Of course, parents don’t always want to bother their precious child and come up with the most complicated riddles for him. Nevertheless, such questions, the answer to which you need to think about, are useful and necessary for children and adults, regardless of age.

Why ask your child complex riddles?

Moms and dads may wonder whether it is worth misleading their child and including difficult tasks in the program. However, having studied the information about how productive the most complex riddles are for children of different ages, parents will immediately change their previous opinion. Logic and trick riddles are needed for the following reasons:

These are just some of the factors that indicate that children are bound to have difficult questions to answer. This will help you develop fully and be literate.

What should riddles be like?

It is clear that complex riddles are somewhat different from simple logical questions. You should think through a program of developmental classes with such tasks in advance so that the process goes smoothly and without hitches. The most difficult riddles should be:

• With a catch.
• Ambiguous.
• Those that are worth thinking about the answer to.
• Complex riddles should be selected according to the child’s age. This will help boys and girls find answers according to their level of knowledge. It follows that children should not ask very complex riddles; for the little ones it is better to choose trick questions. For older children, you can choose the same questions as for adults.

It is worth considering the above factors when choosing logical questions for your child.

Logic riddles for little ones

For preschool children, you can take into account the following riddles:

Adult riddles with a trick

Sometimes adults are like children. Therefore, they will also like very complex riddles. People over school age can be asked the following logical questions:

A tram with five passengers is traveling. At the first stop, two passengers got off and four got on. At the next stop, no one got off; ten passengers got on. At another station, five passengers entered and one exited. On the next one, seven people came out and eight people entered. When there was another stop, five people got off and no one got on.

Explanation is inevitable

On Tuesday at about 10 o'clock in the morning a stranger burst into Inspector Warnicke's room. He was extremely excited. His hands were shaking, his tousled hair stuck out in all directions. A few minutes later, having lit a cigarette and calmed down, the visitor began his story: - This morning I returned from vacation. I had to shake on the train all night. I didn’t get enough sleep and, when I came home, I decided to lie down on the sofa. Because of fatigue, I did not immediately notice that the piano had disappeared from the room, and the coffee table and armchair had been moved out of place. On this piece of paper I drew a plan for the arrangement of furniture in the room before I left. “Here’s what, dear,” said Inspector Warnicke, quickly glancing at the drawing, “First of all, it’s absolutely clear to me that you didn’t have a piano at all.” Now let's find out why you needed this lie. Why did Inspector Warnicke doubt the veracity of the visitor's story?

LOGIC PROBLEMS

Logic problems, just like mathematics, is called “mental gymnastics.” But, unlike mathematics, logic problems is an entertaining gymnastics that allows you to test and train your thought processes in a fun way, sometimes from an unexpected perspective. Solving them requires intelligence, sometimes intuition, but not special knowledge. Solving logic problems consists in thoroughly analyzing the conditions of the problem, unraveling the tangle of contradictory connections between characters or objects. Logic problems for children- these are, as a rule, whole stories with popular characters, which you just need to get used to, feel the situation, visually imagine it and catch the connections.

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

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

In the process of solving logic problems 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 his work “Analytics,” Aristotle created 20 patterns of reasoning, which he called syllogisms. One of his most famous syllogisms is: “Socrates is a man; all people are mortal; So Socrates is mortal." Logic (from ancient Greek. Λογική - speech, reasoning, thought) is the science of correct thinking, or, in other words, the “art of reasoning.”

There are certain techniques solving logical problems:

way of reasoning, with the help of which the simplest logical problems are solved. This method is considered the most trivial. During 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.

table method, used in solving text logic problems. As the name suggests, solving logical problems involves constructing tables that allow you to visualize the conditions of the problem, control the reasoning process, and help you draw correct logical conclusions.

graph method consists in sorting through possible options 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 a flowchart, which is essentially a program, the execution of which leads to the solution of the task.

billiards method follows from trajectory theory (one of the branches of probability theory). To solve the problem, you need to draw a billiard table and interpret the actions by 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 a wide variety logic problems for grades 1, 2, 3, 4, 5, 6, 7, 8, 9. We have selected for you the most interesting logic problems with answers, which will be of interest not only to children, but also to parents.

• choose for the child logic problems in accordance with his age and development
• take your time to reveal the answer, let the child find it himself logical solution tasks. Let him come to the correct decision himself and you will see what pleasure and feeling of delight he will have when his answer coincides with the given one.
• in progress solving logic problems Leading questions and indirect clues indicating the direction of reflection are acceptable.

Using our selection logic problems with answers you will really learn to solve logical problems, expand your horizons and significantly develop logical thinking. Go for it!!!

Solving logical problems - the first step towards child development.

E. Davydova

Logic is the art of arriving to an unpredictable conclusion.

Samuel Johnson

Without logic it is almost impossible to enter our world brilliant discoveries of intuition.

Kirill Fandeev

A person who thinks logically stands out nicely against the backdrop of the real world.
