Will Shortz Presents I Can KenKen! Volume 1: 75 Puzzles for Having Fun with Math

started doing ken ken then our 10 yrs okd grandson became interested in it and i ken ken book was handed over to him. he loves his math class and excels in it and this book will enhance his calculations without use of calculator for multiplications or divisions nor his fingers for simple subtractions or additions.

Bizarre ! You open the front cover and the book is upside down and back to front. Strange - is this the first puzzle? Prompt delivery though.

This is a terrific book of math puzzles for kids. They start of easy (using only the numbers 1, 2, & 3) and get harder (using the numbers 1-6). I bought volume 2 for my 9-year-old to keep his brain active over the summer. He LOVES it so I ordered this one, and volume 3, too. These puzzles are great for problem solving and critical thinking. The puzzles are similar to sudoku (sp?), but not quite the same. It says this book is for kids ages 9-12, but I think my son could have done these when he was 7 or 8. He has an EXTREMELY mathematical mind. If your child is older (11-12) and also has a mathematical mind, you might try some of the kenken books for adults. I highly recommend this book!

Sent to grand kids. They enjoy doing these and feel great accomplishments when they get the math puzzles figured. Helps them do better in school.

Purchased this for my wife who loves word puzzles and Sudoku. Recommend starting with the easier ones first till you get the hang of it and then move to the harder ones. If you like Sudoku, good chance you will like these also. Okay honey, I wrote your review, now can I have supper?
