IV . Working on the lesson topic
1. Creative task. The class is divided into groups (2-4 people). I distribute to each group an A4 sheet of paper and a standard safety instruction for students in a computer class, divided into semantic parts.
Teacher. Guys, we repeat safety rules at least twice a year. And you all know them well. Therefore, we will combine your creative abilities with repetition of the rules.
You have a card on your desk with several safety rules. Your task is to turn them into poetry. 10 minutes to work. Upon completion, each group will defend their work. One student reads the rules written in the instructions, and the second reads your poems.
2. Practical work in a programme MS Word according to the algorithm.
Guys, now we will work on maintaining a uniform spelling regime in our school. Your task is to execute the algorithm and obtain the final printed product.
V . Reflection. Summing up the lesson
To summarize the lesson, use the “Plus-Minus-Interesting” exercise. This exercise is performed orally. First, students answer what they liked in the lesson, what caused positive emotions, what, in the student’s opinion, could be useful for him to achieve some goals (“P” - “plus”). Next, it is voiced what was not liked in the lesson, seemed boring, caused hostility, remained incomprehensible, or information that, in the student’s opinion, turned out to be unnecessary for him, useless from the point of view of solving life situations(“M” - “minus”). And we complete the reflection with facts that aroused the students’ interest (“I” - “interesting”)
This exercise allows the teacher to look at the lesson through the eyes of the students and analyze it in terms of value for each student.

During the classes:
1. Organizational moment.
New lesson!
New knowledge!
New discoveries!
2. Setting goals and objectives for the lesson. Motivation for learning activities.
Teacher: Guys, from the epigraph to our lesson you already guessed that today we will have some kind of new lesson, we will gain new knowledge, make new discoveries, and everything new is always something interesting.
Today you went to class and already knew its name - COMPUTER SCIENCE.
You came to the computer science classroom for the first time. It is very similar to a regular school classroom, but the difference is immediately obvious: there is a computer on each table. From today you will learn to work with it. I would like to believe that the computer will become your good assistant.
And first we'll talk aboutrules of behavior in the computer class.
For an assistant to be kind and beautiful, you need to treat him carefully. The computer does not tolerate dirt. Dust, which always happens in an uncleaned classroom, settles on the surface of the machine, penetrates inside and disables precision electromechanical devices and damages electronic circuits.
Therefore, the first requirement that must be observed in the computer science classroom is cleanliness. (On each table there is a memo with the rules of behavior in the computer class).
You cannot come in dirty shoes and clothes. Clean your jackets and briefcases before entering class.
Didn't have time to have lunch during the break before your computer science lesson? It’s better to be patient, but don’t bring bread, nuts, sweets, or seeds with you. Crumbs will damage your computer more than dust. If they get between the keys, they are not so easy to remove.
Chewing gum, no matter how tasty it may seem to you, is strictly prohibited for anyone sitting near a computer.
As you head to computer science class, take a look at your hands. With these hands you will now type messages to the machine. And if your nails are dirty, if your fingers are dirty and greasy, then your computer keys will be just as dirty. But both your teachers and your comrades from another class will work at this keyboard! Think about them, think about the fact that your dirty hands will get dirty, old and simply disable school computers.
The second most important requirement in a computer science classroom is discipline. No keys (even after you learn what they mean!) can be pressed without the teacher's permission. Of course, if you press the key, there will be no explosion or fire. But if the machine is prepared for a lesson, and you, without notifying the teacher, decide to play around with the keyboard, then most likely the prepared material will be spoiled.
Special warning: Never press the computer's power off button. electrical network. This may cause your computer to malfunction. It will take many hours to recover.
Computers operate from an electrical network, the voltage of which is dangerous to life. Be careful! Do not touch the wires that are connected to the computer.
When pressing the keys on the keyboard, do not use much force. The computer will understand you even with the gentlest touch. Remember that drumming on your keyboard will quickly damage it. You should also treat your mouse and other devices connected to your computer “gently.”
Do not touch the monitor screen even with clean fingers - marks will still remain on it.
The rules of behavior in the computer science classroom are not too complicated. But they must be observed very strictly. By being attentive to your cars, you will learn a lot and see a lot of interesting things on the screens.
Who knows what computer science is? (Children's answers).
