This work can serve as a guide for extracurricular activities, electives. Solving puzzles develops the child's ingenuity and teaches him to find a way out of difficult situations, which, of course, will come in handy in life. Guessing puzzles, children replenish their vocabulary, develop attention and imaginative thinking, train visual memory, learn to write correctly and memorize new words.
Target: development of intellectual abilities, the formation of logical thinking.
Tasks:
Educational: teach students to solve puzzles with mathematical themes.
Developing: to expand the horizons of students in the field of mathematics.
Educational: to cultivate a conscious attitude towards mathematics as an important subject.
Introduction:
A rebus is a puzzle in which a word is encrypted. This word is given in the form of drawings using letters and numbers, as well as certain figures or objects. Rebus is one of the most interesting puzzles.
In this picture, the word COMPUTER is encrypted.

There are certain rules for solving puzzles.
1. A comma at the very beginning of a word indicates that you need to remove the first letter in this word, and a comma at the end - remove the last letter in the word. Two commas - remove two letters. In the word mosquito we remove the last two letters AR, in the word iron we remove the first letter U and the last letter G.
2. Crossed out numbers indicate that the letters in this place are removed. In the word five, we remove the second and third letters, that is, YAT. If letters are crossed out, they are also removed from the word.
3. Non-crossed out numbers show that the letters in place 2 and 3 must be swapped. In the word iron, the letters T and Yu are interchanged with YUT. And now we read the word in full.
In this picture, the word PERPENDICULAR is encrypted.

4. If the picture is upside down, then the word made up with the help of the picture is read from right to left. It is not the word turnip that is read, but aper. The first letter A is removed. In the word stump, the last letter b is removed. The word whale is read the other way around. In the word chair, the first two letters ST are removed. The names of all objects depicted in the rebus are read only in the nominative case.
5. "Arrow" or "equal" sign indicates that one letter must be replaced by another. In our case, in the word tick, the letter T must be replaced with the letter D. Now the word can be read in full.
On this picture the word EAST is encrypted.

6. Letters, words or pictures can be displayed inside other letters, above other letters, under and behind them. Then prepositions are added: IN, ON, OVER, UNDER, FOR. We have the number STO in the letter O, so we get B-O-STO-K.
In this picture, the word CARD is encrypted.

7. The numbers under the picture indicate that from this word you need to take the letters that stand in the places under the numbers 7,2,4,3,8 and compose them in the order in which the numbers are located. In the word cheesecake, you need to take the letters 7-K, 2-A, 4-P, 3-T, 8-A. You can read the word.
Let's try to solve some puzzles from the field of mathematics.

All tasks are decorated with bright pictures and interestingly illustrated, so the puzzles will captivate the children. And you can try to make it yourself. It will be even more interesting.

Mathematics is one of the most difficult sciences, which gives schoolchildren a lot of trouble during their studies. At the same time, the skills of oral counting and various mathematical techniques need to be mastered by each person, because without this knowledge in modern world it's just impossible to live.

Long and difficult math lessons, especially in the elementary grades, overly tire the children and do not allow them to fully assimilate the information. To prevent this from happening, kids need to provide the necessary information in the form of a fun game, for example, in the form of mathematical puzzles.

Such puzzles can be of different levels of complexity, so you can start solving them as early as kindergarten. In addition, children almost always really like puzzles, and you don’t have to force your child to work out. In this article, we will tell you what is the use of mathematical puzzles for children, and we will offer several examples for boys and girls of different ages.

What are math puzzles and why are they so useful for children?

Mathematical puzzles are different levels of complexity, which are compiled using graphic elements. Solving such riddles is an extremely exciting activity, for which you can spend more than one hour. In addition, older children are happy to make mathematical puzzles for their classmates and friends, and this also allows them and contributes to the development of logical thinking.

In cases where puzzles are rather complex riddles, boys and girls have to seriously “break” their heads in order to find the correct answer. In the process of this exciting activity children develop out-of-the-box thinking. In the future, this skill will come in handy for finding possible ways out of various life situations.

Finally, mathematical puzzles give the children a charge of excellent mood, and if the child solves them not alone, but in the company of friends or relatives, they additionally contribute to socialization and strengthening of relationships.

Examples of mathematical puzzles for preschoolers

Math puzzles for preschoolers should be the simplest. Usually they include 2-3 elements, and their answer is a simple mathematical term or the name of a number. Particularly for older children preschool age fit the following puzzles:

Mathematical puzzles for grades 1-4

Students elementary school are already familiar with numbers and some other mathematical terms, so they can use them to compose and solve various puzzles. At this age, riddles are most often used, in the text of which there are numbers and other similar elements. Moreover, the answer to such puzzles can be anything, including those not related to mathematical science.

At the same time, mathematical terms can also be encrypted in such problems, but in this case they are quite complex concepts that younger students have yet to get acquainted with. The following mathematical puzzles with answers are suitable for students in grades 1, 2, 3 and 4:

Mathematical puzzles for students in grades 5-9 with answers

For secondary school students, especially grades 8-9, math puzzles should already be quite complex - such that the guys have to work hard to decipher them. Otherwise, such puzzles will not be able to interest and captivate schoolchildren for a long time, which means they will be absolutely useless.

A rebus is a riddle in which the desired word or phrase is depicted as a combination of figures, signs, letters, i.e. "objects". One of the main difficulties in solving puzzles is the ability to correctly name the object depicted in the figure and understand how the fragments of the picture relate to each other. It is necessary to take into account the presence of synonyms, the letter "fraction" can be read in different ways. In addition to knowing the rules, you also need ingenuity and logic.

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 their free time, but puzzles are the 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?

Mathematical puzzles are not puzzles 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.

A selection of materials on the topic

Answers to this rebus: swift, family, magpie, pillar.

How can you use them?

You can solve puzzles in lessons with children of primary school age, as well as preschoolers in 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.
