanted everything, but after two months, those who wanted to diminished, because often the parents (!) Themselves did not understand how to solve this or that problem. And it is very bitter. Only one girl reached the finish, which was quite predictable.

So, the simplest task that I offered to the children in the classroom was: “How to divide the 3 apples lying in the basket between the three girls so that each girl gets 1 apple and one apple left in the basket?” The children immediately begin to offer 2 apples cut, but it does not meet the condition of the problem, which states that each girl should get a whole apple. Then I pick up a basket with 3 apples and ask some of the children to fulfill the condition of the task - to divide the apples. At this moment, there is an insight - we pick up one apple with the basket!

1. Misha returned from fishing pleased.
  - How many fish caught? - asked his comrades.
  - I will not say. But he ate both of them.
  How many fish did Misha catch?
  This is a very easy task, but when the child does not hear the usual numbers, he does not first understand how to solve it.

2. Marina had 7 sweets. She gave 2 candies to her sister Kate, who also had candies. After that, the chocolates of the sisters became equal. Think how many candies did Katya have at first?
  It is also one of the simple tasks, but 2-3 people can solve it immediately in class, the rest do not have time to figure it out.

3. How many squares should I take to glue the cube, sticking 1 square on each side?

4. 3 people waited for the train for 3 hours. How much time did everyone wait?

5. Three fishermen eat three fish in three days. How many days will five fishermen eat five fish?
Decision:   If 3 fishermen eat 3 fish in 3 days, then 1 fisherman eats 1 fish in 3 days. Therefore, 5 fishermen will eat 5 fish in the same 3 days, and not 5, as children and adults often answer.

6. 2 hens in 2 days laid down 2 eggs. How many eggs will be laid 4 hens in 4 days.
Decision:   2 hens in 2 days carry 2 eggs, therefore, 1 hen in 2 days can carry 1 egg. In 4 days, 1 chicken will lay 2 eggs, and 4 hens will lay 8 eggs in 4 days.
  Answer: 8 eggs.

7. One Winnie the Pooh eats for 1 hour 1 jar of honey. How many Winnie the Poohs in 5 hours will eat 5 cans of honey?
Decision:   for 1 hour Vini eats 1 jar of honey, therefore, in 2 hours he will eat 2 cans, for 3 - 3 cans, etc.
  Answer: one Winnie the Pooh will eat 5 cans of honey in 5 hours.

8. Vanya lives in a 12-story building, on the 9th floor, if you count from above. What floor does Vanya live on?
  Decision: If you propose to solve this problem for a preschooler, then it is best to ask him to draw a 12-story house and count the floors in the reverse order. If the child is already in school, the solution is available in his mind without relying on the drawing. It turns out, if you count from the bottom up, after the 9th floor upwards there will be three more floors: the tenth, eleventh, twelfth. If we count from the top down, then all the same after the ninth floor, on which Vanya lives, there will be three more: the third, the second, the first. Therefore, Vanya lives on the 4th floor.

9. Zabyvalka and Putalka bought several pairs of boots at a shoe store, and the total number of boots turned out to be a single number. When the gnomes returned home, Putalka began to make purchases. He did it so cunningly that at the end of the division he had 8 more boots than his friend. How many boots did the surprised Zabvalka get?

Decision: to solve this problem, the child must know what the words "pair" and "single digit" mean. Dwarfs could not buy 10 boots, because the number 10 is a two-digit one. They could not buy 9 boots, because shoes are always sold in pairs. If they bought 8 boots, then all these boots went to Puntka, and Zabyalka did not get anything.

10. Gilt weighs 2 kg and still half a pig. How much does piggy weigh?
Decision:   The gilt weighs 2 kg and still half a pig. We understand that the weight of the two halves is equal to the weight of the mumps; if one half weighs 2 kg, then the whole mumps is 4 kg.

11. The elevator rises to the third floor in 6 seconds. How many seconds will he go up to the fifth floor?
Decision:   in 6 seconds the elevator overcomes two flights - from the first to the second floor and from the second to the third. Therefore, one flight of the elevator passes in 3 seconds. To get to the fifth floor, you need to drive 4 flights. It will take 12 seconds.

