Designed for use with the teacher's guide to unit eight of the social science strand developed for grade three, these support materials for Spanish-speaking children include instructional aids for classroom use and worksheets for students which may be reproduced for individual seatwork. Worksheets are to be used under supervision rather than as independent tasks. The visuals and ditto masters are to help the teacher carry out both learning and assessment activities which focus on the unit's theme--communities which make up the nation. A timetable for the use of these materials is found in the guide for kits 29-32. The supplementary materials include maps, assessment sheets, and visuals to illustrate classroom stories and to be used with study about early inhabitants of the U.S., different types of architecture, occupations, interdependence in a community and among communities, and pollution. All classroom materials are in Spanish. (RS)
