I use this as a reference card for students when we start Preterite VS Imperfect. It covers formation of the tense in regular and irregular forms with a few practice examples, then provides a list of "buzz" words to help students identify when to use imperfect, on the back there is a detailed use of reasons for usage of the imperfect with lots of examples so students can see the tense in context. I print it up on green card stock and give it out as a reference. My students tell me that they have saved these cards and used them again when they went to college! Very helpful.