12. Adler goes to the cage with a tiger. Every time he takes 2 steps forward, the tiger roars and the dwarf retreats 1 step back. How long does it take to reach the cage, if it is 7 steps away, and 1 step Does the Traveler do in 1 second?
Decision:   to solve this problem, use a picture from which it will be clear that moving 2 steps forward and 1 step back, the Traveler spends 3 seconds to get one step closer to a cage with a tiger. But having come closer to 5 steps in 15 seconds, he takes the last steps in 2 seconds and turns out to be in a cell.
  Answer: In 17 seconds, the Traveler will reach the cage.

13. Once upon a time there was a Serpent Gorynych. He was very picky about food. His right head did not like fruit and could not tolerate cutlets. His left head could not bear pears. Pears, ice cream and cutlets were served for lunch. What will each head of Gorynych choose for lunch?
Decision:   the right head will choose ice cream, the left - cutlets, medium, as the most picky, head will get pears.

14. In two wallets there are 4 coins, and in one purse there are twice as many coins as in the other. How is this possible?
Decision:   To make this happen, we put two coins in each wallet, and then we put one into the other. It turns out that it now has 4 coins, which is 2 times more than in another wallet.

15. A small military unit approached the river. The bridge is broken, and the river is deep. How to be? Suddenly, the officer noticed two boys playing in a boat by the river. The boat is so small that only one soldier or two boys can cross it - no more! However, all the soldiers crossed the river on this particular boat. How did they manage to do this?
Decision:   first both boys are transported in the boat. One of them remains on the other bank, and the second boy returns and gives the boat to one of the soldiers. He crosses the river. The boy, waiting for him on the shore, takes the boat and swims to the rest. Then the cycle repeats until all the soldiers cross.

Good day, dear friends! Do you remember what grades you studied at school? I remember. I have no triples in my certificate. But during any school year there were triples, twos, and even colas sometimes happened. So I think, in whom is Alexandra, my daughter, such? A student on the board of honor hangs! Apparently, those additional exercises that we do with it are bearing fruit.

Lesson plan:

Exercise 1. We connect the incompatible

Very interesting exercise! Useful not only for children, but also for adults. This exercise is used as a test at castings of radio presenters. Imagine, you come to the casting, and they tell you: “Come on, friend, connect us a chicken with a pillar”. In all seriousness, they say so!

The point is precisely in this, you need to connect two completely unrelated concepts. Radio presenters need this so that during live broadcasts you can quickly and beautifully create liner songs for easy transitions from one topic to another.

Well, the kids are suitable for the development of creative, creative, fast thinking.

So how do you connect a chicken with a pillar? There are many options:

1. A chicken walks around a pillar.
2. The chicken was blind, walked and crashed into a pole.
3. The chicken was strong, hit the pole, and he fell.
4. The pillar fell right on the chicken.

Want to practice? Good. Connect:

• chamomile with milk;
• headphones with jellyfish;
• boots with the moon.

Exercise 2. Wordbreakers

If in the previous exercise we connected, then in this we will break, one long word into many short, consisting of letters of a big word. According to the rules, if a letter occurs in a long word 1 time, then it cannot be repeated in short words twice.

For example, the word "switch" is divided into:

• tulle;
• key;
• beak.

I no longer see the options, and you?

You can break any long words, for example, “holiday”, “picture”, “towel”, “polar explorer”.

Exercise 3. Rebus

Solving puzzles helps to think outside the box, creatively. Teaches a child to analyze.

The rebuses may contain images, letters, numbers, commas, fractions placed in a very different order. Let's try together to solve a few simple rebuses.

1. At first, we see the syllable “BA” and “barrel”. Connect: BA + Barrel = Butterfly.
2. The second principle is the same: Baran + KA = Bagel.
3. The third is more complicated. Drawn cancer, and next to "a = y." So in the word cancer, the letter "a" must be replaced by the letter "y", we get "hands". To this we add one more “a”: hands + a = hand.
4. The fourth rebus with a comma. Since the first is the letter "A", the word-otgadka it begins. Then we see the "fist", after the picture is a comma, it means that the last letter should be taken away from the word "fist". We get the "Kula". Now we combine everything together: A + kula = shark.
5. The fifth rebus is difficult at first sight. It is necessary to remove the letter “and” from the word “saw”, and read the word “cat” backwards. As a result, we obtain: plat + current = scarf.
6. The sixth, fully alphabetic rebus. With the first and last letters, everything is clear, but what about the middle? We see the letter "o", drawn in the beech "t", so let's say "in t o". We connect: A + VTO + P = AUTHOR.

