We will all hold hands and smile at each other. Guys, do you like to travel? Today I received a letter. Look, here's the envelope. Who sent it to us? Let's open the envelope and read the letter. (The teacher takes out the letter).
“Guys, I’ve already stayed with my grandfather. I think I want to go to my kindergarten again, come get me.” Your Why.
Educator:- Guys, let's go get Why?
Children: - Let's go! Educator: -I suggest you go by bus. Kamil will be the driver, and I will be the conductor today. Here I have tickets, I will hand them out to you, you look at them carefully and take a seat on the bus according to the ticket. Be careful, there is a number on the ticket. The children are seated. -I’ll check if all passengers are seated (I’m collecting tickets). -Attention, let's go (to the music "We're going, we're going" the children are going). Let's remember the rules of behavior on the bus. Music stops: stop. Educator: Oh, guys, a clearing. - Let's go out into the clearing and see if Grandpa Count lives here?
2. Composition of the number 8. Number 8.
Educator:- Guys, look who lives in this clearing? (there is a squirrel and a hedgehog on the carpet). Children: Squirrel and hedgehog. Educator: - That's right. What do they collect? Children: mushrooms. Educator: - Look how many mushrooms they collected? Let's count how many mushrooms the squirrel has collected? (7). Find the number you need and put it next to it.
-What can you say about the number of hedgehog mushrooms?
Children: A hedgehog has the same number of mushrooms as a squirrel (7)
Educator:-This means that the hedgehog has the same number of mushrooms as the squirrel, i.e. equally. What if you and I help the squirrel and add another mushroom. Do you think there are now equal numbers of mushrooms? -What can we say about mushrooms now? Children: -The squirrel has more mushrooms than the hedgehog, and the hedgehog has fewer mushrooms than the squirrel. Educator: - How many mushrooms does the squirrel have (8). Let's count together. Who knows what number represents the number 8? Children find the number 8 and show it. -Find and replace the card. Number 8 is so tasty:
She is made of two bagels. - Guys, how can you make sure that the squirrel and hedgehog mushrooms are equal? Children: Add another mushroom to the hedgehog. Educator: -How many mushrooms does the hedgehog have (8). How did you get 8 mushrooms? Children: There were 7, they added 1 more, it became 8. Educator: - Well done! We didn’t meet Pochemuchka, let’s move on. (they are going).
Educator: Stop. Let's go look for Why. Oh, guys, the bunny is sitting. He prepared a task for us, we need to guess the riddles:
1. I have no corners
And I look like a saucer
On the plate and on the lid,
On the ring, on the wheel
Who am I, friends? (circle)
2. He has known me for a long time
Every angle in it is right
All four sides
Same length.
I'm glad to introduce him to you,
And his name is... (square)
3. Three corners, three sides
Can be of different lengths.
If you stand in the corners
Then you’ll quickly jump up yourself. (triangle)
4. I am like a circle, almost like him,
But they will be flattened on both sides. (oval)
5. My angles are right
Just like a square.
But the length is on both sides
Different, guys.
Every schoolchild knows me.
And my name is... (rectangle)
While solving riddles, the teacher places images of geometric shapes on a magnetic board.
- So we met our friends. But we can meet them not only in the country of Mathematics, but also everywhere we go. Let's look at them carefully and say what these figures look like.
Game “What does the figure look like”
- You know, guys, that you can build a lot of interesting things from geometric shapes. Look at the poster and tell me what geometric shapes these drawings are made of?
Analysis of a drawing of geometric shapes.
- Well done! And now we will move on.
Educator: We stayed with you, bunny, it’s time for us to go, we are looking for Pochemuchka. Haven't you seen her? (The hare whispers in my ear: Did you see it? Where). Guys, the bunny tells me that she is playing in the next clearing. Let's go have a look soon. (children go out onto the carpet and do physical exercises.)
3. Squirrels jump on branches
Jump and jump, jump and jump!
They are often taken
High, high! (Jumping in place.)
Educator:- Oh, look, guys. Glade! Pochemuchka was playing with counting sticks. Let's play too. Sit on your knees around the clearing, here are your sticks.
-Take out 5 sticks and lay out two equal triangles from them.
-Make a house out of 6 sticks.
-Make 3 equal triangles from 7 sticks.
-Make a fish out of 8 sticks.
-Well done, guys on the task.
Once done, put the sticks in the box. (Pochemuchka’s voice is heard: Grandfather, the kids from kindergarten have come for me, I’ll go to them. Goodbye, Grandfather.)
