This document is the preface to the "Public School Phonic Primer, Part I". It provides guidance for teachers on how to teach reading using this primer. It recommends teaching letter sounds at the blackboard before associating letters with pictures in the book. It also emphasizes training pupils to recognize words by listening to sounds being combined, and having them do independent work without help. Most class work should focus on "ear problems" where pupils translate sounds, while the primer provides "eye problems" to solve independently.
