Comfortable home theater - overhead projector and motorized screen. Mounting the projector to the ceiling: views, installation instructions, tips

Have you bought a projector at home to watch new movies with your family? Is there a need to equip the school class with new equipment? Do you want to install a powerful projector in the auditorium for presentations? Wonderful! But here it turns out that it’s not enough just to choose and buy a projector, for comfortable viewing it is necessary to install it correctly, and along with the difficult choice of the projector itself, the task arises of choosing the right bracket for it in accordance with the characteristics, installation location and tasks performed.

But what are the brackets for projectors and how they differ from each other, we will consider.

Installation location

The choice of a possible location for the projector is determined by the configuration of the particular room in which it will be installed, the screen size and the characteristics of the device already purchased. That is, the parameters of the projector set a small field of options, and from them a possible place is selected depending on the geometry of the room, and then, based on this, the appropriate type of fastening is already determined. Sometimes it happens the other way around - a specific installation location is decisive and then a projector model and screen size are selected for it (for it). Thus, the combination of installation location, projector model, and bracket type is constant, and changing one is likely to change the others.

If the projector has already been purchased, then for it correct installation need to know a few specifications the device itself. The first is the projection distance (projection ratio). It is always indicated in the characteristics of the device and shows what distance is required to the screen at the selected frame size. The user manual usually provides a table of available optimal image sizes depending on the distance. For most projectors, the projection ratio can be changed within certain limits using optical or digital zoom, and this allows you to install the device a little further and closer, or vice versa, without moving the projector, change the image scale. (It should be remembered that digital correction, unlike optical correction, reduces the sharpness of the image).

If the user manual is lost or incomprehensible, then most projector manufacturers provide visual calculator programs with which you can find out the distance to the screen at a given scale.

The second parameter that you need to know is the offset, it shows the departure (shift) of the projection along the vertical relative to the lens (for a desktop installation - up, for a ceiling installation - down).

Next, we determine the nuances of the room, somehow: from which side of the screen the installation is supposed to be (the image is fed to an opaque screen from the side of the viewer or into the light from reverse side on the rear projection screen), what type of ceiling is in the room (concrete, frame, stretch, etc.); are there any obstacles in the path of the rays (chandeliers, air conditioners, ceiling height transitions); whether the appliance is likely to fall due to pets or children; whether the fact is taken into account when choosing the place of installation high heat most popular projector models?

If, due to the nature of the room, the projector cannot be placed perpendicular to the screen and you plan to install it higher (lower) and / or to the right (left) of the center, then you should use the vertical or horizontal frame geometry correction function that most modern models and which makes it possible to correct keystone distortions on the screen by changing the position of its four corners.

If none of the calculated installation points fit into the design of the room, and others go beyond the capabilities of the projector, for example, too close as in interactive whiteboards or too far as in conference rooms, then to change the projection distance, you will have to purchase an additional long throw or short throw lens.

Thus, the installation location will unambiguously determine the installation surface (ceiling, wall, shelf) and, accordingly, the type of bracket.

Bracket types

One of popular types mounts. used as stationary version in case the screen space is permanent and the projector itself is not transferred for presentations in different places. It is also necessary to exclude the impact of small children and pets both on the projector body itself and on the cords and cables leading to it, however, an adult can step on or stumble over the wire and cause the device to fall.

The same fixed option, as in the previous case, is used when, due to the presence of a chandelier, point light sources, a multi-level or low ceiling, or the artistic design of the latter, the projector has to be fixed to the wall. Suitable for wall mounting solid wood, concrete or concrete blocks. Since the optical axis will be shifted, and quite significantly, the projector model must be able to compensate for keystone distortion.

elevators

Motorized projector lifts are used for hidden installation apparatus in a false ceiling. Most often used in office, administrative and industrial premises where there is sufficient space or a niche for the installation of the movement (although ultra-thin models with a height of 30-40 cm are also produced). For home use usually such a mechanism is used to save design style premises. The lifting mechanism can be cable or worm, etc.

The most common type of attachment (position), as it will allow you to use any comfortable furniture as substitutes. This option provides very quick installation and the ability to move along with the screen to another point in the room for quick search best quality Images. This option may be needed, among other things, for a quick change of position in different time days, if sunlight enters the room or draft from open window, air conditioner or fan shake the screen. Also, this installation option is needed if the projector itself is used as a mobile projector for presentations of business projects in different rooms.

Selection criteria for price.

As the cost of the brackets increases, the weight of the projectors that they can support increases, additional adjustments appear in the form of angles of inclination, rotation (or both at once), the rod becomes adjustable, and its length varies more and more, the bracket itself becomes universal with the possibility of fastening as on the wall, and on the ceiling, the quality of workmanship and assembly increases.

Bracket connection

Unlike TV mounts with standardized sizes between mounting holes (VESA), projector mounts due to unique combination attachment points in each model are designed either for a specific bracket manufactured by the same manufacturer, or for a universal one, that is, one in which the legs of the platform (the so-called "spider") for connecting to the device have an infinite number of possible positions and attachment points. No matter how unique a projector on a universal mount is, after shifts and turns, there is sure to be an appropriate position for mounting points. For this, sometimes projector manufacturers make possible attachment points redundant, that is, some of them (one or two) simply remain unused. The mobility of the legs is also needed in order to correctly balance the device and its center of gravity relative to the bracket. It is also necessary to keep in mind that the projector lens is usually located closer to the side wall of the case, and the center of symmetry of the bracket and the optical axis (lens) will not match.
The connection itself is not difficult - all the necessary fittings (screws, screws, dowels) are included with the projector. In the case of using a universal mount, it is only necessary to center the device so that none of the corners outweigh, and only then carefully fix all the screws, turning them all the way.

P.S.

In addition to installing the projector, it is also necessary to properly install the screen, which, however, needs detailed and balanced coverage already in a separate article.

Gone are the days when, at the word projector, the memory obligingly drew a clumsy installation with two uncomfortable reels and a film chirping during the show. Or a heavy metal box, near which children gathered with bated breath, waiting for bright pictures on the wall. The modern device is complex installation, which has ample opportunities, without which today it is impossible to imagine seminars, master classes or presentations. And in everyday life, mounting the projector to the ceiling allows you to watch a home theater or play your favorite game as comfortably as possible.

Types and features of fasteners

The convenience of its use, as well as the safety of both the equipment itself and the children in the house, depend on the place where the installation is connected to the carrier panel. On the this moment Common types of fasteners are:

• Ceiling bracket;
• Wall bracket.

Professionals and the vast majority of private users call the projector ceiling mount the best option. Although you may encounter some difficulties during its installation, unlike wall mount, which mounts without much hassle, it is able to provide more choice of screen locations, and ensure that children cannot reach it.

High-quality installation largely depends on the competent selection of fasteners, and how correctly the methods of fastening are chosen.

Projector

Ceiling Mount Selection Criteria

The choice of fastening structure is the most important in the whole process. The strength of the entire installation, the safety of the device and your family members depends on which ceiling projector bracket you purchase.

The vast majority of such installations are made of metal, although if desired, you can find wooden or plastic varieties. The components of the structure are practically the same, the ceiling mount consists of such parts as:

• The main mounting plate, which is a strong plate mounted to the ceiling, through which the rack is attached.
• The rod is a cylinder. This is the main detail in the whole mechanism. It has telescopic qualities, which allows you to adjust the height from the ceiling, and change it as needed.
• Hardware platform. Detail, according to the structure of which the types of fasteners differ. The platform can be designed for one projector model or made in universal version, the instruction of which provides for the installation of a projector of any size. Some models provide for changing the angle of inclination of the platform in the horizontal and vertical planes.

Going for the bracket, do not forget to look at the packaging of the weight of your device. This indicator will be the main one when choosing. Make sure that the rack dimensions match the weight parameters of the model, and take into account the features of the ceiling vault.

Projector lock

The next indicator required when choosing is the correspondence of the mounting holes on the projector to the holes on the platform for it. Even a few millimeters can make DIY installation impossible.

Next, what you need to pay attention to is the length of the boom cylinder at the maximum possible lifting of the platform. Unfortunately, the height of the ceilings in many houses leaves much to be desired. And if you have low ceiling, and you did not specify this indicator, your device will not be able to perform its main function without adjusting the screen, which may be inconvenient or simply impossible.

Experienced craftsmen give advice on how to calculate the length and avoid mistakes. Knowing the height of the room, subtract the distance from the floor to the screen from this indicator. Acceptable error should not exceed 10 cm.

And last but not least important indicator to consider is the surface of the ceiling. Standard fasteners are designed only for horizontal planes. In the event that you plan to install the projector in a room where the upper vault runs obliquely, you need to purchase an additional adapter. With it, you can independently install the bracket not only to sloping ceiling, but also to a beam or rail.

The ideal option would be the selection of individual fasteners that fully comply with all indicators of the room. Many reputable companies specializing in the production of fasteners have long practiced the production of not fixed sets, but individual parts, from which you can always make the necessary kit. This includes not only the choice of stand elements for the brand of the projector, but also the selection of matching colors and even shades.

Mounting fasteners

Ceiling mount installation

Installing the projector mount mechanism should begin by determining a location on the ceiling. At this stage, you need to think about how they will be, where they will pass, and how to disguise them.

Not many will agree to put up with wires hanging like vines in the jungle. Convenient and easy to hide wires under stretch ceiling or decorative plasterboard details. It will not be difficult to carefully lay them on wooden surface. But with materials such as concrete or brick, you will have to tinker. It will be necessary to ditch the surface, and after laying the cables into it, close the gaps.

Therefore, experts advise to time the installation to repair work in the apartment, or mount ceiling bracket simultaneously with the installation of a suspended or stretch ceiling.

In the event that the projector is purchased after the completion of all home improvement work, there is only one way out, which is to purchase cable channels. They have a neat appearance, and will not spoil the design of the room.

Mounting rules are the same for all types of fasteners, and do not depend on design features. The work does not require special skills and special tools. Enough of those devices that are available in every home.

Required tools:

• Marking pencil;
• plastic dowels;
• Perforator;
• self-tapping screws;
• Screwdriver;
• Screwdriver.

Project Rack Installation Instructions

1. Remove all parts from the packaging and check that they match with each other and with the projector.
2. Attach the mounting panel to the surface, and mark the hole locations with a marker. Be sure to mark through the panel holes, otherwise a mismatch may occur.
3. Make holes of the required depth with a puncher, and install the dowels.
4. Start the screws with a screwdriver, and then firmly screw them in with a screwdriver.

False ceiling mounting features

Suspended drywall structures are able to withstand a fairly large weight. In the event that you have a miniature projector, and the total weight together with the bracket does not exceed 5 kg, the question of how to hang the projector from a false ceiling should not bother you.

To install more massive models, you need to find where the metal profiles are laid and attach the bracket to them. Finding profile strips is not at all difficult; an ordinary magnet will help in this matter.

You can also use another way, this is to cut a hole in the drywall, and fix the structure on the main carrier panel. This option only seems more time consuming, in fact, doing the work, in this way, it is much easier to hide all the wires, and the cut hole is easily masked by polyurethane sockets.

Very convenient and reliable fastening for installation on suspended models is a dowel - a butterfly. For it, you will need to drill holes exact in its diameter, and firmly fix the installation.

Armstrong ceiling mounting

This is the most convenient and hassle-free type of ceiling. His hallmark are separate drywall slabs that are simply inserted into the cells of the main frame. To mount the mount under the projector bracket, you must perform the following steps:

• Remove one or more plates;
• Install a socket next to the mounting panel of the bracket, and connect a power cable dressed in a corrugation to it;
• Apply markings on the plate through which the bracket tripod will come out, and cut the desired hole in it;
• Install finished slabs to its rightful place.

The only inconvenient moment is the cable along the wall. But here the cable channel will come to the rescue. Today, many manufacturers produce such products in various colors. Therefore, you do not have to worry about violating the harmony of the interior.

Installing the bracket to the stretch ceiling

Stretch ceilings cause the most trouble. It is impossible to install, which is already mounted, on your own. This will require partial or complete dismantling. Therefore, if, according to the designer's intention, tension models are planned for you, install the bracket for the projector in advance.

This order will also facilitate the work of the masters, they will be able to immediately determine where it is necessary to make a hole in the canvas, before the tension is performed.

Before you go shopping for a ceiling mount:

• Set to the nearest centimeter the height of the room where the projector will be placed.
• Write down all the parameters of the screen and its location.
• Consider Features ceiling covering and its powers.
• Make sure you have all the necessary tools in the house.
• Find out the diameter of the mounting holes on the projector itself, and be guided by this size when buying dowels and self-tapping screws.
• Orient yourself which decorative details you will need to mask the cable.

Hanging a projector is not an easy task!

If you do not know how to hang the projector, then this material will help you figure out this simple matter. In fact, this task is quite simple and, with the simplest tool, it becomes quite feasible for everyone. The only thing you need to decide on is the installation location:

• on the ceiling
• on the wall,
• installation on a plane (table, shelf or cabinet).

By the way, in the latter version, you will not even need tools - just install the device and adjust the image. But the first two cases require drilling a ceiling or wall, which is complicated if the ceiling is stretched or the walls are sheathed with drywall.

So, the question of how to hang the projector from the ceiling is solved in a simple way: there are many different variations of brackets and hangers, as is the case with mounting on the wall. However, even here it is possible to do without extra costs and make hanging shelf himself. Of course, you should not complicate it too much, since everything has already been invented before you, but if you have the desire and opportunities, you can make something of your own. But first things first.

How to hang a projector from the ceiling

This is what the projector hanger looks like.

Let's figure out how to hang the projector on the ceiling. In this case, you need to take into account many nuances, so you have to focus a little. This table describes how to install the projector on the ceiling.

Be careful not to shake the projector or damage the lamp. By the way, you can immediately install lamps for the Panasonic projector - they are most resistant to mechanical stress.

How to hang the projector on the wall

Another solution is to place the projector on the wall

Now let's figure out how to hang the projector on the wall. You will need the same set of tools as in the case of placing on the ceiling. The only difference is that you will use a different type of bracket that is suitable for this particular case. The main thing is to choose correct height projector placement. Read the instructions for the device to calculate correct angle and screen distance. Then perform all the same steps as with the installation on the ceiling.

In both of these cases, make sure that the projector is securely attached to the bracket. Drop the device from high altitude fraught with serious damage. Even if the device itself and the lenses remain intact, the lamp will almost certainly break. In this case, our catalog of lamps for projectors will help you. In it you will find lamps for any model of any manufacturer.

Properly placed projector is the key to its successful operation.

It is quite possible to organize high-quality leisure time at home. An excellent solution to this problem can be the use of a home theater. Installing the projector on the ceiling will help you create a magical cinema atmosphere at home and enjoy high-quality image and sound at any time.

This modern device confidently took place in many areas of life. No one is surprised to use the projector at school or university, for presentations, exhibitions or training courses. The advantages of this equipment were appreciated by the organizers of celebrations, holidays and parties. If you have decided to arrange a home theater, then watching movies, photos and videos will become much more convenient.

At home, the location of the projector should be convenient and safe for all family members. There are two options for mounting the tripod: on the wall and on the ceiling. From a safety point of view, it is better to mount the projector on the ceiling. The advantages of this mounting option are obvious. The device does not occupy a vital space in the room, it can be hidden with the help of decor. And most importantly - the screen for the projector can be located anywhere in the room. It would be wise to purchase a second set of wires and cables in case you need to move the machine to another location.

Height calculation and design selection

Suspension for the projector ceiling is a metal or plastic construction. It consists of several elements, the main one is the bar. This is the part that adjusts the installation height of the projector. In addition to the rod, the ceiling mount includes a mounting plate and a mounting platform. With the help of the plate, the device is securely fixed to the ceiling. The projector is placed directly on the platform.

The choice of mount cannot be random. In this case, you need to take into account all the necessary parameters, namely the weight of the projector and the length of the holder. A projector tripod must have a margin of safety to withstand the required load. And also, you need to take into account in advance at what height the screen will be, and the height of the room. Experts recommend mounting the projector at such a height that its level coincides with top edge screen.

Installation work

Before installing the projector on the ceiling, please read the instructions and prepare necessary tools. The device is fixed to the ceiling with dowels and self-tapping screws. It is convenient to make holes with a puncher, especially if the ceiling is concrete. In case of plasterboard ceiling device must be attached to metal profile, not to the sheet itself. As a result, the structure must be securely and safely fixed to the ceiling.

How to properly remove the wires so as not to spoil appearance rooms? Ideally, a place for cables should be provided at the repair stage. During construction works a channel is arranged in the ceiling and wires are laid in it according to all the rules. In this case, the projector will fit well into the interior of the room and even become its highlight if the mount is original.

The situation is advantageous if the ceiling is made of plasterboard or suspended "armstrong". In the space between base and false ceiling all communications will be perfectly hidden and electrical sockets.

If the repair in the apartment has already been made and the above options are not suitable, you can remove the wires into the cable channels. This method is not very successful for aesthetic reasons, but it is simple and safe.

When installing a projector, you need to decide on which surface the image will be projected. white wall, paper, sheet, projection screen look white - what's the difference between them? The screen canvas for the projector has unique reflective properties that allow you to display the image with the highest quality. Other surfaces lack these properties. Therefore, it is necessary to decide on the choice of the screen.

Types of projection screens

When choosing a screen for a projector, you need to know what they are. Basically, there are two types of screens:

• stationary
• mobile (portable)

Stationary wall screen - a reliable durable design. Screens of this type can be stretched and rolled. The tension screen is attached to the frame of various materials and is always in the expanded position. Suitable for rooms where the projector is used constantly. The disadvantage of the screen is that it is impossible to collapse and hide it.

roll screen more convenient at home. It can be minimized and unfold immediately before viewing. More simple models deployed manually, using a spring mechanism. But for more comfort created a screen for a ceiling-mounted projector with an electric drive. The design is easy to control using the control panel. With the touch of a button, the screen is easily activated and ready to display the image. In the same way, the electric drive quickly retracts it when necessary, without distracting spectators at the event.

Mobile canvases are characterized by low weight and the ability to change positions. The most popular screens on a tripod. However, in cramped conditions, the use of such structures is associated with inconvenience. The screen can be accidentally dropped by someone in the household or pets. There is a danger of damaging the surface.

mobile screen on a tripod

Note that no matter what type of screen you choose, additional options in the form automatic operation devices will create the maximum comfortable conditions when watching movies and other videos.

clock with projector

Progress in the world household appliances and electronic technology is amazing. In life modern man a variety of gadgets appear to facilitate and improve it. More recently, another electronic novelty was released - a clock with a projector on the ceiling.

Video: advantages of a watch with a projector

Projection clock - a device capable of reproducing the image of the dial on any surface, including the ceiling. Information is transferred using LEDs. It is convenient to use the device both in the dark and during the day - the projection is always clear. A watch with a projector is a good purchase for people with poor eyesight, as the projected numbers are large.

The manufacturers of this "miracle of technology" provided a large number of additional features, thanks to which the watch becomes an important assistant in everyday life. The most commonly used alarm clock has a snooze function. In this case, you will never oversleep for work. In addition, the clock may be provided with a calendar indicating the day, month, year and day of the week. You can store in the watch's memory important dates and family birthdays.

More expensive models may have a built-in radio, thermometer, and barometer. Latest measuring instruments help people whose well-being depends on weather conditions. The undoubted advantage of the device is that you can choose the color of the projection and the size of the numbers. It should be noted that red numbers are best perceived.

It is best to choose a watch based on your needs. Agree, it makes no sense to pay for a lot of additional functions, using the watch only for its intended purpose. When buying, you need to check the package, there must be an adapter. It will protect the device in case of a power outage.

September 1 is approaching - the day when parents take their children to school, and for a short time they themselves turn into children, standing on the ruler, and remembering, perhaps, best years in my life (although it didn’t seem so then, did it? ;))

So it's time for our little one to join the knowledge of full program. I hope he doesn’t come and say, like that Vovochka: “Why didn’t you warn me that this badyaga is for ten years!”, Although we expect anything.

How we ended up in the school, where I also studied until the seventh grade inclusive, is a separate story, I can only say that I did not pay for admission. But at the first meeting it turned out that the money for the renovation of the classroom and plastic windows(and the old ones were installed, apparently, even before my birth, about 30 years ago, and they did not inspire confidence in the health of children in winter) no. On all this, of course, parents chipped in.

In addition, a young progressive class teacher advised us to buy a projector for the class, because It will help diversify the learning process. If she really uses it, then I am FOR it with both hands and fully support her (unlike many parents, who, in my opinion, did not understand what the hell it was for, but chipped in money, for which I thank them).

Through the efforts of my beloved wife, the purchase of everything necessary and the installation of the projector fell on my not very fragile shoulders. , I already told. I myself followed the same path, and eventually came to. It suited me with everything, except for the lack of a VGA output, but there were already financial restrictions imposed by the parent committee, so in the current configuration, the teacher will have to poke cables from the monitor and projector when she wants to output an image to one of the devices.

Having bought everything, I turned to a friend, by the way, also a specialist in projection technology, for help. Gathering our strength, and choosing an “unnecessary” Saturday, we left my missus to cook “for washing work” (especially since guests were supposed to arrive) and went to school. Why didn't we contact a specialized company for installation? There are several reasons for this:
1. Extremely limited budget for the entire installation. More money my parents refused to collect, and only offer what kind of equipment, but with the inclusion of the installation fee, I didn’t want to, I still do it for children (and I’m not used to doing something for the sake of an excuse)
2. The wife said: “Are you a projector or what? You constantly fiddle with your site, advise others, and then you can handle it "
3. I myself thought: “What am I, not a man or something?”. And yes, there is experience.

Our school is a general education school. Built in the 70s. Ceiling height - 3 meters.

So. The task is to hang the projector so that the screen optimal size hung in front school board, when necessary, without touching or distorting the picture, and retracting when it is not needed. To ensure that the image from the projector is even, clear and hits the screen. The installation was complicated by the presence of this very board and a clock on the wall. Plus you need to lay 10 meters power cable and 12.4 meters of VGA cable so that later the firefighters would not dig into the poor electrician, who is already having a hard time doing nothing (judging by the wiring at the school and his appearance; he came in to admire what was happening).

Solution:
Choose the right projector. As I said, in my case it turned out to be . We select the screen right size and format. For a projector with an aspect ratio of 4:3 under conditions limited budget I chose, the declared width of which is 180 cm, and the aspect ratio is 1:1. This size, in my opinion, is perfect for kids sitting on any row - the first row of desks is about 2.5-3 meters from the screen, the last one is about 6-6.5 meters.

We go to my page and calculate from what distance this projector will give us a picture of the required width. At the same time, it should be taken into account that in my case the screen had a black frame (it visually improves the volume of the image and it is more convenient to install the projector with it, especially if it is more convenient without lens shift) 3 cm wide on each side, which reduced the usable width of the surface to 174 see. I don’t have the EB-X02 projector in the calculator (an oversight that I plan to fix), but there is its analogue in terms of optics - EB-X10, so we all counted on it. It turned out that our screen was covered from a distance of 2.6 to 3.1 meters. In order not to miss, we stopped at a distance of 2.8 meters.

We drill holes for the ceiling mount. In this case, it has a rod length of 43-65 cm, thanks to which we were able to install the projector without applying vertical keystone correction, while hanging it high enough so that the kids would not accidentally demolish it, for example, waving backpacks.

I will warn against one mistake those who plan to install the projector. Some people figure out the location of the screen without first hanging the projector, but placing it, for example, on a table and displaying a picture. They hang a screen under it and, having calculated its center horizontally, are going to install the projector under the ceiling. This does not take into account that many projectors have an off-center lens, which means that during the above steps, the picture will not get on the screen, because. turning the projector upside down will shift the image to the side. Naturally, this is true for devices without lens shift (after all, a great invention in projector construction). Trying out the placement of a projector bolted to the mount to fit the image onto the screen is a challenge. Therefore, I prefer to first install the projector, and after that, after displaying the image on the wall, find the places for attaching the screen.

With holes in the ceiling, the first ambush awaited us. The floor slabs turned out to be very hollow, so the thickness of the “rock” into which the dowel was driven was no more than two centimeters, and the dowels themselves, which came with the mount, turned out to be soft, which is why they are driven into a hole of a smaller diameter than necessary ( for amplification) was not possible. I didn’t want to run to the store for some anchors, so I had to finalize the design in an old-fashioned way - with the help of matches

The next step was the screen, which was decided to be installed under the ceiling, and not on the wall, since the 1: 1 format made it possible to lower it quite low after installation. There was already a matter of technology (more precisely, a puncher, dowels, hooks and matches).

After installing the projector and screen, the most dreary task remained - attaching a socket to the ceiling (this is also sometimes forgotten), laying cable boxes and the cables themselves. Here, as they say, it does not hurt as much as they are tired of tumbling, making holes in the ceiling and moving a stepladder.

Bottom line: 5 hours of work, 4 smoke breaks, a pack of chips, a bottle of water and childish joy in the eyes of an almost first grader. I haven’t seen the class teacher yet, but if I didn’t call after watching, then everything is in order, and she said thanks in advance by phone.
