very good book to have fun

This book is upto my expecations. There are very good math puzzles, both educational and entertaining.

Good problems for fourth and fifth graders

I recently purchased this book for my children in third and fourth grade and I am glad that I did. The puzzles really challenge them, although some are a bit more than they can handle. While the solutions are given in the book, they are not allowed to look at them until I am completely convinced that they will not get the answer. However, I do give them plenty of clues before that option is exercised. Some of the problems are classics, for example selecting socks until you have a matching pair and drawing figures without lifting a pencil are problems that I did in grade school many years ago. My favorite problem in this book is the one that is illustrative of the growth of powers. It involves a million sugar cubes each a half inch in width. Making a cube out of them would create a cube approximately four feet wide, a rectangle would cover a tennis court but a stack would be higher than Everest. Since the first involves the cube root of a million and the second the square root, this demonstrates the significance of squares and cubes in a unique and educational way. This book is an excellent source of mathematical puzzles for students at the level of fourth or fifth grade. While none of them is really new, they are well-suited for children of that age and all three of mine enjoy them greatly, although they do get frustrated.