To make your knowledge more accurate, look at the board (slide 1) and listen to the poem:
I will teach you computer science,
And we will become friends with you.
In the vast world of information
You can’t live without machine guns,
And a machine gun is a device
What man has created to help.
I will teach you gradually,
How to store information
How to process, transmit,
I will teach you to reason.
The computer will become best friend,
He is indispensable in learning,
Like a book, pen and notebook,
You will need it.
(INFORMATION SCIENCE=INFORMATION+AUTOMATION)
-Can anyone guess what we will talk about today in our first computer science lesson? (Children's statements).
-That’s right, the key word in our lesson today will be the word “information.” And what exactly we will learn related to this concept, read in the textbook - p.7.
(Target:
Understand that we live in a world of information that we study using our senses. Learn to analyze signals perceived through the senses.)
3. Updating knowledge.
Guys, how do you explain what “information” is? (News, information, when someone speaks, watch TV, read a book, newspaper, etc.)
When discussing this issue, draw students’ attention to the fact that during conversations people convey information, some news. Lead to the conclusion that information is information about the world around us .
Open explanatory dictionaries (Ozhegova) and read What does this word mean:
Information – this is information about the surrounding world and the processes and phenomena occurring in it, perceived by a person or a special technical device.
What do you guys think, can a person live without information?
In fact, the concept of “information” is somewhat broader than we defined it, and involves the sensations and perception of the surrounding world by each person with the help of the brain and sensory organs - the organs of vision, hearing, smell, taste and touch. In other words, information is also the freshness of the rain, and the sound of the wind, and the warmth of the sand heated by the sun, and the joy of seeing a rainbow in the sky... All this is information.
To understand how people and information are connected, let’s do a littlestudy.
During all tasks, you must carefully monitor what is happening and what you are doing. This will allow you to draw certain conclusions.
Exercise 1
– Guys, try to talk about objects without touching them(on the teacher’s desk: ball, candy, clock...)
Task 2
– Close your eyes. You don’t see, you don’t hear, you don’t touch with your hands. Tell us about the item(teacher sprays perfume, air freshener...)
– Which authority helped you obtain the information?
Task 3
– Close your eyes. Tell us about an item without seeing it, but you can try it(students try: lemon, sugar, candy...)
– Which body helped you obtain the information?
Task 4
– Close your eyes. You do not see. What sounds did you hear?(applause, the door creaked...)
– Which body helped you obtain the information?
Task 5
– Close your eyes. You don't see or hear, but you can touch it with your hands. Tell us about the subject.(In my hands there is a package, a soft toy,
chocolate foil
…)
– Which body helped you obtain the information?
Teacher:
– Well done! We completed all tasks well.
How did we get information?
Our senses help us receive information.
– How many sense organs does a person have?(5)
– What are these sense organs?(Eyes, ears, nose, tongue, skin).
- What conclusion have we come to after completing all the tasks?
– A person receives information using 5 senses: eyes, ears, nose, tongue, skin.
4. Primary assimilation of the material: (work on presentations and applications).
Teacher. Remember, with the help of which sense organ we receivedinformation about the objects located on the table? That's right, weused vision.Vision helps to distinguish the colors of objects, their sizes, shapes, recognize whether they are far or close, moving or stationary. Thanks to vision, we read books, watch TV shows, and admire the beauty of nature. Eyes are like windows to the world. Take care of your eyesight. (Slide).
Teacher . Give examples when a person receives visualinformation. (We read a magazine, look at each other, look draw a graph or drawing,
watching TV, looking at a picture
in the museum.)
.
- Do you know that a person can determine distance by eye: look at the diagram cards on your desks(Appendix 2)
50 steps – eyes and mouth
300 steps - face
1.5 km – burning match at night
6 km – factory pipes
8 km – firelight at night
– What organ allowed us to smell?(Nose)Slide shown
– Give examples when a person receives information through the nose.(Students' answers)
– Many pleasant smells bring us joy: the smell of flowers, the smell of a coniferous forest. Some smells seem to warn of danger, for example, a gas leak from gas stove or that the food is spoiled and cannot be eaten! Conversely, the pleasant smell of food stimulates appetite. When you have a runny nose, you have trouble smelling. We must protect ourselves from colds!
