Once I introduce a grammar topic, I like to keep students thinking about it with short activities like this one. This discrete-point activity helps learners review nominative adjective endings and distinguish between adjectives that do and don't need endings. It is intended for use after students have learned about nominative adjective endings. This activity takes no more than 10 minutes; works great as a warm-up or as a way to wrap up class, a short informal assessment of where students are at in their understanding of adjective endings. Also works as homework.
