To learn how to compose and understand puzzles, it is worth understanding what they are.
Word "rebus" of Latin origin (Latin rebus, with the help of things, “Non verbis sed rebus” - “Not with words, but with the help of things”). The rebus originated in France in the 15th century, and the first printed collection of rebuses, published in this country in 1582, was compiled by Etienne Taboureau. Over the time that has passed since then, the technique of composing rebus problems has been enriched with many different techniques.
So, rebus- This is one of the types of puzzles, a riddle to decipher words. Encrypted by certain rules a rebus can contain not only a single word, but also a proverb, a saying, a quote, a riddle, and even a whole short story. Words and phrases in the rebus are depicted in the form of pictures, letters, numbers, notes and other various symbols, the number of which is not limited. Solving a rebus is a whole science. When solving a rebus, you need to write down all the signs in the form of a meaningful word or sentence. Although there are several types of puzzles (literary, mathematical, musical, sound, etc.), there are some general rules their compilation and solving.
example of a rebus
GENERAL RULES FOR SOLVING PUZZLES
A word or sentence is divided into parts that can be depicted in the form of a picture or any sign. The rebus is read from left to right, less often from top to bottom. Punctuation marks and spaces are not taken into account in the rebus. If there is one word in the rebus, then it should, as a rule, be a noun, and in the singular and in the nominative case. Deviation from this rule must be specified in the terms of the rebus. If a sentence is made (a proverb, an aphorism, etc.), then, naturally, it can contain not only nouns, but also verbs and other parts of speech. In this case, the terms of the rebus must contain the appropriate phrase (for example: “Guess the riddle”). A rebus must have a solution, and, as a rule, only one. The ambiguity of the answer should be specified in the conditions of the rebus. For example: “Find two solutions to this puzzle.” The number of techniques and their combinations used in one rebus is not limited.
PUZZLES IN PICTURES
The simplest option is when the rebus consists of two pictures, which will help you create a new word. The names of the objects depicted in the rebus should be read in the nominative case, singular or plural if several objects are depicted.
rebus 1
FOB + WINDOW = FIBER
rebus 2
TRAIL + EXPERIENCE = TRAILER
rebus 3
EYE + FACES = OUTDOORS
From the last example it is clear that the picture in the rebus can have more than one name (eye and eye, bees and swarm, etc.); or the image may have a general or private name (bird - general name; swift, swallow, chicken - private name). If the depicted object has two meanings, then logically you need to determine the appropriate one. This is the most difficult thing about puzzles.
If the picture upside down, this means that the word is read “back to front”.
rebus 4
Inverted NOSE = SLEEP
If to the right or left of the picture there is one or more letters- this means that these letters should simply be added. Sometimes they are preceded by a “+” sign. Sometimes the desired object in the picture is indicated by an arrow.
rebus 5
FLASK + SA = SAUSAGE
rebus 6
Letter X + LEV = STORY
PUZZLES WITH COMMA
Commas to the right or left of the picture means that in the word guessed using the picture you need to remove as many letters as there are commas. In this case, commas in front of the picture indicate how many letters need to be removed at the beginning of the hidden word, commas at the end of the picture indicate how many letters need to be removed from the end of the word. Sometimes commas to the left of the image are drawn upside down, although this does not play a fundamental role.
rebus 7
VOL K - K = VOL
rebus 8
GA MAC - GA = MAC
rebus 9
BA SLAVE AN - BA - AN = SLAVE
The arrow pointing to the left, shown above the picture, indicates that after the word has been deciphered, it must be read backwards.
rebus 10
DRESSER - KO, read from right to left = HOUSE
PUZZLES WITH LETTERS AND NUMBERS
If it is above the picture crossed out letter, and there is another one next to it, then this letter in the word needs to be changed to the indicated one. If one or more letters are simply crossed out, then they need to be removed from the given word. The "=" sign also serves to replace one of the letters with another.
rebus 11
O R YOL = DONKEY
rebus 12
BA BARREL - BA = BARREL
rebus 13
KORO VA = CORONA
If the crossed out letter(s) stands as an independent figure, then it must be read with the addition of the particle “not”.
rebus 14
NOT TEACHING
Numbers can be used instead of pictures. If part of a word in a rebus is represented by a number, then the number is pronounced as a numeral.
