The second grade instructional unit, part of a grade school level career education series, is designed to assist learners in relating present experiences to past and future ones. Before the main body of the lessons is described field test results are reported and key items are presented: the concepts, the estimated instructional time, the vocabulary introduced, the resources required, and the instructor preparation tasks. Instructional procedures are presented in three sections--an introduction, learners' tasks, and a summary. Some supplemental activities are presented, strategy and resource profiles provided, assessment procedures outlined, and instructional strategies suggested. The unit's primary intent is to help the learner to understand that tasks performed in the home, at work, and in school are related to the interest, aptitude, and training of the individual performing these tasks. Emphasizing worker interdependency, the activities supporting the performance objectives incorporate multimedia resources, discussions, role playing, simulation, and games. The interdependency factor is examined as it relates to school workers, family members, between different occupations, in the community, and in interpersonal relationships. The 10-hour unit relates to the social studies area primarily, but also provides language, math, and art experiences for both group and individual instruction. (MW)
