Are you looking for an easy way to get a lot of repetitions of high frequency verbs in the imperfect tense?
Tell your students to bring a photo to class or to email a photo of themselves doing something when they were little. Put the photos in a powerpoint or share the photos using a document camera. Start by asking ¿Cómo se llama él/ella? (What is his/her name?) and then ¿Qué hacía él/ella cuando era niño/a? (What did s/he did when s/he was a little boy/girl?) After the students answer, talk directly to the student who is in the photo to get exposure to the tú form. For the example of the little girl at the beach, ask:
- To what beach did you used to go?
- With whom did you used to go to the beach?
- For how many days did you used to stay at the beach?
- What things did you do at the beach?
and then mix it up and ask if she still goes to the beach or if she only did that when she was little.
You can easily find a handful of questions for each photo. You don't need to be concerned that the students will tire of the repetition. My students are so interested in seeing photos of their friends when they were younger that they appear not to notice the repetition or, if they do, they don't mind it.
I use this activity each year with my Spanish 2 students. The photos provide the opportunity for highly personalized questions, complete with actively engaged students and, most definitely COMPELLING and comprehensible input.
Note: If you have a student that doesn't have photos available of when they were younger, make sure you have a plan B for those students so they don't feel left out. A nice twist that may be an option for Plan B, is for some students to bring in photos of their grandparents or great-grandparents. Then you can talk about what the older generations used to do which may evolve into an interesting talk about the differences of growing up now compared to growing up several decades ago.
