Basic rules for compiling puzzles

Has it ever happened to you that your son or daughter asks you to help solve a puzzle, you take it with zeal - and you cannot solve it? We know why this happens. You should learn the basic rules for compiling such tasks.

upside down picture

If the picture shows an upside down object, then its name should be substituted backwards in the guess.

For example, the solution to this puzzle looks like this: "KA" + inverted "CAT" \u003d "KA" + "CURRENT".

Answer: "Rink".

Use of commas

This is one of the most frequent appointments. The comma in the figure indicates that a letter needs to be removed from the word. The number of commas is always equal to the number of characters to be removed.

At the same time, commas to the left of the image mean that you need to delete the first letters, and commas to the right of the picture call for discarding the last ones.

Answer: Boar.

Letter next to the picture

The letter next to the picture will definitely become part of the answer. If she stands in front of the image, then her place is at the beginning of the word, if after it, then at the end. Such tasks are simple, so it is best to start acquaintance with puzzles with them.

Answer: Screen.

Strikethrough letter or equal sign

Often a crossed-out letter is written next to the picture, and another is indicated next to it. This means that the crossed out letter in the word denoting the depicted object must be replaced by another. Follow the same principle if you see a mathematical equals sign between letters.

Answer: Cow.

Numbers under the picture

If you see numbers below or above the image, then write the name of the image and rearrange the letters in the order indicated.

Answer: Strong.

There are more complex variants of such puzzles. If there are fewer numbers below the image than there are letters in given word, then from the name we take only those characters whose numbers are indicated in the picture.

Horizontal line

The horizontal line that divides the riddle into upper and lower parts indicates that in the middle of the word there will be a preposition "above", "under" or "on".

Answer: "Ditch".

Letters inside an image

A letter or an object located inside a symbol or geometric figure means that the preposition “in” will be found in the guess.

Answers: "Crow", "Harm".

Drawing by drawing

If the images seem to be hiding one after the other, then it's time to use the word "for".

Answer: Kazan.

A letter made up of small letters

When one large character is made up of small characters, feel free to use the preposition “from”.

Answer: Downstairs.

Notes

The image of the notes in the rebus is the reason for using their names in the solution. Children who do not know the musical scale are usually given a hint.

Answer: "Share", "Beans".

Symbols holding hands

If the letters are holding hands, then we use the preposition "and" or "c" to guess.

Answer: Wasp.

Running symbols

When funny letters run away from each other or joyfully run towards, then we use the preposition "to" or "from".

Answer: Outflow.

Numbers next to letters

If the figure shows letters, and next to them are numbers, then in the guess we use the name of the number in combination with the indicated symbols.

Answer: Parking.

Some numbers can be encrypted under different names. For example, the number "1" can sound like "one", "one" and even "count".

Answer: "Fork".

Math Actions

In puzzles, you can encrypt not only words, but also numbers. For example, to guess these in appearance simple examples, you have to think carefully and connect knowledge of mathematics:

A triangle represents a number with one digit. At the same time, if you add it 4 times, you get single digit, indicated by a square, and if you add it 5 times, then a two-digit number will come out, indicated in the figure by a circle and a rhombus.

Examination:

2 + 2 + 2 + 2 = 8,

2 + 2 + 2 + 2 + 2 = 10.

Combined encryptions

Offer your student various options puzzles more often, and soon he will easily guess them on his own. Now you can move on to more sophisticated options for tasks. For example, how do you like this option?

Answer: Paddle.

Learning with interest

Well, are you convinced that solving puzzles is a whole science with its own concepts and rules? We hope we could help you figure it out. How to instill in a child an interest in such a creative way of learning? "Eureka" will give some simple tips:

• Start with the simplest tasks and gradually move on to more complex ones.
• Act unobtrusively.
• Come up with puzzles yourself and involve the child in this activity.
• Use puzzle solving as a competition with prizes for the winners - for example, on children's day birth.
• Help the baby if he cannot cope with the task for a long time.
• Praise for correct decoding and be gentle if he fails.

We are happy to dispel the myth that studying is hard and boring. We hope we succeeded! Convey a positive attitude to your young student and share your impressions in the comments to this article. See you soon!

Maths - a rather difficult science However, everyone needs to learn its basics. Without these skills and knowledge, modern world nowhere.

Elementary mathematical techniques and tasks are laid in the memory of schoolchildren in the elementary grades. And "missing" more lightweight material, to solve complex tasks becomes impossible. Long and serious math lessons make children especially restless, which means you need to submit information in a playful way, for example, using puzzles . Such tasks do not need to be forced to solve them under duress, the children themselves will willingly take on their solving.

