These books produce superior math students. Ray's Arithmetics teach arithmetic in an orderly fashion, starting from rules and principles, building knowledge piece by piece, leading pupils from simple to complex. From the very first pages, Ray's Arithmetics incorporate what has become the scourge of today's math students - story problems. Ray's Arithmetics students learn arithmetic, increase their reading comprehension skills, and learn to think rather than plod through page after page of addition or subtraction problems with a one line direction at the top of each page.
Most early work is to be done with real objects such as fruit, counting blocks, or marbles.
Later it is to be done in the head with mental images of the objects. When children are ready to think symbolically, they gradually drop their use of objects and images and learn to compute quickly with digits. Over 120 million copies were sold in American education's golden age. Many millions of children used these Arithmetics in the generations that produced Edison and Bell and Ford. Now it's your turn.
