The fun math adventure for children aged 8 and up. Grigorij Oster's absurdly funny word problems delight both young and old. Finally, math is enjoyable! 101 problems featuring tigers, deserted islands, pesky flies, grandmothers on motorcycles, and many other amusing characters in entertaining miniatures encourage even the biggest math-hater to pick up a pencil. The Russian children's author Grigorij Oster has a unique talent for presenting math problems for elementary school students in such a heartwarmingly humorous way that even the most reluctant math student not only laughs out loud but also inadvertently solves problems that no one would have expected them to tackle. This is not surprising, as Oster can tell entire stories with just a few questions: A school bag can hold no more than four fully grown hedgehogs. How many bags are needed to bring 316 fully grown hedgehogs to school?.
