Mathematical puzzles. Open lesson-game. Theme "Oh, this trigonometry" Mathematical puzzles 7

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 must be mastered by each person, since it is simply impossible to live without this knowledge in the modern world.

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 even in 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 kids?

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 fascinating activity, non-standard thinking is formed in children. 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. In particular, the following puzzles are suitable for older preschool children:

Mathematical puzzles for grades 1-4

Primary school students 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.

Rebus is a logic game in which you have to guess the answer from the picture. The latter depicts objects, animals and plants, letters and numbers. Their relative position matters. Even for fidgets, puzzles can be an exciting activity if presented in a playful way. For example, you can offer to teach a child how to solve spy ciphers.

And from the simplest picture puzzles for preschool age to get to relatively complex ones. We assure you: if your child gets carried away and learns to turn on logical thinking, over time you will already learn from him how to solve riddles in pictures.

Puzzles are invented on a huge variety of topics. The main thing is that every word, letter and object that serves as an answer to the picture should already be familiar to the baby.

How to solve puzzles for children with letters in pictures?

If you are interested in puzzles, then most likely you know the advantages of these logical puzzles. They develop memory, ingenuity, speed of thinking, the ability to navigate the situation and apply the knowledge already gained.

To teach a child of 6-7 years old how to solve tasks correctly, first explain the rules to him. No need to insist that he remember everything at once. Chances are you don't even know them all. It is better to explain one or two a day and reinforce them with thematic tasks. The latter can be printed (more convenient for outdoor activities) or shown from the monitor. In the next lessons, it is also better not to offer too much material. It is important to explain to the child that he first needs to correctly identify and name the object shown in the picture. And only then apply the rules in relation to this word.

So, let's read the basic rules! In particular, we will define what a comma, a strikethrough, an inverted object and other subtleties in pictures mean.

What does a comma mean at the beginning or end of a rebus?
A comma at the bottom or at the top before the picture means that one letter at the beginning must be discarded from the name of the depicted object. Accordingly, we see two commas - we discard the first two letters. These icons are very common.
What does an inverted comma at the beginning or end mean?
The rules for inverted commas are similar to the rules for regular commas (see previous paragraph).
What do the crossed out and added letters mean?
A crossed out letter in the picture means that it must be excluded from the name of the drawn object (and another one should be added, if it is indicated). Added to the left or right of the picture - you need to add it to the word at the beginning and at the end.
What do the numbers in the puzzles mean?
The numbers can have two meanings. Are they above the word? To guess the answer, you need to rearrange the letters from place to place in the indicated order. The name of the number can be part of the word (often use "one hundred", "five"). A crossed out number means that a letter with such a serial number must be excluded from the word. It should be remembered that some numbers, as well as objects, can have several names (the unit is “count”, “time”, “one”).
What does the plus sign mean?
If there is a plus sign between the words (symbols), then they must be added to each other. Sometimes “+” means the preposition “to”, the right one is chosen according to the meaning. The "equal" sign (for example, A=K) indicates that all the letters "A" in the word should be replaced by the letters "K".
Vertical or horizontal line in assignments?
The horizontal line means simultaneously “under”, “above”, “above” and “on”, depending on the context. Used with letters or pictures when one part is drawn below the line, the other is above. Sometimes denotes a fraction (half of something, that is, "half-").
Arrangement of letters in the picture and prepositions
It is important to look at the relative position of the letters. If they are placed one inside the other, then the preposition "in" is added to their names. One letter is drawn after another - meaning the preposition "for" or "before".
The item in the picture is drawn upside down? To get an answer, you need to read the word backwards. Children 6-7 years old can turn short words in their minds. True, the number of such tasks is quite limited.

Most often, several rules are used simultaneously in puzzles. It is believed that at 6-7 years old children are already familiar with the letters, they clearly know their names. If a younger student has not yet encountered commas, teaching him a new icon will not be particularly difficult.

Examples of puzzles in pictures for children 6-7 years old with answers

Children 6-7 years old and less perceive the material much better in relation to some memorable event. Riddles about animals will be solved with delight if you offer them to your child the day after visiting the zoo. A first-grader girl who is eager to enter a music school will be interested in musical puzzles. And a child, a boy impressed by the planetarium, will like pictures about space.

About animals and birds

When giving children a task about birds or animals, make sure that he has already come across such names of animals, and also understands everything that is shown in the picture.

Rebuses about family, about mother

Who is the sweetest for a child, if not mommy! And who does he happily meet every time, except for mom and dad? Children will love to recognize and guess grandmother, grandfather, sister and other relatives in encrypted pictures. Print or draw colorful pictures and start having fun while teaching your child!

About sports, about health

Puzzles about work, health, sports, professions and many others can be used as thematic game aids. In the graduation group of the kindergarten, the first grades of school or at home, are classes or conversations planned on one of the topics? A riddle in the form of a picture will allow you to learn the material better than an ordinary faceless story. Kids will be interested in non-standard presentation of material.

Fairy tale puzzles

Fairy tales with familiar characters, modern or classic cartoons are an inexhaustible storehouse of inspiration. If the child is not very interested in logical riddles, you can try to captivate him by guessing his favorite characters. There are many more mysteries on this topic than are given as an example. Knowing the interests and favorite fairy tales of your child, you can create puzzles in the form of applications yourself.

Math games puzzles in pictures for schoolchildren in grades 5-7

Klochkova Natalya Konstantinovna, teacher of mathematics, MBOU "Bukharai secondary school", village of Bukharai, Zainsky district
Description: This work can be used in mathematics lessons in grades 5-7. Solving puzzles can be offered to students during oral counting, can be offered as didactic material for homework. 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.

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.
