How do you feel about taking a few minutes away from the drab routine and stretching your brain a little? Then choose any interesting logic question from this article and try to find the answer yourself. Just don’t peek into the answers right away - it’s not only dishonest, but also uninteresting!

Mental workout for kids

Many of these mysteries have been well known since Soviet times, but still do not lose their relevance. The answers to them are so simple and obvious that it is almost impossible to guess right away. Are you ready? Then full speed ahead!

1. “Why do you go to the bed when you want to sleep?” The whole “trick” of this question lies precisely in the wording. After all, if you say it out loud, the brain immediately perceives the first two words as one whole. Why? Well, what is this “why”? You can lie down on the bed, cover yourself with a blanket, close your eyes and... And, by the way, the correct answer is “On the floor.”

2. “When can a person be in a room without a head?” Another logic question with an elementary answer. However, to get to the right decision It can be very difficult for a child, because not even every adult can immediately guess what happens when we stick our head out the window.

3. “Can an ostrich call itself a bird?” You may be surprised, but no special knowledge from the field of zoology is needed in order to correctly answer this question, because even the most educated and erudite ostrich will not be able to call itself anything. If only because he doesn’t know how to speak.

4. “Which words have a hundred consonants?” But here the child will undoubtedly become thoughtful. After all, it’s hard to even imagine such a word - as many as 100 consonants, and what if you add vowels? What kind of lexical monster is this? But the correct answer, as always, lies on the surface - “table”, “groan”, “stop”, “stack”, “stop”.

5. “In front of you is a bathtub filled with water. There is a mug and a spoon on the edge. What should I use to quickly remove all the water from the bath?” Do you think this is a mug? Because she's bigger? And here rational person, looking at your torment, will silently come up and pull out the cork.

6. “Three little pigs were walking through the forest. One walked in front of the two, one walked behind them all, and one walked between the two. How did they go? To be honest, even adults often cannot answer such tricky logic questions. In fact, the piglets in this riddle simply follow each other.

7. “The bull plowed the field all day. How many tracks did he ultimately leave on the arable land? In fact, the bull leaves no traces at all, because the plow he pulls behind him erases them.

8. “At 12 o’clock at night there is a torrential downpour. Could it be that after 72 hours there will be warm, sunny weather?” No probability theory will help you here, relax. But knowing how many hours there are in a day will help - there can be no sunny weather. If only because in the indicated 72 hours it will be midnight again.

So, we looked at some interesting logic questions for children. Now let's move on to other, more complex and interesting tasks.

Other logic puzzles

We bring to your attention others interesting questions on logic, which can make not only kids, but also their parents think.

Pun

"On seashore there was a stone on the surface of which a word of 8 letters was scratched. When the rich read this word, they began to cry, the poor, on the contrary, rejoiced, and the couples in love broke up. What was that word? We will not comment on the answer in any way, because everything will become clear by itself. And the word was “Temporarily”.
“Which word contains 3 letters “l” and 3 letters “p”? - “Parallelepiped”.

For math buffs

“How much earth is in a hole 3 meters in diameter and 5 meters deep?” Still trying to calculate and looking for density different types soils? Don't forget that this is a logic question. By the very fact of its existence, the pit is empty, otherwise it would not be a pit.
“How many times can you subtract 6 from 30?” Yes, not to divide, but to take away! Just one, because next time you will subtract 6 not from 30, but from 24.

Life

“Two friends were walking around the city and suddenly stopped and started arguing. One began to assert that “it’s red.” Another objected to him and said that “it’s black.” The first one was not taken aback and asked: “Why is it white in that case?”, to which he heard: “Yes, because it’s green.” What were they talking about?" The correct answer to this riddle is currants.
“Three centuries ago, this procedure was carried out at a distance of 50 meters. Now this distance has been reduced by 10 times, and all thanks to the invention of a Soviet scientist, which you have probably seen more than once. What is this?" Nothing comes to mind? In fact, we are talking about an eye test chart, also known as

American scientists, who came across this picture and the questions for it, considered it to be one of the most effective IQ tests in the history of mankind. Look carefully at the image, and then try to give the correct answer to just 9 questions.

