I use these Smart Board (or you can make an overhead transparency) activities as a warm up at the beginning of class while I take attendance. I use the first activity on one day and the second activity the following day.
My students have a partner with whom they work on activities during the week, hence Estudiante A. and B. columns.
On the first activity, students write the pronouns on their paper and the correctly conjugated form of user next to each one.
On the second activity, students write the the forms of user on their paper and the correct pronoun next to each verb.
