We are honored and happy to bring this classic arithmetic of Joseph Ray. These popular books sell more than any other arithmetic books in the United States, in fact, more than1200,000 copies, and they are still used in modern American schools and families. As you can see, this set of arithmetic textbooks is organized in an orderly way around the subject itself.
Ray emphasizes critical thinking in his class. He thinks his students need to learn how to apply what they have learned to real life. He doesn't give his students simple problems to solve, but likes application problems. Students can improve their reading comprehension and learn to think.
