You can talk a lot about the development of the child, about the benefits of various exercises, techniques. But do not forget that you need to not only read useful books and articles on the Internet, you need to put all this into practice. It is not as difficult and does not take as much time as it seems.

For example, good old (or new unusual) riddles! After all, this is still the method of our grandmothers and great-grandmothers! So you can entertain the child, while doing anything around the house! Older children can even read and solve riddles on their own, on their own or with friends, instead of spending an extra hour on social networks or playing endless shooting games. Riddles for children 10 years old are somewhat more complicated, more interesting than for kids, so do not be afraid that children will be bored guessing them.

Recently, more and more parents are trying to develop their baby from an early age, since everyone already knows about the faster assimilation of information and learning abilities at this particular age.

But when the baby grows up, often the enthusiasm of the parents disappears. And all the successes that have been achieved are gradually fading away.

And absolutely in vain! If the child continues to be interested, to maintain interest in development, in creativity, to notice his natural talents and develop them in every possible way, then in the future the parents will most likely have no problems - how to entertain the child? Or what to do with a child who is bored? And this, in fact, is a big problem of our time - children have forgotten how to play even with expensive “fancy” toys, which they usually now have in abundance, have forgotten how to play with friends in the yard, they have little company - they need a “mass entertainer”, an animator . And parents sincerely believe that this is how it should be - that we and our children simply grew up at different times. But pay attention: you probably have a familiar family where the boy is passionate about sports, rides a bike all the time, plays football, in the summer he not only disappears in the river and climbs trees, but also puts up ads to earn extra money for a cool skateboard ...

And the girls are not all busy posting their next selfie on social networks, many have time to engage in origami, which is now fashionable, go in for music and gymnastics, dance and sports, draw and go to theater studios.

And if you don’t dismiss children as if they were an annoying fly, always pretending to be busy and referring to fatigue (you must admit, we often do this), but make some efforts and show interest, then you can improve the life and life of a small person in such a way that He will be interested and you will not be a burden!

What are the riddles, you ask?

Yes, despite the fact that this is one of those activities that helps the child develop a “thinker”, think outside the box, show logic, recklessly look for a solution. It teaches to think, to master different topics.

Funny, interesting unusual riddles for children of 10 years old form a sense of humor, help to become active and inquisitive.

So go ahead: find, read riddles to children, slip children instead of primitive comics, assign prizes, let them compose their own riddles! In general, create together, and have fun!

Riddle 6

You have a 7 minute hourglass and an 11 minute hourglass. How do you boil an egg in exactly 15 minutes?

Answer 6:

To boil an egg in exactly 15 minutes, you need to do the following:

· Turn over all the hourglasses when you start to boil the egg.

· After the 7-minute clock runs out, you need to start it again.

· After 4 minutes, when the time on the 11-minute hourglass runs out, you need to turn the 7-minute hourglass over again.

· Wait until the 7-minute hourglass runs out, which will take 4 minutes to boil an egg in 15 minutes.

Riddle 7

You are walking down the road and come across a fork in the road. One path leads to certain death, and the other to eternal happiness, but you do not know which one.

One brother tells the truth all the time and the other lies all the time. You can only ask them one question. How do you decide which road to take?

Answer 7:

Ask each brother, "If you were your brother, how would you say which way will lead to eternal happiness?"

Let us assume that the road to the right leads to eternal happiness. After you ask the question, both brothers will give you the same answer: "He would say that the left road will lead to eternal happiness."

· In any case, you will choose the opposite of what they said, since one is telling the truth about it being a lie and the other is lying about it being the truth.

Logic riddles

8. What number will be next in this series: 1, 11, 21, 1211, 111221, 312211, ...

Answer 8:

13112221

· Each sequence of numbers is a verbal representation of the sequence that comes before it. So, for example, starting from one, the next sequence would be "one 1" or "11". It will be followed by the sequence "two 1" or "21" and so on.

· The first digit is 1 (amount) "1" (number from 0 to 9). So if you say "One 1", the next number will be "11". Now it turned out "two 1" or "21". After that "one 2 and one 1", which gives us 1211. Then "one 1, one 2 and two 1", which gives us 111221 and so on.