Have you trained? Now try solving the rebus yourself.

Your answer choices can be shared in the comments. You will find many different rebuses in children's magazines and.

Exercise 4. Anagrams

Is it possible to turn an orange into a spaniel and vice versa? "Easy!" - Anagram lovers will answer. Even a magic wand is not needed.

Anagram is a literary device that consists in rearranging the letters or sounds of a certain word (or phrases), which results in another word or phrases.

It is also easy to sleep turns into a nose, a cat into a current, and a linden into a saw.

Well, let's try? Let's make it so that:

• "Carriage" flew to the stars;
• The “word” has grown on the head;
• "Lace" learned to fly;
• The atlas became edible;
• "Pump" settled in the forest;
• "Mote" became transparent;
• "Roller" put on the table before dinner;
• "Bun" learned to swim;
• “Daisy” was spinning around the lantern on summer evenings;
• "Park" could not live without water.

Exercise 5. Logical problems

The more logical puzzles you solve, the stronger your thinking becomes. It is not for nothing that they say that mathematics is gymnastics for the mind. Indeed, when solving some of them, you directly feel how the brain moves.

Let's start with those that are simpler:

1. Kohl and Vasya solved puzzles. One boy decided at the blackboard, and the other at the desk. Where did Vasya solve the puzzles, if Kolya didn't solve at the blackboard?
2. Three old grandmothers live in the same staircase, on the third, fifth and seventh floors. Who lives on what floor, if Grandma Nina, lives above Grandma Vali, and Grandma Galya, below Grandma Vali?
3. Yura, Igor, Pasha and Artem came to the finish line in the top four in the race. Who took what place? It is known that Yura ran not the first and not the fourth, Igor ran after the winner, and Pasha was not the last.

And the following three tasks Sashulya brought with the mathematical Olympiad. These are tasks for the third grade.

“A gardener planted 8 seedlings. Of all but four, pear trees have grown. On all pear trees except two pears grow. Pears from all fruit-bearing pear trees, except for one, are tasteless. How many pear trees are pears? ”

“Vasya, Petya, Vanya wear ties only in one color: green, yellow and blue. Vasya said: “Petya does not like yellow color”. Peter said: "Vanya wears a blue tie." Vanya said: "You are both deceiving." Who prefers what color if Vanya never lies? ”

And now attention! The challenge of increased complexity! "Backfilling", as they say. I could not solve it. Long tormented, and then peered into the answers. She, too, with the Olympics.

“The traveler must cross the desert. The transition lasts six days. The traveler and the porter who will accompany him can take with them a supply of water and food for one person for four days each. How many porters will a traveler need to fulfill his plan? Specify the smallest number ".

If on any puzzles you fall asleep, please contact, I will help)

Exercise 6. Matchstick puzzles

Matches for children is not a toy! A means to train thinking. For security reasons, I suggest replacing matches with counting sticks.

These simple little sticks make very difficult puzzles.

To begin with, we shall:

• fold two identical triangles from five sticks;
• from seven sticks two identical squares;
• remove three sticks to make three identical squares (see picture below).

Now more difficult:

Move the three sticks so that the arrow flies in the opposite direction.

The fish also needs to be turned to the other side, shifting only three sticks.

After placing only three sticks, remove the strawberry from the glass.

Remove two sticks to make two equilateral triangles.

Answers can be peeped at the end of the article.

Exercise 7. Truth and lie

Now let's work on Sherlock Holmes! We will seek truth and discover falsehood.

Show the child two pictures, on one of which draw a square and a triangle, and on the other a circle and a polygon.

And now offer cards with the following sayings:

• some figures on the card are triangles;
• there are no triangles on the card;
• there are circles on the card;
• some figures on the card are squares;
• all the figures on the card are triangles;
• there are no polygons on the card;
• there is not a single rectangle on the card.