The benefits of puzzles on a mathematical topic for the development of a child

Puzzles on a mathematical theme - these are the same riddles and puzzles that use drawings and graphics. They vary in difficulty depending on age category schoolchildren.

Rules for compiling mathematical puzzles for children

1. If you see before a word or picture comma , then you need to remove the first letter from this name . The same must be done if the comma is at the end of the word. When there are two commas near the picture, then two letters are removed, respectively. For example, the first picture shows juice - you need to remove the first letter "C", the hand - remove the syllable "ka", the letter "g" remains the same, the nose - the word remains in its entirety, five - remove the first two letters. encrypted word - "circle" .
2. If a numbers denoting the sequence of letters in a word crossed out, then they must be thrown out of it . The same goes for letters. The second picture shows a circus - remove the last letter, you need to remove the letter “A” from the word “shark”, the ready answer is “compass”.
3. When next to the picture are the numbers swapped , then in the name of the item itself, you need to swap the letters that are in sequence with the indicated numbers.
4. If a the picture is shown upside down , then the answer must be read in reverse order: from right to left.
5. For puzzles only the nominative case is used in words .
6. An arrow pointer or mathematical equals sign means that you need to replace the letters one with another.
7. in puzzles one value can be located inside another picture behind or below it. Then use the words: IN, ON, OVER, UNDER, FOR.
8. Numbers in a row next to the image , indicate that you want to use letters from this value in the specified sequence of numbers.

Here are some examples of mathematical puzzles that follow the rules given:

Under the third picture, the word is encrypted "vector" , under the fourth - "degree" , under the fifth - "two" , under the sixth - "proof" .

How to come up with a mathematical puzzle?

Following general rules composing rebuses, try to come up with simple mathematical problems to start with, using numbers and mathematical terms. And then, having mastered simple tasks a little, move on to more complicated ones. Here are some sample math puzzles with answers to inspire you and show you how to do them:

Answers: first puzzle - "diameter" , second - "five" , third - "cone" , fourth - "a task" .

Fifth picture - "algebra" , sixth - "geometry" , seventh - "ruler" , eighth - "the equation" .

The ninth riddle "diameter" , tenth - "compass" , eleventh - "protractor" , twelfth - "cone" .

Features of mathematical puzzles for elementary school

It is best to introduce the child to solving mathematical puzzles in kindergarten, in the graduation group. This will serve as an excellent warm-up before school, it will refresh the child with all the material covered with the teacher.

Just keep in mind that such puzzles should be quite easy, and include only the knowledge that the child has already learned and knows. It can be a two- or three-part puzzle, the answer of which is fraught with a simple mathematical meaning.

The same puzzles will be useful for "warming up" first-graders. Going to school is already a huge emotional burden for a child, so you shouldn’t depress learning math so complex puzzles.The following examples will do:

Mathematical puzzles for grade 1 with answers

First graders are already well aware of the numbers and simple mathematical operations that can be included in puzzles. Moreover, such puzzles are characterized by the fact that the mathematical value can be present both in the riddle itself and in its meaning. Or it may happen that the answer will be completely unrelated to this exact science. Give your child the following math puzzles:

By the name, you might think that arithmetic puzzles are ordinary puzzles in which numbers and numbers are used to encode a word. For example, "100 L" is a "table", "7I" is a "family", etc. But it's not. What I gave in the example is the usual puzzles. But arithmetic puzzles have nothing to do with ordinary puzzles at all, but it has historically developed that such puzzles are called that way.

Arithmetic rebuses are ordinary expressions and examples in which all or most of the numbers are replaced by any symbols or letters. In a letter arithmetic rebus, each letter means one specific number. In symbolic puzzles with asterisks, circles and dots, each icon can represent any number from 0 to 9. Moreover, the numbers can be repeated, some may not be used at all. The only exception is that numbers do not start with 0. Sometimes, instead of the whole number, they put the sign “?”, That is, even how many digits in the number are not known. Solving such a rebus means restoring the original record of the example.

When solving problems of this type, attention to obvious arithmetic operations, a good knowledge of arithmetic and the ability to reason logically are required. Arithmetic is not only 2+2=4. It is also a deep understanding of the principles of ordinal calculus, knowledge of the rules for expanding brackets, divisibility criteria, factoring, rules for working with fractions and powers, proportions, what are natural, prime and composite numbers, how to find LCM and GCD, how to calculate the sum of a sequence and much more other. When solving arithmetic puzzles, some knowledge of algebra may also be needed, for example, solving equations and systems of equations.