Riddle 9

Four people approached a river with a narrow bridge that only 2 people can walk over at a time. It's night outside, they only have one flashlight to use when crossing the bridge.

Person A can cross the bridge in 1 minute, person B in 2 minutes, person C in 5 minutes, and person D in 8 minutes.

When two people cross a bridge together, they must pass at the speed of the one who is slower. Can they cross the bridge in 15 minutes or less?

Answer 9:

They will cross the bridge in exactly 15 minutes.

A group of 4 people must do the following:

· First A and B will cross the bridge and A will bring back the flashlight. This will take 3 minutes.

· Then, C and D will move on and B will bring back the flashlight. This will take another 10 minutes.

Finally, A and B will cross the bridge again. This will take another 2 minutes.

Riddle 10

During the last census, the man said he had three children. When asked about their ages, he replied that the product of their ages is the number 72.

The sum of their ages is the same as the house number. The census taker looks at the front door for the house number and says he still doesn't know.

The man replies: "I forgot to say that the eldest son likes chocolate pudding." Thereafter, copyist records the ages of three children. How old are the children?

Answer 10:

three children aged 3, 3 and 8.

When a man looked at the house number, he knew the sum of the children's ages. However, he could not tell the age of the children. So he had several options. Only two variants of a set of numbers when multiplied give 72: (2,6,6) and (3,3,8).

After the man said that the eldest son likes chocolate pudding, the man was able to make a choice. Since it is in the second version that the eldest son can be called.

Riddle 12

You have five bags of gold that look the same, each containing 10 bars.

One of the bags contains fake gold. The only difference between the two is that each piece of fake gold weighs 1.1 grams, while the real bar weighs 1 gram.

You have an accurate digital scale that you can only use once. How do you tell which bag is fake gold?

Answer 12:

Take 1 ingot from the first bag, 2 from the second, 3 from the third, 4 from the fourth, 5 from the fifth. If the weight ends in,1, then the fake gold is in the first bag. If the weight ends in -2, the fake gold is in the second bag, and so on.

For each person, the most difficult riddle is his own. The one over which he fought for many hours or even days. But eventually figured it out and found the answer on my own. He will never forget the clue.

But still, among those ever invented, there are those that can be confidently classified as the most intricate. They will be discussed.

The first group of puzzles: for children

Do not think that any adult can easily cope with them. Even not the most difficult riddle in the world can seriously puzzle. Moreover, there will be a big embarrassment if a child copes with it, and an adult will find it too tough.

• Life gives it as a gift twice. You have to pay for the third set. (Teeth.)
• A birch grew in the garden. There were 45 apples hanging on it. The wind blew, and 9 of them fell. How many apples are left on it? (Not at all, because apples do not grow on birches.) Note. Although if a person with creative thinking comes across, he can say that nowhere is it said that apples grew on a tree. They just hung. And it is not known how they were fixed, therefore they fell.

The list of tasks that can be described as "the most difficult puzzle" continues.

• The athlete during the race overtook the one who was in second position. Where was he? (On the second, because he did not catch up with the first.)
• The same athlete in another competition overtook the last one. What position did he get? (It is impossible to overtake the latter, if someone is ahead of him, then he was not the last.)
• This thing is thrown if it is needed. And when it turns out to be unnecessary, then it is raised. What's this? (Sea anchor.)

The second group of riddles: for those who like to count

These tasks will require mathematical calculations and a little reasoning. And then any of the most difficult riddles in the world can be solved.

• A specialist is invited to a well-known company for the position of financial analyst. He is offered a starting salary of 10,000 a month. It can be upgraded in two ways. The first promises an increase of 15 thousand a year. The second guarantees an increase of 5 thousand in six months. Which option will be more profitable? (Second.) Note. You will need to calculate the salary for an arbitrary number of years. Even the first two will suffice. In both cases, the annual salary is the same - 120 thousand. Upgrade plan for the first scenario: 120k, 135k, and so on. The second scenario will give the following alignment: 60 for the first six months and 65 for the second part of the year, as a result, 125 thousand for the 1st year. Second year: 70 and 75, which will give 145 thousand per year.
• There is a heavy anchor at the bottom of the boat. She floats on the surface of the water in the pool. What will happen to the water level if the untied anchor is thrown out of the boat? (Decrease.) Note. While the anchor lies in the boat, the part of it submerged in the water is much larger than the volume of the anchor itself.

