What should a child's inquisitive mind do? How to teach him to think outside the box? This collection is the perfect helper for parents and teachers! Inside you will find numerical puzzles, spatial thinking puzzles, optical illusions, and even magic tricks with ordinary objects that train memory and attention, develop analytical thinking, and teach you to find non-obvious solutions. Yakov Perelman had a remarkable gift for turning complex theories into fascinating stories. The tasks in his books are like dumbbells for the mind: regular "training" with them makes thinking sharper and memory stronger.Such reading is a great way for schoolchildren to fall in love with mathematics and physics; for adults, it is an opportunity to test their logic and erudition; for teachers, it is an inexhaustible source of non—standard tasks. The book is great for schoolwork, family activities, and even adult mind training. See if you can solve the problems that once baffled Soviet schoolchildren!