Educator: - Why, we are so glad that we found you, we came for you. -Guys, get on the bus, let’s go to kindergarten and we’ll take Pochemuchka with us. (Let's sing
song). Well, here we are again in kindergarten. Did you enjoy our trip?
4. Summary of the lesson.
Educator:- Guys, what fairy-tale characters we met (squirrel, hedgehog, bunny). What number and figure did they help us get acquainted with? (Number and figure 8). - Draw the number 8 in the air with your finger, nose, left foot, right hand. Draw the number 8 on your palm. On the easel, find all the numbers 8 and circle with a red marker 6 5 8 4 1 8 7 2 3 8, etc. -How many numbers did you find (3). Raise your right hand, lower it to your head, stroke yourself and say: “Good girl! " -I really liked the way you played today, you answered, well done! This concludes our journey.

Don't you know me?
I live at the bottom of the sea.
Head and eight legs.
Who, tell me, am I - (octopus)
Eight legs are like eight arms
Embroider a circle with silk.
The master knows a lot about silk,
Buy flies, silk. (spider)
That's right, guys. Which one of you can tell which one? figure was mentioned in the riddles? Who listened carefully? (8)
That's right, today is Fairy Mathematics will introduce you to the number 8. (demonstration on the board numbers 8)
What does it look like number 8? (answers children) .
1. Eight has two rings
without beginning and end. (S. Marshak)
2. To this you're used to the number.
this figure - snowman. (V. Bakaldin)
3. Number eight is so delicious:
from two bagels she. (G. Vieru)
And now Fairy mathematicians invites us to sit at the tables and open our workbooks.
No. 1, page 28.
a) - Consider a series of numbers.
How much is each new the number is greater than the previous one? (On 1)
Look at number line. How to get from point 7 to point 8? (You need to take 1 step to the right, that is, add 1, increase by 1.)
(all actions are demonstrated on number line on the board)
b) - Look at the domino bones. What two parts were the 8 points divided into?
(b + 2. 5 + 3, 4 + 4.)
What happens if the dice are turned over so that the right half becomes left and the left half becomes right? (2 + b, 3 + 5, 4 + 4.)
Well done guys, you did a good job with this task, and now I suggest you rest a little.
Physical education minute
We stomp our feet, we clap our hands!
We are eyes blink-blink, we are shoulders chick-chick!
One here, two there, turn around.
Once they sat down, twice they stood up, they all raised their hands up.
One-two, one-two, it’s time for us to get busy!
Have you rested? We all sat up straight, keeping our backs straight.
Fairy mathematicians invites you to find number 8, which hid from you. Look at task #2. Where did the eight hide? (in a mouse, mushroom, pear). Trace along the outline with a red pencil numbers 8, which were hidden in the drawings. (children complete the task).
Good guys, you did it all, you did a good job. Let's do some exercises to rest your eyes.
Exercise for the eyes
Without turning your head, look to the left (to the window, to the right (to door). Repeat 5 times. Without raising your head, look up and then down with your eyes. Repeat 5 times. In a circle - 5 times. Now try to draw a figure eight with your eyes.
Well done boys! Eight is very glad to meet you. But she's not sure if you remember which two numbers can be used to make number 8.
task No. 3.
How many peas are there in the 1st picture? (8)
What parts is it made of? number 8? (7 peas are green, and 1 is yellow.)
What expression can be made from this picture? (7 + 1.) What does the first term mean? (Number of green peas.) Second term? (Number of yellow peas.)
There should be 8 peas in a pea pod. Are all the peas drawn? (No. In the other pictures there are not enough peas.)
Draw them in yellow and write the expressions under the pictures. Tell me how you are you will complete the task. (each example is spoken out by the children. As the task is completed, notes appear on the demonstration board)
7+1 6 + 2 5+3 4+4
Physical education minute
Once you bend, you straighten up,
Two bend over - pull yourself up.
Three in palms, three claps,
Three nods of the head.
Four hands wider
Five, six, sit down quietly.
Seven, eight, let's put aside laziness!
Generalization:
Guys, our Fairy really loves beautiful jewelry, so she has prepared multi-colored beads for you. look at task number 4.
