I use this activity with Realidades 1 Tema 8A, but it is perfect for any travel unit and for the preterite.
Students read an e-mail from Carlos to his friend and then need to put all of the appropriate verbs in the preterite. By appropriate, I mean that some of them need to stay in the present tense.
Students are also asked to add words like yesterday, last week...etc.
I use this for a warm-up, in class activity, or as homework. Students can work individually or in pairs.
Thanks for looking, and make sure to check out my other Realidades 1 materials.
Have a great year!
