Using 33 verbs pulled directly from the story Like Water for Chocolate, students have to identify the infinitive of the conjugated verb as well as whether the verb is conjugated in the preterite or the imperfect. With this, students are actually applying their knowledge as they analyze the verbs from an actual passage. A key is included, too.
This verb list (& key) is part of my Like Water for Chocolate/Preterite and Imperfect Unit. That whole unit is also for sale and includes: vocab list & key, story excerpt with numbered verbs, English/Spanish side-by-side version of the story, comprehension worksheet & key, preterite vs. imperfect worksheet & key, 33 verbs list for identifying preterite vs. imperfect & key, preterite vs. imperfect practice and/or quiz with keys, bingo list with numbers for calling & boards for playing.