• How to draw 4 liters of water if there are only containers of 5 and 3 available? (Fill 5, pour into 3, empty the second, pour the remaining 2 from the first into it, dial 5 again, pour 1 liter from it into a three-liter.)

The third group of riddles: to speculate

Creativity is impossible without thinking carefully and moving away from the standards that society has driven people into. Therefore, the most difficult logic puzzles turn out to be simple after they are answered.

• In a large room there is a partition, behind which there are three light bulbs. Moreover, they are not visible from the remote control with three switches. It is required to determine which one is from each light bulb. You can only go through the barrier once. The solution requires two steps. The first is to turn on one light bulb and turn it off after a few minutes. During this time, she will have time to warm up. The second action is to turn on the second light bulb. Now you can look. The one that is hot is the first. The other glows - the second. And the third - the one that was not touched at all.
• One hotel has seven floors. On the first settled 4 guests. On each subsequent floor, their number increases by 3. On which floor is the elevator button most often pressed? (On the first.)
• One person had only one match left in the box. He enters a room with a kerosene lamp on the fireplace and a gas stove. What will the person light up first? (A match.)

And this is perhaps the most difficult riddle of logic.

You need to bake 6 pies. On each side they need to be fried for 5 minutes. Only 4 pies can be placed on the pan at a time. How can I cook them in 15 minutes?

The solution consists of the following steps:

• put 4 pies for 5 minutes;
• 2 turn over and remove the others, put two more, not yet fried, for another 5 minutes;
• 2 remove (they are already ready), 2 turn over and put those that were previously removed for the remaining 5 minutes.

The fourth group of riddles: ingenuity

They require ingenuity. A savvy person will easily solve all the most complex logical riddles.

• The girl took out a ring from a cup of coffee. Why didn't the ring get wet? (Coffee in powder, granules or beans.)

• One businessman bought apples for 6 rubles, and sold them for 4. How did he manage to become a millionaire? (Before this action, he was a billionaire.)
• The steamer moored at the pier, and the 4 lower steps were in the water. The thickness and height of the steps: 5 and 30 cm. While the steamer was at the pier, the tide began, and the water arrived by 40 cm every hour. How many steps will be under water 3 hours after the start of the tide? (Still 4, the steamer will rise with the water.)

Fifth group of riddles: with a trick

In solving such problems, logic and the ability to count well will not always help. These most difficult riddles - with a catch. That is, those in which you need to look for something unusual.

• Three tractor drivers work on the collective farm, who have a brother Sergei. But he has no brothers. How can this be? (They are sisters.)
• There were 10 candles on the candlestick. The hostess blew out 3 of them. How many candles will be left by morning? (3: those that are blown out will not burn.)
• It is now 12 o'clock at night. It is raining outside. How confident is it that the sun will shine in 72 hours? (Not at all, it will be night again.)
• In what situation is it easier for a black cat to enter the house? (When the door is open.)

And some more mysteries

• It is impossible to keep it for more than 5-10 minutes. But at the same time, it weighs almost nothing (Breathing.)
• There were so many apples on the plate that there were enough for all the children. How did it happen that all the guys took one at a time, but one was left on the plate? (The latter took it along with the plate.)

And here is the most difficult riddle, which has two solutions.

The patient needs to leave for 30 days. The doctor gives him two medicines of 30 tablets. They can not be distinguished by color, taste, smell, shape and size. It is impossible to interrupt the course of treatment. Every day you need to take one tablet of each drug. One day, a person took out 1 tablet from the first package, and 2 fell out of the second. They mixed up. How can the patient follow the doctor's recommendations?

1. Take another tablet from the first one. Cut everything in half and put all the left halves in one direction, and the right halves in the other. So it turns out that in each pile there will be one of each type.

2. Again, take another pill. Grind everything into a powder and divide into two equal parts.
