Good day, dear friends! Do you remember what grades you got in school? I remember. There are no triples in my certificate. But during any year of study there were triples, deuces, and even cola sometimes happened. So I think, who is Alexandra, my daughter, like? Excellent student, hangs on the honor roll! Apparently those additional exercises that we do with her are bearing fruit.
Lesson plan:
Exercise 1
Very interesting exercise! Useful not only for children, but also for adults. This exercise is used as a test at the casting of radio hosts. Imagine, you come to the casting, and they say to you: “Come on, my friend, connect us a chicken with a pole.” In all seriousness, they say so!
The meaning is precisely in this, it is necessary to combine two absolutely unrelated concepts. Radio presenters need this in order to quickly and beautifully compose lead lines to songs during live broadcasts, for easy transitions from one topic to another.
Well, the kids are suitable for the development of creative, creative, quick thinking.
So how do you connect a chicken with a pole? Lots of options:
- The chicken walks around the post.
- The chicken was blind, walked and crashed into a pole.
- The chicken was strong, hit the pole, and it fell.
- The pillar fell right on the chicken.
Do you want to work out? Fine. Connect:
- chamomile with milk;
- headphones with a jellyfish;
- moon boots.
Exercise 2. Word Breakers
If in the previous exercise we connected, then in this we will break one long word into many short ones, consisting of letters of a large word. According to the rules, if a letter occurs once in a long word, then it cannot be repeated twice in short words.
For example, the word "switch" breaks down into:
- tulle;
- key;
- beak.
I don't see any more options, do you?
You can break any long words, for example, “holiday”, “picture”, “towel”, “polar explorer”.
Exercise 3. Puzzles
Solving puzzles helps to think outside the box, creatively. Teaches the child to analyze.
Rebuses may contain images, letters, numbers, commas, fractions, placed in a very different order. Let's try to solve some simple puzzles together.
- On the first we see the syllable "BA" and "barrel". Connect: BA + Barrel = Butterfly.
- On the second, the principle is the same: Baran + KA = Bagel.
- The third is more difficult. Cancer is drawn, and next to it is “a = y”. So in the word cancer, the letter "a" must be replaced with the letter "y", we get "hands". To this we add another "a": hand + a = hand.
- The fourth rebus with a comma. Since the letter “A” is the first, the guess word begins with it. Next, we see the “fist”, after the picture there is a comma, which means that the last letter must be subtracted from the word “fist”. Let's get "cool". Now we combine everything together: A + kula = shark.
- The fifth rebus is only at first glance difficult. You need to remove the letter “and” from the word “saw”, and read the word “cat” backwards. As a result, we get: pla + current = handkerchief.
- The sixth, fully alphabetic rebus. Everything is clear with the first and last letters, 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 + WTO + P \u003d AUTHOR.
Trained? Now try to solve the puzzle yourself.
You can share your answers in the comments. You will find many puzzles in children's magazines and.
Exercise 4. Anagrams
Can an orange be turned into a spaniel and vice versa? "Easily!" anagram lovers will answer. Even Magic wand will not need.
An anagram is a literary device that consists in rearranging the letters or sounds of a certain word (or phrase), which results in another word or phrase.
Just as easily, a dream turns into a nose, a cat into a current, and a linden into a saw.
Well, shall we try? Let's make it so:
- the "carriage" flew to the stars;
- "word" grew on the head;
- "lace" learned to fly;
- "atlas" became edible;
- "pump" settled in the forest;
- "mote" became transparent;
- the “roller” was placed on the table before dinner;
- "bun" learned to swim;
- "chamomile" was spinning by the lantern on summer evenings;
- "Park" could not live without water.
Exercise 5. Logic problems
The more logic puzzles you solve, the stronger your thinking becomes. After all, 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 the simpler ones:
- Kolya and Vasya solved problems. One boy decided at the blackboard, and the other at the desk. Where did Vasya solve problems if Kolya did not solve them at the blackboard?
- Three old grandmothers live in the same entrance, on the third, fifth and seventh floors. Who lives on what floor, if grandmother Nina lives above Valya's grandmother, and Galya's grandmother lives below Valya's grandmother?
