Utah State Textbook Commission has placed this book on its list as "Recommended Student Resource" for Mathematics / Pre-Algebra grade levels 7-12 for its emphasis on indirect reasoning skills. Test your logic and problem solving skills in geometric puzzles that create a work of art. Art Puzzles by Numbers is the most electrifying new kind of puzzle to come along in many years. These beguiling puzzles already have millions of devoted fans in Japan, where they were invented years ago. And now Art Puzzles by Numbers has been introduced to the United States where its popularity is growing enormously. The concept is cleverly simple. You start with an empty grid. The numbers to the side and above tell you "how many" squares to fill in the columns and rows. The trick is that the numbers don't tell you "which" squares to fill in-that's for you to decide through logical reasoning and by operating back and forth between the columns and the rows. Unlike the crossword puzzle, when you have finished one of these "picture logic" puzzles correctly, you've made a picture! Complete instructions are included along with 85 puzzles ranging from easy to hard. You will find puzzles of animals, sports, holidays and many, many other things that will peak the curiosity in kids, adults and seniors.