Some math problems may be too difficult to use in normal (non-math) quests, so choose them carefully.

Arithmetic puzzles, like ordinary puzzles, are endless. But all of them can be divided into several types.

pacifiers

In such arithmetic puzzles, all numbers are replaced with dots, asterisks, circles, in general, with the same symbols.

In ordinary "dummies", some numbers are often opened for a hint, or some of the numbers (which one is not known exactly) are marked with a special sign. It turns out "dummy with tips."

With pictures

Recently, puzzles have become popular on the Internet, in which a system of equations is given, where unknowns are replaced by pictures. For example, here's a problem:

It reduces to solving an ordinary system of two equations in two unknowns.

` ((3x=2y+1),(x+2=y):) `

We transfer all unknowns to the left, known to the right, multiply the second equation by 2 and subtract the second from the first equation. We get 3x-2x + 2y-2y = 1-(-4). We reduce and get x=5, which means y=7. The simplest task for a student in grades 4-5.

It all started out simple, but then the pictures became tricky. For example, this one. Nothing out of the ordinary.

We see an avocado (x), a bunch of bananas (y), oranges (z).

` ((x+x+x=30),(x+y+y=18),(y-2z=2),(z+x+y=?):) `

From the first equation x=10, we substitute x into the second, we get y=4, we substitute y into the third, we get z=1, so 1+10+4=15. Everything seems to be simple. That's how 95% of people will decide. But 5% will notice that the bottom bunch of bananas is smaller than the top ones. Top bunches of bananas = 4 because there are 4 bananas. But in the bottom there are 3 bananas, which means it should be counted as 3. And now we are carefully looking at the oranges. How many are below? One? Isn't it half? It looks like a whole orange is cut in half in the third line. And it turns out a completely different system.

` ((x+x+x=30),(x+4y+4y=18),(4y-z=2),(z/2+x+3y=?):) `

And it means that a whole orange = 2, and half an orange = 1. And it means that the correct answer is 1 + 10 + 3 = 14, not 15.

Counting oranges as whole or halves is generally not important. All the same, there will be a unit at the bottom. The main thing is that there are three bananas, not four. I note that some particularly meticulous people may argue that in the third equation there are not two halves, but a half and a whole, that is, one and a half oranges. But then the problem cannot be solved in integers, and this is ugly :) Therefore, we will not consider it that way.

There are even more confusing puzzles with even deeper tricks. For example, this one, from:

Try to solve it yourself without any hints, and then read on the site at the link, what they did there :)

Even and odd

Even numbers (0,2,4,6,8) are marked with the letter H, and odd numbers (1,3,5,7,9) are marked with the letter H.

with letters

This is a classic of mathematical puzzles, in which numbers are replaced by letters. Most often, the authors of such problems try to choose letters in such a way that words can be read in certain places. The rest of the places where words do not work out, remain, as in dummies. Sometimes hints are also left in some places.

Framework

We have 10 numbers, and in Russian there are quite a lot of words consisting of 10 different non-repeating letters. They can be used as keywords in puzzles, which some people call "keyword puzzles" and I call "Frames".

Each such problem consists of 6 equations interconnected by the signs " + », « – », « × », « : », « = ". The numbers are encrypted with letters, different numbers correspond to different letters. Usually 10 letters are used for 10 digits, but you can make an example from fewer numbers, then there will be fewer letters.

This is real mathematical problem, and quite complex, so not suitable for every quest. The problem is solved like this.

Consider the first column PZ+UU=IGE. The sum of two two-digit numbers cannot be more than 99+99=198, which means I=1.

In the equation PEP-ZT=INZ (third column), it can be seen that a two-digit number of ZT was added to the three-digit number of INP starting with 1 and again a three-digit PEP was obtained. P - not 1, since 1 is already occupied by the letter I. It turns out that P \u003d 2, because it cannot be more (because 298 is the maximum possible sum of two-digit and three-digit ones, starting with 1).

In the third line IGE + BUT = INZ, adding G tens with N tens again results in H tens. This can only be if G=0 or G=9. But if G were equal to 9, then there would be a transfer of one to the category of hundreds, and we had And and remained I. So, G \u003d 0.

