TASKS ON LOGIC

Logic tasks, like mathematics, is called "gymnastics of the mind." But, unlike math, logic tasks   - This is an entertaining gymnastics, which in a fascinating 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   consists in thoroughly analyzing the condition of the problem, unraveling the tangle of conflicting connections between characters or objects. Logical 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 connection.

Even the most complex logic tasks   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 task. Not always the most obvious solution lying on the surface is the right one. But more often than not, solving a logic problem It 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 in their meaningful study. Logic tasks   for weighing, transfusion, tasks for non-standard logical thinking will help in everyday life to solve everyday problems in a non-standard way.

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

There are certain tricks solving logical problems:

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

way tables   used in solving textual logical problems. As the name implies, the solution of logical problems consists in constructing tables that allow you to visualize the condition of the problem, control the process of reasoning and help to draw the correct logical conclusions.

way graphs   consists in enumerating possible options for the development of events and the final choice of the only right solution.

flowchart method   - a method widely used in programming and solving logical transfusion problems. It consists in the fact that first, in the form of blocks, operations (commands) are allocated, then the sequence of execution of these commands is established. This is a block diagram, which is essentially a program, the implementation 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 by movements of the billiard ball along different paths. 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 classes 1, 2, 3, 4, 5, 6, 7, 8, 9.

We present you the most diverse logical tasks for 1, 2, 3, 4, 5, 6, 7, 8, 9 classes.   We have selected for you the most interesting logic tasks with answerswhich will be interesting not only to children, but also to parents.

• pick up for the child logic tasks   in accordance with his age and development
• do not rush to open the answer, let the child find himself logical decision tasks. Let him come to the right decision and you will see what pleasure and feeling of delight he will have when his answer coincides with the given.
• in the process solving logic problems   suggestive questions and indirect clues indicating the direction of thought are acceptable.

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

Solving logic problems - the first step to the development of the child.
