Comparison of objects according to one criterion of size. Comparison of objects by shape

Creating a collaborative environment.

The bell rang loudly and class began.

Stand up straight, don’t make any noise, everything is on the desk, look.

Is everything in place, is everything in order: A book, a pen and a notebook.

Every student knows that a diary will be needed.

The sun rose a long time ago,

He looked into our window.

It hurries us to class,

We have math!

New topic

Volume is quantitative characteristic space occupied by a body or substance.

For example, take two vessels: a glass and a sippy cup.

Which container can you pour it into? more water?

How can this be done? (compare in pairs)

Solution: Fill one of the vessels and pour the water into the second vessel. If there is still free space left in the second vessel, it means that the first vessel is smaller in volume than the second, and vice versa.

You compared objects by volume. Vessel volume- this is the space inside the vessel that can be filled with liquid. Compare the volumes of the vessels according to the amount of liquid consumed.

Is it always necessary to transfer liquid to compare volume? -Sometimes you can compare the volumes of blood vessels visually. For example, the volume of a bucket is less than the volume of a barrel.

What objects can be compared by volume?

The property of volume is possessed not only by vessels, but also by other objects not intended for liquid.

You can also measure the volume of a box, because it also has space inside and holds objects. (Demonstrate different boxes. As a measure, you can take cubes and put them in one box, filling it to the brim. Then transfer these cubes to the second box .)

Which box of cubes contained more? Which one is smaller? On what basis did you compare?

Conclusion: if the item is not intended for liquid, then the measure can be small cubes or other objects.

Fizminutka - interactive

Working from the textbook

Determine the volumes of the jug and box.

-P Look at the illustration in the textbook and answer the questions:

How can you fill the space inside the jug? (juice, water, etc.)

How many glasses of water fit in the jug? (8 glasses)

Conclude what is the volume of the jug? (8 glasses)

How can you fill the space inside the box? (cubes)

How many cubes do you need to fill the box? (15 cubes)

What is the volume of the box? (15 cubes)

What are a glass and a cube for of this measurement? (by measurements)

8 glasses; 15 cubes.

Compare the volumes of two vessels. ( Completing the task frontally.) Conversation based on illustrations in the textbook.

a) the volume of bottle A is greater than the volume of bottle B, because A holds 6 bowls of liquid, and B holds 5 bowls;

b) the volume of bucket B is less than the volume of bucket D, because B holds 3 bottles of liquid,

and in G - 4 bottles.

Decide. Complete the task in pairs.

To determine the volume of a figure, students need to count the number of small cubes that make up the figure. If you have any difficulty completing this, you can ask:

How many small cubes fit in the first (second, third) figure?

7 cubes; 6 cubes; 8 cubes.

Try. Practical purpose of this assignment is the development of research skills in children. Complete the task in pairs.

Answer

Options: within 25-30 spoons, depending on the size of the bowl and spoon.

Working in a notebook

Choose a vessel with a larger volume.

IN visually compare the two vessels. Which one has more space inside? Explain your choice and color this vessel with a red pencil.

Count the number of small cubes in each shape.

ABOUT determine the volume of each figure and write the result as a number. Then they must find out whether among the figures there are equal in volume. After completing the task, the children will come to the conclusion that figures of different shapes can have equal volumes.

a) 7 cubes; b) 8 cubes; c) 7 Cubes. Figures a) and c) have equal volume.

Which bucket will hold more water? When completing this task, first-graders must color the vessel whose volume is larger.

Compare the volume of the vessels.

Which of the three containers will require less water to fill and circle it.

students using the "Ladder of Success" in workbook.

Reflection

– What can you say about your work in class?

Think and answer the questions:

The kettle holds 30 bowls of water. What is the volume of the kettle?

The volume of the box is equal to the volume of 20 cubes. How many cubes fit in the box?

Do you think there is a need for a single yardstick to measure volume?

