The Funny Little Workbook about Restless Kids

Such problems that Grigory Oster came up with will definitely not be assigned in school lessons. Because otherwise, studying at school would be too fun. This book contains problems about friendship and fighting, about cannibals and ghosts, about beaten and unbeaten, and other interesting things. In the process of solving them, not only mathematical abilities are developed but also a sense of humor. And the illustrations by Uncle Kolya Vorontsov can be looked at endlessly!
