This powerpoint is an in-class review activity. It is best if used after students have had time to master regular -ar verb conjugation.
This is an activity where students pass a sheet of paper after a timer rings and will have to do a different translation/task after each pass. The first part of the activity, the students must give the correct -ar verb ending, then they must conjugate the verbs in the second portion.
You may choose to have the students pass the papers however you wish. I find it easiest if students are in rows, then they only have to snake their ways up and down the rows. If they are in groups/tables, they can pass it one person to the right each time.
