This is from an excellent Psmith review of Alexander Zvonkin’s Math from Three to Seven: The Story of a Mathematical Circle for Preschoolers –
The most important thing to understand about mathematical circles is that the math they jam on is completely unlike the math you study in school, and also completely unlike the “competition” math that bright kids in the United States sometimes do. Both school math and competition math are primarily comprised of exercises. An exercise is a question concocted by a human being for a didactic purpose. Any bright kid with any amount of genre-savviness can immediately make a few assumptions upon being assigned an exercise. He or she can guess that the exercise is solvable in fewer than five minutes with the appropriate techniques, and that it is related to the material in the current chapter of the book. A clever student can often use psychological techniques to reverse-engineer what the teacher or the designer of the standardized test was trying to get at with the exercise, and answer it through a process of elimination or savvy guessing or pattern matching.
Solving an exercise is like hunting a neutered zoo animal. It may be a low-stress environment for polishing particular aspects of your technique, but it will not help you to survive in the wilderness. For that, you need to see people solving problems. A problem is a question of interest that comes up when somebody is trying to do something real. A problem may not be solvable by you, or by your coach, or by any human being. Even if the problem is solvable, it may require weeks or months of dedicated, painful pursuit. It may not be obvious what techniques are required to solve a problem, they may not be techniques that you know, or it may require a surprising combination of techniques. The problem is mathematical nature red in tooth and claw. There are no guardrails. There are no hints or answers at the back of the book. There is no book. It may eat you.The bread and butter of the mathematical circle is solving problems together, as a team. There is no time here for exercises; you can do that lame stuff at school. Sometimes the coach picks a problem for you, something just beyond your ability, just the thing you need to hone your edge. But sometimes the whole circle works together on a problem that nobody has the answer to and that challenges the very best members. These problems are the most important, because with them you see great minds, men older and more talented than you, stretched to the breaking point and occasionally beaten. You see them grind and grind and try every possible attack on a problem and sometimes lose anyway. And you see them not run from being defeated, but cheerfully charge in again, because losing is good for you, losing is how you know you’ve picked an opponent worthy of a man. You learn to love things that are hard. And occasionally you win, and when you win it feels like you all win, like humanity wins, because you’re all in it together, all doing something beautiful and dangerous and exemplary of the best qualities that human beings have.
