The Idea Tree suggests a variety of ideas for using community resources in classroom activities. Several suggestions are made under each of the following headings: student assignments (individual activities, for later sharing, dealing with enrichment of the resource topic or to supplement background information); small group assignments; whole class activities; games (activities utilizing some form of competition or problem solving, that indirectly or directly deal with the resource topic); display activities (utilizing artistic abilities to enrich the resource person's topic through visual stimuli); career days (often involving more than one class); miscellaneous activities; and supplementary media (suggestions for cassettes, filmstrips, records, posters, books, that can be utilized to secure some additional information).
