Communities around the world is the theme of unit 10 of the Spanish as a Second Language Strand for grade three. Learning and assessment activities are designed to provide the English-dominant child with structures and vocabulary for effective communication in a bilingual environment. The language arts, math, and science activities help the student build concepts in his new language through formal and informal language experiences. The spiraling questions and activities deal with who the individual is--grammatical structure, future tense, review of preterit and imperfect, synonyms, comprehension and interpretation skills, decoding skills; what his alternatives are--present perfect tense, diary format, future tense, value placement and expanded notation of two and three digits, oral story reading; can the individual initiate change--verb form review, object pronouns, food chains, means of protection plants and animals have, derivatives (occupation words), dictionary skills, conflict solved through cooperation and interdependence, command form review; what the results of change are--structures and vocabulary review, addition review, subtraction of numbers up to three digits, pounds/kilograms, oral reading. Each kit contains a vocabulary and assessment activities. A pupil's reader is also included. (RS)