Consider the strings of beads. How many beads are there on the first string? How many of them are yellow? How many blue ones? How to write this down? (7 + 1 = 8; 1+ 7 = 8)
What happens if you remove all the yellow beads from this string? (8 - 7 =1)
What if you remove not the yellow beads, but the blue ones? (8 - 1 =7)
Guys, ours lesson with the Math Fairy has come to an end. Let's thank her for our exciting class. You did a very good job today. Tell me which new one number and figure did you meet today? (answers children) . Did you like this one number, what does she look like?

1. Motivation for learning activities
- Guys, guests came to us today to see how you study. At the beginning of our lesson, let's greet our guests and wish everyone well.
You and I will go on a journey with a maple leaf.
So, let's go!
2. Updating knowledge
a) Teamwork
In a forest clearing
The proud maple tree stood
Wonderful leaves
It was decorated. (8 leaves)
On a maple tree you see leaves, on each leaf there is a number. You need to count the example and find the answer on one of the maple leaves. ( Annex 1 )
Cards:
2 + 1 4 + 1 5 – 1 3 – 1 6 + 1 2 – 1 7 – 1
(one without a number - a funny smiley face on a piece of paper)
– Arrange the numbers in ascending order: 1, 2, 3, 4, 5, 6, 7.
– Which piece of paper was left without a number? (8)
Among hundreds of different leaves
Beautiful, solemnly important,
There was one, very small, nimble baby,
A playful, cheerful, robust leaf.
– He asks you to complete his task
b) Front work
– Name the neighbors of the number “2”;
– What number comes before the number “6”?
– What is hidden behind the number “5”?
– What number is written on the card that is located between the 3rd and 5th cards;
Game “We populate the houses”(write on the board)
The teacher writes on the board:
5 6 7
/ \ / \ / \
– Now let’s complete the next task of the leaf.
c) Work in pairs
On cards (1 card on the desk)
– Solve the examples together, write down the answers, and as soon as you solve them, join your hands in a “house.”
– Let’s check (the cards are printed) ( Appendix 2
)
3 + 2 6 + 1 4 – 2 5 – 2 2 + 1
3. Working with mathematical sets(Slide 4)
– Guess the riddles, what kind of bird are we talking about?
Blue feathers, yellow belly.
This little bird is called... (titmouse)
- Listen to the problem. Create an example using the signs “+, –, =”
There were 6 titmice sitting under the maple tree, and 1 more titmouse flew up. How many tits are there?
4. Dynamic pause(physical education minute)
We are autumn leaves
We are sitting on the branches.
The wind blew and they flew.
We were flying, we were flying
and sat quietly on the ground.
The wind came again
And he picked up all the leaves.
Spun and flew
And they sat down quietly at their desks.
5. Statement of the educational problem
The wind picked up the leaf,
He lifted it up and spun it around.
A leaf flew over the house,
-Who lived in this house?
Friends of different heights
But they look alike
They all sit next to each other,
And just one toy.
– Fairytale nesting dolls lived in this house.
a) Work from the textbook (you will find a hint on page 53)
We are greeted by nesting dolls (reading a poem (p. 53)
b) Teamwork
- Look, count the nesting dolls on the board (there are 7 of them)
– Are there really 8 of them? (Collectively we count)
– What needs to be done to make them 8?
– Can we write down this expression? (Yes, 7 + 1)
– Can we write down the result? (No, since we were not introduced to the number and number 8.)
– Formulate the topic of our lesson? (Number 8. Number 8.)
– What should we learn? (Get acquainted with the number and number 8, learn the composition of the number 8)
6. Primary perception and assimilation of new theoretical educational material
1) Find the card with the number “8”.
2) What does it look like? (Matryoshka dolls look like the number “8”)
(Slide 7)
a) Number 8 is so tasty:
She is made of two bagels.b) Number 8, number 8
We always wear it on our nose.
Number 8 plus hooks–
You get: glasses.
c) You probably guessed it with me too -
Eight looks like a snow woman.
3) Connect your fingers in a figure eight.
4) Connect your hands and make a figure eight with your hands.
5) Interesting facts (Slide 8)
Let's ask nature together,
Who has eight of what?
A spider has eight legs
The stalk is thinner than a hair.
An octopus has eight legs
There are many suckers on the legs.
7. Application of theoretical principles in the conditions of performing exercises and solving problems(Slide 9)
- Let's see how people agreed to write down the sign indicating the number 8.
Number 8 consists of upper and lower small ovals. The upper oval is slightly smaller than the lower one. They begin to write it a little lower and to the right of the middle of the upper side. Draw a line to the right and up, round it in the upper right corner of the cell, then from right to left to the middle of the bottom side of the cell, round it and rise up to the starting point.