Questions

How many tourists stayed at this camp?
How long ago did they come here: today or a few days ago?
How far is the camp from the nearest populated area?
How did the tourists get here?
What time of day is it now?
Where does the wind blow from: from the south or from the north?
Where did Shura go?
Name the person who was on duty yesterday.
What date is it now and what month?

Right answers

Are you scratching your head? Well, it’s time to show your cards and demonstrate how elementary the answers are to even the most complex logic questions:

Four. To understand this, just look at the list of duty officers (there are four lines on it), as well as the number of plates and spoons on the mat.
Not today, because between the tree and the tent a nimble spider managed to weave a web.
It’s unlikely, because the guys were able to bring a live chicken with them (or it ran into them by chance, which, however, does not change the essence).
On the boat. Near the tree you can see a pair of oars, and since the cars are in Soviet time there wasn't much, this is the most logical answer.
It’s morning, because the shadow falls to the west, and therefore the sun shines from the east.
This logic question really requires some additional knowledge. For example, you need to remember that on the south side of the tree the branches are always longer than on the north. Next you need to look at the fire - it tilts slightly towards the north, which means the wind is blowing from the south.
Shura went to catch butterflies - from behind the bushes you can see a net falling on a winged beauty.
As you can see, Shura went to get butterflies, and the boy sitting next to the backpack with the letter “K” is Kolya. That is, two options are no longer available. Another boy is busy taking photographs surrounding nature. He also cannot be on duty. But what is his name? Taking a closer look, you can see that in the backpack with the letter “B” there is a tripod - an indispensable attribute for a photographer. We conclude that the photographer’s name begins with the same letter - which means Vasya takes photographs. By the method of elimination we find out that Petya is on duty today, and from here we come to the conclusion that Kolya was on duty yesterday.
The answer to this question is closely related to the previous one. So, Petya is on duty today. Next to his name on the board is written the number 8 - the 8th number. As for the month, the very situation in the picture suggests that it takes place in August - only then do watermelons appear in our latitudes. Of course, they are also available in September. But it can be quite difficult to find butterflies at the beginning of autumn, and the first fallen leaves appear on the ground.

Interesting? Did you know that only 6% of people can answer all 9 questions correctly? If you succeeded, congratulations, because this means that your IQ is 130 or more.

Is popular destination in teaching not only children, but also adults. In this case, logic problems become an excellent tool for increasing the existing level.

Features of logical thinking

The main operations of logical thinking are:

analysis is the process of mentally dividing an object or object into parts;
synthesis - establishing relationships between elements to create an overall picture;
abstraction - selection essential features allowing to describe an object or object without details;
comparison - the ability to find common and distinctive features between different objects;
generalization - grouping an object according to a common characteristic;
concretization is an appeal to the details that characterize an object, which makes it possible to reveal its content.

Logical thinking is inextricably linked with other mental functions. Therefore, by developing it, a person simultaneously improves memory, attention, imagination, perception, etc. To successfully solve logic problems, theoretical knowledge and personal experience are required.

Basic ways to develop logical thinking

The tasks that are proposed to be regularly solved for the development of mental activity can be divided into the following groups:

Examples of tasks for ingenuity

This problem is easily solved by preschoolers. Mathematicians and programmers usually complete it within an hour. Others may spend several days without finding an answer.

Solution: The numbers indicate how many circles are in each combination. Accordingly, the last one has one circle, and after the sign there should be a unit.

How can you bring water in a colander? Answers could be: freeze the water, in the form of ice, etc.
Why do people walk? Solution: on the ground.
A star fell from the sky,

The children said: “Hurray”!

That's the main question!

Answer: one.

