Mathematical puzzles for 6 years old. Mathematical puzzles


Mathematics - quite a difficult science , however, everyone needs to learn its basics. Without these skills and knowledge in modern world nowhere.

Elementary mathematical techniques and problems are ingrained in the memory of schoolchildren in the elementary grades. And having “missed” more lightweight material, it becomes impossible to solve complex tasks. Long and serious mathematics lessons make children especially restless, which means information must be presented in a playful way, for example, using puzzles . Such tasks should not be forced to be solved under pressure; children will willingly take on solving them themselves.

The benefits of mathematical puzzles for child development

Math puzzles - these are the same riddles and puzzles that use drawings and graphics. They vary in difficulty level depending on age category schoolchildren.


Rules for composing 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, two letters are removed accordingly. For example, the first picture shows juice - you need to remove the first letter "C", a hand - remove the syllable "ka", the letter "zh" remains, a nose - the word remains as a whole, five - remove the first two letters. Encrypted word - "circle" .
  2. If numbers , indicating 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, from the word “shark” you need to remove the letter “A”, the ready answer is “compass”.
  3. When next to the picture there are 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 the picture is 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 a mathematical equal sign indicates that you need to replace the letters one by one.
  7. In puzzles one value can be located inside another picture , behind it or under it. Then use the words: IN, ON, ABOVE, UNDER, BEHIND.
  8. Numbers in a row near the image , indicate that you need to use letters from this value in the specified sequence of numbers.

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

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

How to come up with a math puzzle?

Following general rules When creating puzzles, try to come up with simple math problems first, 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 - "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 your child to solving mathematical puzzles as early as kindergarten, in the graduating group. This will serve as an excellent warm-up before school and will refresh the child on all the material covered with the teacher.

You just need to take into account that such puzzles should be quite easy, and include only the knowledge that the child has already learned and knows. It may be a puzzle of two or three parts, the answer to which has a simple mathematical meaning.

These same puzzles will be useful for “warming up” first-graders. Entering school is already a huge emotional burden for a child, so you shouldn’t depress learning mathematics so much. complex puzzles.The following examples are suitable:


Mathematical puzzles for grade 1 with answers

First graders already have a good knowledge of numbers and simple mathematical operations that can be included in puzzles. Moreover, it is characteristic of such puzzles that mathematical meaning can be present both in the riddle itself and in its meaning. Or it may happen that the answer is completely unrelated to this exact science. Offer your child the following math puzzles:

Mathematics is one of the most difficult sciences, which gives schoolchildren a lot of trouble during their studies. At the same time, mental calculation skills and various mathematical techniques must be mastered by every person, since without this knowledge it is simply impossible to live in the modern world.

Long and complex mathematics lessons, especially in the lower grades, tire children excessively and do not allow them to fully assimilate information. To prevent this from happening, children need to submit the necessary information in the form fun game, for example, in the form of mathematical puzzles.

Such puzzles can vary in difficulty level, 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 study. In this article we will tell you the benefits of mathematical puzzles for children and 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 of different levels of complexity, which are compiled using graphic elements. Solving such riddles is an extremely exciting activity that you can spend more than one hour doing. In addition, older children enjoy composing mathematical puzzles for their classmates and friends, and this also allows them and contributes to the development of logical thinking.

In cases where the puzzles are quite difficult riddles, boys and girls have to seriously “rack” their brains to find the correct answer. In the process of this exciting activity, children develop innovative thinking. In the future, this skill will be useful for finding possible ways out of different life situations.

Finally, math puzzles give kids a boost good mood, and if the child solves them not alone, but in the company of friends or relatives, they additionally contribute to socialization and strengthening relationships.

Examples of mathematical puzzles for preschoolers

Mathematical riddles for preschoolers should be the simplest. They usually include 2-3 elements, and their answer is a simple mathematical term or the name of a number. In particular, for older children preschool age The following puzzles are suitable:

Mathematical puzzles for grades 1-4

Students primary 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, the text of which contains 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 primary schoolchildren have yet to become familiar 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 those in grades 8-9, math puzzles should already be quite complex - so that the children would have to work hard to decipher them. Otherwise, such problems will not be able to interest and captivate schoolchildren for a long time, and therefore will be absolutely useless.

Instructions

Before you start solving complex tasks, practice on simple example: CAR+CAR=CONSTRUCTION. Write it down in a column, it will be easier to solve. You have two unknown five-digit numbers whose sum is a six-digit number, so B+B is greater than 10 and C is equal to 1. Replace the symbols C with 1.

The sum A+A is a single-digit or two-digit number with a unit at the end, this is possible if the sum G+G is greater than 10 and A is equal to either 0 or 5. Try to assume that A is equal to 0, then O is equal to 5 , which does not satisfy the conditions of the problem, because in this case B+B=2B cannot equal 15. Therefore, A=5. Replace all A's with 5's.

The sum O+O=2O is an even number and can be equal to 5 or 15 only if the sum H+H is a two-digit number, i.e. H is more than 6. If O+O=5, then O=2. This solution is incorrect, because. B+B=2B+1, i.e. O must be an odd number. So O is equal to 7. Replace all O's with 7's.

It is easy to see that B is equal to 8, then H = 9. Replace all letters with the found numeric values.

Replace the remaining letters in the example with numbers: G=6 and T=3. You got the correct equality: 85679+85679=171358. The rebus has been solved.

When subtracting, also start with units. If the number of one or another digit is being reduced less number subtracted, then borrow 1 ten or a hundred from the next digit, etc. and do the calculations. Put a dot over the number you borrowed from so you don’t forget. When performing actions with this digit, subtract from the reduced number. Write the result below the horizontal line.

Check the calculations are correct. If you added, then subtract one of the terms from the resulting sum, you should get . If you subtracted, then add the resulting difference with the subtrahend, you should get the minuend.

note

The digits of the numbers must be located one below the other.

In linear algebra and geometry, the concept vector defined differently. In algebra vector om is the element vector nogo space. In geometry vector om is an ordered pair of points in Euclidean space - a directed segment. Above vector We have defined linear operations - addition vector ov and multiplication vector but for a certain number.

Instructions

The work vector and a for a number? is called the number?a that |?a| = |?| * |a|. Obtained by multiplying by a number vector parallel to the original vector y or lies on the same straight line with it. If?>0, then vector s a and ?a are unidirectional if?<0, то vector s a and?a are directed to different .

A rebus is a special riddle in which the desired word is enclosed in pictures containing various letters and numbers. In the pictures you can also see other signs that will help you read the word correctly. Solving puzzles is a very exciting activity that will help you warm up before difficult work. To do this, you must remember a number of simple rules.

Instructions

The names of any objects depicted in the picture are read only in the nominative case.

Sometimes a drawing may have several names (for example, paw or leg). An item can also have a specific or general name. For example, flower is a general name, and a specific name is rose. Therefore, if you can correctly guess the object shown in the picture, then consider that the hardest part is over. The simplest and most popular method of solving puzzles is drawings in parts. That is, you first need to write down all the names of the objects in order, and then put the text together from them.

One or more inverted commas may be drawn to the right of the item - this means that one or more letters need to be removed at the beginning or end of the word, respectively.

If there are numbers above the picture, the letters in the word must be read in a certain order - exactly in the order in which the numbers appear.
