¡¡¡¡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 includes philosophical understandings; principles and properties of numbers; and advanced study of common and decimal fractions, measurements, ratio, proportion, percentage, powers and roots, series, business math, and geometry. it has challenging work for advanced students and basic work for slower students and can be used for grades 7 and 8, as well as for high school.
