Задачи со спичками. Рекомендую взять реальные палочки, фломастеры, полоски бумаги или спички в конце концов и, решая задачу, перекладывать реальные объекты.

Источник: книги Якова Исидоровича Перельмана. Одну придумала сама, потому что в источнике не было картинки, и я взяла другую, а потом поняла свою ошибку, но задачу оставила. Отдельно прекрасно видеть, как все спички нарисованы разными — художник их рисовал вручную.

#спички #смекалка
Думаю, от 3 класса и старше (в учебнике Гейдмана есть похожие), верхней границы нет, но, может, и более младшим подойдет.

Telegram | DID YOU KNOW?

"There are several million Russians who can lift their head up from propaganda and try to look for other sources, and I'd say that most look for it on Telegram," he said. If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means it’s less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isn’t as secure earned it some criticism. If you’re looking for something that is considered more reliable by privacy advocates, then Signal is the EFF’s preferred platform, although that too is not without some caveats. Perpetrators of these scams will create a public group on Telegram to promote these investment packages that are usually accompanied by fake testimonies and sometimes advertised as being Shariah-compliant. Interested investors will be asked to directly message the representatives to begin investing in the various investment packages offered. Apparently upbeat developments in Russia's discussions with Ukraine helped at least temporarily send investors back into risk assets. Russian President Vladimir Putin said during a meeting with his Belarusian counterpart Alexander Lukashenko that there were "certain positive developments" occurring in the talks with Ukraine, according to a transcript of their meeting. Putin added that discussions were happening "almost on a daily basis." "For Telegram, accountability has always been a problem, which is why it was so popular even before the full-scale war with far-right extremists and terrorists from all over the world," she told AFP from her safe house outside the Ukrainian capital.
