This power point presentation includes a review of prefixes to create opposites for adjectives. It has a practice section with answers included.
Another slide includes a real ad for a job offer and students are asked to create one on their own using adjectives of personality.
The presentation ends with a slide where students are asked to create a fictional online profile to look for the other half. In this project (I asked my students to create a poster and they loved it, they had the option to use their own pictures or bring a picture (s) from a magazine) students get another chance to practice noun/adjective agreement and it works very well. We gave then an additional set of adjectives like ambicioso, brillante, fuerte, etc.
