LOGIC TASKS

Logic tasks, as well as mathematics, is called "mind gymnastics". But unlike mathematics, logic puzzles- this is an entertaining gymnastics, which in a fun way allows you to test and train thought processes, sometimes in an unexpected perspective. To solve them, you need quick wit, sometimes intuition, but not special knowledge. Solving logic problems is to thoroughly analyze the condition of the problem, to unravel the tangle of contradictory connections between characters or objects. Logic tasks for children- these are, as a rule, whole stories with popular characters, in which you just need to get used to, feel the situation, visualize it and catch the connections.

Even the most difficult logic puzzles do not contain numbers, vectors, functions. But the mathematical way of thinking is necessary here: the main thing is to comprehend and understand the condition logical task. The most obvious decision on the surface is not always the right one. But more often than not, solving a logic problem turns out to be much simpler than it seems at first glance, despite the confusing condition.

Interesting logic tasks for children in a variety of subjects - mathematics, physics, biology - arouse their increased interest in these academic disciplines and help in their meaningful study. Logic tasks for weighing, transfusion, tasks for non-standard logical thinking will help to solve everyday problems in a non-standard way in everyday life.

In the process of decision logic tasks you will get acquainted with mathematical logic - a separate science, otherwise called "mathematics without formulas." Logic as a science was created by Aristotle, who was not a mathematician, but a philosopher. And logic was originally part of philosophy, one of the methods of reasoning. In the work "Analytics" Aristotle created 20 schemes of reasoning, which he called syllogisms. One of his most famous syllogisms is: “Socrates is a man; all men are mortal; So Socrates is mortal. Logic (from other Greek. Λογική - speech, reasoning, thought) is the science of correct thinking, or, in other words, "the art of reasoning."

There are certain methods solving logic problems:

way of reasoning, with the help of which the simplest logical problems are solved. This method is considered the most trivial. In the course of the solution, reasoning is used that consistently takes into account all the conditions of the problem, which gradually lead to a conclusion and the correct answer.

tables way, used in solving text logic problems. As the name implies, solving logical problems consists in building tables that allow you to visualize the condition of the problem, control the process of reasoning, and help draw the right logical conclusions.

graphs way consists in sorting out possible scenarios for the development of events and the final choice of the only correct solution.

flowchart method- a method widely used in programming and solving logical transfusion problems. It consists in the fact that, first, operations (commands) are allocated in the form of blocks, then the sequence of execution of these commands is established. This is the block diagram, which is essentially a program, the execution of which leads to the solution of the task.

billiard way follows from the theory of trajectories (one of the sections of probability theory). To solve the problem, it is necessary to draw a billiard table and interpret the actions of the movements of the billiard ball along different trajectories. In this case, it is necessary to keep records of possible results in a separate table.

Each of these methods is applicable to solving logical problems from different areas. These seemingly complex and scientific techniques can be used in solving logic problems for grades 1, 2, 3, 4, 5, 6, 7, 8, 9.

We present you with a variety of logical tasks for grades 1, 2, 3, 4, 5, 6, 7, 8, 9. We have selected for you the most interesting logic puzzles with answers which will be interesting not only for children, but also for parents.

• choose for the child logic puzzles according to his age and development
• do not rush to open the answer, let the child find it himself logical solution tasks. Let him come to the right decision himself and you will see what pleasure and a sense of delight he will have when his answer coincides with the given one.
• in the process solving logic problems Leading questions and indirect clues indicating the direction of reflection are acceptable.

With our selection logical tasks with answers you will really learn how to solve logical problems, expand your horizons and significantly develop logical thinking. Dare!!!

Logic problem solving — the first step in child development.

Logic tasks are perhaps the most effective tool for developing logic and thinking in both children and adults.

Solving a logic problem involves a complex thought process. This is the consistent performance of certain logical actions, work with concepts, the use of various logical constructions, the construction of a chain of precise reasoning with correct intermediate and final conclusions.

Unlike most mathematical and other types of problems, when solving logical problems, the key is not to find the quantitative characteristics of an object, but to determine and analyze the relationships between all objects of the problem.

Take a holistic approach

Among the whole variety of logical tasks, children often choose a couple of their favorite categories and immerse themselves in solving them. is that enough?

Surely most of us at least once passed tests for the level of logic. Most of them are made up of some syllogisms or trick questions. We do not offer such tests, because we know for sure that it is impossible to determine the level of development of logical thinking with the help of a dozen or two questions, even approximately. As well as developing non-standard thinking, solving only certain types of logical problems.

Classical logical, combinatorial and truth problems, regularities and mathematical puzzles, problems about figures in space and sweeps, for permutations and movement, for weighing and pouring; solved from the end, with the help of tables, segments, graphs or Euler circles - this is far from the whole variety of logical tasks, in the solution of which all kinds of mental operations are activated and creative, non-standard thinking develops.

Logic is a yummy for the mind

This is exactly what the students wrote on the blackboard before the start of one of the classes in our logic circle. What is the beauty of logical problems?

• they will be equally interesting for children who are passionate about mathematics and for “humanists”;
• many of them do not require knowledge of the school curriculum;
• even a preschooler without reading skills can solve them (for example, sudoku, rebuses, matchstick puzzles, gears and other tasks in pictures).

Children love to solve logical problems and riddles. They are interested! When I worked at school, I saw that the guys cope with the program, mechanically remembering the way to solve certain typical problems.

And tasks with asterisks immediately enlivened the class, both strong and weak students were included in the discussion process. At home, the children already could and wanted to explain this task to their parents. But even these problems with asterisks were located on the pages of the textbook in a random way, no system was developed.

Only a systematic and integrated approach creates favorable conditions for the formation of non-standard thinking. "Food for thought" should also be balanced and varied. Try it yourself and invite your children to solve just such a selection of problems. This will help identify those links in the logic that need to be worked harder.

Try it yourself

In the Logiclike online platform, created to develop logic and mathematical abilities in children aged 5-12, the authors tried to implement everything that is often so lacking for both students and teachers in school curricula. Consistency, involvement, interactivity, visualization, motivation... But first of all, it is food for the mind, the same “yummy” that makes a child think, reason, test his strength, be creative and rejoice when he manages to find the right solution.

• If you want to develop non-standard thinking and flexible logic in a child, give him a good exercise for the mind in the form of a variety of logical tasks, for which you need to use different logical laws and solution methods (method from the end, tabular method, using graphs or Euler circles, etc.). e.)
• Approach learning systematically: from theory to tasks, from simple to complex, from getting to know new types of tasks to reflection.
• Consider the specifics of thinking in children of primary school age - use visual images and visual materials.
• It is important not to impose a solution method on children, but to try to analyze it so that they themselves, through logical reasoning, find the correct answer.
• Introduce game elements into the learning process, use the learning capabilities of IT.
• Logic classes, like sports training, need regularity and a gradual increase in the complexity of tasks.

Work with your child and have fun!
