DURING THE CLASSES
I. ORGANIZATIONAL MOMENT
Math has arrived
Take your seats
Find something useful to do for your head
So as not to yawn from idleness
It's useful to rack your brains
II. COMMUNICATION OF THE TOPICS AND OBJECTIVES OF THE LESSON
Teacher. Guys! Do you like to travel?
Children. Yes!
U. Today in the lesson we will not only solve problems and examples of addition and subtraction within 10, but also take a trip to the stations where unusual heroes live. Who are they?
To find out their names you need to complete tasks.
If you are ready to go on a trip, then show with a signal icon in what mood you are starting to work. We set out in search of adventure on this plane.
This card was prepared for you by the beautiful girl Bayan Sulu. Evil and insidious fairy-tale heroes turned her fiancé Goat Korpesh into Dev. Guys, we must help the beauty save her fiancé.
The route plan is posted on the board.
III. VERBAL COUNTING
U. Unexpected obstacles await us ahead. They left a letter for us, to read it, we need to arrange the numbers in ascending order
On a mobile marker board there are cards on which numbers and syllables are written.
Children put them in the right order.

U. Guys, look at this number series. Tell me, what number may be redundant? How is this number different from the rest?
D. This number is 10. The number is written using two digits.
U. What is written in the letter?
D. Have a nice trip!
U. Our caravan is ready! We sit down comfortably and hit the road. There is 1 stop waiting for us: “Numerical”.
A) Individual work“Hang the pine cones.”
U. Numbers live here. It is necessary to restore order and place the numbers in the corresponding Christmas tree. If the task is completed correctly, we will be able to find out the name fairy tale hero who is hiding in this forest.
The task is completed by 3 students.
b) Frontal work.
1. “Guess the number.”
U. I thought of a number, added the same amount to it and got 8. What number did I think of?
D. 4
2. Game “Chain”
Verification is carried out using a numeric key
c) Checking individual work.
After checking, cards appear on the board

IV. REPRESENTATION OF THE MATERIAL COVERED.
PROBLEM SOLVING.
U. We continue to travel. And our caravan is approaching the next stop “Zadachka”. The next fairy-tale hero lives at this station; to find out his name you need to start solving new tasks.
1. Compose problems using pictures and solve them orally
2. Solving problems in verse.
The teacher reads the problem, and the children show the solution on individual typesetting canvases using cut cards.

After solving each problem, a card appears on the board.3 daisies – yellow-eyes
2 cheerful cornflowers
The children gave it to their mother.
How many flowers are in the bouquet?
I have 4 books
3 cars and 3 bears,
Who will answer quickly?
How many things do I have?

And I paid 6 kopecks for a brand new pencil case.
How much did the children pay for the purchase?

U. Decipher the word.
Well done! You did an excellent job with the tasks that I prepared for you.Baba Yaga .
V. PHYSICAL MINUTE.
VI. INDEPENDENT WORK.
U. Our caravan goes to the “Independent” station, where another fairy-tale hero awaits us, whose name we will find out if we cope with the next task on our own.
Solving examples.
Examples are written on the board according to options
1 option
Option 2
Option 3
9 – 2 – 2 =
7 – 1 – 3 =
10 – 3 -2 =
3 + 3 + 1 =
5 – 2 – 2 =
4 + 3 + 1 =
4 + 2 + 2 =
6 + 1 + 3 =
8 – 2 – 2 =
We check examples of each option along the “chain”. For correct answers, each option receives a card with the name of a fairy-tale hero. (Masaic card)
U. Well done! You also did a good job with this task. Now let's connect the cards and what do you get?
D.Gin.
The teacher shows a drawing of a fairy-tale hero and attaches it to the board.
VII. GEOMETRIC MATTER
U. So, we are at the goal. And here are the Goats Korpesh. And in order to return it to its former appearance, we guys need to say: from which geometric shapes consists of a chest on which Dev sits.
D. From a triangle and a rectangle.
U. Why is the triangle so named?
D. A triangle has three angles. A rectangle has all right angles.
U. Finally, the beautiful Bayan Sulu and Kozy Korpesh are together.
VIII. RESULT OF THE LESSON.
U. What did we reinforce in the lesson?
D. Composition of numbers within 10.
U. Well done! Our journey has come to an end. You have overcome all the obstacles. While you were looking for the treasure, you worked very amicably and actively, solving examples and problems. And now we can rightfully open the chest. What's in it? Gold coins!
The teacher distributes chocolate medals.
Many problems with mathematics in primary school arise from a simple inability to add and subtract.
During preschool preparation for school and when teaching skills in 1st grade oral counting within 10 special attention should be paid.
Important!
When teaching a preschooler, you can use a variety of mathematical games. Skill for preschoolers counts within 10 needs to be brought to automaticity.
How to teach counting within 10?
To successfully develop counting within 10, we advise you to teach your child the composition of all numbers from 1 to 10. You can teach it like a song or a poem.
In the first lesson, the composition of numbers from 1 to 4 or 5 is usually learned (depending on the child’s perseverance).
| We write | Let's talk |
|---|---|
 |
|
 |

While pronouncing the composition of numbers, you can additionally clap your hands, tap a beat, throw a ball, etc.
When the compositions of these numbers are learned like poetry, we begin to ask questions separately.
For example, “Four is 1 and?”, “Three is 2 and?” etc. After oral work, we add filling in the compositions of numbers in the form of “windows”, located out of order.
For training you can download. Christmas trees, airplanes, trains, etc. can be used as such figures.
At home, if possible, try to hang these diagrams and drawings and draw the child’s attention to them as often as possible.
Simultaneously with learning the compositions of numbers, we begin to give examples from textbooks on counting within the limits of the learned numbers.
When making calculations, you need to remind the child about the composition of the number and talk through examples.
| We write | Let's talk |
|---|---|
| 2 + 3 = 5 | Two and three are five. |
| 4 − 1 = 3 | Four is one and three. |
| 1 + 1 = 2 | Two is one and one. |
In the following lessons we gradually introduce numbers from 6 to 10. It is better to learn one number per lesson.
Important!
You need to learn the full composition of the number (all combinations), i.e. from 10 = 1 + 9 to 10 = 9 + 1
To help your child count confidently and fluently, print out columns of examples and solve them for a while.
It is useful to organize competitions for the speed of solving both between children and adults.
If you want to ease school life child, we also advise you to learn the compositions of numbers from 11 to 14. You will need this when counting through tens.

GOAL: to learn to form numbers within ten from two smaller numbers; develop attention; develop the skills of self-control and self-esteem.
YOU WILL NEED:
*colored cardboard;
*simple pencil and ruler;
*bucket template;
*fish template;
*scissors;
*felt pens;
*printed numbers from 1 to 10;
*printed examples of the composition of numbers within 10:
1+7;2+6;3+5;4+4;0+8
1+8;2+7;3+6;4+5;5+4;0+9
1+9;2+8;3+7;4+6;5+5;6+4
1. Using the bucket template, cut out several different colored buckets from different colored cardstock and label each one with a printed number.
2. Using a fish template, cut out several fish from multi-colored cardboard, color them with a felt-tip pen and stick on each addition example (the composition of the number, pre-printed on the printer and cut out.
3. The game is ready! Invite your prep students to collect as many fish as possible in each bucket.
