Under the heading «La pereza agudiza el ingenio» I came across a funny list of interview responses to the following question:

«20 estudiantes fueron preguntados cuál es la cosa más perezosa que jamás han hecho. Algunas de sus respuestas fueron geniales…»

The answers not only seemed like something my students would get a kick out of, but also many are excellent examples of authentic sentences for practicing preterit vs. imperfect. I adapted 10 of the classroom appropriate responses to a simple grammar activity. I have students work on the activity sheet in pairs. It includes conjugation practice (conjugate verbs to preterit or imperfect to fill in the blanks in the sentences) as well as a conversation and writing prompt. Here you will also find a Powerpoint presentation for going over the activity as a group (or you could do it all together from the start). Download the activity sheet, answer key, and Powerpoint with the links below! Also, I´d love to hear any of your students´ interesting responses to the conversation prompt in a comment!
