Item Weight ‏ : ‎ 1.55 pounds.This 124 page text is a manual for teachers and students studying the Nemeth Braille Code which was adopted by the Braille Authority of North America in 1987. From the Preface: "This manual is a text for learning those parts of the Nemeth Code likely to be used in elementary school, junior high school, and high school mathematics, the levels collectively referred to at several points in the manual as 'school mathematics' as distinguished from higher mathematics. It is designed for use in teacher-training programs, but it may also serve to teach the Nemeth Code to new braille readers in upper grades and high school, and even as a self-teaching text for individual teachers. The unique feature of this manual is that the material is presented sequentially, one group of symbols and applicable rules at a time. Each new symbol and rule is illustrated, and each group of related new rules is followed by practice exercises for the student. No illustration includes symbols or transcription practices which have not yet been explained. The choice of symbols and concepts to be included was made after examination of thousands of pages of elementary, junior high, and high school mathematics texts.