– How many elements does this figure consist of? Let's try to observe the example of how to write the number 8.
– How many elements does this figure consist of?
Showing numbers on the board in the air
Eight has two rings
Without beginning and end.
We lay out the number from plasticine on a sheet.
– How do ovals differ from each other?
Work in notebooks p. 14 (learning to write the number “8”)
8. Dynamic pause (eye exercise)(Slide 10)
9. Incorporation of knowledge and repetition into the system
a) Working with mathematical typing
b) Look carefully. Find identical nesting dolls.
c) What kind of equality or inequality can be made? (2 = 2)
10. Reflection. Self-esteem
– So the task of the leaflet is over.
- All tasks completed. Our lesson has come to an end.
– What number did we meet?
– What number did you learn to write?
– Remember and name the composition of the number 8. (Slide 11)
– You did a great job today, for those who found it easy to complete the tasks, draw Sun Those who find it difficult - a cloud, those who find it difficult - a thunderstorm.
Autumn has come to visit us
And she brought with her...
What? Say it at random!
Well, of course... (leaf fall)
– I give everyone a maple leaf as a memory of the lesson.

Formation of the number 8. Game "Day and Night"
Let's play the game "Day - Night". Remember these squares.
At night, while everyone is sleeping, various miracles happen. Let's see what happens. -Night! Children "fall asleep." The teacher adds 1 red square to the 1st row.
What changed? (A red square appeared in the first row)
How many squares are there in the first row? (8)
How did you get 8 squares? (one more square was added to 7.
It turned out 8 squares 7+1= 8)
The teacher hangs up a card with a picture of the number 8.
What does the number 8 look like? (like a snowman, glasses, 2 rings).
Guys, let's draw the number 8 with our right hand, then with our left hand, nose, eyes, etc.)
Composition of the number 8.
I will now add 1 red square to each row. How many squares will there be? (8 squares each)
Count the number of blue and red squares in row 1. What two numbers can you use to make the number 8? (1+7=8, or 7+1= 8)
Look at the 2nd row. Let's divide the number of all squares in this row into groups by color and write it as an equality. (2+ 6=8 or 6+2=8)
What equalities do we get in the 3rd row? (3+5=8, or 5+3=8)
Guys, look at the number line. What numbers are less than 4 and greater than 6?
Guys, how do you get from point 7 to point 8?
(You need to take 1 step to the right, that is, add 1, increase by 1.)
Working at tables
Now sit down at the tables.
You have 5 squares of blue and yellow on your tables. Place 4 blue squares in front of you. Add yellow squares to them until you have a total of 8 squares. How did you get 8 squares? (4+4=8). Well done!
Physical exercise.
Once - bend over, straighten up.
Two - bend down, stretch
three - three claps,
Three nods of the head
Four means wider hands.
Five, six - sit down quietly.
Guys, go to your desks. Now we will play in teams. Do you remember the name of your team? The game is called "Red Flag"
I will give each team a task, let's see who completes the task faster and will receive a red flag.
How many peas are there in the 1st picture? (8)
What parts are the number 8 made of? (7 peas are green, and 1 is yellow.)
What expression can be made from this picture? (7 + 1.) What does the first term mean? (Number of green peas.) Second term? (Number of yellow peas.)
There should be 8 peas in a pea pod. Are all the peas drawn? (No. In the other pictures there are not enough peas.)
Draw them in yellow and write the expressions under the pictures. Tell us how you will complete the task.
1st team:
The second pod contains 6 green peas. To make 8 peas, you need to add 2 more yellow peas: 6 + 2.
2nd team:
The third pod contains 5 green peas. To make 8 peas, you need to add 3 more yellow peas: 5 + 3
Both teams:
The last pod contains 4 green peas. There are still 4 yellow peas missing to eight: 4 + 4.
As the task is completed, the following entries appear on the demonstration board:
7+1 6 + 2 5+3 4+4
Summary:
Well done! Thank you! From what two numbers can you get the number 8?
(7 + 1, 6 + 2, 5 + 3, 4 + 4.)
Lesson summary:
What number did we meet today? How did you get it? (From point 7 we took 1 step to the right)
What does the number 8 look like? Well done!!!
I liked how carefully you listened to me...
They answered correctly.
We figured out how to make the number 8 from peas.
So our friend Pinocchio is also very glad that he met the number 8.
