Description:
<p>For some time now, I have tutored both children and adults in math and</p><p>science. Along the way, I have picked up, and devised, some amusing math</p><p>tricks. This book is a collection of such tricks, all based on relatively</p><p>simple mathematical concepts.</p><p>While I hope the book, and tricks, will be amusing and enjoyable in</p><p>themselves – I also hope they can serve an educational purpose:</p><p>If you are reading the book, you may learn – or at least improve your</p><p>understanding of – key mathematical concepts. Wherever possible, I</p><p>have explained the mathematical concepts and ideas that underlie</p><p>each trick.</p><p>If you are a parent, teach, or tutor, you can use the trick to awaken a</p><p>child's interest in mathematics: show them the trick, amaze them, and</p><p>then teach them how to do the trick themselves. When you explain</p><p>the trick, be sure to explain the mathematical reason why it works.</p><p>Many of the tricks involve some aspects of arithmetic, for example</p><p>adding, subtracting or multiplying numbers. Doing a trick with a</p><p>child affords an excellent opportunity to encourage the child to</p><p>practice those operations.</p><p>So, have fun with this book – and enjoy the tricks – and the math!</p>
