This is the third in a set of 36 teacher guides to the Entrepreneurial Training Modules and accompanies CE 031 034. The purpose of the module is to give students some idea of what it is like to own and operate a tree service. Following an overview are general notes on use of the module. Suggested steps for module use contain suggestions on introducing the module, a brief discussion of the nine units, responses to learning activities, suggestions for summarizing the module, and responses to the quiz. The units are Planning a Tree Service; Choosing a Location, Getting Money to Start; Being in Charge; Organizing the Work; Setting Prices; Advertising and Selling; Keeping Financial Records; and Keeping Your Business Successful. Each unit contains a case study, responses to individual activities, responses to discussion questions, and a group activity.
