This is a 51-slide PowerPoint that has three sections, though the first should definitely take the most time.
1. Sentence fill-ins to discuss. Blanks are for choosing the preterit or imperfect. A reason pops up with the first click, then the conjugated verb. The vocabulary is primarily from the Avancemos 2 textbook from Unit 4.
2. Just reasons for using one or the other.
3. Little bit of conjugation practice with particular emphasis on the irregulars from preterit and imperfect that are in Unidad 4 of the Avancemos 2 textbook (car/gar/zar, querer/venir/traer/decir, etc).
