Support materials for the last of 40 instructional kits of the Spanish as a Second Language Strand for primary grades are contained in this supplement to Unit 10 developed for third graders. A teacher's guide for this unit, consisting of kits 37-40, gives the timetable for use of materials. These instructional aids are designed to help the teacher carry out learning activities which will provide the English-dominant child with structures and vocabulary for effective communication in a bilingual environment. Illustrations are intended to stimulate oral language and conceptual development, while the ditto masters are for making multiple copies of visuals and individual seatwork sheets for both instruction and assessment. Kit activities support a basic theme of communities around the world. Supplementary materials include words, music, and illustrations for songs (recordings available through the Fine Arts Strand); illustrated stories; format of a diary; visuals to use with how plants and animals protect themselves; dictionaries for two stories; worksheets for various grammar exercises; and illustrations about adventures, communities of the world, and occupations (derivative words). Classroom materials are in Spanish. Each kit is for a two to three week teaching period. (RS)