So, G=0, I=1, P=2. And therefore, in the equality PZ + UU \u003d IGE, U can be either 7 or 8, because we need to add a two-digit number to two-and-something tens, and to get more than a hundred. Let Y=8. Then from YU+U=ZT it follows that T=6 and Z=9. But then in the difference PEP-ZT=INZ we get P=5. But P=2! So U≠8. Therefore, Y=7. Then from YU+U=ZT we get T=4, Z=9. Equality PZ+UU=IGE with Z=8 and U=7 gives us one more letter: E=5.

In sum, IGE + NO \u003d INZ E \u003d 5, Z \u003d 8, which means O \u003d 3. In the third column, we have already become aware of all the letters, except for H. Therefore, its value is easily found: H=6. And, finally, from the equality AxY=BUT we get A=9.

The result is: 0123456789=HYPOTENUSE. The word is guessed, it can somehow be used further in the form keyword or hints for solving the following quest tasks.

bricks

The appearance of problems of this kind resembles columns made of bricks, so I will call them "bricks".

The rules are:

each square is one number;

no number starts with 0;

the sum of the numbers of each vertical row is equal to the result of the corresponding horizontal row;

actions are made sequentially from left to right, that is, the priority rules do not work.

For example, let's solve these "bricks":

To begin with, using the rule , we will mirror and complement the results of columns and rows with respect to the diagonal. The six from the result of the second column will be copied into the second row, and the triple from the result of the first row will be copied into the first column.

Let's look at the second line. The first two numbers are single digits, which means that their sum is not more than 18, which means that only 16 can be subtracted, otherwise we will get a negative number. So the third number in the second line is 16. Let's say the sum of the first two numbers is 17. Then 17-16=1. Multiply one by a single-digit number and you get a two-digit number - this does not happen. This means that the sum of the first two numbers of the line is not 17, but 18. This means that these are both nines, 9+9-16=2. And by what single-digit number should two be multiplied to get a two-digit number with a six at the end? At 8! In total, we got the whole second row: 9+9-16×8=16. Do not forget that the order of actions is from left to right, that is, as if the record is like this: [(9 + 9) -16] × 8 = 16.

Now let's look at the second column. 16-2-9=5. That is, the third and fourth numbers in the second column add up to 5. Now let's look at the third row. The result of adding a two-digit number ending in seven and the second number must be divisible by 5, which means it must end in 5 or 0. This means that the third number in the second column must be either 3 or 8. But it must be less than five! So this is a trio. And then the fourth number in the second column is a deuce.

The result of the first row is 30 or 35, since the end is multiplied by 5. So the sum of the first column is also 30 or 35.

In the first column, the third number is 17, or 27, or 37, or so on. Let's say 27. Then 27 + 9 = 36, and this is already more than the entire possible result columns - 35. So, we have not 27, but 17. In total, we got the third row: 17 + 3: 5 × 8 = 32.

So, the result of the first line is 30 or 35. Let 35. Then the sum of the first two numbers is 7, and the third number is one. So the third column starts with one. It turns out that the fourth number in the third column should be equal to 32-1-16-5=10. But it is clear! We assumed that the result of the first line is 35 and came to a contradiction. So, not 35, but 30.

And 30 times, we think about the first line. The third number, as we have already established, is not one. So a two. There will be plenty of others. We get the first line: 1+2x2x5=30. Well, here the fourth line is already easily obtained: 3 + 2 × 9-12 = 33. And here is the result:

As you noticed, the bottom right number (the sum of the last row, which is also the sum of the last column) came at the very end of the puzzle solution. It cannot be obtained as a result of intermediate calculations, which means that these types of tasks can be used if you need to guess some three-digit number in the quest. For example, the cipher from the safe. Although not, 1000 combinations can be sorted out. Let's say you need to enter a code to disable the bomb and you can't make a mistake. Then three digits - just right.

Below is a set of 24 ready-made building blocks with answers:

locks

This type of tasks is similar to "bricks" encrypted with a certain code. The code looks as if the numbers were covered with squares, but the protruding parts of the numbers remained visible. The symbols with which the numbers are encrypted look like barn locks, which is why they are called so, “locks” (sometimes they are called “rugs”, because in general the puzzle looks like a square embroidered rug).

