4 Introduction MATH CAN BE FUN... FUN-TABULOUS! We teachers know that practice makes perfect especially for building computation skills. The puzzles in this book have provided excellent computation practice for my entire class and have motivated my most reluctant students. Many years of experience developing and using puzzles in the classroom have convinced me that when students are engaged by activities such as the puzzles in this book, they will learn effectively and tackle new challenges. While my students are having fun solving riddles and working through mazes, they also are building essential skills: addition, subtraction, multiplication and division the building blocks of mathematics. WHAT YOU LL FIND IN THIS BOOK This book of 0 puzzles is organized by skill areas and includes: number concepts, addition, subtraction, multiplication, division, order of operations, fractions and decimals, graphing, and time. Each section targets particular subskills, which are listed in the table of contents as well as on the practice pages. CONNECTIONS TO THE MATH STANDARDS Most of the puzzles in this book target NCTM 000 objectives listed under the Number and Operations standard. These objectives include understanding ways to represent numbers, determining meanings of operations and how they relate to one another, and computing with fluency and accuracy. This book is packed with exercises that require students to use the basic operations (addition, subtraction, multiplication, and division) in a variety of patterns with whole numbers, decimals, and fractions. Riddle Time and other puzzles feature variables, symbols, and graphs that require students to use strategies outlined in the objectives listed under the Algebra standard. Such strategies include understanding patterns, relations, and functions, and analyzing mathematical equations that use variables. HOW TO USE THIS BOOK I ve been able to use these puzzles to meet a number of instructional goals: I usually assign one of these puzzles as a follow-up to a lesson. I also use these puzzles as review sheets and quizzes to monitor my students progress in a specific skill area. And because these puzzles are self-correcting, they make ideal independent and homework assignments; a correct assignment will provide a solution to a riddle or a perfect match for numbers in a puzzle. If a student s answer does not correspond with one of the answers provided or it creates a glitch in the riddle, students realize that they ve made an error and will double-check their work to arrive at the right solution. My students eagerly await math period and frequently ask for these puzzles. I m confident that your students will enjoy and benefit from this collection, too. Bob Olenych
