Decimals and Percents

Grade 5 - 7

Decimals & Percents is the second book in the Life of Fred Arithmetic Series, which is designed for students who have completed the elementary & intermediate series books, and are at least in the 5th Grade.

Thirty-three chapters are included, each of which ends with a "Your Turn to Play" segment with three or four questions. Answers are provided on the next page for students to go over themselves after attempting to solve the problems. "The Bridge" review questions are given after every five chapters, and provide transitions between concepts as well as a means of assessment. For parents who choose to use these sections as evaluation tools, it is recommended that students score at least 90% (9 out of 10 questions) before moving on. If students don't succeed, they can try again with a total of five different sets of ten problems. The book concludes with "The Final Bridge" which features twenty questions (with five tries again provided). Answers to the Bridge questions are provided in the back of the book.

Life of Fred is a unique, complete (not supplemental), math program that uses a highly engaging narrative to teach math without fear and with enjoyment. Students follow the life of Fred Gauss (a math professor who grows up to the age of six), who has many humorous, unlikely, and zany adventures over the course of the curriculum. Math becomes relevant and important because the need for math occurs in Fred's life (and he sees math everywhere). Witty and truly entertaining, these books will engage students in a way unlike any other math program, while also instilling a solid understanding of the principles of mathematics without an abundance of repetitive drills. This series is perfect for inquisitive students who struggle with the relevance of math, or anyone looking for a creative approach to mathematic thinking!

192 pages, indexed; hardcover, non-consumable textbook with Smyth-sewn binding. Students write their answers on separate paper. Answers are also included in the text and written directly to the student.
