FRACTIONS, DECIMALS, AND PERCENTS PRACTICE CAN BE FUN!If fluency and accuracy are the goals you have established for your students learning fractions,decimals, and percents, then they should partake in regular review and practice with theseskills. The key to motivating students is to provide them with a variety of activities that areinteresting and stimulating. To support my students as they gain fluency and accuracy, I havecreated skill-building practice puzzles that they really enjoy.

WHAT YOULL FIND IN THIS BOOKThis book offers a collection of 40 fraction, decimal, and percent activities for a broad range of skills and abilities. The puzzles begin with fractions, then progress to decimals and percents.Within each skill, they are arranged from easy to difficult. You can match the needs of your students and target a specific skill by checking the detailed skill description listed both in theTable of Contents and on each activity page.

While many of the activities address a broad range of skills, some highlights of this bookinclude the activities that reinforce two skillsexpressing written numbers first as fractions,then as decimals. For example, one problem might read twenty-six and thirteen thousandths.Students must first express this as a fraction, then as a decimal. Next, students must use thedecimal answer to complete the cross-number puzzle. You can assign this type of activity at anytime during the school year once the concepts have been taught, as it serves as an excellentreview of these skills.

HOW TO USE THIS BOOKBe sure to use these puzzles in a way that best suits the needs of your class. You may find ithelpful to assign certain puzzles as practice work to follow a lesson, as in-class review work, or as homework. Where necessary, be sure to remind students that if they need more room to compute, they can use the back of the sheet or a piece of scrap paperdepending on your class policy. Whether they are solving a riddle or determining the missing numerator or denominator, students are motivated to check each problem so that they can finish the puzzlesuccessfully.

CONNECTIONS TO THE MATH STANDARDSMost of the puzzles in this book target NCTM 2000 objectives listed under the Number andOperations standard. These objectives include understanding ways to represent numbers, determining meanings of operations and how they relate to one another, and computing withfluency and accuracy. This book is packed with exercises that require students to use fractions,decimals, and percents in a variety of formats.

I am confident that your students, like mine, will enjoy this collection of puzzles and reap thebenefits of practicing these essential skills.
