Troika, Troika has arrived,

The horses in that trio are white.

And in the sleigh sits the queen,

Belokosa, white-faced.

How she waved her sleeve -

All covered with silver.

“It is winter and the winter months.

- Who will name the winter months?

December is the start of winter. This is the first snow month. December is the darkest month. At this time, the longest nights and the most short days. The sun rises late and hides early. He does not rise high, and walks along the edge of the sky. And December is the last month of the year.

January is the first month of the year, but the second, middle month of winter. This is the coldest month. It is especially cold in clear weather, when the sun shines in the sky during the day, and the moon at night. In such weather, the cheeks and noses turn red and burn, as if someone were chewing on them. It's frost. For this he was nicknamed Frost - a red nose. And when the clouds come and the snow falls, it gets warmer. It's the other way around! It's not like summer! When the sun is cold, when the clouds are warm.

February is the last month of winter. In February, the deepest snow and the largest snowdrifts. This is the last month of winter.

In February, the deepest snow and the largest snowdrifts. It's also good to play snowballs in this weather. And in February, winds often blow. They blow snow off the ground. They twist it, carry it, throw it. Drift, Blizzard, Blizzard, Blizzard, Blizzard.

- Take cards with objects and circle with a blue pencil, objects that are found only in winter.

Let's check now.

Blinded from the snow

Instead of a nose deftly

Put in carrots.

Eyes - coals, lips - knots.

cold, big,

Who am i? (Snowman)

Down the top grows, up the root grows (Icicle)

III. Joint "discovery" of new knowledge.

What do you think, when nature rests? Summer, autumn, spring or winter?

So what are we going to talk about in class today?

- The theme of our lesson is "Winter: the peace of nature".

Why is winter called "peace of nature"?

- Look at the illustration and tell me what changes (signs) occur in nature with the advent of winter?

- In winter it gets cold, nature puts on a snowy outfit, rivers freeze, it snows. (It gets colder, the sky is more often covered with clouds, precipitation falls in the form of snow, the days become shorter and the nights longer).

- Listen and say what they say:

Light fluffy,

sparkling, white,

What a pure

How brave!

That's what they say about the snowflake.

Who knows how snowflakes are formed?

- Listen to the story "Snow fluffs are flying" by V. Arkhangelsky and learn a lot of interesting things about the formation of snowflakes.

Snowballs are flying.

Winter has come. A cold wind blew from the north, and snowflakes fell from the sky. They spin in the air and fall to the ground - one is more beautiful than the other! Here is a flower with six petals; here is an asterisk with six rays; here is the thinnest plate with six sides!

Scientists visited the clouds during a snowfall and saw how snowflakes form. Large flakes of snow fell under the plane, and tiny ice crystals flickered high in the sky. And as soon as the ice sank into the cloud, they immediately became light, delicate snowflakes.

Small pieces of ice in the high sky are frozen water vapor. It is everywhere in the air ocean surrounding us. In spring, summer, autumn, steam turns into raindrops, and in winter - into snowflakes.

The quieter the frosty weather, the more beautiful the snowflakes falling to the ground. With a strong wind, their rays and edges break off, and white flowers and stars turn into snow dust. And when the frost is not strong, the snowflakes roll into dense white balls, and then we say that cereals are falling from the sky.

Falling to the ground, snowflakes cling to each other and, if there is no severe frost, flakes form.

Layer after layer of snow falls on the ground, and each layer is loose at first, because there is a lot of air between the snowflakes.

- And who among you knows why the snow crunches underfoot?

- It crunches because stars and rays break under the weight of your body.

- Open textbooks on p. 88 the most real beautiful snowflake.

Fizkultminutka.

Stand up and imagine that you and I are in winter forest Frost Ivanovich.

The sun warms the earth weakly, (Hands up and down)

Frost crackles at night, (Hands on the belt, tilts to the side)

In the yard at the Snow Woman (Hands on the belt, turn around)

Whitened carrot nose. (Children show their nose)

Suddenly there was water in the river

Motionless and firm, (Jumping in place)

Blizzard get angry

The snow is spinning (Children are spinning)

Sweeps everything around

Snow white silver. (Imitate hand movements)

- Consider a photograph of a winter forest.

