Progress of classes in the senior group of kindergarten
Introductory part
Educator. - Children, listen to the riddle:
“Seven brothers are equal in age, but have different names.” ( Days of the week)
How many days of the week are there in total? Who wants to name them?
Which one is the first? Seventh? Fifth?
Wednesday is what day of the week? And Saturday?
What day of the week is it today? What is it in order? (Tuesday)
Educator. -Today the Queen of Mathematics invites us to her kingdom. Tell me, why do we need mathematics?
Children's answers.
Then let's complete a few of its tasks to test your knowledge.
1 task
The first thing she would like to know is whether you know Seasons.
What time of year is it now?
How many seasons are there in total? Name them.
How many months are there in each season?
Name the autumn, winter, spring and summer months.
How many months are there in a year?
Queen Mathematics would like to check if there are enough problems on everyone's desks.
Children are counted in pairs.
Queen Mathematics offers new problems. (Children sit at tables)
Main part
Next task from the queen:
2 task
Drawing up examples from drawings.
What mathematical symbols are needed to solve the examples?
When do we use the "+" sign? (When we add or increase the quantity)
When is the “-” sign used? (When we subtract or reduce a quantity)
What other sign do we need? (=)
Queen Mathematics would like to remind you of the rules of addition and subtraction.
To perform addition, you need to add another part to one part and find the whole.
To perform subtraction, you need to subtract a part from the whole and get the remaining part.
Who is shown in the picture?
How many kittens were there?
How many came running? What action must be performed to find out how many there are in total?
Why do you think it should be added?
How can I write this down as an example? mathematics in kindergarten
Let's create an example using the following figure.
How many birds were there in the feeder?
How many flew? What action must be performed to find out how many are left? Did all the birds fly away or only some of them? How to find the second part if we know how many birds there were in total?
Why do you think it should be taken away?
How can I write this down as an example?
Now complete the tasks on your desks yourself. (Drawing up examples from pictures) (The teacher checks the correctness of execution and offers to check each other)
Queen Mathematics is pleased with your work and she decided to invite you for a walk in the “Geometric Forest”, but before we go there, she would like you to find out who lives in it.
3 task
Graphic dictation “Who lives in the forest.” (difficulty selected)
Move from the point according to the diagram.
The teacher offers to help each other. (Children who completed it earlier than others are asked to color the picture)
Who do you think lives in the forest?
Yes, it's a wolf. He invites us to a forest clearing.
Physical education lesson “Forest clearing”
We came to a forest clearing,
Lifting your legs higher
Through bushes and hummocks,
Through branches and stumps.
We walked for a very long time,
Our little legs are tired.
Now let's sit down and rest,
And then we'll go for a walk.
(They walk, raising their legs high, squat down, stand up and continue moving.)
4 task
Didactic game “Let’s help plant trees”
The geometric forest contains trees of various shapes, sizes and colors. You need to take seedlings (geometric shapes) and plant them in three alleys:
1 alley - trees that have no corners, large in size, red and yellow.
2nd alley - trees that have four or fewer corners, small in size, blue and green in color.
3rd alley - trees that have five or more corners, large in size, orange and purple.
Look, there is a diagram in front of the alley, plant your tree on the desired alley.
Why did you plant your tree on this alley?
Educator. - Queen Mathematics was pleased with your knowledge and skill. But she would like to ask you...

Explanatory note
The workbook is intended for first graders. The manual promotes the formation of elementary mathematical concepts in children.
Working with copybooks, students consolidate knowledge about numbers (from 1 to 20), count quantitative and ordinal calculations within the second ten, correlate number with quantity, and vice versa, become familiar with the natural series of numbers, with the place of each number in the series.
They compare numbers and sets of objects, select a given number of objects from a group, and divide sets into subsets. Reinforce the composition of numbers (from 2 to 20), computational techniques, solving problems and examples.
The techniques included in the notebook develop children's logical thinking, emotions, interest in learning, attention, memory, intelligence, promote the development of will, perseverance through problem solving, and form a positive attitude towards learning, interests, and abilities.
The workbook is used as a supplement to basic textbooks and notebooks in mathematics.

Solution: The problem statement states that Faith- winner in skiing competitions, which means she is engaged in the ski section. It is also said in the problem statement that Sonya is not interested in swimming, and she also does not participate in the ski section, which means she goes in the gymnastics section. And by method of elimination we find that Tanya visits swimming section. Answer: Vera is in the ski section, Sonya is in the gymnastics, and Tanya is in swimming.
