*This book is all about percentages (No shock there). It is divided into two parts: Percentage Guide and 30 Printable Percentage Puzzles/Games/Activities. The Guide portion of the book has notes and examples of different situations involving percentages (such as the modeling section above). There is a premium on using an algebraic approach to solving problems in this guide, but different methods are also used. *

*The following are the sections of this guide: Percentage History Percentage, Fraction, & Decimal Conversion Modeling Percentages Percentages as Ratios Finding the Percentage, Part or Whole amounts Comparing amounts Percentage of Change Percentage of Markup Percentages with Tax and Tips Percentage of Error Simple and Compound Interest Commissions *
