This guide is intended to assist Latin teachers and English teachers with background in Latin to expand the English vocabulary and reading skills of students through the study of Latin roots, prefixes, and suffixes. It is also intended to familiarize students with aspects of classical culture and its impact; to introduce orally some basic Latin; and to stimulate interest in the study of language and the humanities. An introduction provides general notes on teaching Latin in the Philadelphia School District and notes on the use of the guide. This section includes notes on scheduling, staffing, articulation with other materials, the organization of each lesson, general teaching hints, and an overview of the material to be taught in this unit. The main part of the guide presents 13 lesson profiles and a unit review lesson. Each profile contains objectives, instructions, materials to be used, and the vocabulary and other necessary information. A selected annotated bibliography and summary of the classical pronunciation of Latin are appended. (AMH)
