This Marketing I curriculum guide contains ten units of instruction that may be taught as they are or used in conjunction with the teacher's own instructional materials. The ten units, which may be presented in any order, include (1) Orientation/Job Interview, (2) Communications, (3) Human Relations, (4) Mathematics, (5) Selling, (6) Cashier/Checker, (7) Sales Promotion, (8) Credit, (9) Economics, and (10) Career Orientation. Each of the units may contain some or all of the following parts: outline, objectives (each measured by a student activity or by a test), competency statements, numerical listing of competencies, equipment/supplies, curriculum content section, student activities, handouts, transparency masters, tests and keys, audiovisual aids, and references. Curriculum content sections contain resource columns where student activities, handouts, transparency masters, tests, and some audiovisual aids have been keyed in at the point where they may be used most effectively. Handout sections begin with two vocabulary lists--the first includes definitions, the second does not. (YLB)