rebus 15
Number SEVEN + letter I = FAMILY
rebus 16
Number STO + letter L = TABLE
We keep in mind that a number can have more than one name.
rebus 17
ONCE + FORK = FORK
rebus 18
Letter Ш + KOL + letter A = SCHOOL
rebus 19
Letter P + ONE + AR KA = MOLE
rebus 20
BY VAR + number TWO + L EC = BASEMENT
Several identical letters or other images in a row mean that you need to try to count them.
rebus 21
SEVEN letters I = FAMILY
rebus 22
THREE CATS + letter F = KNITWEAR
rebus 23
A PAIR of letters D = PARADE
Numbers next to the picture serve to number letters in a word. The number indicates the place of the letter in a given word, and the order in which the numbers are written determines the new place of this letter.
rebus 24
PINE = PUMP
rebus 25
PAINTER = GAUGE
If there are fewer numbers indicated than letters in the hidden word, this means that only the specified number of letters must be selected from the hidden word.
rebus 26
A LL IGAT O R = GUITAR
The use of crossed out numbers means that the corresponding letters must be removed from the hidden word.
rebus 27
PAL AT KA = STICK
If next to the picture there are two numbers with arrows pointing in different directions, it means that in the word the letters indicated by the numbers must be swapped.
rebus 28
Z A M OK = Smear
Roman numerals may also be used.
rebus 29
Forty A = FORTY
The use of fractions is not excluded. When a fraction is used in a puzzle, it is solved as "NA"(divide by). If the rebus uses a fraction with a denominator of 2, then it can be solved as "FLOOR"(half).
rebus 30
Z divided by K = SIGN
rebus 31
Gender of the letter E = FIELD
Crossed out sign "=" between the pictures should be read as "NOT".
rebus 32
And not Y = FROST
PUZZLES BY THE TYPE “LETTERS IN A LETTER”, “LETTERS ON OR UNDER A LETTER”
Often in puzzles they draw letters placed in an unusual angle relative to each other (one inside the other, one under or above the other, one running towards the other, one coming out of the other, etc.). This means that it is necessary to describe a picture or letter combinations using prepositions and conjunctions: “I”, “B”, “K”, “U”, “C”, “FOR”, “FROM”, “ON”, “PO” , "BEFORE" and others.
If objects, numbers or letters are depicted one within the other, then their names are read with the addition of a preposition "IN" before or between titles.
rebus 33
In the letter O the letter Z = WHO
rebus 34
Letter Z in letter O + letter N = RINGING
If one object is depicted behind another, then their names are read with the addition of a preposition "BEFORE" or "FOR".
rebus 35
Behind the letter L is the letter P = VALLEY
Usage horizontal line between pictures, letters or numbers placed one below the other means the use of prepositions "NA", "OVER", "UNDER".
rebus 36
On the letter C the letter T = NAST
rebus 37
Under the letter C kok = JUMP
rebus 38
From the letter N to the letter E + letter G = SNOW
Mathematical games puzzles in pictures for schoolchildren of grades 5-7
Klochkova Natalya Konstantinovna, mathematics teacher, Bukharayskaya Secondary School, Bukharay village, Zainsky districtDescription: This work can be used in mathematics lessons in grades 5–7. Solving puzzles can be offered to students when performing mental calculations, and can be offered as didactic material for homework. This work can serve as a guide for conducting extracurricular activities, electives. Solving puzzles develops a child’s intelligence and teaches him to find a way out. difficult situations, which, of course, will be useful in life. By solving puzzles, children replenish their vocabulary, develop attention and imaginative thinking, train visual memory, learn to write correctly and remember new words.
Target: development of intellectual abilities, formation of logical thinking.
Tasks:
Educational: teach students to solve puzzles with a mathematical theme.
Developmental: broaden students' horizons 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 pictures using letters and numbers, as well as certain shapes or objects. Rebus is one of the most interesting puzzles.
The word COMPUTER is encrypted in this picture.
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 means that you need to remove the last letter in the word. Two commas - remove two letters. In the word mosquito we remove the last two letters AP, in the word iron we remove the first letter U and the last letter G.
2. Crossed out numbers indicate that the letters standing 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. Numbers that are not crossed out indicate that the letters in places 2 and 3 must be swapped. In the word iron, the letters T and Y are swapped YUT. Now we read the word in full.