I suggest you entertaining tasks in mathematics to compare objects by size and shape, which I use both in mathematics lessons and in the classroom extracurricular activities“Young mathematician”, Logic” in the first grade.
Purpose of tasks- use as additional material after studying the topic “Comparison of objects”, when conducting oral counting during the lesson, also at the end of the lesson as a reflection.
Entertaining helps to intensify mental activity.
Tasks contribute development of logical thinking, attention, memory, development logical operation- comparison.
The tasks are intended for younger children school age(7-8 years old). Students do them with pleasure.
With the help of these tasks, children learn to compare objects by size (tasks 1-4)

Tasks 5-7 teach you to compare objects by shape.
Task No. 1
Draw a balloon. Draw a blue ball that is bigger balloon. Draw a red ball that is smaller than a balloon.
Task No. 2(comparing items by size)
For example, let Lena come to the board. Are there any girls in our class who are the same height as Lena? And from the boys?
Task No. 3(comparing items by size)

Task No. 5
Students are offered shapes (circles, triangles, squares, pentagons). Arrange the figures in different groups according to form.
Task No. 6(comparing objects by shape)
Students are offered shapes (circles, triangles, squares, pentagons) of different sizes. Select figures of each shape and arrange them in a row in order of increasing size - starting with the smallest and ending with the largest.
Task No. 7(comparing objects by shape)
Students are offered shapes (circles, triangles, squares, pentagons). Color the shapes different colors so that figures of the same shape are colored with a pencil of the same color.

Good afternoon, dear readers! I welcome you to another audio lesson with a text addition to the second part of the “That’s What They Say in America” course, which is intended for beginners. This lesson will help you understand simple words and phrases that are used daily in American speech. In today's audio lesson you will learn how to compare different objects, things and objects in English. Comparison of objects and objects in English

In today's lesson you will learn expressions that can be used to compare different various items and objects in English. You will also learn some words broken down into grammatical categories And popular phrases related to the topic of today's conversational English audio lesson. And right now, read the situational dialogue: radio reporter M. Lerner is talking with his colleagues during a break at work. Journalists compare different things and cities in America:

Howard:What city do you like, Cara? — Which city do you like, Keira?
Cara: New York City is the best. — New York is the best!
Waleed:Why? - Why?
Cara: It's exciting. It's bigger. The buildings are taller. The people are livelier. - He's amazing. Big. The buildings are taller. People are more alive
Waleed: I lived there for several years. I like Washington better that New York. — I lived there for several years. But I like Washington, it's better than New York
Martin: Why do you like Washington better? — Why do you like Washington more?
Waleed: It's slower. It's smaller. - He's slower. It is smaller (smaller).

Watch and listen to a similar audio lesson Description of the city and its districts

So, here you have read examples of using expressions to compare various objects, things, cities and other objects in everyday English conversation. Now listen to how this dialogue sounds in English as a whole, as well as other vocabulary related to the topic of this lesson: /wp-content/uploads/2014/11/russian_english_083.mp3

Follow the recommendations and instructions of the Russian Voice of America radio announcer, Anna Filippova, so as not to disrupt the sequence and logic of learning and to make the process of learning English as simplified as possible. Use the audio recording of the lesson to practice pronunciation and to train your listening comprehension of American English.

Use the table and the grammar help after it to remember the degrees of comparison of adjectives in English, learn nouns, adverbs and other vocabulary with which you can compare different objects, persons, objects and things in English. And after the table, you will see a brief grammar reference and a task for written and oral work Houses.

Grammar help:

Every day, without thinking, we compare various subjects and objects using adjectives in the superlative or comparative degree. For example, when describing a building, we use the adjective “ modern" - "modern" . When comparing it with another building, we use a comparative adjective: “more modern” - “more modern” . If we compare it to several buildings, we use the adjective in superlatives: “the most modern building” - “the most modern building.”

Excellent and comparative degree English adjectives are formed using the suffixes " -er, -est" or the words " more, most" For example:

• cold - colder - the coldest
• beautiful - more beautiful - the most beautiful
• good - better - the best.

Don't forget to do the practical Homework(Homework):

1. Learn the dialogue that started today's lesson and the table with new vocabulary. Act out a similar dialogue.
2. Make up several sentences with the following words: best, worst, oldest, taller, nicer, newer, bigger.
3. Translate to English language and write down the translation in your notebook:

• My briefcase is the oldest
• You make the best coffee
• Miami more modern city than Tampa
• Government buildings make Washington DC the most beautiful city in the United States
• Houses in New York are taller than in Washington
(1 Votes: 1,00 out of 5)

I have 5-6 items on the table, of which 3-4 have same shape. In hands - a token brown and nut. I suggest you compare a token and a nut.

