Lesson notes for the senior group
Summary of an open lesson on the formation of elementary mathematical concepts in preschoolers in the senior group.
“Comparing objects by size, width, height, thickness and length” (fastening)
Triune task:
Learning objectives: 1. teach children to arrange objects in ascending and descending order by size, width, height, thickness and length;
2. learn to determine the size of objects by eye, check the correctness of tasks by measuring objects: by applying, applying and giving them characteristics;
3. consolidate ordinal counting within 10, connecting numerals with nouns; use adjectives correctly in speech.
Developmental tasks:- develop attention, eye, fine motor skills, thinking, grammatical structure of speech.
Educational tasks:- cultivate the ability to work independently, develop mutual control skills;
To instill a love for Russian folk tales, to cultivate a friendly attitude towards each other.
Equipment:
Demo material:
Easels with magnetic boards, flat images of a fox and a crane, (from the Russian folk tale “The Fox and the Crane”), images of houses; stripes of different widths, cylinders of different thicknesses, a ball, a pointer, 2 pictures based on a fairy tale.
Handout:
Trays with stripes, jars with plasticine balls (nuts), jars with beads, stands for beads.
Activating the dictionary: friendship, log.
Progress of the lesson:
1. Introductory part. Org. Moment. Guys, let's remember the Russian people. fairy tale "The Fox and the Crane". At first, the fox and the crane lived amicably, they went to visit each other. The fox prepared semolina porridge on a plate for the crane; and the crane prepared okroshka for the fox in a jug. But they were not able to try each other’s food, because the dishes with porridge and okroshka turned out to be inconvenient. They were left hungry and angry. And in the end they became friends.
But in our lesson we will try to reconcile them and come up with a continuation of the fairy tale, because... This tale is about the friendship of a fox and a crane. And so that they make peace, you will help me. Ready to help? Then listen.
2. Main part.
1. Working with demo material. "Tracks"
The fox and the crane became friends. After a quarrel, the crane moved away from the fox to another place so that the fox would not find him. But the fox wanted to make friends with him again and went to look for him. She walked and saw high and low houses, to which wide and narrow paths led. The fox wanted to follow the narrowest path, but does not know which of them is the narrowest. Let's help the fox.
Working with handouts.
- Count your tracks (call the 1st child to the board to count)
Lay out the paths from top to bottom from widest to narrowest.
Let's name the width of the tracks (check with the board, I call the 1st child to the board, he lays them out, the children check)
Which path will the fox take?
2. “Houses” - working with demonstration material. The fox followed it and reached the houses.
Count the houses (call to the board)
Let's arrange the houses from lowest to highest.
Name them by height.
And now we will attach a crane to each house. The height of the crane must coincide with the height of the house (checked by the child)
The crane lives in a blue house.
The fox found the crane's house.
3. “Nuts” - work with handouts.
- The fox brought the crane nuts as a gift, but scattered them in front of the house. Let's help the fox collect them from the smallest to the largest and arrange them from left to right. Name their size. Count them. The fox gave all the collected nuts to the crane (check each other), he was happy and gave her tea. Lisa also invited him to visit her.
Physical exercise.
1-2 - everyone get up, 3-4 - squat, 5-6 - turn around,
7-8 - smile,
9-10 - don't yawn,
Take your place.
4. “Logs” - work with demonstration material.
Let's continue the fairy tale.
The crane went to visit the fox and saw a pile of logs on the road. The fox will build a new home from these logs. The logs were thick and thin (let's count). The crane wanted to lay out the logs, but he couldn’t. Let's help the crane arrange the logs in order from left to right from thickest to thinnest. Compare them. Name their thickness.
5. “Beads” - work with handouts.
The crane was carrying beads to the fox, but tripped over these logs and the beads scattered. He had 8 beads, let's count them, are the beads lost (counting).
Let's help you assemble beads from beads from left to right from longest to shortest. State the length of each bead. We helped the crane collect beads and now he can give them to the fox. Lisa was happy. And since then, the fox and the crane have been friends to this day. That's the end of the fairy tale, and whoever listened - well done!
III.Final part. Bottom line.
1. - Tell me guys, about whom did we write a fairy tale?
2. - What is it called?
3. - Did you like the fairy tale?
4. - What did we compare in terms of width? (tracks)
5. - What did we compare in height? (houses)
6. - What were compared in size? (nuts)
7. - What did you compare in terms of thickness? (logs)
8. - What did we compare in length? (beads) 9.- 0 what is this fairy tale? (about friendship)
Well done, I liked the way you worked. The fox and the crane gave you gifts and told you to always be friendly guys, like the fox and the crane.