Teacher.
Which sense organ helps us determine the taste of food or drink?That's right, it's a language.Information we receive through languagewhen we eat or drink something, it is called taste.A slide is shown.
What taste can we taste?(Sour, bitter, tasteless, sweet, minty, salty, spicy.)
– There are special taste buds on the tongue. Thanks to them, a person distinguishes the taste of food. A person eats tasty food with appetite. Sometimes we know by taste that food is spoiled and cannot be eaten. Food that is too hot burns the tongue and we hardly feel its taste. The food should not be very hot!
Slide shown
Which organ allowed us to identify sounds?(Ears).
– With the help of ears a person hears speech, music, noise.Slide shown
– Give examples when a person receives information using his ears.(Students' answers)
– It is especially important for us to hear other people's speech. After all, with the help of words we convey our thoughts and knowledge to each other. We also need the wonderful sounds of nature and music. These sounds are part of the beauty that surrounds us. Noise can not only disturb, but also cause useful information– for example, the noise of the engine tells us that a car is approaching, and we need to be more careful. Remember that loud noise, harsh sounds, loud music damage your hearing and have a bad effect on the entire body. Rest in silence often.
Hearing range of the human ear: chart cards (Appendix 3)
Noise of a moving train – up to 10 km
Shot – up to 5 km
Car signal – up to 3 km
Dog barking – up to 2 km
Human scream – up to 1.5 km
Vehicle movement on the highway – up to 1.5 km
Vehicle movement on a dirt road – up to 500 m
Spoken speech – up to 200 m
Cough – up to 50 m
Steps – up to 20 m
– Which organ allowed us to determine whether an object is smooth or rough?(Leather)
– With the help of the skin, a person learns what an object feels like - warm or cold, smooth or rough, soft or hard. Even with your eyes closed or in the dark, you can touch information about the size and shape of an object.
– Skin is an organ of touch. Try not to injure the skin, avoid burns and frostbite!
5. Awareness and comprehension of educational information.
a) Physical education minute
– Now let’s rest a little and check whether you listened and watched carefully, let’s play a game: I name the word, and you determine what type of information it can be attributed to. If the information is visual, we close our eyes; if it is auditory, we cover our ears with our palms; if we receive the information in the form of smell, we close our nose; if we taste it, we cover our mouth; if we recognize it with our skin, we clap our hands.
So let's start, be careful:
Ringing, hot, sweet, music, bright, prickly, hot, wet, bitter, green, rough, radio, sticky, high, gasoline, dark, frost.
Well done, you are good at identifying types of information.
b) Completing tasks in the workbook pp. 3-4, according to options in mutual verification mode.
6. Primary consolidation of the studied material
Consolidation of the studied material is carried out in a playful way.
Task 1. Information lotto. Match. (Appendix 4). Work in pairs. The teacher explains the task: toWhat senses allow us to discern information? Match.Cards from Table 2 (pictures with sensory organs) must be laid out in Table 1 (words) to establish a correspondence.
(Table 1) (Table 2) (pictures of sensory organs)
(cards from table 2 are placed on the words of table 1 of the picturesWhoa up) Whenthe task is completed, the teacher gives a test card with correct location pictures and asks students to check the completed task, then together they sort out mistakes if they were made.
7. Information about homework, instructions for its implementation.
Analyze the material in the textbook pp. 9-11, retell in your own words the material in the “Main” section; p.5 – in your notebook, write down the meaning of the word “information” from the dictionary.
8. Reflection.
a) -- Let's go back to the beginning of the lesson, remember what we were supposed to understand and learn.Nature has endowed man with five senses so that he can perceive information. different types.
To make a decision, a person needs several senses: eyes, ears, tongue, skin, nose.
Visual, sound and olfactory information can be obtained without touching the object, and tactile and gustatory information can be obtained by touching the object with your hands or tongue.
Often, to make a decision, a person needs different types of information, perceived through different senses.
"Let's discuss"
What senses does a person have to perceive information?
Why do humans need five senses?
What is the information received through the eyes, ears, nose, skin and tongue called?
What information can be obtained without touching the object?
Why does a person need information?
Reception "Continue the sentence":
I found out….
I understand…
I discovered...
I never thought that..
