Instructions: This activity is to practice preterite tense car, gar, zar, regular and irregular verbs as well as preterite key words like yesterday, last week and last weekend. Students are paired up and each given a different worksheet. They must ask each other what they did on each of days noted with an asterisk. Students must respond based on the information provided on their own schedule, conjugating the verb in the preterite tense. Students should continue communicating until both of their calendars are complete. You can change the dates of the calendar or the verbs to suit your needs.
