Books by Kevin Du

This book includes 50 visual spatial puzzles which start off simple but become increasingly challenging. The harder puzzles can even stump adults. So, these puzzles can be used as fun activities for the whole family. The logical part of our brain is the left side. The right brain deals with visual spatial information. Solving visual puzzles in this book helps train both the left and right brain in a fun way. Kevin Du has been a fan of math for as long as he remembers. From creating math games to play with friends to deriving formulas on napkins while waiting at a restaurant, he always wanted to find something interesting to do with math. He was motivated to create what he called "split puzzles" while teaching elementary school kids at a library. This was a fun way to train their logic and many kids liked it and kept asking for more.
