This list identifies grammar concepts, communicative goals, and related vocabulary for senior seminar's second thematic unit, "Who Did I Used to Be?". Leave textbook to learn authentic, colloquial Spanish expressions per their corresponding building blocks (preterite, imperfect, present perfect, and past perfect). Distribute the English version to students at beginning of unit and bilingual version (study guide) at end. Excellent Option: Highlight (to reinforce) 4-6 words or expressions at beginning of each class as "expresiones diarias". Students appreciate learning practical, non-antiquated vocabulary of present day native speakers. Results in easier and more natural interpersonal interactions.