- Pay attention to the fact that most of the trees stand with bare branches bare from the leaves, it seems that the plants are sleeping in a deep sleep, but this is not entirely true. The trees are almost asleep, or rather, they are dozing, as they are well prepared for the cold: under the bark they have a dense cork layer that protects from the cold, the buds are covered with scales, over the summer the trees have accumulated reserves.

But not all trees shed their leaves.

What kind of trees don't shed their leaves?

— Pines and firs. Their needles are covered with a wax coating, so they are not afraid of frost.

- What difficulties do animals experience in winter, what do they eat? (students talk about squirrel, hare, fox)

“Not only the beasts prepared to survive the cold. Many birds flew away to warmer climes in autumn.

- Orioles, swifts, swallows fly to warm lands. In winter, most insects disappear, and it becomes difficult for birds to forage.

- But bullfinches and crossbills, on the contrary, come to us to spend the winter. And how they hibernate will tell us ...

What birds stay for the winter?

- Sparrows, buntings, magpies, tits.

- These birds tolerate cold well, since feathers and down are very warm clothes, and bird blood is hot, so birds are not afraid of frost.

- So what did the titmouse ask for?

– How can we help them?

The poem "Feed the birds in winter."

V. Summary of the lesson. Reflection.

No season is so magical. Whether in summer, in spring, the earth is cheerful, the leaves of trees rustle with life, the river rolls its restless waters, the meadows scream with the diversity of flowers, the chirping and squeaking of insects, birds - everything moves, everything is animated and reaches for the warmth of the sun.

Winter is different. All living things hid in the depths of the earth, holes, cracks, hollows and sleeps, waiting for spring and the sun. The trees are bare, the birds have flown away, and those that remain do not sing and fly chilly and leisurely. And the enchantress-winter gives all this dead desert new life, "motionless, dumb, wonderful life". This is the life of sleep, the time of unusually white and quiet nature.

- Guys, why do they say that “Winter is the peace of nature”, that “in winter nature sleeps”?

- Let's check your statements by reading the conclusion on p. 87 of the textbook.

Raise your hands who:

worked at full capacity;

worked well, but could have worked better. Why?

How do you end the lesson?

- Well done! You worked actively, completed tasks quickly and accurately, listened carefully to your classmates.

caregiver: “Guys, will we tell the hedgehog about winter?”.

Let's not only tell, but also draw winter for him.

4 A picture of an autumn forest with cuts is hung on the board. Nearby is a type-setting canvas, on which drawings-schemes of animals and birds are placed.

Hedgehog, do you know this forest?

Hedgehog:"He was like this when I went to bed."

caregiver: "And now the guys will tell you what it is like in winter."

Do you know how many months winter stays? And what are the names of the winter months?

December is the first month of winter.

The branches of the birches freeze,

Frost crackles at the feet

Well, the bear doesn't care:

He has been sleeping in the den for a long time.

December - cold for the whole winter the earth is cold.

December ends the year, winter begins.

January is the beginning of the year, the middle of winter.

In January, the sun smiles through tears.

Snow covered hillocks in the forest

And the ravines are covered.

Bunny jumped out of the mink -

Quiet. Cold. Belo.

February is the last month of winter.

In February, winter meets spring for the first time.

February is a fierce month, asks how shod.

In a snow cap to the eyebrows,

Even the wolf, the robber wolf.

Frightened and silent.

Hedgehog:“It turns out I slept for three months.”

Nothing, hedgehog, the guys will tell you everything now, everyone will tell you about the winter.

6 Children alternately pronounce sentences and at the same time insert the corresponding drawing-diagram into the slot in the picture.

sample story.

"It's snowing frequently in the winter. Snow caps lie on trees, roofs of houses. Snowdrifts have grown in the forest. The river was covered with ice. The trees in the forest sleep, but the animals do not sleep. Here is a bunny trembling under a bush. Flashed Red fox. The wolf ran. The squirrel came out of the hollow. Birds are not heard in the forest. They flew closer to the people. People hung a feeder for them. Here is a crow, a tit, a sparrow, a magpie, a woodpecker. These are winter birds. Children are not afraid of frost. They skate, ski, sled, play snowballs.”

The bear remained on the typesetting canvas.

caregiver: "Why did the bear stay"? (he sleeps in winter, we will not meet him in the forest).

7 Physical education: "Winter entertainment".

We play snowballs boldly

Oh what a deal!

We are not too lazy to play snowballs.

We play all day.

You better play snowballs!

Clap clap! Do not snooze!

Now throw it at me.