· - Do these items have anything in common? How are they different?

· (Different sizes; the nut is edible, but the token is not; both are round, but the token is flat, and the nut is convex.)

· See if the squirrel has objects that have the same shape as a nut? (Ball, apple, ball.)

· These objects are said to be spherical in shape. (Children repeat in chorus.) Are there spherical objects in our class?

Lesson summary.

Guys, now we know what it is geometric shapes. Our lesson is over. Well done to you all today.

Topic: “Sounds in the Zoo” Game “1,2,3,4.5 the bunny went for a walk”

Goals:

• Strengthen children's ability to divide words into syllables;
• Consolidation of words in the Tatar language by lexical topic: "Animals";
• Develop attention, memory, verbal- logical thinking, imagination, fine motor skills;
• Develop the ability to understand the task at hand;
• Foster respect and love for animals;
• To consolidate children's knowledge about domestic and wild animals and their cubs;

Progress of the lesson:

Guys, guess the riddle:

There is a good kind house,
Animals settled in it.
Wolves, zebras and monkeys,
Both big and small. (Zoo)

Today we will mentally go on an excursion to the zoo.

Let's take binoculars and everything we need with us. (We imitate gathering at the zoo). Are you ready?

One, two, three, four, five
Let's go for a walk to the zoo.

Let's go, jump over the stream. Here we are at the zoo.

Let's look through binoculars and see who's here.

Children take turns answering who sees what. (“Monkeys are frolicking”, etc.)

Let's listen to the sounds of the zoo.

Children take turns answering who hears what. (“I hear the birds singing”, etc.)

Illustrations of several animals are displayed on the board.

Compilation descriptive story.

Guys, look, not all animals are here. Apparently the animals decided to play hide and seek with us. Let us compose a descriptive story based on the picture using a diagram, and if the animal is guessed, it will appear on the easel. The diagram is displayed.

The child chooses an illustration with an animal, but does not show it to other children, and describes it according to the teacher’s plan. Children compose 5-6 stories.

Children are asked to name the animals in Tatar.

Physical exercise.

Now let's rest a little.

Children walk in a circle and depict how animals move: fox, hare, wolf, bear, deer.

Game: “Who talks like this.”

Do you know how animals talk?

Ball game.

• The cow...moos.
• The horse... neighs.
• The goat...bleats.
• The pig... grunts.
• The dog...barks.
• The cat...meows.
• The tiger...growls.
• The wolf...howls.
• The bear...roars.
• The hedgehog...sniffles.

Game “Which one? Which?"

Guys, let's imagine that you are now not children, but animals, and everyone will tell about themselves. One, two, three times, spin around yourself and turn into a beast.

• (Each child names three words of definition)
• I am a bear - shaggy, club-footed, strong, clumsy, big;
• I am a fox - cunning, red, fluffy, beautiful, long-tailed, sharp-toothed;
• I am a wolf - angry, hungry, predatory, gray, toothy.
• I am a hare - cowardly, long-eared, herbivorous, short-tailed, timid, fleet-footed;
• I am a hedgehog - prickly, agile, small, short-legged, sharp-nosed.
• I am a squirrel - dexterous, agile, jumping, thrifty, fast, nimble, playful.
• I am an elk - horned, big, long-legged, herbivore.
• I am a lynx - cunning, predatory, dexterous, strong, jumping, fast.
• I am a cat - soft, affectionate, playful, domestic. I am a goat - horned, butted, herbivorous, playful.

They turn back into children.

Game “Divide into syllables” ( wonderful pouch)

Children, let's divide the names of animals into syllables and place them in houses.

Children take turns taking an animal figurine out of the bag. The name of the animal is divided into syllables.

Guys, our tour is coming to an end. We had a hard time looking at the animals, but we also found their cubs. And now it’s time for us to return to kindergarten.

One, two, three, four, five
We're going to kindergarten again.