- Yura, Igor, Pasha and Artem finished in the top four in the running competition. Who took what place? It is known that Yura did not run first or fourth, Igor ran after the winner, and Pasha was not the last.
And the next three problems Sashulya brought from the Mathematical Olympiad. These are tasks for the third grade.
“The gardener planted 8 seedlings. Of all but four, pear trees have grown. All but two pear trees grow pears. Pears from all fruit-bearing pear trees except one are not tasty. How many pear trees have tasty pears?”
“Vasya, Petya, Vanya wear ties of only one color: green, yellow and blue. Vasya said: "Petya does not like yellow." Petya said: "Vanya wears a blue tie." Vanya said: "You are both deceiving." Who prefers what color if Vanya never lies?
And now attention! A task of increased difficulty! "On the backfill," as they say. I couldn't solve it. I suffered for a long time, and then I looked at the answers. She is also from the Olympics.
“The traveler needs to cross the desert. The transition lasts six days. The traveler and the porter who will accompany him may take with him a supply of water and food for one person for four days each. How many porters will the traveler need to realize his plan? Enter the smallest number."
If you still fall asleep on any task, then contact me, I will help)
Exercise 6. Match puzzles
Matches are not toys for children! A tool for training thinking. For safety reasons, I suggest replacing matches with counting sticks.
These simple little sticks make very complex puzzles.
First, let's warm up:
- fold two identical triangles from five sticks;
- of seven sticks, two identical squares;
- remove three sticks to make three identical squares (see picture below).
Now more difficult:
Move three sticks so that the arrow flies in the opposite direction.
The fish also needs to be turned in the other direction, while shifting only three sticks.
After shifting only three sticks, remove the strawberry from the glass.
Remove two sticks to make two equilateral triangles.
The answers can be found at the end of the article.
Exercise 7
And now let's work as Sherlock Holmes! Let us seek the truth and discover lies.
Show the child two pictures, on one of which depict a square and a triangle, and on the other a circle and a polygon.
And now offer cards with the following statements:
- some figures on the card are triangles;
- there are no triangles on the card;
- there are circles on the card;
- some of the figures on the card are squares;
- all shapes on the card are triangles;
- there are no polygons on the card;
- There are no rectangles on the card.
The task is to determine whether these statements are false or true for each picture with figures.
Such an exercise can be carried out not only with geometric shapes, but also with images of animals. For example, put a cat, a fox and a squirrel on the picture.
Statements can be as follows:
- all these animals are predators;
- there are pets in the picture;
- all the 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 things. We use them. Sometimes we do not pay any attention to the instructions that are attached to these items. And it also happens that there are simply no instructions for some very necessary items. Let's fix this misunderstanding! We will write the instructions ourselves.
Take, for example, a comb. Yes, yes, the usual comb! That's what we got with Alexandra.
So, instructions for using the comb.
- A comb is a device for making hair smooth and silky, made of plastic.
- Use a comb should be with increased shaggy and curly.
- In order to start combing, approach the comb, gently take it in your hand.
- Stand in front of a mirror, smile, bring the comb to the roots of your hair.
- Now slowly move the comb down to the ends of your hair.
- If there are obstacles in the form of knots on the way of the comb, then run the comb over them several times with weak pressure, while you can scream a little.
- Each strand of hair is subject to processing by a comb.
- Combing can be considered finished when the comb does not meet a single knot on the way.
- After combing, it is necessary to rinse the comb with water, put it in a place specially designated for it.
- If a tooth has broken off a comb, you need to throw it in the trash.
- If all the teeth of the comb have broken off, send it after the tooth.
Try writing instructions for a pot, or slippers, or a glasses case. It will be interesting!
Exercise 9. Making up a story
Stories can be composed in different ways, for example, based on a picture or on a given topic. By the way, this will help. And I suggest you try to compose a story based on the words that must be present in this story.
As always, an example.
Words are given: Olga Nikolaevna, poodle, sequins, turnip, salary, gray hair, castle, flood, maple, song.
