Use this pair drill in Spanish I after you've taught all of the regular, irregular and irregular verbs in the present tense. You can also use it as a review at the beginning of Spanish II.
To use this activity, print enough copies for 1/2 of your largest class. Cut each page in half. Put students in pairs giving each person in the pair half of the sheet. When students get to the bottom of the sheet, they switch papers and do the drill again. In my classroom, students must repeat the drill until they are instructed to stop.