It was interesting to me…
I don't really understand...
I haven't quite figured it out yet...
b) Watching a video“Ways of obtaining information” as preparation for the material of the next lesson (Appendix 5).

During the classes
Organizing time. Greetings.
The bell has rung!
Called me to class!
We will discuss
And help each other.
The topic of the lesson is not written on the board. The teacher asks the students to guess the riddle.
The answer is the topic of the lesson.
What a miracle unit
Can do everything -
Sing, play, read, count,
To become your best friend?
Answer: Computer.
Slide 4
Well done! You have completed the first task. The topic of our lesson: “Computer”.
Now let's try to remember where the computer is used and how it helps people.
During the dialogue, the students’ answers are analyzed and summarized, their attention is focused on the fact that today we see computers in banks (primarily for performing complex calculations), at train stations (to learn information about train schedules and ticket prices), in libraries, in hospitals, schools, etc. Teacher.
Guys, do you know when they first started talking about creating computer technology?
It all started with the idea of teaching a machine to count or at least add multi-digit integers. Around 1500, the great figure of the Enlightenment, Leonardo da Vinci, developed a sketch of a 13-bit adding device, which was the first attempt to solve this problem that has come down to us. The first operating summing machine was built in 1642 by Blaise Pascal, a famous French physicist, mathematician, and engineer. His 8-bit machine has survived to this day.
In October 1945, the first ENIAC computer was created in the United States. The first generation computers used vacuum tubes. Thus, in 1952, IBM released the first industrial computer, the IBM-701, containing 4,000 vacuum tubes and 12,000 germanium diodes. One computer of this type occupied an area of about 30 square meters. meters, consumed a lot of electricity, had low reliability. Troubleshooting took 3-5 days.
The highest achievement of domestic computer technology created by the team of S.A. Lebedev was responsible for the development in 1966 of the BESM-6 semiconductor computer with a productivity of 1 million operations per second.
See what the first computers looked like
Currently, computers can be classified into the following types
Today we will focus on studying in more detail personal computers. PCs are the most popular and widely used computers. Despite their small size, they have absorbed all the features of a computer and fully reflect its architecture and construction principles. In the future, when considering hardware and software We will talk only about personal computers.
How do PCs differ from each other?
Desktop PCs
The most common are desktop PCs, which allow you to easily change the configuration (external outline, as well as the relative position of objects or their parts)
Laptop computers
Convenient to use, have computer communication facilities. The system unit, monitor and keyboard of laptop PCs are placed in one case: the system unit is located under the keyboard, and the monitor is built into the lid.
Pocket models
are called “smart” notebooks, because they allow you to store operational data and get quick access to them.
Physical education session (musical accompaniment)
Slide 16
Why do you think a computer is needed? (students’ reasoning).
Now let's check how well you know your computer.
What does a computer consist of? There is a sheet of paper with a task on the table in front of you. It shows a computer. In the empty cells, write the names of the main computer devices. (Appendix 1) 3-4 min. Don't worry if you don't know about a particular device. We'll check everything now.
Let's look at each device separately.
System unit, sound speakers.
The system unit is the main device of the computer. The system unit contains all electronic stuffing computer, its “brain”. The main elements of the system unit are the processor (executes programs consisting of commands) and memory (stores data and programs).
Speakers: These devices are used by the computer to reproduce sound.
A computer monitor is a device for displaying information output from a computer. The monitor is similar to a TV. A person receives several types of visual information from it: text, graphic, video. The monitor is called an output device.
Now guess the riddle and think about what device we are talking about.
Mystery!
Even the mother of this mouse
Can safely pick it up.
She has buttons on the back
To type programs.
Computer mouse
A mouse is a device for entering information into a computer. A mouse is a small box with two or three keys. It is easy to hold in your hand. Together with a wire for connecting to a computer, this device really resembles a mouse with a tail.
Keyboard is a device for entering data into a computer. Using the keyboard, text information and commands are entered into the computer. A computer keyboard is a close relative of a typewriter keyboard, only it has more keys. The keyboard has the following keys: alphanumeric, function, control keys and additional keyboard keys.
Slide 23
It's time to solve the crossword puzzle that is on your desk. The same crossword puzzle is depicted on the interactive board. (Appendix 2). Students write down their answers in their crossword puzzles. The teacher calls one student at a time to the interactive board to write down the correct answers. The teacher helps.