Here's what happened to Sasha.
Olga Nikolaevna walked down the street. On a leash, she led her poodle Artemon, the poodle was all shiny. Yesterday he broke the lock on the locker, got to the box of glitter, and poured it all over himself. And Artemon gnawed through the pipe in the bathroom and made a real flood. When Olga Nikolaevna came home from work and saw all this, gray hair appeared in her hair. And now they were going for turnips, as turnips calm the nerves. And the turnip was expensive, worth half the salary. Before entering the store, Olga Nikolaevna tied the poodle to a maple tree and, singing a song, went inside.
Now try it yourself! Here are three sets of words:
- Doctor, traffic light, headphones, lamp, mouse, magazine, frame, exam, janitor, paper clip.
- First grader, summer, hare, button, gap, bonfire, Velcro, shore, plane, hand.
- Konstantin, jump, samovar, mirror, speed, sadness, trip, ball, list, theater.
Exercise 10
We have already worked as detectives. Now I propose to work as a police officer. The fact is that the words in well-known proverbs and sayings violated the order. We will deal with violators of the order. Try to arrange the words the way they are supposed to stand.
- Food, comes, time, in, appetite.
- You will pull out, not, labor, from, a fish, a pond, without.
- Measure, one, a, one, seven, cut, one.
- And, ride, sled, love, carry, love.
- Waiting, no, seven, one.
- Word, cat, and, nice, kind.
- One hundred, a, rubles, have, don't, have, friends, a hundred.
- Falls, not, apple trees, far, apple, from.
- Flowing, stone, not, water, recumbent, under.
- Autumn, consider, by, chickens.
I want to clarify. We don't do this on purpose. That is, it doesn’t happen that I say: “Come on, Alexandra, sit down at the table, let’s develop thinking!” No. All this in between times, if we go somewhere, we go, before going to bed instead of books. It is very interesting to engage in, so you don’t have to force anyone.
Well, now the promised answers to matchstick puzzles!
Puzzle Answers
About two triangles of five matches.
About two squares out of seven.
We get three squares.
Expand the arrow (watch the color of the sticks).
We turn the fish.
And about two equilateral triangles.

Of course, parents do not always want to bother their precious child and come up with the most difficult riddles for him. Nevertheless, such questions, which require reflection, are useful and necessary for children and adults, regardless of age.
Why ask a child difficult riddles
Moms and dads may wonder whether it is worth misleading a child and including difficult tasks in the program. However, having studied the information on how productive the most difficult riddles are for children different ages, parents will immediately change their minds. Logic and trick puzzles are needed for the following reasons:
These are just some of the factors that indicate that children definitely need difficult questions that need to be answered. This will help you develop fully and be literate.
What should be the riddles
It is clear that complex riddles are somewhat different from simple logical questions. It is necessary to think over the program of a developmental lesson with such tasks in advance so that the process goes smoothly and without a hitch. The hardest riddles should be:
- With a trick.
- Are ambiguous.
- The kind that deserves a lot of thought.
- Difficult riddles should be selected according to the age of the child. This will help boys and girls find answers according to their level of knowledge. It follows that kids should not make very difficult riddles; for the smallest, it is better to choose questions with a trick. For older children, you can choose questions such as for adults.
It is worth considering the above factors when choosing logical questions for your child.
Logic puzzles for the little ones
For children up to school age you can take into account the following riddles:

Such complex logic puzzles for the little ones will cause a whirlpool of emotions and interest. The most important thing is to give the child hints, thanks to which he will be able to find the correct answer.
Difficult riddles with a trick for schoolchildren
School-age children can pick up questions even harder. Very complex ones can be:
You are in a running race. When you overtook the one who ran last, what did you become?
(This cannot be, because the last runner cannot be overtaken, because he is the last one and there cannot be someone else behind him)
Three car owners had a brother Alyosha. But Alyosha did not have a single brother, how is this possible?
(Perhaps if Alyosha had sisters)
What will you become in a row if you overtook the second runner in line?
