To draw the correct drib on the coordinate exchange of the demand:

Growth of a single lead to the equal number of parts, according to the number, which stand in the standard.

From the ear to the left, there are a number of parts, according to the number, which is in the fraction of a fraction.

Note: If you want to draw on the coordinate promenade, you need to divide a single view into 9 equal parts and add 5 such parts.

I.Organizational moment. Psychological mood of the class. (1 min.)

Hlops, I will laugh at you, you will laugh at me. It seems like a laugh and a garnishing mood is waiting for you to help you get in touch with your employees and seek garnishing results.

Trying to reconsider the miracle rule for the current year.

II.Closing the news by those(Revision of the theory, in the foreground):

1) Sleep well. (7 min.)

1. What is the name of the coordinate exchange?

(A ray with a single one is called coordinate exchange.)

2. So also a single interval?

(Vidrizok, if the girl was taken for an odd one, to be called single vidrizkom.)

3. What is the coordinate of the point?

(The number, like the point of the coordinate exchange, is called the coordinate of the point.)

4. How many numbers can be displayed on the coordinate promenade?

(On the coordinate promenade, it is possible to represent natural numbers with dots, a number o, specific fractions and changes of numbers.)

5. How can I make the correct picture of the drіb on the coordinate promenade?

A. Growth is a single interval per equal to the number of parts, similar to the number, which is worth a fraction in the denominator.

B. From the ear to the left, there are a number of parts, according to the number, which is in the fraction of a fraction.

6. Are there correct and incorrect fractions at any intervals?(Correct fractions are represented as dots from 0 to 1, and incorrect fractions are right or 1, otherwise they go with it.)

2) Viconannya zavdan. (5 min.)

1. Children from the skin group get a large number of squares,

of skin fraction on interactive dosages.

Visually start the most and the least fraction ..

2. (Armchair zavdannya vikonano on doshtsi. Explain why? (5 min.)(NOC).

8. Reflexion (2 minutes)

Would you be more honored at the lesson?

How difficult are your winners?

Yak vi їh poured?

Will the lesson end with the mood?

I ask you to evaluate for additional help:

posvoiv - green color sticker,

additional help is required - a sticker of a black color,

zasvoiv - stick of erysipelas.

For a visual image of a fraction on a coordinate exchange, it is important to correctly vibrate to a single image.

The most reliable option for the coordinate exchange of a fraction is to take a single interval from style cliques, which is a denominator of fractions. For example, if it is necessary to draw on the coordinate exchange fractions with a denominator of 5, a single interval is more beautiful than taking a total of 5 cells:

In general, the picture of fractions on the coordinate promenade is not difficult: 1/5 - one clip, 2/5 - two, 3/5 - three, 4/5 - chotiri.

It is necessary to mean on the coordinate exchange fractions with different banners, bazhano, the number of clits in a single form was added to all banners. For example, for the image on the coordinate exchange of fractions with 8, 4 and 2 denominators, manually take a single sample before gin in all the cells. For example, on the coordinate exchange it will be necessary to break it down, a single interval is broken into the style of parts, such as a banner, and we take such parts of the style, such as a number. To create a drib 1/8, a single interval can be broken into 8 parts and 7 parts are taken. If you want to make a change to the number 2 3/4, you can see two pieces of one piece on the cob, and the third piece is split into 4 parts and we take three of them:

Another butt: the coordinate prod with a fraction, the banners of which are 6, 2 and 3. At the same time, in the quality of a single one, by hand, take a variety of pictures:
