Between 1 April 2019 and 31 October 2021— estimated from Telegram’s id allocation, not measured. How this range is calculated.
6 measurements spanning 13 days, net +22. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 8,558–8,597 and does not start at zero.

ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.
ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate.

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.
Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.
Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.

Lifetime counters from Telegram’s own channel header, read 20 August 2026 — not the date at the top of this page, which is when the subscriber count was last read. Below Telegram’s rounding threshold, so these counts are exact.

Measured directly from 1 video with a duration reading, out of the posts we hold for this channel — not this channel’s whole posting history, only the sample this register has actually read. An exact reading to the second, taken from the post itself rather than from Telegram’s own rounded chrome, so it carries no ≈ mark.
Reaction mix
2,360 reactions across 32 posts, in 10 distinct kinds. The most used accounts for 38.0% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 32 of the 33 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 2,360reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 33 most recent posts we hold, published 13 July 2026 to 16 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.
Не удержусь. Еще кусочек покажу. Это второй класс. Тут дописано сравнительно немного. В четвертом пришлось теоретический материал выдавать. Из Методики арифметики не взять, его там нет. В Методике Березанской есть, да не так. У Киселева сложновато и на буквах, в общем виде.
Пришлось писать самой. Ну я уже привычная детям это читать.
Ну что там, в сети, в которой нельзя?
Я сказала, в августе, значит, в августе

На арифметику 2,3,4,5,6 классов можно записываться у @kissloveadmin как обычно.
Начнем в конце сентября.
Первый класс арифметика начнется раньше. Олеся Владимировна @olesya_zv05 меня в сентябре подменит, чтобы научить ребят писать цифры.
С октября я возьму группу как обычно.
Первый класс в этом году занимается три раза в неделю.
На арифметиках 2-6 расписания ещё нет.
Кто уже занимался в группе, СОБЕСЕДОВАНИЕ НЕ НУЖН…
Когда меня спрашивают, какая моя самая любимая школьная дисциплина, я не задумываясь отвечаю: ГЕОМЕТРИЯ.
Вообще вне конкуренции. Любовь.
Один из самых наших первых курсов, в этом учебном году получит ПЕРЕЗАПУСК.
Я наблюдала, как его проходят, и по обратной связи делала выводы.
Учить геометрии на построение сейчас редко кто умеет. Да что там, решать эти задачи не всякий педагог способен. Честнее будет сказать, что бол…
Я сняла видео для родителей и учителей, которые раздумывают: надо ли учить «пионерам, колхозам и прочим пережиткам социализма».
Несколько раз переснимала. Довольна.
Оно будет в предисловии всех четырех методичек.

Отдельно отмечу, что нумерация по советским классам и по современным не совпадает.
Пятый класс, который начнется в сентябре, это может оказаться ВАШ ШЕСТОЙ, СЕДЬМОЙ, И ДАЖЕ ВОСЬМОЙ, в зависимости от пробелов в знаниях ребенка.
Обычно к советским +1 или +2, это будет тот класс, куда сейчас зачислили ученика в обычной школе.
Поэтому можно договориться через админа @kissloveadmin о тестировании.
Как сейчас помню, было перед карантином. Снимали мы видос для Тезиса еще, ого как давно. Интервью с Лазаревым Виктором Андреевичем. Это бывший наш декан, и зав моей кафедрой.
Я тогда на факультете так часто не появлялась.
И после интервью мы разговорились. Он послушал о моих попытках разобраться в советских методиках, о том, как я их привязать пытаюсь к тому, что есть. И мягко так, но настойчиво после этого при каждо…
Русский (и развитие речи) в этом году у 5 класса начнется С НАЧАЛА СЕНТЯБРЯ, со второго числа

Showing the 12 most recent of 33 posts we hold for @Geometry1892Kiselove. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Citation-graph rank
Citation-graph rank — 374,734 of 1,583,249entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.
Forward network
Republished by
Channels on the register that have forwarded this channel's posts into their own feed.
Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
Mentions
Named by 2 registered channels — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
Appears in Telegram’s recommendations for other channels
The reverse of the list above, and a different kind of signal. This does not require this channel to have ever been asked about directly — each row below is a channel we DID ask Telegram about, whose Telegram-generated list happened to include this one. A channel can appear here with an empty list above it, because being named by someone else’s query is independent of having been queried itself.
