Target:

• To teach children to compare objects in size (size, length, height, width), using the words: wider - narrower, longer - shorter, higher - lower, more - less. To learn by imposing and on the "eye" to compare contrasting objects.
• Develop the ability to analyze, compare, classify objects by size, carry out the serialization of objects.

"Big small"

The teacher lays out the cards face up in front of the child. Tells a story like this.

Different objects lived in one fairy-tale land. Each item had a brother or sister, very, very similar friend on a friend. They differed only in size - one large and the other small. And then one day I got up strong wind. He mixed up all the objects, scattered them in different sides. Let's help you find the residents fairyland their brothers and sisters. If we find it right, they will take the handles. And if we make a mistake, they will not give hands to each other. Shall we try?

The child needs to take one card with any object, name it and find a pair for it. If the choice is made correctly, then the locks on the cards will allow you to connect the cards into a paired picture.

"My size"

(D / and “Once upon a time there was a circle”)

The teacher offers the children pictures of different subjects. The child chooses only pictures with large items, regardless of the shape, but discards medium and small ones (other options are possible).

"More less"

(D / and “Once upon a time there was a circle”)

The teacher arranges the cards in a chaotic order with pictures up, takes one card and asks the child to find 2 more with the same geom. figures, but different sizes. The child compares the depicted figures by size, using the concepts of "more, less".

"The Doll Comes to Visit"

The teacher offers the child one doll and 6 dresses and says that you need to help Tonya find her dress. The doll tries on all the outfits, commenting: “This dress is not enough for me, I need more, etc.” The child must help Tonya find her dress.

"Who is faster"

(D / and "The doll is visiting")

The teacher distributes dolls to the children and says: “Who will find his outfit faster?”. Children find the appropriate dress size (first out of 3 offered, and then out of 6).

"Spread to size"

(D / and "4th extra")

The teacher selects for the game cards with objects that differ in contrast in size. He lays them out in random order and asks the child to distribute the cards by size, choose from them the largest, the smallest.

"Wonderful bag"

The bag contains items of various sizes. The teacher offers the child to get only large (small) objects. The child determines the size of the object by touch.

Games with Gyenesh blocks:

• Find all shapes like this one (by size).
• Find a figure not like this one (by size).

Abstract of a lesson in mathematics in the second junior group.

Abstract of the lesson on FEMP in 2 ml. group.

Topic: Comparison by size.

Purpose: Formation of skills of educational activity.

Program content: To form the ability to compare two objects in length by application. To consolidate the concepts of "one", "many". Develop motor skills of hands, thinking, attention, the ability to reason. Fix the color of objects. Cultivate a desire to help others.

Equipment: demonstration material: red and blue cubes, two strips of different sizes, a pointer, two planar houses, two toys - bears, two buckets, cones, a ribbed board, a card with vegetables.

Handout: two strips of different sizes, colored pencils.

Course progress.

1. Motivational and incentive stage.

Guys, today I suggest we go on a train journey.

Children stand one after another, give a signal and come to the land of toys.

2. Organizational-search stage.

Look how many toys are here. What is on this table? (dice)

How many? (lot)

Children are invited to take one blue cube.

How many cubes did Vova take (one). How many cubes does Tanya have? (one). How much is left on the table? (no one).

Then the children put back, one cube at a time and name the actions (I put one cube)

We also have a lot of items in the group, let's call them (flowers, toys, tables, windows, etc.)

Tired, let's sit down and rest.

On the board are two strips of different colors and sizes.

Look at these tracks and say they are the same or different? How to find out? What should be done? (compare)

Look, I will attach one track to another, trim their ends on the left. You see, one end protrudes, which means that the red stripe is longer and the green one is shorter.

The teacher runs his hand along the paths. Then he calls several children to show a long and a short track. Children also show the length of the tracks with their hands.

Fizkultminutka.

And now, in order, we do exercises together:

Hands to the sides, bent, raised the top, waved,

Hid behind their backs

Turned over the left shoulder, over the right shoulder.

They sat down together, touched their heels.

Raise up on tiptoes, put your hands down.

Independent activity.

You have tracks on the tables of different lengths, compare them, and paint the long track in red, the short one in green.

What color did you paint over the short track?

Now let's continue our journey. We are going with you to the forest. To get to the forest faster, which path will we take? (short)

Children get up, walk along the plank-path and enter the forest. They meet two cubs in the forest who are crying because they got lost. And one teddy bear scattered cones.

Let's help him collect the cones in a bucket.

Didactic game "collect cones"

Guys, now let's show the bears the way home.

The children again walk along the plank-path and stop in front of two houses of different sizes.

Summarizing.

What signs can be used to collect items? (By size, by color, by shape).

Can you tell me the colors? (Red, yellow, blue, white, green, black).

Can you tell me the shape of geometric shapes? (□ ○∆).

Can you tell me the size of the items? (Big small).

Task 3.

"Assemble the mosaic."

material for the task. Geometric shapes of different colors and sizes. Mosaic boards.

Children lay out a mosaic, name the composed objects and their purpose.

Final part.

Today in the lesson we repeated the signs of objects. Which?

(Shape, color, size).

Guys, if you can distinguish objects by shape, color and size, you can make not only individual objects, but real pictures. How did our student Anya Ivanova from the 9th grade.
