In this pair drill students use the imperfect tense to say what the people pictured liked to do as children. The partner that asks the questions knows how his/her partner should respond.
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.