The task is to determine whether these statements are false or true for each picture with figures.

This exercise can be performed not only with geometric shapes, but also with images of animals. For example, put a cat, a fox and a squirrel in the picture.

Sayings may be as follows:

• all these animals are predators;
• in the picture there are pets;
• all animals in the picture can climb trees;
• all animals have fur.

Pictures and statements to them can be selected independently.

Exercise 8. Instruction

We are surrounded by a variety of subjects. We use them. Sometimes the instructions that are attached to these items, we do not pay any attention. And it also happens that there are simply no instructions for some very necessary subjects. Let's fix this misunderstanding! Write the instructions yourself.

Take, for example, a comb. Yes, yes, the usual comb! That's what happened with Alexandra.

So, instructions for using the comb.

1. The hairbrush is a device for making hair smooth and silky, made of plastic.
2. Use a comb should be with increased shaggy and curly.
3. In order to start combing go to the comb, gently take it in your hand.
4. Stand in front of the mirror, smile, bring the comb to the roots of the hair.
5. Now slowly lead the comb down to the ends of the hair.
6. If on the way of the comb there are obstacles in the form of nodules, then swipe the comb with it several times with weak pressure, while you can cry out a little.
7. Each hair strand should be treated with a comb.
8. Combing can be considered complete when the comb on the way does not meet a single knot.
9. After the combing is completed, it is necessary to rinse the comb with water, put it in a special place for it.
10. If the comb has broken off the clove, you need to throw it in the trash.
11. If the comb has broken off all the teeth, send it behind the tooth.

Try to write instructions for the pan, or slippers, or glasses case. It will be interesting!

Exercise 9. We make up the story

Stories can be made in different ways, for example, by a picture or on a given topic. This, by the way, will help. And I suggest you try to make a story based on the words that must be present in this story.

As always an example.

The words are given: Olga Nikolaevna, poodle, glitter, turnip, salary, gray hair, castle, flood, maple, song.

That's what happened with Sasha.

Olga Nikolaevna walked down the street. On a leash she led her poodle Artemon, the poodle was all brilliant. Yesterday he broke the lock on the locker, got to the box with sparkles and poured them on himself. And Artemon gnawed the pipe in the bathroom and made a real flood. When Olga Nikolaevna came home from work and saw it all, gray hair appeared in her hair. And now they were going for a turnip, because turnips soothe the nerves. And turnip was expensive, cost half a salary. Before entering the store, Olga Nikolaevna tied a poodle to a maple and, singing a song, went inside.

Now try it yourself! Here are three sets of words:

1. Doctor, traffic light, headphones, lamp, mouse, journal, frame, exam, janitor, clip.
2. First grader, summer, hare, button, gap, bonfire, velcro, beach, plane, hand.
3. Konstantin, jump, samovar, mirror, speed, sadness, tripping, ball, list, theater.

Exercise 10. restore order

We already worked as detectives. Now I propose to work as police officers. The fact is that the words in famous proverbs and sayings violated order. We will fight against violators of order. Try to arrange the words as they should be.

1. Food, time comes, in, appetite.
2. Pull out, not, labor, from, fish, pond, without.
3. Measure, time, and, time, seven, cut, one.
4. And, ride, sleigh, love, carry, love.
5. Waiting, not, seven, one.
6. A word, a cat, and, nice, kind.
7. One hundred, and, rubles, have, not, have friends, one hundred.
8. Falls, not, apple, far, apple, from.
9. Flowing, stone, not, water, speed, under.
10. Autumn, according to chickens.

I want to clarify. We do not do this on purpose. That is, there is no such thing as I say: “Come on, Alexandra, sit down at the table, we will develop our thinking!” No. All this between times, if we go somewhere, we go, before going to bed instead of books. It is very interesting to be engaged, so it is not necessary to force anyone.

Well, now the promised answers to matchstick puzzles!

Puzzle answers

About two triangles of five matches.

About two squares of seven.

We get three squares.

Unfold the arrow (watch the color of the sticks).

Turn the fish.

And about two equilateral triangles.