(Many will answer first, but this is wrong, because having overtaken the second runner, a person will become the second)
Such complex riddles with a trick will certainly appeal to schoolchildren. After thinking about the answer, it will be easy to voice it.
Adult riddles with a trick
Sometimes adults are like children. Therefore, they will also like very complex riddles. For people older than school age, you can ask the following logical questions:
There is a tram with five passengers. At the first stop, two passengers got off and four got on. No one got off at the next stop, ten passengers got on. At another station, five passengers entered, one got off. On the next - seven people left, eight people entered. When there was another stop, five people got off and no one came in. How many stops did the tram have?
(The answer in this riddle is not so important. The bottom line is that all participants will most likely count the number of passengers and hardly anyone will decide to count the stops)

The third prisoner escaped normally and was never seen again. What's wrong with this story?
(There are no sharks in the river, the prisoner could not be dragged by the hair, because they shave their heads)
Such riddles will appeal to adult participants in the event.
How to motivate a child to participate in a developmental activity
It is clear that children definitely need motivation in order for participation in the game to be exciting and desirable. It is enough just to promise the baby some kind of present and, of course, hand it over at the end of the game.
Logical tasks can be attributed to a kind of gymnastics for the mind. The solution of such problems develops logical and non-standard thinking, ingenuity, memory, which are necessary for every person. Logic tasks are different. For example, mathematical, tricky, ingenious, in the form of puzzles.
____________________________
Logic tasks
Task 1: Imagine that a golfer has hit the ball. After hitting the ball rolled, rolled across the field and eventually rolled not into the hole, but into a steel pipe dug vertically deep (several meters) into the ground. The ball ended up at the very bottom of the pipe (several meters from the ground).
Can you please tell me how a golfer can get his ball out without much effort without having to dig out such a long pipe?
Task 2: Try to understand by what rule the following numerical sequence is formed:
1
11
21
1211
111221
312211
13112221
1113213211
Task 3: Continue with the following sequence of letters:
S O N D Y F M …
Task 4: Alexander has his own pet shop selling birds. If he places one bird in each cage, then one bird is not enough for the cage. If Alexander places two birds in each cage, then one cage will remain free. How many cages and birds do you think are in Alexander's pet store?
Task 5: Imagine that you have a large barrel of kvass. In addition, you have two empty bottles of 3 and 5 liters. How to use these bottles to measure exactly one liter of kvass?
Task 6: Alexander weighs half as much as Dmitry, and Nikolai weighs 3 times more than Alexander. Try to determine how much each of them weighs if together they weigh 360 kilograms?
Task 7: Below is the sequence of letters. There is no rule for the order in which this sequence is built. However, two letters are missing for completeness, what are these two letters?
I S F A M O N D I
Answer to problem 1: The golfer needs to pour water into the pipe to the brim, then the ball itself will float to the surface.
Answer to problem 2: Each next number describes one previous one. For example: the number in the second line "11" says that there is one unit in the previous line (1(one)1(unit)); the number in the third line "21" says that there are two ones in the previous line or 2(two)1(ones); the number in the fourth line "1211" says that in the previous line there is one two and one one or 1 (one) 2 (two) 1 (one) 1 (one). And so on.
Answer to problem 3: The letter a". Here the sequence of the first letters in the names of the months of the year is used, starting from September: September, October, November, December, January, February, March. Therefore, the next letter will be "A" - April.
Answer to problem 4: Alexander has four birds and three cages in the pet shop.
Answer to problem 5: First, we fill a 3-liter bottle with kvass from a barrel, then pour all 3 liters from a 3-liter bottle into a 5-liter bottle. Then again from the barrel we pour the kvass in addition to the 3-liter bottle. Then pour kvass from it into a five-liter bottle until it is full. And as a result, exactly 1 liter of kvass will remain in a 3-liter bottle.
Answer to problem 6: Nikolay = 180kg, Dmitry = 120kg, Alexander = 60kg. Solution: let Alexander's weight = x (x), then Dmitry's weight = 2x, and Nikolai's weight = 3x. Therefore, we get the equation: (x + 2x + 3x) = 360kg. Equivalently: 6x \u003d 360 kg, from where x \u003d (360 kg: 6) \u003d 60 kg. After that, the weight of each of them is easily calculated.
