## Customer Reviews

### ⭐⭐⭐⭐⭐ Really great for my gifted 2nd grader!
*by E***W on July 27, 2013*

Got this book for mind exercises over the summer - will also use it into the new school year. I highly recommend!

### ⭐⭐⭐⭐⭐ Can't be better
*by B***A on March 17, 2011*

My 4th.Grader son really has loved this book. He started from A2 level and finished A3 a few month ago. And one month ago, my friend who has 6th grader son told me that his school teacher recommended this book - actually it was A4 level- for algebra class or upper- leveled math skill. This book can definitely help kid think logically and it seems fun. It was quite hard for me, but for my son it wasn't. We sometimes play game with this book and usually my son helps me how to solve the problems.