This picture encrypts the word PERPENDICULAR.
4. If the picture is upside down, then the word guessed using the picture is read from right to left. The word read is not turnip, but aper. The first letter A is removed. In the word stump, the last letter b is removed. The word whale is read backwards. 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.An “arrow” or an “equals” 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.
The word EAST is encrypted in this picture.
6.Letters, words or pictures can be depicted inside other letters, above other letters, under and behind them. Then prepositions are added: IN, ON, ABOVE, UNDER, FOR. Our letter O contains the number STO, so it turns out B-O-STO-K.
The word MAP is encrypted in this picture.
7.The numbers under the picture indicate that from this word you need to take the letters located in places numbered 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.

7 i
The number 7 is very unusual in the history of Russian culture. Fairy tales, proverbs, sayings, poems and riddles were written about her. Modern authors come up with new stories and even puzzles to make it more interesting for children to study this figure. In methods of teaching mathematics for a teacher who goes to class in 1st grade, a photo, picture, presentation are used. They can be downloaded from our website for free.
Photo pictures
Verbal aids
In lessons for children who are in 1st grade, you can use verbal aids to study mathematics. They can serve as proverbs, sayings, tongue twisters, poems, riddles where the number 7 is mentioned.
Proverbs, sayings and riddles
Proverbs, sayings, riddles - genres of oral folk art. The number 7 in them is an unusual number. It has always been associated with the motif of the harmony of the universe. For example, proverbs such as “Measure twice, cut once” indicate that the number 7 was revered as a self-sufficient number. Repeating an action seven times means achieving good luck in it. Riddles for the number 7 are mainly related to the days of the week: we also have seven of them. You can download the riddles on the website.
Of course, there is no time to devote a lot of time in mathematics lessons to the fact that the number 7 represents a certain ideal, and there is no time to delve into history. But raising children in the national spirit is simply necessary. To do this, use proverbs and sayings. These are edifying genres of folklore, containing all folk wisdom. If you tell proverbs and sayings appropriately in your lessons, children will take it for granted, and then they themselves will begin to quote them. Proverbs and sayings dedicated to the number 7 will also be associated with the perception of this number as harmonious, expressing the agreement of man and the world around him. You can download proverbs and sayings on our website.
Poetry
No matter what grade the child goes to, it will be useful for him to listen to poems about the number 7. This number is present in many modern authors, but the best can be called the poems of S. Marshak. Poems in a math lesson not only make children more interested. Poems in skillful hands develop children's memory, instill a love for native word, but it is with the help of words that we address any science. A teacher who is preparing an open lesson for an elementary class can use poems about the number 7 to diversify the lesson and attract the attention of children and guests. In children's development centers you can learn simple poems about seven by heart with children. The more you offer your children, the more you will receive from them. You can download poems by modern authors about the number 7 on our website.
It will be interesting for children to solve puzzles. It is the puzzles that develop logical thinking, ingenuity. Without developed intelligence, it will be difficult to solve the puzzles. Puzzles about the number 7 can contain an encrypted word or appearance the number itself. You can download interesting puzzles for children here.
An interesting question for children may also be: what does the number “seven” look like? Let's think about what the children might answer. She looks like a poker, an old woman, a hockey stick, etc. What would you, adults, answer? What does the number seven look like?

Visual and video aids
As a visual aid, no matter what grade the child goes to, photos with objects or animals, pictures where you need to count something or someone can be used. You can make a humorous photo of the number 7 using computer programs, combining the number with interesting objects or phenomena. You can invite each of the children to take a photo (or demonstrate existing ones) of those objects that are very similar to the number 7. See with what pleasure the children will accept this idea. The photo can also be used if a teacher who is going to a lesson in an elementary class is preparing a presentation. You can also download photos and presentation on the website.
Presentations
- Proverbs, sayings, sayings and poems about numbers
The presentation is simply necessary for a full-fledged lesson and the development of the children. Most children have a visual memory, and presentation promotes maximum learning. However, it must be built wisely. A presentation is not just a set of slides: they must be structured methodically. This means that you must be able to explain your choice of slides at any time. To ensure that your presentation is successful, we suggest that you use a presentation dedicated to the number 7, which can be easily downloaded from our website.
