Titles in Barron's Painless Series are textbook supplements designed especially for classroom use by middle school and high school students. The approach of each title is an appeal to students who think that the subject is boring, or too difficult, or both. The authors, all experienced educators, take a light approach, showing kids what is most interesting about each subject, and how seemingly difficult problems can be transformed into fun quizzes, brain-ticklers, and challenging puzzles with rational solutions. In this volume, students learn to see patterns in math word problems, then compute with decimals, fractions, compare rates, and solve proportions. Then using everyday, real-world examples, they explore statistics and probabilities, and learn how math can actually predict future outcomes and events. Other areas of practical math are examined, with a final chapter that searches out problems and activities that can be found on the World Wide Web.