Bottom line.

Did you enjoy the zoo?

What did you like most?

Topic: Counting from 1 to 10. Exercise “Comparing objects”

Goals:

Exercise children in quantitative and ordinal counting within 10.
Strengthen the ability to recognize and name numbers from 1 to 10.
Clarify the name of geometric shapes (circle, square, rectangle, triangle, oval).
Continue to develop in children an understanding of addition, subtraction, and the signs “+”, “-”, “=”.
Develop logical thinking, memory, attention.

Progress of the lesson

Now we have a lesson on the basics of counting. Today we will remember what we did in this academic year, and at the same time we’ll take a trip into a fairy tale. But first, we'll do the math. We will count these Christmas trees on the board (there are 10 Christmas trees on the board) (children count in unison from 1 to 10).

Now let’s count the Christmas trees from 10 to 1. And now on our board you will see numbers. We will also count backwards, but not from 10 to 1, but from the number you see on the board (children count backwards from the number 6, 8, 4, 9).

A picture with the heroes of the fairy tale “Kolobok” appears on the board. Teacher: “What fairy tale did these animals come to us from (answer). How many animals are there on the board? Who did Kolobok meet first in the forest? Who's second? What kind of a fox (wolf) was there? Name the hero who stands to the left of the fox (answer), to the right of the hare (answer).

The heroes have prepared for you math problems. Let's do them. If we do them correctly, there will be a surprise at the end.

1st task The bunny has prepared for you.

A picture appears on the board showing 9 cows and 8 piglets. “The bunny asks you to count the animals and circle the number below that shows the number of animals on the board” (the teacher calls 2 children to the board to complete the task).

2nd task from the bear

(on the board there are numbers from 1 to 10 in 3 rows. In each row one number is missing). “The bear wants to test how attentive you are. You need to look carefully at the numbers and say which number is missing (children name the missing number and name between which numbers it should appear. The teacher writes the numbers on the board).

E task - wolf.

Rectangles appear on the board, with a number written above each of them. The teacher calls the children to the board and asks them to draw as many circles in each rectangle as the number above shows.

The task is a fox.

Lisa invites you to solve the examples. Examples of addition and subtraction are written on the board in geometric shapes (circles). The teacher calls the children to the board and invites them to solve these examples (draw the required number of circles). “And the fox also wants to know if you know the names of geometric shapes. An image of a cat made of geometric shapes appears on the board. The teacher asks to name the figures that make up the cat and answer the questions: How many paws does the cat have? How many eyes? How many ears? Heads? Etc.

Physical education minute.

Smile at the one on the right.
Smile at the one on the left.
Give your hand to the one on the right.
Give the one on the left your hand.
Now you walk in a circle,

and walk together as friends.
Wink to the one on the right.
Wink to the one on the left.
Hug the one on the right.
Hug the one on the left.
Well, the game is over,
Time for math!
There are ideas and tasks here,
Games, jokes - everything is for you!
We wish everyone good luck -
For work, in good hour!

Good afternoon, guys.

Look who's visiting us today.

Owl flew to visit us.

That's right, Owl - a wise little head - came to visit us. She flew to us today for a reason, she wants to introduce us to the world mathematicians, now the owl will turn you into smart people and smart girls, and we can go into the world with you mathematicians(owl touches with a magic wand to children). Smart guys, sit down at those tables, and smart guys at these tables.

2. Main part

2.1 Exercise in counting items up to 5

Look, there is something under a napkin on your tables. Want to know what's there? I can't wait to find out what's there too. So let's look under the napkin. What lies here?

Under the smarties' napkin there are cars, and under the smarties' blanket there are dolls.

Yes, smart people have cars under their napkins, and smart girls have dolls. Smart guys, count how many cars you have on your table, and now smart guys, count how many dolls you have on your table.

How many cars are on the table?

One, two, three, four, five – five cars in total.

That's right, smart guys.

How many dolls are there on the table?

One, two, three, four, five - five dolls in total.

That's right, you guys are so smart, you're all so smart and smart and smart.

Smart guys and girls, our dolls are going to go visit their friend the doll Katya, let's see if all the dolls have enough cars. Did everyone have enough cars?

