We are honored and happy to bring this classic Arithmetic by Joseph Ray. These popular books sold more than any other arithmetic in America, in fact over 120 million copies and are still used in modern American schools and families. As you can see, this set of Arithmetic textbooks is organized in an orderly manner around the discipline of arithmetic itself.Ray emphasized critical thinking in his classroom. He believed that his students needed to learn how to apply what they learned to real-life situations. Rather than giving his pupils simple problems to solve, he preferred word problems. Students can increase their reading comprehension skills, and learn to think.This book reviews basic arithmetic skills and carries them to high levels. Also covers topics of measurement, factoring, decimals, percentage, ratio, proportion, powers, roots, and geometry. It can be used for grades 5 and 6. Good mastery of this book takes a child higher than a usual grade 6 level.