Teacher
So, let's summarize our lesson.
Today we tried to answer the questions:
How does a computer help people? Where is it used?
We got acquainted with the history of the creation of computer technology;
classification of computers;
got acquainted with the computer structure; solved a crossword puzzle.
And they answered the main question:
Why do we need a computer today?
Grades for the lesson and homework are announced.
Homework.
Come up with your own funny story about a computer or one device.
You did a good job today. Thank you for the lesson.
Well done!

1. Organizational moment.
Greetings from teachers.
Stretch out your hands
And let your rays come to me,
I will collect your rays
And I'll hold you to my heart,
And then we will succeed.
Report the topic of the lesson and the form of work.
The lesson consists of 2 parts:
Part 1 of the lesson - primary school teacher.
Part 2 of the lesson - computer science teacher.
(The class is divided into 2 groups.)
Part 1 of the lesson.
Work from textbooks (pp. 8-11)
Discussion on questions:
Computers are all around us.
How do you think?
- What has changed in people's lives with the advent of the computer?
- Workers in what professions use computers today?
- What new professions appeared with the invention of the computer?
Computer at school.
How do you think?
- Where can you see computers at school?
- Who are they used for and by whom?
Rules of conduct in the computer class.
You came to the computer science classroom for the first time. It is very similar to a regular school classroom, but the difference is immediately obvious: there is a computer on each table. From today you will learn to work with it. I would like to believe that the computer will become your good assistant.
For an assistant to be kind and beautiful, you need to treat him carefully.
Look at the pictures.
- What did the guys in them do wrong?
- What else can’t you do in a computer class?
- Explain all the prohibitions, think about what their violation could lead to.
- You cannot enter the computer lab without the teacher's permission.
- You are not allowed to enter the computer lab during outerwear, hats, dirty shoes.
The computer does not tolerate dirt. Dust settles on the surface of the machine, penetrates inside and disables precision electromechanical devices and damages electronic circuits.
Therefore, the first requirement that must be observed in the computer science classroom is cleanliness.
3. You cannot bring food or drinks into class.
- Didn't have time to have lunch during the break before your computer science lesson? It’s better to be patient, but don’t bring bread, nuts, sweets, or seeds with you. Crumbs will damage your computer more than dust. If they get between the keys, they are not so easy to remove.
- As you head to computer science class, take a look at your hands. With these hands you will now type messages to the machine. And if your feet are dirty, if your fingers are dirty and greasy, then the keys of your computer will be just as dirty. But both your teachers and students from other classes will work at this keyboard! Think about them, think about the fact that your dirty hands will get dirty, old and simply disable school computers.
- Chewing gum, no matter how tasty it may seem to you, is strictly prohibited for anyone sitting near a computer.
The second most important requirement in a computer science classroom is discipline. No keys (even after you learn what they mean!) can be pressed without the teacher's permission. Of course, if you press the key, there will be no explosion or fire. But if the machine is prepared for a lesson, and you, without notifying the teacher, decide to play around with the keyboard, then most likely the prepared material will be spoiled.
4.You are only allowed to work on the computer specified by the teacher.
5.You cannot turn on and off the computer and other devices without the teacher’s permission.
Special warning: Never press the power button to disconnect your computer. This may cause your computer to malfunction. It will take many hours to recover.
6.Do not touch cords, sockets, or wires.
Computers operate from an electrical network, the voltage of which is dangerous to life. Be careful! Do not touch the wires that are connected to the computer.
7.You cannot place any objects on the system unit, display (monitor), or keyboard.
When pressing the keys on the keyboard, do not use much force. The computer will understand you even with the gentlest touch. Remember that drumming on your keyboard will quickly damage it. You also need to treat the mouse and other devices connected to the computer “gently”.
8.Do not touch the monitor screen even with clean fingers - marks will still remain on it.
9.Do not use mobile phones(it's better to turn them off completely)
The rules of behavior in the computer science classroom are not too complicated. But they must be observed very strictly. By being attentive to your cars, you will learn a lot and see a lot of interesting things on the screens.
Why can't you break the rules?
Well, now let's see how you learned them?