Answer to problem 7: Letters "M" and "A". The group of letters consists of the first letters of the names of the months of the year. All of them are located randomly, but two more letters are missing for completeness (after all, there should be 12 of them).
Trick puzzles
Task 1: If Jack does not drink at work, then for some reason all his employees begin to think that he is a bad worker and a slacker. Why do you think?
Task 2: Three friends went to play billiards together. They stayed there for 2 hours, after which they were billed 15 dollars. Friends chipped in for 5 dollars, paid 15 dollars to the cashier and went home. But the head of the billiard room was their friend, and when he found out that his friends had been billed, he told the cashier to catch up with them and return them $ 5 (for friendship). The cashier decided to give his friends only 3 dollars, and take 2 for himself. He did just that. As a result, each of the friends paid $4, for a total of $12. Plus, the cashier kept 2 dollars. The total is 12 + 2 = $14. Where do you think the other dollar went?
Task 3: Sveta has pets: cats and dogs. Of all her animals, only one is not a dog, while all of her pets, except for one, are cats. How many cats and dogs do you think Sveta has?

Task 6: An inspector inspecting a certain school noticed that whenever he asked a class a question, all the students raised their hands in response. Moreover, although school teacher chose a different student each time, the answer was always correct. How did it work out?
Task 7: Returning home from fishing, the fisherman met his friend, who inquired about his catch. But, since our fisherman, in addition to fishing, was also a great lover of all kinds of riddles, he answered his friend as follows: “If I add half the catch and another ten fish to the number of fish I caught, then my catch would be exactly a hundred fish.” How many fish did the angler catch?
Answer to problem 1: Jack works as an alcohol taster.
Answer to problem 2: As the calculations are indicated at the end of the puzzle condition, it is, of course, impossible to count in this way. So, friends paid 12 dollars, of which 10 dollars went to the cashier, and 2 dollars remained with the cunning cashier. As a result, there is no missing dollar. Here is the answer to this missing dollar puzzle.
Answer to problem 3: Sveta has only one dog and only one cat.
Answer to problem 4: Only one apple, because after one apple is placed, the basket will no longer be empty.
Answer to problem 5: This person is a midget, and only reaches the button on the 17th floor with an umbrella or asks someone to press this button.
Answer to problem 6: The teacher had previously agreed with the students that they would volunteer to answer, regardless of whether they know the answer or not. But those who know the answer should raise their right hand, and those who do not know should raise their left. The teacher each time chose a different student, but always the one who raised his right hand.
Answer to problem 7: Let's solve the problem from its end. If we subtract the extra 10 fish, 90 fish remain. The number 90 contains three equal parts, of which two are the actual catch, and the third is an additional half of the actual catch. Therefore, this additional half of the catch is 90:3=30 fish, and the catch itself is 30x2=60 fish.

Task 7: People who came to one village were often surprised by the local fool. When given the choice between a shiny 50-cent piece and a crumpled five-dollar bill, he always chose the coin, even though it was worth ten times less than the bill. Why did he never choose the bill?
Answer to problem 1:"The quick brown fox jumps over the lazy dog" - this sentence contains all the letters of the English alphabet.
Answer to problem 2: The portrait shows the son of this gentleman.
Answer to problem 3: The plane was on the runway.
Answer to problem 4: The sergeant placed sentries like this: one in the corners and three in the middle of each of the 4 sides, you get 5 on each side of the camp. The captain placed sentries like this: two in the corners and two in the middle of each of the 4 sides, you get 6 on each side of the camp. The colonel placed sentries like this: three in the corners and one in the middle of each of the 4 sides, it will turn out 7 on each side of the camp.
Answer to problem 5: To begin with, we will denote the husbands by the letters A, B, C, and the wives will be denoted by the letters a, b, c. Then the following actions follow in order: 1) first, “a” and “b” swim to the second shore, 2) then “a” returns and takes “c” to the other shore, 3) “c” returns and remains with “C”, and “A” and “B” swim to the other shore, 4) “B” and “b” return to the first shore, “b” remains, and “B” and “C” swim to the second shore (as a result, all the husbands ended up on the second shore), 5) then "a" takes "b", 6) and finally "C" takes "c".
