Mathematics Plus. A Collection of Engaging Tasks for 3rd Grade Students

This year the "Plus" Olympiad will take place, and we invite you to participate in it. In this book, you will find tasks that were in the "Plus" Olympiad last year - for example, with mats and garland diagrams. And... then there will be new problems - one more difficult than the other! On the pages of this notebook, you will encounter encrypted letters and numbers, multi-headed dragons, cleverly broken chocolates, and much more interesting stuff. Having mastered this notebook, you will become a master of carpet laying and a true specialist in counting candies. But will you manage to find the correct nets of a cube and guess who lives on Uncle Grisha's farm? . .Some problems are indeed not easy, but we are confident that you will overcome them. . . We hope you will enjoy the book!
