Older children, or those who have finished the Primary book, go on to Ray's New Intellectual Arithmetic: mental arithmetic, fractions, ratio and percentage, also with a guide for every lesson.

What is Ray's Arithmetic?

Joseph Ray (1807–1855) grew up on a farm in what is now West Virginia, studied medicine, and then spent his life teaching mathematics in Cincinnati, at Woodward High School and Woodward College. His first arithmetic came out in 1834. Over the next decades it grew into a series, from a first book for small children to a higher arithmetic for older students, and it became one of the most widely used schoolbooks in America, alongside McGuffey's Readers from the same Cincinnati publishers.

After Ray's death the series was revised and reissued in 1877 as Ray's New Arithmetics, the edition most homeschoolers use today, and the one on this page. The method is simple and thorough: count real things first, learn each table by heart, then use it straight away in short story problems, and explain every answer in a full sentence. Old prices and measures aside, the arithmetic is the same today.
