Educate your students on the importance of sound financial choices with Life of Fred's trademark humor and pizzazz. Designed to fulfill the need for personal financial literacy skills that math books don't often cover, readers will learn about income and spending ratios, debt, budgeting, setting goals, investments, and other necessary knowledge for functioning as an adult with financial solvency. . . while keeping the perspective that there are more important things than money! "Your Turn to Play" exercises are included throughout, but rather than focusing only math skills, often ask students to reflect upon their priorities, the differences between wants and needs, and where to allot items or expenses. Answers are given on the next page.
