Hard Math for Elementary School: Workbook

"Hard Math for Elementary School: Workbook" is a workbook to accompany the textbook of the same name. Together the books aim to provide kids who are not challenged by their regular schoolwork with lessons that are harder, deeper, and more fun. The "Hard Math" textbook (sold separately) is designed to supplement what kids are getting in school. It has chapters related most standard textbook topics: addition with carrying; multiplication; fractions; etc. It covers other important topics -prime numbers, counting, probability -that are being squeezed out of many curricula. And it has chapters on topics which may not be as important-tiling floors, solving number puzzles, squaring big numbers in your head, making polyhedra out of marshmallows and toothpicks-but that make the book more fun and develop higher-level reasoning skills. "Hard Math for Elementary School: Workbook" is an important accompaniment to the textbook. It contains more than 100 worksheets. Each worksheet contains challenging questions that help students solidify their understanding of the material that is explained in the corresponding section of the textbook. Problems in the "Hard Math" workbook are hard. Some are very, very hard. This reflects the author's view that hard is fun. Hopefully, talented students will come to enjoy feeling good when they get problems right instead of feeling bad whenever they get one wrong. Many worksheets contain "Making Connections" problems that reinforce what students have learned in previous chapters and "Challenge" problems that will make many teachers reach for their copy of the answer key.