If each number had its own icon, then it would be full, but here one character corresponds to different numbers. And to understand which figure has disappeared where, knowledge of mathematics will help. The signs show the actions that are performed with the numbers horizontally and vertically. The sequence of actions is the same as in the "bricks" - from left to right and top to bottom no priority. And “locks” are solved, respectively, in the same way as “bricks”. And you can use them in quests, for example, to open "digital locks" on closed doors. The guessers will either have to solve such a rebus and find out the correct 4 numbers, or sort through 10,000 in order options combinations of 4 numbers until the right one comes across. For mechanical locks, this sorting method is suitable, but electronic locks can have protection against the number of incorrect attempts, so it’s better, of course, to decide, and not to select.

Let's take an example:

In the second line, the sum of the first two digits is obviously greater than two. The third digit is 3, 5 or 9. The result is a single-digit number, which means the third digit of the line is 3, and then the result can only be 9. And so the first two digits are 1 and 2. We got the second line: (1 + 2) x3=9.

Now let's look at the first column. The first digit is not equal to the second, otherwise the result would be zero. The options are: 4-1 and 7-1, and both of them are greater than 2, and the third digit is 3.5 or 9. So the first digit is 4, the third is 3, and as a result 9. We get (4-1)x3 =9.

In the third line, the third digit cannot be 7, otherwise the result would be a two-digit number. It cannot be 4 either, because if the second digit is 2 or 3, the result would be 9 or 10, and this does not fit. So the third digit of the third line is 1. Then the second digit is 2, and the result is 6, i.e. 3+2+1=6.

Rebus is a unique invention of mankind, helping to educate people in sharpness of mind, ingenuity, ingenuity. Adults sometimes like to indulge in solving such puzzles in free time, but puzzles are most fun for children. To combine the pleasant and the useful, we invite you to solve puzzles with numbers for children, which are given on our website with answers.

Puzzles are aimed at the logical development of the child.

How to solve them?

Math puzzles are not tasks that we are used to at school, although they may still contain some elements of such actions. Let's remember what a traditional rebus looks like.

Any word is taken for encryption. Then it is divided into parts and each part is encrypted. Having solved each part of the rebus separately, it is necessary to add the word.

Mathematical puzzles can be both linguistic and numerical in nature. For example, in a problem, by mathematical operations, you can calculate the required number. If mathematical puzzles with numbers for children are encrypted with words, then the task is simplified.

How can you use them?

You can solve puzzles in lessons with younger children school age, as well as preschoolers in a kindergarten or an aesthetic center, if they already know the numbers and know how to navigate them. At school, puzzles with Roman numbers can be connected to work, although it will be more difficult for children to solve them for the time being.

Of course, it is impossible to build mathematical classes completely on rebuses. But the lesson can be significantly diversified if, after several difficult tasks, a fun rebus is offered for children. If classes are held in children's center or kindergarten, then math puzzles for children can be offered daily, between games or other activities. Of course, they should be tied to the study of numbers, since children at this age are still poorly versed in numbers.

Mathematical puzzles can be given to children at home, of course, taking into account that parents will help them at home. At school on open lesson if the teacher resorts to this kind of tasks, he will surely succeed.

How to solve mathematical puzzles? Let's give some examples.

So, the first part of the word in the rebus is encrypted in the form of the word "glasses", in which you need to remove the first and third letters. So we get "chi". Further from the word "elephant" subtract the last letter. We get the word "number".

Another puzzle. The first part of the word is the note located in the middle of the first line on the stave (“mi”). The second part of the word is "nose", in which the second letter is equal to "y". If you put it all together, you get a "minus".

So, the rebus is not complicated, and younger students can also understand the principle of its construction. When the children get comfortable with the puzzles, you can invite them to come up with mathematical puzzles themselves. The kids love this kind of work. When everyone comes up with at least one or two problems, ask the others to guess. To do this, the kids must draw pictures for their puzzles on sheets of paper or on the board.

Another option for using puzzles is to prepare a competition for children's work. This can be done during Math Week or in preparation for a holiday. Hang your work with puzzles in a conspicuous place, for example, in the hall or assembly hall. It will be very interesting for parents to look at children's works and try to solve them. It is better not to hang puzzles with answers so as not to deprive the audience of intrigue.

conclusions

Puzzles are very useful tasks for children, especially if they are able to teach new things. Mathematical problems not only allow you to repeat the material by numbers, but also develop ingenuity and ingenuity.

Children are very mobile and curious creatures. Puzzles are able to awaken their imagination and sharp mind, which will surely find a solution to the problem. Give the guys more food for thought, stimulate the process of thinking, creativity. Let mathematics be closely intertwined with philology and logic, because the interaction of objects allows you to feel the connection of various disciplines from childhood, which is so necessary for the formation of a holistic picture of the world.
