Meanwhile, here are three puzzles with Russian origins. The first question was told to me recently by Nikolai Andreev, of the Steklov Mathematical Institute, part of the Russian Academy of Sciences. The second question is taken from a fantastic after-school programme run by three Russian emigres in London. They call themselves We Solve Problems, and use two approaches used in Russia: maths circles, in which students can delve deeper into topics, and maths battles, which are like the maths equivalent of a debating society. No spoilers BTL please, but do talk about great Russian mathematicians, or any experiences with Russian teaching methods.
