One of a series of eleven curriculum manuals which cover the four transportation topics of public transportation, transportation and the environment, transportation safety, and bicycles for elementary, secondary, and adult levels, this manual for grades 4-6 covers all four topics. Materials in four chapters comprising fourteen mini-units cover different aspects of each of the four topics. Each mini-unit consists of a lesson plan component, which provides a suggested sequence of learning activities, and an individual learning activities component, which describes in detail how to implement each exercise. Typical elementary mini-units focus on street signs, emergency vehicles, learning to ride a bike, and an introduction to the concepts of pollution and energy conservation. Most units provide opportunity to exercise basic skills in language arts, mathematics, and social interaction. Supplementary activities are included at the end of each chapter which offer additional learning activities for independent use. Also included are readings on transportation and the environment, a list of references for further study resources, and masters for reproduction of role profiles, game boards, maps, and other distributable materials. (A curriculum guide, CE 014 028, is also available for use with the manuals.) (TA)