There were enough cars for all the dolls.

2.2 Exercise in comparison of groups of objects by quantity

That's right, smart guys and smart guys, all the dolls had enough cars, but one car was left extra, so why more than 5 cars or 4 dolls?

5 cars are more than 4 dolls.

That's right, 5 cars are more than 4 dolls. What is less than 4 dolls or 5 cars?

4 dolls are less than 5 cars.

Well done, of course 4 dolls are less than 5 cars.

2.3 Group equation items by quantity

Smart guys, how can we make sure that there is an equal number of cars and dolls? Smart guy Alexander is called, show us the first way to make sure that there is an equal number of cars and dolls (adds one car). How many dolls and cars are there?

One, two, three, four, five - five dolls in total. One, two, three, four, five - five cars in total. There are now 5 dolls and 5 cars.

That's right, well done, 5 each (I remove one doll). On the smart side, smart girl Polina is called in, show us how else we can make it so that there is an equal number of cars and dolls.

I'm cleaning one car.

Right. How many dolls and cars are there?

Let's count dolls: One, two, three, four - four dolls in total. Now let's count how many typewriters: One, two, three, four - four cars. Now there are 4 dolls, 4 cars.

Well done, Polina, 4 dolls and 4 cars. You thought so well and compared, what great fellows you are, and smart people, and smart girls.

2.4 Completing tasks with a handout material: comparison and alignment of geometric shapes according to quantity

Owl, the wise little head, has a task for you, now I’ll do it for you I'll read it: “Smart guys and girls, you should find out what you have on your tables more, circles or squares. You have cards on your tables, place circles on the top strip of cards, and squares on the bottom strip. What are there more or less circles or squares on the card?

One, two, three, four - four circles in total. One, two, three, four, five - five squares in total. There are more squares than circles.

Well done guys and girls there are more squares than circles, why less squares or circles?

That's right, there are fewer circles than squares.

I like how well you all complete the tasks, you know geometric shapes so well and you are so capable compare what more, and why less, how smart you all are,

the owl and I are very pleased with you.

2.5 Game exercise with a competitive element “Arrange the pieces.”

Now let's put everything aside. The wise little owl wants to play a very funny game with you game: Clever guys and girls, you must collect a crop of geometric ones for Sovushka figures: from cubes and balls, I will be very grateful to you. The smart team will be harvesting on this side of the carpet, and the smart team will be on that side, you must collect the cubes in one basket and the balls in the other, let's start. What a great fellow, everyone collected the harvest for the wise little owl. Now let's let's compare, whether our geometric harvest is collected correctly.

The harvest of smart girls will be checked by clever Yuri, and the harvest of smart girls will be checked by clever Arina.

Well, well, well, a ball fell into the basket with cubes, what should you do with it?

Place it in a basket with balls.

That's right guys. Clever and clever, you are very good at harvesting geometric crops, and how well do you know geometric shapes. Even though there were small mistakes, you are very well done.

2.6 Completing tasks with a handout material: comparison"ice paths" on two grounds quantities(length and width)

Smart guys and girls, what time of year is it now?

That's right, what do you like to play in winter?

Sledding, playing in the snow, riding on icy paths.

There are so many interesting things you can do in winter, look, the wise little owl has prepared icy paths for you, compare them which one is longer and which one is shorter. Show me all the long path, and now show me the short path, well done, now I want to see the wide path, and now the narrow one. That's right, what can you call a long and wide path?

Big path.

Well done, big, what about a narrow and short path?

Small path.

That's right small. And now, you smart guys, you have to roll the snowball along the big path, and the smart guys along the small path. How wonderful it is for you to roll snowballs along icy paths. Well done guys.

3. End classes

The wise little owl and I really liked today that you were all very friendly, smart and did a good job with all the tasks. You are real smart people and smart people, well done everyone.

It's time for the wise little owl to fly to her country. Therefore, she will now turn you again from smart guys and smart girls into boys and girls. Let's all say goodbye to the owl.

Guys, what do you want from classes Did you remember and like it the most? Girls, do you think boys can be called smart? Boys, can girls be called smart? Did you enjoy being smart and clever?