Answer to problem 6: Very often they argue like this: a beetle crawls to a height of 3 meters (5m - 2m) in 24 hours. Therefore, he will climb to a height of 9 meters in 3 days, i.e. by 6 am on Wednesday. But a more correct answer is different: at the end of the second day (Tuesday at 6 am), the beetle will be at a height of 6 meters, and on the same day it can still crawl 5 meters, which exceeds the required level of 9 meters. It is not difficult to calculate that the beetle will reach 9 meters already on Tuesday at 13:12.
Answer to problem 7: The “fool” was not so stupid: he understood that as long as he chose the 50-cent coin, people would offer him money to choose from, and if he chose the five-dollar bill, the offers of money would stop and he would receive nothing.
Math problems
Task 1: In the 19th century, a teacher asked his students to calculate the sum of all integers from one to one hundred. There were no computers and calculators then, and the students began to conscientiously add up the numbers. And only one student found the correct answer in just a few seconds. It turned out to be Carl Friedrich Gauss, the future great mathematician. How did he do it?
Task 2: There are nine coins on the table. One of them is fake. How can you find a counterfeit coin with two weighings? (A fake coin is lighter than a real one.)
Task 3: One fisherman bought himself a new 5 foot rod. He has to get home by public transport, in which the rules prohibit the transport of objects longer than 4 feet. How to pack a fishing rod to travel to public transport without breaking the rules?
Task 4: There are 9 kg of cereals and a pan scale with weights of 50 g and 200 g. Try to weigh 2 kg of this cereal in three steps.
Task 5: In one city, a new district of 100 houses was built. The sign makers have made and brought a pack of new signs with house numbers from 1 to 100. Count the number of all 9s found in these signs (numbers 9 and 6 are different numbers).
Task 6: When the book was published, it took 2,775 digits to number its pages. How many pages are in the book?
Task 7: To get paint orange color need to mix paints yellow color(6 parts) and red (2 parts). How many grams of orange paint can be obtained (maximum) with 3 grams of yellow and 3 grams of red paint?
Answer to problem 1: The future mathematician identified 49 pairs of numbers: 99 and 1, 98 and 2, 97 and 3 ... 51 and 49. In total, each pair of numbers was one hundred, and there were two unpaired numbers 50 and 100. Therefore, 49x100 + 50 + 100 = 5050.
Answer to problem 2: First weighing: put three coins on each scale pan. If the scales are balanced, then two of the three remaining coins are taken for the second weighing. If a counterfeit coin is on the scales, then it is clear which scale pan it is on. If the scales are balanced, then the remaining unweighed coin is counterfeit. If at the first weighing one of the cups outweighs the other, then the counterfeit coin is among the coins, the weight of which is less. Then by the second weighing, we determine which of the coins is counterfeit.
Answer to problem 3: The rod must be packed in a box 4 feet long and 3 feet wide (placed diagonally on the box).
Answer to problem 4: It is necessary to hang the cereal into two equal parts of 4.5 kg each; then hang one of these parts in half again, that is, 2.25 kg each, and subtract 250 g from one of these parts using the two available weights. Thus, you will get a weight of 2 kg.
Answer to problem 5: The correct answer is 20 nines.
Answer to problem 6: The first 9 pages require 9 digits. From the 10th to the 99th page (90 pages) 90x2=180 digits are required. From the 100th to the 999th page (900 pages), 900x3 = 2700 digits are required (300 digits for every hundred pages with three-digit numbering). Therefore, 2700+180+9=2889 digits are needed for 999 pages. We went through (2889-2775)/3=38 pages. Total: 999-38=961 pages were in the book.
Answer to problem 7: It can be seen from the condition of the problem that yellow paint is required 3 times more than red. Therefore, having 3 grams of yellow paint available, you need to take 1 gram of red paint. That is, when mixed, orange paint will turn out 4 grams.
