This is an engaging way to practice both affirmative and negative Tu Commands. There is a list of 10 expressions in the infinitive form, and students have to decide, according to the expression, whether the angel or devil on your shoulders would tell you to do this (affirmative command) and which would tell you to not do this (negative command). For each of the 10 expressions, students should write both an affirmative and negative Tu Command, so in total they will write 20 commands during this activity. This was used with my Spanish 2 class.
