Immerse yourself in the fascinating world of geometry and spatial ability -- either individually or in small groups, either as challenges or play problems Here are four reasons why you should work with this book:

1. Train and improve your spatial ability in a well-balanced and structured way The problems of the book address all subcomponents of spatial ability
2. Train spatial ability on all three levels in which we learn mathematics The haptic way, figurative way, symbolic and mostly mental way, or a combination of all three
3. Store geometric objects with various characteristics in the brain This enhances your ability to solve geometric and spatial and even mathematical tasks.
4. Hours of fun From the several thousand students and adults who worked with the problems of the book, we know that it is fun solving these problems in a variety of ways.

This book offers a very unique opportunity to enhance your spatial ability, your mathematical competence, and your logical thinking. The authors arranged 45 problems -- including more than 120 tasks -- in a well-balanced order, which have been tested with a variety of populations.
