In Russian, part of speech, denoting the number of items, the amount or order is called numeral. This article describes in detail the features of numerical, their structure, decline in cases, meaning and main problems. For better assimilation of the material, visual examples are given.

Russian language

Independent part of speech that answers questions which the? how much?and denotes the number of objects, order or quantity called nUMBER

Examples: fifth, eighth, seventeen, twenty five.

Drawn quantities can different parts of speech, but you can only write this part of speech using numbers. (Five horses - five (5) horses).

The history of the numerical system goes to the distant past formation of the Pyranceo-European language, where a tenth system of calculus was used.

Numbered issues

In Russian, there is no clear concept in Russian, there is no clear idea which verbal forms to relate to this part of speech. The fact is that by its origin, they are all relate to different basics. Conditionally, all points of view can be divided into two main groups - the study of forms in a wide or narrow understanding.

Structure of this part of speech

The composition differences such types:

Simple numerals consist of one base and describe only one digit (Four, eight, one).
Sophisticated - describe two digits that are connected in one word (twelve, fifteen, sixty).
Composite - consist of several words that are written separately (one thousand eighty eight).

What are needed for something?

To designate (call) numbers - ten, forty five, nineteen;

To indicate the subject number - five kittens, four apples;

To determine the counting order - seventh, second, twenty-first.

In the sentence, they can act as any member.

Decay by case

The name is numerical as part of speech has a category of case, and words denoting counting order vary in numbers and childbirth. The declination of cases has different types depending on the type of numeral. "Russian grammar" from 1990 indicates the existence of two species - substantive and adjective.

Substantive:

from five to ten and on the fifty, mean (six, seventeen, fifty);
numbers (two hundred, six hundred and pr.);
forty, ninety, hundred, one and a half, one and a half.

Adjective Show as adjectives and have two varieties:

The words two three four;
The words both, bothand indefinitely quantitative (Little, a lot, little, etc.).

With the change in the case of the endings, there are difficulties in the formation of forms of words and their oral speech. The norm of the literary language is the change in all parts of complex and composite forms (Fiftyst seven-day two rubles).For a sequence numerical component, there is a rule that provides for a change in such words only the last part on the principle of adjective (A thousand nine hundred and sixty for the first year - in a thousand nine hundred and sixty-first.)

Development of extracurricular activities in mathematics: "A, well, boys!"

The development of an extracurricular event in mathematics has prepared:Grishko Elena, Email: [Email Protected]

Subject: Competition of young mathematicians

Purpose:

Develop logical thinking, smelting, intelligence in non-standard situations;
Learn competently talk;
Instill interest in mathematics;
Rail a dedication and self-confidence.

B1: Good afternoon, dear friends!

B2: We are glad to welcome you on our contest of young mathematicians "A, well, boys!"

Teacher's introductory word

Dear friends! From the Small Years, each of you is studying mathematics. Who is with interest who - with indifference.

Mathematics - science in which there are many secrets. No school subject can do without mathematics. Pupils enter the chemistry office, and there is a Mendeleev table with sequence numbers of chemical elements.

B2: The teacher of history talks about the increase in production with the advent of cars and gives such an assessment: "Efficiency has increased in geometric progression."

B1: What to say there, in the lesson of music we count the tacts, dance, counting "times, two, three; once, two, three". In the lesson of the Ukrainian language, we study numerical.

B2: In short, mathematics - Queen of Sciences. The outstanding German mathematician Karl Gauss was right, saying about it back in the 18th century.

B1: The Great French Mathematician Blaze Pascal said: "The subject of mathematics is so serious that it is useful, not the mesmerous case, to do it a little entertaining."

Mathematics - subject,

What is more difficult and not,

So he is not boring to us

So that he does not bother to us.

A game will come to help us

For gymnastics of the mind.

B1: As you know, February 23 - the Day of Defender of the Fatherland! On this day, it is customary to congratulate military personnel, veterans, warriors, grandparents, boys, all men.

B2: This day is the day of respect for all generations of heroic army. And since the time of the centuries, the defenders were men, then it is truly a "male day", which all representatives of strong sex accept congratulations and receive gifts.

B1: Dear Guys, Men! Congratulations on the Day of Defenders of the Motherland!

This a momentous day is dedicated to our game.

B2: Today we have a mathematical tournament. And on the stage only knights, only future men. Man! What does this word mean. A man is courage, courage and will, strength and dexterity, incistent and resourcefulness.

B1: since ancient times, still days of the Men's warriors were defenders at home, family, homeland; Knights have always been in the post. So, we welcome you, the participants of our contest of young mathematicians "a, well, the boys!".

The word is provided to the command __

B1: Introducing the respected jury: __

All contests will be assessed today on a five-point scale.

Fans today can also earn prizes. For each correct answer, you get bonuses, after all the contests we count by anyone more, he will receive a prize.