Two trains started simultaneously from Kazan and Ulyanovsk. The speed of the Kazan one is 3 times higher than the Ulyanovsk one. Which one will be further from Ulyanovsk at the time of their meeting? Answer: both trains will be at the same distance from Ulyanovsk.
Two mothers and two daughters divided three peaches among themselves. How could they do this? Answer: everyone got a peach, because there were three of them: a girl, her mother and grandmother.
In what situation is a person moving at the speed of a racing car? Solution: when he is in it.

Charades

Both children and adults are interested in developing thinking in game form. Poetic forms are often used.

First there will be a two. And next to him is a man,

Unlike many of high rank;

Putting it together, we immediately get

The thing that divides the whole book into parts. (Paragraph).

Let's take a number and put a note next to it,

And we’ll put the letter “r” at the end,

Let's get a man whose job

We see him every day, he’s great! (Carpenter)

There are so many L's in it.

It was as if he wanted to eat them

Wooden and simple

Every home has one.

You can sit down for him

And a delicious piece to eat. (Table)

You buy me in the store,

After all, I am delicious, beautiful and lush,

Tasks to find an extra element

Milk, cottage cheese, sour cream, lard, cheese.
Mechanic, doctor, engineer, butterfly, teacher.
Hate, despise, be irritated, understand, be indignant.
2, 12, 24,46, 62.
Class, lesson, teacher, student. The word “class” is redundant, because it does not begin with the letter “u”.
Cakes, scissors, waffles, candies. The word “candy” will be redundant, because the stress in it does not fall on the first syllable.
Elephant, restaurant, table, chair. The answers may be different words, depending on the classification attribute. For example, restaurant, because it does not start with the letter “s” and because it contains more than one syllable, elephant, because it does not belong to a catering establishment.

Similar problems are often proposed for mastering mathematical material. Most often, rows are built from numbers. Although more complex tasks also require a text version.

Logic problems - These are tasks that are aimed at developing thinking, the ability to think, and grasp the connection between concepts. They teach children to find the relationship between cause and effect and predict the outcome.

Intellectual development of a child preschool age is an important step to prepare for school. Thinking is cognitive process, the approach to which is significantly different in adults and children. An adult has a set of ready-made knowledge, but a child learns everything for the first time, so everything is interesting and entertaining for him. In this unfamiliar world, the child still does not understand everything; he asks many questions, explores on his own, and draws his own conclusions. That is why the development of logical thinking in children plays an important role in preparing for school.

Development of logical thinking through tasks and riddles.

Logical thinking is thinking based on reasoning, combining different areas of knowledge in order to ultimately formulate an answer to the question posed in the problem. All types of logical thinking are closely related to speech. Logic games and tasks have great importance V raising and teaching children. They are interesting to the child, draw him in and make him think.

A problem invented by the learned monk and mathematician from Ireland Alcuin (735–804).
The peasant needs to transport a wolf, a goat and a cabbage across the river. But the boat is such that only a peasant can fit in it, and with him either one wolf, or one goat, or one cabbage. But if you leave a wolf with a goat, then the wolf will eat the goat, and if you leave a goat with cabbage, then the goat will eat the cabbage. How did the peasant transport his cargo?
Solution 1.: It is clear that we have to start with a goat. The peasant, having transported the goat, returns and takes the wolf, which he transports to the other bank, where he leaves it, but he also takes the goat and takes it back to the first bank. Here he leaves her and transports the cabbage to the wolf. Then, returning, he transports the goat, and the crossing ends safely.

Ingenuity tasks for elementary school

Golovina Tatyana Sergeevna, primary school teacher

Dear colleagues, I present to your attention a selection of ingenuity tasks for use in lessons with primary school-age students.

I think that from the very younger age It is necessary to offer children similar tasks. Such tasks are usually very short in wording. To guess them, the child must have a developed outlook and knowledge about the world around him. You need to start teaching with riddles. They teach imaginative, non-standard thinking, which contributes to the development of logic and ingenuity. It is necessary to offer children different puzzles and not rush to explain the answer to them. At school, a collective form of work is suitable for solving such problems - in pairs, in groups. And they will solve the problem “one head is good, but two are better,” and learn to work in a team. Puzzles and charades develop ingenuity well.
